Full textLo scopo principale del sistema visivo dell'uomo è quello di costruire un modello interno del mondo per poter interagire con esso. Tale modello ,presumibilmente funge da impianto di riferimento per pensieri ed azioni. Milner e Goodale (1995) hanno proposto una teoria sul funzionamento del sistema visivo (TVSH) secondo la quale il sistema svolgerebbe le funzioni di (l) cognizione visiva e di (2) trasformazione sensomotoria in maniera indipendente. Alla base di questi due sottosistemi funzionali ci sarebbero due rappresentazioni differenti. Prova di questo modello viene dalla dimostrazione di Aglioti e Goodale (1995) che l'illusione di Ebbinghaus influenza i processi di cognizione visiva (percezione) ma non i processi visivi deputati al movimento (azione). In questi ultimi anni è stata prodotta una mole rilevante di dati sulle dissociazioni percezione-azione, in forte contrasto tra loro. È stata fatta una rassegna della letteratura più recente in cui sono state usate le illusioni visive con soggetti non affetti da deficit neurologici e un'analisi delle ipotesi alternative alla TVSH che cercano di spiegare questi dati. Questo lavoro si occupa di percezione visiva e controllo motorio nello spazio peripersonale. È stato studiato il processo di trasformazione visuo-motoria che avviene quando si giudica un'illusione di estensione con un compito motorio di puntamento. In tre serie di esperimenti sono state richiesti dei giudizi percettivi e motori di stimoli che riproducevano la dumbbell illusion, l 'illusione di compressione di Kanizsa, una variante dell'illusione di Brentano e l 'illusione di Miiller-Lyer. Oltre a dimensioni, orientazione e tipo di stimoli, sono state variate il tipo di azione (puntamento contro riproduzione) e il feedback visivo (open-loop contro closed-loop). Si è verificato il ruolo dei movimenti oculari saccadici in un questo tipo di compito. I risultati ottenuti mostrano che anche quando un giudizio visivo è influenzato da un illusione è possibile ottenere dei giudizi motori accurati. Le condizioni cruciali per l'osservazione di queste dissociazioni sono il tipo di codifica egocentrica contro allocentrica, l'utilizzo di feed-back visivo durante l'azione, la posizione nello spazio dove viene eseguita l'azione rispetto a quella dello stimolo. Anche se il modello TVSH fa una distinzione troppo rigida tra funzioni visive per la percezione e per l'azione, le dissociazioni percezione-azione non sono degli artefatti metodologici ma un problema teorico autentico. Sembra plausibile che in questi due sistemi ci siano diverse rappresentazioni spaziali ma anche delle connessioni non previste dal modello TVSH.

Full textVisual information is fundamental to interact with objects. For instance, information is coded by the visual system to create internal representations used to guide actions such as grasping, an action we perform efficiently daily many times. However, how the motor system codes object features for grasping remains poorly understood. In particular, a long-standing debate in the cognitive neurosciences concerns the nature of internal representations of object size during motor preparation, a key aspect of grasping. According to the most influential functional interpretation of the primate visual system, size representations are coded in critically different ways in the dorsal and ventral streams. These key differences in turn have several behavioural consequences, including a relative immunity of the dorsal representations of size from stimulus-contextual effects such as those observed for consciously perceived size. Accordingly, the goal of this thesis is to contribute to the understanding of representations for visually-guided actions by collecting data from psychophysical, kinematics, and EEG paradigms. I conducted four experiments assessing motor and perceptual responses to the Uznadze illusion. In this illusion, the same ‘test’ object appears larger (or smaller) after having seen a smaller (or larger) ‘inducing’ object. Studies 1 and 2 investigated whether size representations in action and perception are affected by this form of size contrast. In Study 1, participants either grasped a test or provided a perceptual judgment of its size (by performing a cross-modal match called a “manual estimation”) after the presentation of an inducer that could be identical, smaller, or larger. Results revealed that finger apertures in both motor and perceptual responses showed a size contrast effect, that is, were affected by the inducer size. In Study 2, two further manipulations of the Uznadze illusion were investigated. Inducers were presented either haptically or visually, and either in the same or in a different position relative to the test. Surprisingly, results revealed that motor responses show size contrast (the Uznadze illusion), or size assimilation (the inverse Uznadze illusion), or even no illusion, depending on factors that seem related to multisensory integration and the body schema rather than a perception-action distinction. Overall, Studies 1 and 2 provide evidence that size representations for action are affected by contextual information. Studies 3 and 4 investigated the time course of motor representations in the dorsal stream. We focussed on the time needed to prepare a grasp, testing whether motor preparation is affected by viewing a previous distractor object equal or different in size. Study 3 showed that participants were slower in preparing the grasp when distractors were larger than the test, but not when they were smaller. Study 4 extended this finding to event-related potentials (ERPs) recordings. Here, cortical indices of motor preparation to grasp the test were investigated after presenting distractors equal or different in size. Results revealed that components of lateralized readiness potentials (LRPs) were displaced in time consistent with the pattern of preparation times observed in Study 3 and 4. Taken together, Studies 3 and 4 show that grasping is not programmed solely from online information, but can be affected by information experienced recently. I conclude that the Uznadze temporal size contrast reveals that visuomotor preparation relies on relative spatiotemporal information comparable to that used to produce perceptual judgments. This conclusion challenges current theoretical models of the functional properties of the dorsal stream, suggesting a more nuanced view of factors affecting grasping and seeming behavioural perception-action dissociations.

Full textA large variety of sensory input from the world and the body, are continuously integrated in the brain in order to create supra-modal and coherent mental representations of our own body. Plasticity is a fundamental characteristic of the nervous systems, allowing constant adaptive changes in mental functions and behaviour. Thanks to this, even body representations can change according to experience and, crucially, they can be temporarily altered by means of experimental protocols. In the present work, we were interested in assessing the plasticity of the subjective metric of the body, and the effect of temporary changes in it on the processing of corporeal and spatial information. To this aim, two types of bodily illusion were used, i.e. the Mirror Box Illusion (MB) and the Full-Body Illusion (FBI), due to their known effects inducing strong modulations of body representation. The core mechanism accounting for the efficacy of these experimental procedures is likely to be the process of embodiment of an alien body part. In experiment 1 we used a visuotactile FBI-like paradigm to assess the feasibility and the replicability of the FBI for bodies of different sizes. Using this paradigm, we confirmed that it is possible to induce and replicate in the same participant, the embodiment towards mannequins of standard or bigger sizes. In experiment 2 and 3 we investigated body metric representation of the leg, and whether it can be plastically modulated by embodying mannequins of different sizes. To address this issue, we measured the effect of FBI induced by different body sizes, over a Body Distance Task (BDT), i.e. the assessment of the perceived distance between two touches applied to the participant’s leg. We found that the subjective experience of embodiment is also accompanied by a change in the perception of body metric that goes hand-in-hand with the current size of the embodied legs. Since we confirmed that, in healthy subjects, the metric representation of the body can be modulated, we addressed a similar question in patients with hemiplegia. In experiment 4, using a body bisection task we first observed that hemiparetic post-stroke patients show a proximal bias in the metric representation of their affected upper limb. Critically, we found that this bias shifts distally, towards the objective midpoint after a MB training session, compared to a control training without the mirror. In Experiment 5 we found a similar modulation of subjective body metric in a group of patients suffering from Ideomotor Apraxia, treated with a modified version of the MB setup, which was accompanied by an improvement in the programming of motor plans. In experiments 6 and 7 we focused more on the relationship between body metric and space representations. First, we tested the hypothesis that an altered body representation could modify the way in which individuals estimate their body affordances during a Motor Imagery Task. Our results showed that participants imagined walking faster after having been exposed to an illusion of longer legs. Furthermore, we found that the illusory embodiment of longer legs can affect the estimation of allocentric distances in extra-personal space. The embodiment of longer legs, on the one hand, reduced the perceived distance in meters, on the other hand, produced an enhancement of the number of steps that participants imagined they would have needed to walk between the same landmarks. In conclusion, we confirmed that it is possible to induce provisional modifications of the metric representation of the body, by means of body illusions. We showed that body representation is malleable to the point to shape our ability to estimate distances in the external world both in terms of reachability and allocentric distance estimation. Such plasticity of body representation and body-space interaction gives important clues for the understanding of body representation and its rehabilitation in neurological patients.

Full textThe present work focuses on disorders of the body image and is based on the clinical study of psychosis with special reference to a particular syndrome, first identified by the french school of psychiatry in 1927 and known as the fregoli delusion syndrome. Part 1 examines the genealogy of the fregoli syndrome and the way it was discovered in connection with the capgras syndrome. An outline of the main epistemological aspects of the discovery. Part 2 recalls the discussion of the fregoli syndrome in the field of psychiatry, including an analysis of the series it seems to fit in with quite naturally and which also includes the capgras syndrome and the syndrome of intermetamorphosis. Part 3 examines the neurological contribution to major clinical issues that can be assigned to the fregoli syndrome, especially as far as the disjunction between name and body image is concerned. Part 4 deals with the contribution of psychoanalysis to the above mentioned clinical issues, with an emphasis on the work of jacques lacan which allows us to underline their unity from a theoretical point of view. Lacan's formula, which he writes i(a), shows the image of the body, i, as based on the repression of an object, a, which the image both conceals and clothes. In the case of the fregoli syndrome, the formula will be split asunder, with the image on the one side, and the object on the other, but always with the same name for the patient. The final section deals with a structural analysis of the fregoli syndrome which makes it possible to caracterize with a remarkably small number of items: 1) the clinical varieties shown by the delusional misidentification syndromes; and 2) a wide range of identification and recognition psychopathological disorders. Appended, the full princeps observation of the fregoli syndrome by courbon and fail, and two clinical observations

Full textThe aim of this thesis is to show that a theory of perception cannot easily renounce to the concept of illusion without loosing a part of its explanatory power. The proposed characterization of the notion of illusion is based on some characteristics of the perceptual experience with illusory phenomena: the existence of a violation of coherence which alerts the subject to the presence of an error, the robustness of the illusory experience and the presence of a reaction of surprise. The description of a special group of illusory perceptual phenomena that are characterized by those three elements provides. The studies on perception with an instrument for acquiring an insight on perceptual mechanisms. The notion of illusion hence presents a heuristic value also in relationship to views of perception (e. G. The ecological and sensorimotor approaches) that criticize the classical characterization of the notion of illusion
