AbstractThe nonretinotopic portion of the macaque pulvinar complex is interconnected with the occipitoparietal and occipitotemporal transcortical visual systems where information about the location and motion of a visual object or its form and color are modulated by eye movements and attention. We recorded from single cells in and about the border of the dorsal portion of the lateral pulvinar and the adjacent medial pulvinar of awake behaving Macaca mulatta in order to determine how the properties of these two functionally dichotomous cortical systems were represented. We found a class of pulvinar neurons that responded differentially to ten different patterns or broadband wavelengths (colors). Thirty-four percent of cells tested responded to the presentation of at least one of the pattern or color stimuli. These cells often discharged to several of the patterns or colors, but responded best to only one or two of them, and 86% were found to have statistically significant pattern and/or color preferences. Pattern/color preferential cells had an average latency of 79.1 ± 46.0 ms (range 31–186 ms), responding well before most inferotemporal cortical cell responses. Visually guided and memory-guided saccade tasks showed that 58% of pattern/color preferential cells also had saccade-related properties e.g. directional presaccadic and postsaccadic discharges, and inhibition of activity during the saccade. In the pulvinar, the mean presaccadic response latency was earlier, and the mean postsaccadic response latency was later, than those reported for parietal cortex. We also discovered that the strength of response to patterns or colors changed depending upon the behavioral setting. In comparison to trials in which the monkey fixated dead ahead during passive presentations of pattern and color stimuli, 92% of the cells showed attenuated responses to the same passive presentation of patterns and colors during fixation when these trials were interleaved with trials which also required active saccades to pattern and color targets in the periphery. We conclude that properties which represent the functionally dichotomous object and spatial visual systems are found together in single pulvinar neurons and that the responses of these cells to pattern or color stimuli are influenced by the focus of spatial attention. The pulvinar is the first structure in the brain shown to have neurons which integrate both object and spatial properties and the response latencies indicate that this information is processed before that in cortex. These results are discussed in terms of role of the pulvinar in visual attention as well as its unique role in providing both object feature and spatial location information to the inferotemporal cortex.

AbstractTo localize objects during active sensing, animals must differentiate stimuli caused by volitional movement from real-world object motion. To determine a neural basis for this ability, we examined the mouse superior colliculus (SC), which contains multiple egocentric maps of sensorimotor space. By placing mice in a whisker-guided virtual reality, we discovered a rapidly adapting tactile response that transiently emerged during externally generated gains in whisker contact. Responses to self-generated touch that matched self-generated history were significantly attenuated, revealing that transient response magnitude is controlled by sensorimotor predictions. The magnitude of the transient response gradually decreased with repetitions in external motion, revealing a slow habituation based on external history. The direction of external motion was accurately encoded in the firing rates of transiently responsive neurons. These data reveal that whisker-specific adaptation and sensorimotor predictions in SC neurons enhance the localization of unexpected, externally generated changes in tactile space.

Affect. During the Second World War, London and other European cities were subjected to the terrors of aerial bombardment, rendered through nightmarish anticipations of the bomber (Gollin 7) and the material storm of the real air-raid. The fall of bombs plagued cities and their citizens with the terrible rain of explosives and incendiary weapons. A volatile landscape was formed as the urban environment was ‘unmade’ and urged into violent motion. Flying projectiles of shrapnel, debris and people; avalanches of collapsing factories and houses; the inhale and exhale of compressed air and firestorms; the scream of the explosion. All these composed an incredibly fluid urban traumatic, as atmospheres fell over the cities that was thick with smoke, dust, and ventilated only by terror (see for instance Sebald 10 and Mendieta’s 3 recent commentary). Vast craters were imprinted onto the charred morphologies of London and Berlin as well as Coventry, Hamburg and Dresden. Just as the punctuations of the bombing saw the psychic as well as the material give way, writers portraying Britain as an ‘volcano island’ (Spaight 5) witnessed eruptive projections – the volleys of the material air-war; the emotional signature of charged and bitter reprisals; pain, anguish and vengeance - counter-strikes of affect. In the midst of all of this molten violence and emotion it seems impossible that a simultaneous sense of quiescence could be at all possible. More than mere physical fixity or geographical stasis, a rather different sort of experience could take place. Preceding, during and following the excessive mobilisation of an air raid, ‘stillness’ was often used to describe certain plateuing stretches of time-space which were slowed and even stopped (Anderson 740). Between the eruptions appeared hollows of calm and even boredom. People’s nervous flinching under the reverberation of high-explosive blasts formed part of what Jordan Crandall might call a ‘bodily-inclination’ position. Slackened and taut feelings condensed around people listening out for the oncoming bomber. People found that they prepared for the dreadful wail of the siren, or relaxed in the aftermath of the attack. In these instances, states of tension and apprehension as well as calm and relief formed though stillness. The peculiar experiences of ‘stillness’ articulated in these events open out, I suggest, distinctive ways-of-being which undo our assumptions of perpetually fluid subjectivities and the primacy of the ‘body in motion’ even within the context of unparalleled movement and uncertainty (see Harrison 423 and also Rose and Wylie 477 for theoretical critique). The sorts of “musics of stillness and silence able to be discovered in a world of movement” (Thrift, Still 50), add to our understandings of the material geographies of war and terror (see for instance Graham 63; Gregory and Pred 3), whilst they gesture towards complex material-affective experiences of bodies and spaces. Stillness in this sense, denotes apprehending and anticipating spaces and events in ways that sees the body enveloped within the movement of the environment around it; bobbing along intensities that course their way through it; positioned towards pasts and futures that make themselves felt, and becoming capable of intense forms of experience and thought. These examples illustrate not a shutting down of the body to an inwardly focused position – albeit composed by complex relations and connections – but bodies finely attuned to their exteriors (see Bissell, Animating 277 and Conradson 33). In this paper I draw from a range of oral and written testimony archived at the Imperial War Museum and the Mass Observation wartime regular reports. Edited publications from these collections were also consulted. Detailing the experience of aerial bombing during the Blitz, particularly on London between September 1940 to May 1941, forms part of a wider project concerning the calculative and affective dimensions of the aeroplane’s relationship with the human body, especially through the spaces it has worked to construct (infrastructures such as airports) and destroy. While appearing extraordinary, the examples I use are actually fairly typical of the patternings of experience and the depth and clarity with which they are told. They could be taken to be representative of the population as a whole or coincidentally similar testimonials. Either way, they are couched within a specific cultural historical context of urgency, threat and unparalleled violence.Anticipations The complex material geographies of an air raid reveal the ecological interdependencies of populations and their often urban environments and metabolisms (Coward 419; Davis 3; Graham 63; Gregory The Colonial 19; Hewitt Place 257). Aerial warfare was an address of populations conceived at the register of their bio-rhythmical and metabolic relationship to their milieu (Adey). The Blitz and the subsequent Allied bombing campaign constituted Churchill’s ‘great experiment’ for governments attempting to assess the damage an air raid could inflict upon a population’s nerves and morale (Brittain 77; Gregory In Another 88). An anxious and uncertain landscape constructed before the war, perpetuated by public officials, commentators and members of parliament, saw background affects (Ngai 5) of urgency creating an atmosphere that pressurised and squeezed the population to prepare for the ‘gathering storm’. Attacks upon the atmosphere itself had been readily predicted in the form of threatening gas attacks ready to poison the medium upon which human and animal life depended (Haldane 111; Sloterdijk 41-57). One of the most talked of moments of the Blitz is not necessarily the action but the times of stillness that preceded it. Before and in-between an air raid stillness appears to describe a state rendered somewhere between the lulls and silences of the action and the warnings and the anticipatory feelings of what might happen. In the awaiting bodies, the materialites of silence could be felt as a kind-of-sound and as an atmospheric sense of imminence. At the onset of the first air-raids sound became a signifier of what was on the way (MO 408). Waiting – as both practice and sensation – imparted considerable inertia that went back and forth through time (Jeffrey 956; Massumi, Parables 3). For Geographer Kenneth Hewitt, sound “told of the coming raiders, the nearness of bombs, the plight of loved ones” (When the 16). The enormous social survey of Mass Observation concluded that “fear seems to be linked above all with noise” (original emphasis). As one report found, “It is the siren or the whistle or the explosion or the drone – these are the things that terrify. Fear seems to come to us most of all through our sense of hearing” (MO 378). Yet the power of the siren came not only from its capacity to propagate sound and to alert, but the warning held in its voice of ‘keeping silent’. “Prefacing in a dire prolepsis the post-apocalyptic event before the event”, as Bishop and Phillips (97) put it, the stillness of silence was incredibly virtual in its affects, disclosing - in its lack of life – the lives that would be later taken. Devastation was expected and rehearsed by civilians. Stillness formed a space and body ready to spring into movement – an ‘imminent mobility’ as John Armitage (204) has described it. Perched on the edge of devastation, space-times were felt through a sense of impending doom. Fatalistic yet composed expectations of a bomb heading straight down pervaded the thoughts and feelings of shelter dwellers (MO 253; MO 217). Waves of sound disrupted fragile tempers as they passed through the waiting bodies in the physical language of tensed muscles and gritted teeth (Gaskin 36). Silence helped form bodies inclined-to-attention, particularly sensitive to aural disturbances and vibrations from all around. Walls, floors and objects carried an urban bass-line of warning (Goodman). Stillness was forged through a body readied in advance of the violence these materialities signified. A calm and composed body was not necessarily an immobile body. Civilians who had prepared for the attacks were ready to snap into action - to dutifully wear their gas-mask or escape to shelter. ‘Backgrounds of expectation’ (Thrift, Still 36) were forged through non-too-subtle procedural and sequential movements which opened-out new modes of thinking and feeling. Folding one’s clothes and placing them on the dresser in-readiness; pillows and sheets prepared for a spell in the shelter, these were some of many orderly examples (IWM 14595). In the event of a gas attack air raid precautions instructions advised how to put on a gas mask (ARPD 90-92),i) Hold the breath. ii) Remove headgear and place between the knees. iii) Lift the flap of the haversack [ …] iv) Bring the face-piece towards the face’[…](v) Breathe out and continue to breathe in a normal manner The rational technologies of drill, dressage and operational research enabled poise in the face of an eventual air-raid. Through this ‘logistical-life’ (Reid 17), thought was directed towards simple tasks by minutely described instructions. Stilled LifeThe end of stillness was usually marked by a reactionary ‘flinch’, ‘start’ or ‘jump’. Such reactionary ‘urgent analogs’ (Ngai 94; Tomkins 96) often occurred as a response to sounds and movements that merely broke the tension rather than accurately mimicking an air raid. These atmospheres were brittle and easily disrupted. Cars back-firing and changing gear were often complained about (MO 371), just as bringing people out of the quiescence of sleep was a common effect of air-raids (Kraftl and Horton 509). Disorientation was usually fostered in this process while people found it very difficult to carry out the most simple of tasks. Putting one’s clothes on or even making their way out of the bedroom door became enormously problematic. Sirens awoke a ‘conditioned reflex’ to take cover (MO 364). Long periods of sleep deprivation brought on considerable fatigue and anxiety. ‘Sleep we Must’ wrote journalist Ritchie Calder (252) noticing the invigorating powers of sleep for both urban morale and the bare existence of survival. For other more traumatized members of the population, psychological studies found that the sustained concentration of shelling caused what was named ‘apathy-retreat’ (Harrisson, Living 65). This extreme form of acquiescence saw especially susceptible and vulnerable civilians suffer an overwhelming urge to sleep and to be cared-for ‘as if chronically ill’ (Janis 90). A class and racial politics of quiescent affect was enacted as several members of the population were believed far more liable to ‘give way’ to defeat and dangerous emotions (Brittain 77; Committee of Imperial Defence).In other cases it was only once an air-raid had started that sleep could be found (MO 253). The boredom of waiting could gather in its intensity deforming bodies with “the doom of depression” (Anderson 749). The stopped time-spaces in advance of a raid could be soaked with so much tension that the commencement of sirens, vibrations and explosions would allow a person overwhelming relief (MO 253). Quoting from a boy recalling his experiences in Hannover during 1943, Hewitt illustrates:I lie in bed. I am afraid. I strain my ears to hear something but still all is quiet. I hardly dare breathe, as if something horrible is knocking at the door, at the windows. Is it the beating of my heart? ... Suddenly there seems relief, the sirens howl into the night ... (Heimatbund Niedersachsen 1953: 185). (Cited in Hewitt, When 16)Once a state of still was lost getting it back required some effort (Bissell, Comfortable 1697). Cautious of preventing mass panic and public hysteria by allowing the body to erupt outwards into dangerous vectors of mobility, the British government’s schooling in the theories of panicology (Orr 12) and contagious affect (Le Bon 17; Tarde 278; Thrift, Intensities 57; Trotter 140), made air raid precautions (ARP) officers, police and civil defence teams enforce ‘stay put’ and ‘hold firm’ orders to protect the population (Jones et al, Civilian Morale 463, Public Panic 63-64; Thomas 16). Such orders were meant to shield against precisely the kinds of volatile bodies they were trying to compel with their own bombing strategies. Reactions to the Blitz were moralised and racialised. Becoming stilled required self-conscious work by a public anxious not to be seen to ‘panic’. This took the form of self-disciplination. People exhausted considerable energy to ‘settle’ themselves down. It required ‘holding’ themselves still and ‘together’ in order to accomplish this state, and to avoid going the same way as the buildings falling apart around them, as some people observed (MO 408). In Britain a cup of tea was often made as a spontaneous response in the event of the conclusion of a raid (Brown 686). As well as destroying bombing created spaces too – making space for stillness (Conradson 33). Many people found that they could recall their experiences in vivid detail, allocating a significant proportion of their memories to the recollection of the self and an awareness of their surroundings (IWM 19103). In this mode of stillness, contemplation did not turn-inwards but unfolded out towards the environment. The material processual movement of the shell-blast literally evacuated all sound and materials from its centre to leave a vacuum of negative pressure. Diaries and oral testimonies stretch out these millisecond events into discernable times and spaces of sensation, thought and the experience of experience (Massumi, Parables 2). Extraordinarily, survivors mention serene feelings of quiet within the eye of the blast (see Mortimer 239); they had, literally, ‘no time to be frightened’ (Crighton-Miller 6150). A shell explosion could create such intensities of stillness that a sudden and distinctive lessening of the person and world are expressed, constituting ‘stilling-slowing diminishments’ (Anderson 744). As if the blast-vacuum had sucked all the animation from their agency, recollections convey passivity and, paradoxically, a much more heightened and contemplative sense of the moment (Bourke 121; Thrift, Still 41). More lucid accounts describe a multitude of thoughts and an attention to minute detail. Alternatively, the enormous peaking of a waking blast subdued all later activities to relative obsolescence. The hurricane of sounds and air appear to overload into the flatness of an extended and calmed instantaneous present.Then the whistling stopped, then a terrific thump as it hit the ground, and everything seem to expand, then contract with deliberation and stillness seemed to be all around. (As recollected by Bill and Vi Reagan in Gaskin 17)On the other hand, as Schivelbusch (7) shows us in his exploration of defeat, the cessation of war could be met with an outburst of feeling. In these micro-moments a close encounter with death was often experienced with elation, a feeling of peace and well-being drawn through a much more heightened sense of the now (MO 253). These are not pre-formed or contemplative techniques of attunement as Thrift has tracked, but are the consequence of significant trauma and the primal reaction to extreme danger.TracesSusan Griffin’s haunting A Chorus of Stones documents what she describes as a private life of war (1). For Griffin, and as shown in these brief examples, stillness and being-stilled describe a series of diverse experiences endured during aerial bombing. Yet, as Griffin narrates, these are not-so private lives. A common representation of air war can be found in Henry Moore’s tube shelter sketches which convey sleeping tube-dwellers harboured in the London underground during the Blitz. The bodies are represented as much more than individuals being connected by Moore’s wave-like shapes into the turbulent aggregation of a choppy ocean. What we see in Moore’s portrayal and the examples discussed already are experiences with definite relations to both inner and outer worlds. They refer to more-than individuals who bear intimate relations to their outsides and the atmospheric and material environments enveloping and searing through them. Stillness was an unlikely state composed through these circulations just as it was formed as a means of address. It was required in order to apprehend sounds and possible events through techniques of listening or waiting. Alternatively being stilled could refer to pauses between air-strikes and the corresponding breaks of tension in the aftermath of a raid. Stillness was composed through a series of distributed yet interconnecting bodies, feelings, materials and atmospheres oriented towards the future and the past. The ruins of bombed-out building forms stand as traces even today. Just as Massumi (Sensing 16) describes in the context of architecture, the now static remainder of the explosion “envelops in its stillness a deformational field of which it stands as the trace”. The ruined forms left after the attack stand as a “monument” of the passing of the raid to be what it once was – house, factory, shop, restaurant, library - and to become something else. The experience of those ‘from below’ (Hewitt 2) suffering contemporary forms of air-warfare share many parallels with those of the Blitz. Air power continues to target, apparently more precisely, the affective tones of the body. Accessed by kinetic and non-kinetic forces, the signs of air-war are generated by the shelling of Kosovo, ‘shock and awe’ in Iraq, air-strikes in Afghanistan and by the simulated air-raids of IDF aircraft producing sonic-booms over sleeping Palestinian civilians, now becoming far more real as I write in the final days of 2008. Achieving stillness in the wake of aerial trauma remains, even now, a way to survive the (private) life of air war.

Being is an empty fiction. The “apparent” world is the only world: the “true world” is just a lie added on to it… —Nietzsche. Anna Poletti: I’m attracted to autobiography in a non-narrative context because I’m very interested in texts that people create that demonstrate their thinking or their fantasies or their processing, generally.Lauren Berlant: Right, in that sense it’s autobiography in your larger sense of what autobiography is: a record of […] processing. —Anna Poletti and Julie Rak with Lauren Berlant. The medium is the message. —Marshall McLuhanWelcome to the M/C Journal issue on automediality. If “automediality” sounds like another academic buzzword to you, you are right. But it is more than a buzzword for scholars interested in exploring the significant role of mediation in auto/biographical engagement. Automediality is, we think, an incredibly useful way of framing and grouping scholarly investigations of the processes and practices that people engage when they mediate their lives and selves in a range of auto/biographical forms.We are incredibly excited to bring you this vibrant collection of research about what we are calling “automediality,” but first it is useful to lay some groundwork in terms of explicitly articulating what we think automediality is and does, and why we think it is necessary.As life writing scholars exploring contemporary examples of digital auto/biography in our own research, we were both struck by the need for a new definition of auto/biography that expands beyond text, beyond narrative, beyond subject in any complete sense or form, to reflect the multiplicity of ways that lives are lived and recorded using new media today. We each found ourselves limited, at times, by existing assumptions about what auto/biography traditionally is. Sidonie Smith and Julia Watson, in their field defining work Reading Autobiography, offer an etymological cue that summarises the prevailing use and perception of autobiographical work: “in Greek, autos denotes ‘self,’ bios ‘life,’ and graphe ‘writing.’ Taken together in this order, the words self life writing offer a brief definition of the autobiography” (1).If “autobiography” has denoted a way to write the self from the location of the self, automediality points to the range of media forms and technologies through which people engage in digital, visual, filmic, performative, textual, and transmediated forms of documenting, constructing and presenting the self. Smith and Watson introduce automediality as a possible theoretical framework for “approaching life storytelling in diverse visual and digital media” (Reading 168). Originally developed by European scholars such as Jörg Dünne and Christian Moser, the term was introduced in order “to expand the definition of how subjectivity is constructed in writing, image, or new media” (Smith and Watson Reading 168).Conjoining autos and media, the concept redresses a tendency in autobiography studies to consider media as “tools” for rendering a pre-existent self. Theorists of automediality emphasize that the choice of medium is determined by self-expression; and the materiality of the medium is constitutive of the subjectivity rendered. Thus media technologies do not simplify or undermine the interiority of the subject but, on the contrary, expand the field of self-representation beyond the literary to cultural and media practices. New media of the self revise notions of identity and the rhetoric and modalities of self-presentation, and they prompt new imaginings of virtual sociality enabled by concepts of community that do not depend on personal encounter. (Reading 168)Looking at auto/biographical practices from a framework of automediality moves away from a conception of texts as able to capture and transmit preexisting selves, lives and identities, and towards an understanding of selves, lives and identities as constructed by and through textual and media practices. It is through creating an autobiographical text that the “self” a person thinks they are comes into being. The mode of creation here, be it a Facebook status update, a memoir, or an alt account, for example, is situated within networks of power, meaning and social capital to shape ways of being a “self” in a particular environment or context. Automedial reading takes all of these formative elements into consideration.Julie Rak suggests that automedia “describes the enactment of a life story in a new media environment” (155), but we think that the term is even more useful as a framework or approach to studying not only new media life stories, but auto/biographical practices as they are enacted in a range of media forms, analogue and digital alike. Importantly, our aim here is not simply to introduce another buzzword, but rather to draw attention to the current need to rethink the significant role of mediation in auto/biographical production, performance, and practices. As Rak points out, “it is time not only to rename the practices we study, but also to think critically about online life as life, and not as the texts many of us are more used to studying, which are meant to represent a life” (156). This kind of critical rethinking about how media is embedded in the living of lives, and the scholarly shift that Rak suggests from examining representation in texts to examining “online life as life” is crucial to the notion of automediality. And it has us—the editors of this issue—divided. A Conversation between EditorsÜmit: choosing “subject” and “process” over “text.”I think what automediality is, which is different to auto/biography, is process rather than product. Automediality allows us to explore how our lives intertwine with different mediums and technologies resulting in new subjects, but subjects in motion. There is no product, there is no complete narrative, there is no snapshot that captures the subject. The subject is always developing, always in motion, always in the “process of doing” (Rak 156), of being and becoming. It is a “moving target” as Smith and Watson suggest (“Virtually” 71). And therefore, automediality, as Rak suggests, is the process of living: living in relationship with media. Where as an autobiographical enquiry has usually (not always) involved the study of a subject in a complete form (although susceptible to other “versions”)—a text in other words, which can be examined by itself—an automedial enquiry has to adapt to the fact that there isn’t a product that can be examined in isolation. As Emma has argued elsewhere, we can never hold “a single cohesive version” of automedial subjects in our hands and we never reach “the end” of a subject’s self-representation as long as they continue to “post” (“Self-Branding” 75). What we are exploring as scholars of automediality is a process of living. How people live, create and present themselves, participate, narrativise, and simply “be” in different spaces, using different mediums and technologies. The mediated lives and subjects that we’re exploring in this issue require new language, new words and definitions. We are not dealing with “texts,” although there are textual components, we are not dealing with “narratives,” although one (or many) is (or are) always in formation (see Rak 156), and most importantly, we are not dealing with “products,” that hold any significance in isolation. What we are dealing with are processes: processes of being, doing, creating, and distributing the self, in relationship with media and their affordances, limitations and participants. My objection to language such as “text” is that it implies something tangible, taking for granted the ephemerality of the subjects of automediality. So often in my research I have taken a “snapshot” of a subject (in the form of a YouTube video, for example) and treated it like a text ready for analysis only to find when I revisit it that it has changed, been edited or contradicted, or completely erased (see Kennedy). And when we treat “snapshots” as “texts” for analysis I think we miss the most important point: that is the process through which the subject was and is being formed (in relationship with the medium, its technologies, and the people and things that congregate and participate in that space). We need to expand the way we explore mediated subjects and lives and “automediality” allows us to do this—it gives us a “space” in which to develop new language and methods of enquiry.Emma: texts are vital to studying automediality.Elsewhere, I have suggested that textuality is key to a definition of automediality: “The aim of an automedial approach is to discover what texts can tell us about cultural understandings of selfhood and what it means to portray ‘real’ life and ‘real’ selves through media. The emphasis is on thinking critically about mediation” (Girls, 22). However, Ümit’s thinking about automedia as process has been instrumental to progressing how I am defining and thinking about automediality. For me, though, (and perhaps my background in literary studies is showing here), framing autobiographical production and performance as texts that we can read is a useful framework that allows us to disentangle and examine abstract, slippery concepts like being, living, identity, and selfhood in process in a way that brings the roles and effects of mediation into sharp focus.Retaining the terminology around texts and textual practices—specifically that branch that is concerned with cultural production—also means that we can observe the labour of auto/biography, which is important for thinking about the economies in which automediation occurs as well as acknowledging the work that goes into creating these self-presentations or performances. It takes skills, labour, literacies, and—for me—nuanced understanding and facility with crucial modalities of reading to participate and "play" in any kind of media form. My definition of reading is broad: people read meaning, identities, lives, media, and the world around them in order to figure out how they fit into any given context, and it is the texts produced in even the most fleeting or participatory automediation that record or hold traces of this work, this process, that we as scholars can then examine.The spirit in which I apply “text” is deeply influenced by the field of semiotics within Cultural Studies. The work of semioticians like Saussure, Althusser, Derrida and Lotman that I studied during my undergraduate degree leads me, like many literary scholars, to think about not only cultural products like books and media as texts, but also bodies, surfaces, ephemeral and immaterial performances, and a range of autobiographical practices as texts. As agents we create meaning by reading, decoding, interpreting, and negotiating texts. The work of mediation, for me, is deeply connected to textual practices.I still think that texts—as well as the practices and processes that go into creating, distributing, and reading them—are a productive framework for examining strategies of self-presentation and identity performance. However, Ümit’s observations around process (articulated in her short essay “Vulnerability” and developed here) is particularly vital to thinking about the context for the participation of produsers in media economies where automedial production is often fleeting, ephemeral, and in flux. And I think that the importance of process in analysing more (apparently or materially) stable media is important, too. One way of thinking about a middle ground between text and subject is by considering the concept of becoming as central to the conceptual framework of automediality. Ümit: finding a middle ground.I agree our difference of opinion about viewing these subjects as texts comes from our different disciplines. For you, Emma, the word “text” is important because it emphasises the agency and labour involved in its creation. As a communications and media scholar, I operate on the assumption that communicating the self involves a huge amount of conscious and unconscious work. I take the agency and labour involved in mediating the self for granted. I still have an issue with “text,” however, as taking the process through which it was created for granted. I do concede, though, that we can’t completely disregard the products of mediation, because there are products (as long as we agree that they are in motion), and these are worthy of study.Although mediated subjects and texts can be fleeting and ephemeral, the fact that they are mediated, as you suggest, means that to some extent they are traceable. The mediation of the self means we can see and track its progression, its influencers, its forms, its relationships and dialogues. Although it is changeable and deletable, “doing” (living in relationship with media) leaves a record. On YouTube, for example, I can see the interactions that take place, through comments, likes and subscriptions, and I can therefore trace the subject as it changes. Mediating the self in this way materialises the process of self-formation. Automediality illuminates the process and makes it accessible to us to research. I think the concept of becoming is a perfect middle ground. “Becoming” as a Middle GroundWe are interested in using the concept of automediality to unpack and examine how selves and lives are brought into being through media forms by examining, simultaneously, both the process of mediation and the product (i.e. the autobiographical subjects and text). A crucial part of this examination is attending to the process of construction, of the process through which the textual self is mediated. One way of thinking about this in relation to the construction of lives and selves, is by thinking about how the concept of becoming is traceable in mediation.Rob Cover’s discussion of becoming in social networking is influential to our thinking here. Cover, drawing on Judith Butler, explains that underlying his approach is “the idea that identity and subjectivity is an ongoing process of becoming, rather than an ontological state of being” (56) and he argues that looking at the practices and artifacts of online identity performance can reveal the intricacies of identity in process. Also important here is the work of Stuart Hall who, in 1989, wrote about becoming in terms of how it is implicated in identity as a cultural practice or process:Cultural identity […] is a matter of 'becoming' as well as of 'being'. […] It is not something which already exists, transcending place, time, history and culture. Cultural identities come from somewhere, have histories. But, like everything which is historical, they undergo constant trans-formation. Far from being eternally fixed […], they are subject to the continuous ‘play’ of history, culture and power. Far from being grounded in a mere 'recovery' of the past, which is waiting to be found, and which, when found, will secure our sense of ourselves into eternity, identities are the names we give to the different ways we are positioned by, and position ourselves within, the narrative of the past. (70)Hall’s description of becoming as the process by which identity is continually brought into being has parallels to how we are thinking of mediation and life narrative in this issue. Hall is speaking about reading and representing identity, about the processes and products through which people enact, express, perform, and consume identity categories. Similarly, we are looking at subjectivities and identities in process, and we both agree that automediality as a conceptual tool and classifying label turns our attention to the ways in which people identify themselves and others using media. Media use, here, encompasses practices of engagement in terms of both consumption and creation. And, increasingly, users participate by engaging in both production and consumption simultaneously, becoming produsers—a term coined by the editor of this journal, Axel Bruns (2). Bruns’s notion of produsers illustrates the complex relationship between consumers, producers and users in the current media economy (2). One of the significant aspects of an automedial enquiry is the blurring of boundaries between creators and consumers. Automedial subjects are created in dialogue with the other participants in the space. The lives and identities are not only merged with the medium and technologies involved in their creation, but also with the other produsers in the space. This is critical when we begin to explore how to research automediality, as an automedial enquiry demands automediation of the researcher. In order to explore these subjects, the researcher must participate, to some extent, in the practice. Exploring subjects on social media, for example, requires the researcher to create an account and therefore participate in the same activity they are observing/consuming/researching.Questions for Automedial EnquiryTaking these ideas from theory to practice, from our point of view, reading auto/biographical texts and practices through a framework of automediality involves asking some of the following questions and paying attention to some of the following elements:What are the affordances, constraints and features of this medium that have shaped how a subject can inscribe, perform, or construct a self-presentation? As Nancy Baym writes, “our ability to construct an online self-presentation ... is limited and enabled by the communicative tools, or affordances, a platform makes available and our skills at strategically managing them” (124).What networks of power traverse this technology, this medium, and thus this mode of self-presentation?How does this performance of selfhood engage the different autobiographical “I”s: the narrating self and the narrated self; the subject and its creator; the online self and the offline IRL (in real life) self or selves. Although, as Smith and Watson state, “theorists of media and autobiography […] approach the constructed self not as an essence but as a subject” (Reading, 71), we have to acknowledge the person or constructs that exist outside of (and informs) the performance. How do these different facets of the self, and identities, speak to each other in automedia? In what networks of production and consumption does the automedia exist? How is the audience positioned in relation to the text or subject?Surface reading: the textual elements that form the interface between reader and story can tell us about what forces are shaping the self-presentations within the text, and also how the reader is positioned in relation to the autobiographical narrative. What does a surface reading reveal about how the self is being constructed by both media conventions and cultural meanings? The possibility of multiple and fragmented selves. The self that a subject performs or creates in one media platform may be a very different self that they perform in another or that they feel themselves to “be” in “real” life. What is the relationship between these selves? How do they inform and speak to each other?Authenticity is always suspect. Rather than a concrete guarantee that the media presentation correlates truthfully or sincerely to the IRL (in real life) identity or life of the narrator, authenticity in automedia is “an effect created by the form and style” of an auto/biographical performance (Maguire Girls, 11; drawing on Poletti Intimate, 28-9; emphasis added). Thus, it is less useful to weigh up how authentic or how real a particular self-presentation or media form is, and more interesting to examine how particular media constructs or creates effects of authenticity, or makes appeals to truth/authenticity. And finally, method: How can we develop methods to explore automedia which critically examine the text/subject, as well as the “process of doing” (Rak) through which the text/subject is being and “becoming” (Hall). Introducing the ArticlesEach of these excellent articles responds to technological effects on selfhood. By canvassing a range of media forms and approaches to conceptualising the mediation of lives and selves, our contributors’ ideas probe new directions for automediality as a framework for reading and thinking through self-mediation.The feature article, authored by Anna Poletti and Julie Rak, proposes that RuPaul’s Drag Race demonstrates automedia in action and suggests that the reality TV show, by modelling “queer time,” presents a challenge to dominant (straight) patterns of temporality in life narratives. This piece presents an argument for considering how identities that have been positioned as marginal are able, through automediality, to reconfigure understandings of what a life and a self can look like.Wes Hill addresses a key claim that we are making when we talk about autmediality: that media interfaces and contexts shape and construct the forms of selfhood that are brought into being through them. Hill takes the case study of artist and filmmaker Ryan Trecartin and argues that Trecartin’s videos demonstrate a fragmented set of identities that are deeply constituted by a style of performance that Hill calls “Internet-era camp.” Here, Internet-era camp becomes a mode through which to constitute the self through fragmented sets of intertextual and affective meanings. Emily van der Nagel highlights the multi-faceted nature of the mediated self through her investigation of Alt (alternative) accounts on Twitter. Her article demonstrates the way people use different accounts on the same platform for different facets of the self, and for different audiences. Isabel Pederson and Kristen Aspevig extend our discussion of automediality to explore agency and consent in the example of children producing their own automedial subjects and texts on YouTube, in the form of toy reviews. Kylie Cardell explores the digital self-tracking device many of us wear on our wrists, the Fitbit, and asks whether this wearable technology constitutes a diary. In her article, Cardell examines how a Fitbit can become an almanac for self-improvement, where the constant tracking of our physical behaviour changes the way that we live.Anu A Harju critically examines the world of “fatshion” blogging to reveal the relational way “fatshionistas” are formed in dialogue with medium, community and market. Harju situates the self as a product of relations, “borne out of them as well as dependent on them.” Chad Habel takes up masculine gender performance in video games by investigating how genre facilitates (or doesn’t) particular modes of identification by coaxing aggressive gameplay.Mick Broderick, Stuart Marshall Bender and Tony McHugh take a look how artificial intelligence technologies are currently being used to create immersive virtual reality experiences. They question the use of trauma in such projects, and suggest that affect—particularly when used to explore suffering within virtual worlds—needs careful thought moving forward with these technologies.ConclusionThis collection of interdisciplinary scholarship is an exploration of the different ways that people mediate the self. Focusing on mediation as a process that brings the subject into being, these essays explore the connections between lives, selves, identities and media technologies. The textual constructs that hold selves together become traces or products that can perform social functions, but they also have immense richness as objects of study. By taking apart and examining the processes and effects of mediation on life narratives, as scholars we are able to re-focus the microscope on the becoming of lives, selves and identities that are constructed in autobiographical texts. In seeking contributions for this collection, we were guided by two key questions: How do people mediate their identities, selves and experiences? How do media forms and conventions limit or facilitate the possibilities for particular kinds of selfhood to be articulated? Scholars of life narrative warn us that “the self” is not a unified and pre-existing entity that can simply be transcribed or translated through media. Rather, the self is brought into being through writing—or mediation. Media technologies like the camera, the diary, social media platforms, and books each have conventions, affordances, abilities and limits that both enable and restrict the kinds of self-presentation that are possible. Particular media bring particular subjectivities to life. It is our opinion that examining such sites and modes of automediality can tell us about the ways in which “technologies and subjectivity” are connected (Smith and Watson “Virtually” 77), and this is what we hope this collection of work offers to scholars of media and life narrative, as well as those working in interrelated fields. But this is only the beginning. The interfaces between life narrative and media technologies remains an exciting space for new ideas and theories to flourish.Future avenues for investigation of automediality might include examining: the platforms, mediums and technologies of automediality; the affordances of automediality for alternative narratives and identities; the vulnerabilities of mediated narratives and identities; the mediated self as brand/consumable product; cases that explore when automediality is lasting and permanent and when it is ephemeral and shifting; and multiple methodologies for investigating the mediated self, particularly in the context of digital media. An upcoming development that we’re particularly excited about is Anna Poletti’s forthcoming monograph Biomediations which will, we expect, move this thinking forward again.We hope that this issue of M/C Journal inspires more ideas about how media shapes the kinds of selves we think we are, now, in the past, and into the future.

Cette thèse explore les méthodes d'apprentissage auto-supervisé pour la localisation d'objets, communément appelées « Object Discovery ». La localisation d'objets dans les images et les vidéos est un élément essentiel des tâches de vision par ordinateur telles que la détection, la ré-identification, le suivi, etc. Les algorithmes supervisés actuels peuvent localiser (et classifier) les objets avec précision, mais ils sont coûteux en raison de la nécessité de données annotées. Le processus d'étiquetage est généralement répété pour chaque nouvelle donnée ou catégorie d'intérêt, limitant ainsi leur évolutivité. De plus, les approches sémantiquement spécialisées nécessitent une connaissance préalable des classes cibles, restreignant leur utilisation aux objets connus. La découverte d'objets vise à pallier ces limitations en étant plus générique. La première contribution de la thèse s'est concentrée sur la modalité image, en étudiant comment les caractéristiques des modèles transformers de vision auto-supervisés peuvent servir d'indices pour la découverte d'objets multiples. Afin de localiser les objets dans leur définition la plus large, nous avons étendu notre étude aux données vidéo, en exploitant les indices de mouvement et en ciblant la localisation d'objets capables de se déplacer. Nous avons introduit la modélisation de l'arrière-plan et la distillation de connaissances dans la découverte d'objets pour résoudre le problème de la sur-segmentation de l'arrière-plan dans les méthodes existantes, et pour réintégrer les objets statiques, améliorant ainsi de manière significative le rapport signal/bruit dans les prédictions. Reconnaissant les limites des données à modalité unique, nous avons incorporé des données 3D à travers un apprentissage par distillation de connaissances cross-modale. L'échange de connaissances entre les domaines 2D et 3D a permis d'améliorer l'alignement des régions d'objets entre les deux modalités, rendant possible l'utilisation de la cohérence multi-modale comme critère de confiance
This thesis explores self-supervised learning methods for object localization, commonly known as Object Discovery. Object localization in images and videos is an essential component of computer vision tasks such as detection, re-identification, tracking etc. Current supervised algorithms can localize (and classify) objects accurately but are costly due to the need for annotated data. The process of labeling is typically repeated for each new data or category of interest, limiting their scalability. Additionally, the semantically specialized approaches require prior knowledge of the target classes, restricting their use to known objects. Object Discovery aims to address these limitations by being more generic. The first contribution of this thesis focused on the image modality, investigating how features from self-supervised vision transformers can serve as cues for multi-object discovery. To localize objects in their broadest definition, we extended our focus to video data, leveraging motion cues and targeting the localization of objects that can move. We introduced background modeling and knowledge distillation in object discovery to tackle the background over-segmentation issue in existing object discovery methods and to reintegrate static objects, significantly improving the signal-to-noise ratio in predictions. Recognizing the limitations of single-modality data, we incorporated 3D data through a cross-modal distillation framework. The knowledge exchange between 2D and 3D domains improved alignment on object regions between the two modalities, enabling the use of multi-modal consistency as a confidence criterion
