Повний текст джерелаIn social species, animals must detect, evaluate and respond to the states of other individuals in their group. A constellation of gestures, vocalizations, and chemosignals enable animals to convey affect and arousal to others in nuanced, multisensory ways. Observers integrate such social information with environmental cues and internal physiology to general social behavioral responses via a process called social decision-making. The mechanisms and anatomical correlates of social decision-making, particularly those that allow behavioral responses to others’ emotional states, are not fully known. Therefore, the objective of this dissertation is to broaden the anatomical understanding of social decision-making by investigating the role of the insular cortex in social behaviors that depend upon others’ emotional state. Using a novel behavioral paradigm, I present causal evidence that implicates the insular cortex and its projections to the nucleus accumbens in social affective behavior. These findings are consistent with evidence from the literature that suggests insular cortex is positioned to convey sensory cues to social brain structures to produce flexible and appropriate behavioral responses to social affective cues

Повний текст джерелаLes expériences de stress psychologique constituent d'importants déterminants de la santé physique et mentale ; ainsi, un intérêt central de la recherché actuelle vise l'élucidation des relations entre la santé et le stress. Un système physiologique particulier fait l'objet d'un examen approfondi en ce qu'il serait fondamental à cette relation complexe, l'axe-hypotalamo-hypophyso-surrénalien. Bien qu'étant un système central de stress, la réponse de l'axe HHS varie considérablement parmi les individus. Les dernières décennies de recherche démontrent que certains facteurs individuels contribuent aux différentes réponses de stress et aux questions de santé. L'étude de ces facteurs devient conséquemment cruciale à notre compréhension des mécanismes sous-jacents liants les expériences du stress à la santé. Un facteur important, sinon majeur, influençant fortement la réponse de stress via l'axe HHS réside dans le fait d'être de sexe féminin ou masculin. Afin de poursuivre l'élucidation de ces différences de sexe quant à la réponse de stress, le travail présenté dans cette thèse vise l'éclaircissement des interactions entre les facteurs biologiques et situationnels d'un stress expérimental. Ainsi, l'effet des phases du cycle menstruel et une variation des genres au sein d'un comité d'évaluation ont été proposés pour l'étude du stress psychosocial. Les résultats nous révèlent que ces différences dans les réponses de stress entre les femmes et les hommes sont influencées par la variation des hormones sexuelles et le genre du comité d'évaluation. La considération de l'importance des phases du cycle menstruel de la réponse de stress des femmes nous a fait poursuivre, dans une seconde étude, notre questionnement concernant son effet sur l'association entre les réponses physiologiques et affectives du stress. Suite à un stress d'ordre psychosocial, les résultats pointent vers un effet significatif des phases du cycle menstruel sur l'association entre la réponse affective de stress et la réponse endocrine du stress (cortisol). À notre connaissance, il s'agit de la première démonstration de l'effet modulateur du cycle menstruel sur l'association entre les réponses affectives et endocrines du stress. Dans notre dernière étude, nous avons étudié les effets des phases du cycle menstruel sur les réponses physiologiques, affectives et neurales durant un stress psychosocial. Confirmant les résultats de la seconde étude, ils incluent à présent les aspects neuronaux de la réponse de stress, démontrant que les phases du cycle menstruel influence significativement l'association entre les aspects physiologiques et neuronaux du stress psychosocial. Cette thèse se termine par une discussion quant à la pertinence de ces résultats pour notre compréhension des réponses de stress psychosocial chez la femme et l'homme, ainsi que des hypothèses explicatives de l'association différentielle entre les aspects affectifs et physiologiques de la réponse de stress durant les phases du cycle menstruel. Les limites de la présente étude accompagnées de recherches futures sont aussi indiquées.

Social learning is a crucial component of human intelligence, allowing us to rapidly adapt to new scenarios, learn new tasks, and communicate knowledge that can be built on by others. This dissertation argues that the ability of artificial intelligence to learn, adapt, and generalize to new environments can be enhanced by mechanisms that allow for social learning. I propose several novel deep- and reinforcement-learning methods that improve the social and affective capabilities of artificial intelligence (AI), through social learning both from humans and from other AI agents. First, I show how AI agents can learn from the causal influence of their actions on other agents, leading to enhanced coordination and communication in multi-agent reinforcement learning. Second, I investigate learning socially from humans, using non-verbal and implicit affective signals such as facial expressions and sentiment.
This ability to optimize for human satisfaction through sensing implicit social cues can enhance human-AI interaction, and guide AI systems to take actions aligned with human preferences. Learning from human interaction with reinforcement learning, however, may require dealing with sparse, off-policy data, without the ability to explore online in the environment - a situation that is inherent to safety-critical, real-world systems that must be tested before being deployed. I present several techniques that enable learning effectively in this challenging setting. Experiments deploying these models to interact with humans reveal that learning from implicit, affective signals is more effective than relying on humans to provide manual labels of their preferences, a task that is cumbersome and time-consuming. However, learning from humans' affective cues requires recognizing them first.
In the third part of this thesis, I present several machine learning methods for automatically interpreting human data and recognizing affective and social signals such as stress, happiness, and conversational rapport. I show that personalizing such models using multi-task learning achieves large performance gains in predicting highly individualistic outcomes like human happiness. Together, these techniques create a framework for building socially and emotionally intelligent AI agents that can flexibly learn from each other and from humans.

Повний текст джерелаLong-term, but not subacute administrations of selective 5-HT reuptake inhibitors (SSRIs) attenuate the spontaneous firing activity of locus coeruleus (LC) NA neurons. On the other hand, subacute and sustained treatment regimens with NA reuptake inhibitors (NRIs) induce a robust and sustained decrease on NA firing without altering that of 5-HT. Interestingly, sustained SSRI and NRI treatments both abolished 5-HT1A receptor augmentations of LC firing, but left inhibitory 5-HT2A receptor responses normal or slightly desensitized. The SSRI induced dampening on LC firing is reversed by 5-HT2A receptors blockade. Thus, an overactivation of 5-HT 2A receptors during chronic SSRI administration results from desensitization of 5-HT1A receptors in the presence of 5-HT transporter reuptake inhibition.
Antagonism of 5-HT1A receptors attenuates LC NA firing, but is completely reversed by 5-HT2A receptors blockade. 5,7-DHT experiments indicate that these receptors in the LC are postsynaptic to 5-HT neurons, but the 5-HT1A effects are dependent on intact 5-HT neurons. This served as the impetus to a proposed neuronal circuitry detailing the mechanism by which these 5-HT receptors, and SSRI induce adaptations thereof, alter the NA system. This complex circuitry implicates other neurotransmitters being supported further by iontophoretic data demonstrating 5-HT1A receptor effects involve alterations in glutamate and 5-HT to mediate 5-HT2A receptor activation and regulate GABA release in the LC.
Given the abovementioned results, it was striking that a subacute treatment with YM992 (SSRI and 5-HT2A antagonist) attenuated NA firing to a similar extent as reported with NRIs. This was concluded to be due to overactivation of presynaptic alpha2-adrenoceptors. In contrast to NRIs, a 21-day treatment with YM992 desensitized this receptor subtype and is responsible for normalization of LC firing.
Reboxetine produces similar effects on 5-HT and NA neuron firing and reuptake blockade on CA3 pyramidal neurons in the hippocampus as the TCA desipramine. Unlike desipramine, reboxetine is able to alter 5-HT reuptake function and 5-HT2A receptors mediated responses by DOI after a prolonged administration and did not induce a sensitization of hippocampal 5-HT1A receptors. Thus, for the first time, experimental evidence supports that this latter effect is due to TCA structure and not NA reuptake blockade.
These results are extrapolated to the beneficial and side effects produced by antidepressants with hopes of expanding upon the former while reducing the latter in the treatment of anxiety and affective disorders.

Rouault, Marion. "Integration of beliefs and affective values in human decision-making." Thesis, Paris, Ecole normale supérieure, 2015. http://www.theses.fr/2015ENSU0052/document.
Повний текст джерелаExecutive control relates to the human ability to monitor and flexibly adapt behavior in relation to internal mental states. Specifically, executive control relies on evaluating action outcomes for adjusting subsequent action. Actions can be reinforced or devaluated given affective value of outcomes, notably in basal ganglia and medial prefrontal cortex. Additionally, outcomes convey information to adapt behavior in relation to internal beliefs, involving prefrontal cortex. Accordingly, action outcomes convey two major types of value signals: (1) Affective values, representing the valuation of action outcomes given subjective preferences and stemming from reinforcement learning; (2) Belief values about how actions map onto outcome contingencies and relating to Bayesian inference. However, how these two signals contribute to decision remains unclear, and previous experimental paradigms confounded them. In this PhD thesis, we investigated whether their dissociation is behaviorally and neurally relevant. We present several behavioral experiments dissociating these two signals, in the form of probabilistic reversal-learning tasks involving stochastic and changing reward structures. We built a model establishing the functional and computational foundations of such dissociation. It combined two parallel systems: reinforcement learning, modulating affective values, and Bayesian inference, monitoring beliefs. The model accounted for behavior better than many other alternative models. We then investigated whether beliefs and affective values have distinct neural bases using fMRI. BOLD signal was regressed against choice-dependent and choice-independent beliefs and affective values. Ventromedial prefrontal cortex (VMPFC) and midcingulate cortex (MCC) activity correlated with both choice-dependent variables. However, we found a double-dissociation regarding choice-independent variables, with VMPFC encoding choice-independent beliefs, whereas MCC encoded choice-independent affective values. Additionally, activity in lateral prefrontal cortex (LPFC) increased when decision values (i.e. mixture of beliefs and affective values) got closer to each other and action selection became more difficult. These results suggest that before decision, VMPFC and MCC separately encode beliefs and affective values respectively. LPFC combines both signals to decide, then feeds back choice information to these medial regions, presumably for updating these value signals according to action outcomes. These results provide new insight into the neural mechanisms of decision-making in prefrontal cortex

Повний текст джерелаThesis advisor: Hiram Brownell
Human voice carries precious information about a person. From a brief vocalization to a spoken sentence, listeners rapidly form perceptual judgments of transient affective states such as happiness, as well as perceptual judgments of the more stable social traits such as trustworthiness. In social interactions, sometimes it is not just what we say – but how we say it – that matters. This dissertation sought to better understand how affective properties in voice influence memory and how they subserve social perception. To these ends, I investigated the effect of affective prosody on memory for speech by manipulating both prosody valence and semantic valence, I explored the fundamental dimensions of social perception from voice, and I discussed the relationship of those social dimensions to affective dimensions of voice. In the first chapter, I examined how prosody valence influences memory for speech that varied in semantic valence. Participants listened to narratives spoken in neutral, positive, and negative prosody and recalled as much as they could of the narrative content. Importantly, the arousal level of the affective prosody was controlled across the different prosody valence conditions. Results showed that prosody valence influenced memory for speech content and the effect depended on the relationship between prosody valence and semantic valence. Specifically, congruence between prosody and semantic valence influenced memory. When people were listening to neutral content, affective prosody (either positive or negative) impaired memory. When listening to positive or negative content, incongruent prosody led to better recall. The present research shows that it is not just what you say, but also how you say it that will influence what people remember of your message. In the second chapter, I explored the fundamental dimensions of social perception from voices compared to faces, using a data-driven approach. Participants were encouraged to freely write down anything that came to mind about the voice they heard or the face they saw. Descriptors were classified into categories and the most frequently occurred social trait categories were selected. A separate group of participants rated the voices and faces on the selected social traits. Principal component analyses revealed that female voices were evaluated mostly on three dimensions: attractiveness, trustworthiness, and dominance; whereas male voices were evaluated mostly on two dimensions: social engagement and trustworthiness. For social evaluation of faces, a similar two-dimensional structure of social engagement and trustworthiness was found for both genders. The gender difference in social perception of voice is discussed with respect to gender stereotypes and the role voice pitch played in perceived attractiveness and dominance. This study indicates that both modality (voice vs. face) and gender impact the fundamental dimensions of social perception. Overall, the findings of this dissertation indicate that the affective quality in our voice not only influence how our speech will be remembered but also relate to how we are being socially perceived by others. It would be wise to pay more attention to our tone of voice if we want to make our speech memorable and leave a good impression

Повний текст джерелаWhile a number of studies have explored the functional neuroanatomy of social anxiety disorder (SAD), comparatively few studies have investigated the structural underpinnings in SAD. 18 psychopharmacologically and psychotherapeutically naïve adult patients with a primary Axis I diagnosis of generalized social anxiety disorder and 18 demographically (age, gender and education) matched healthy controls underwent 3T structural magnetic resonance imaging. A manual tracing protocol was specifically developed to compute the volume of the most prominent subcortical gray matter structures implicated in SAD by previous functional research. Cortical thickness was estimated using an automated algorithm and whole brain analyses of white matter structure were performed using FSL's tract - based spatial statistics comparing fractional anisotropy (FA), mean diffusivity (MD) in individuals with SAD. Manual tracing demonstrated that compared to controls, SAD patients showed an enlarged right globus pallidus. Cortical thickness analyses demonstrated significant cortical thinning in the left isthmus of the cingulate gyrus, the left temporal pole, and the left superior temporal gyrus. Analyses of white matter tractographic data demonstrated reduced FA in in the genu, splenium and tapetum of the corpus callosum. Additionally reduced FA was noticed in the fornix and the right cingulum. Reduced FA was also noted in bilateral corticospinal tracts and the right corona radiata. The results demonstrate structural alterations in limbic circuitry as well as involvement of the basal glanglia and their cortical projections and input pathways.

Повний текст джерелаBackground: Social anxiety disorder (SAD) is a common psychiatric condition characterised by fear and avoidance of social situations. Lifetime prevalence is 5-16% and co-morbidity with other mood and substance abuse disorders is common. Symptoms including cognitive, behavioural and physiological components vary between individuals. Of these, blushing and gaze fear and avoidance are regarded as cardinal symptoms. First line treatment of SAD involves SSRIs and cognitive behavioural therapy, while surgery may also be considered for excessive blushing. Blushing and gaze avoidance are thought to have an evolutionary adaptive advantage, promoting the display of submissive behaviour and appeasement in threatening situations. MRI research has demonstrated differences on functional and structural neuroimaging between patients with SAD and healthy controls (HCs). However, little is known about the neurocircuitry underlying gaze fear and avoidance or increased blushing propensity or how the severity of these traits correlate with the neuroimaging differences found in SAD. In this research, I explored the neuroanatomy of blushing propensity and gaze fear and avoidance in the context of SAD. Methods: 18 SAD patients and 18 HCs underwent structural MRI scans and self-report scales were administered to assess their symptom severity, blushing propensity and gaze fear and avoidance. Structural data was analysed using voxel-based morphometry (VBM). Regression and contrast analyses were used to correlate blushing propensity and gaze anxiety and avoidance symptoms with brain volumes, controlling for total grey matter volume, age and level of education. Results: Anxiety, blushing propensity and gaze fear and avoidance symptoms were all significantly higher in SAD patients (p<0.001). Brainstem volumes were increased for higher blushing scores a (p<0.01), while the volumes of left inferior parietal lobe b (p=0.04) and left occipital cortex a (p<0.01) were decreased. With increased gaze fear and avoidance, there were associated decreases in the right posterior cingulate cortex a (p<0.01), right occipital lobe b (p=0.03) and right fusiform gyrus a (p<0.01). Increased blushing and gaze symptom severity considered together, was associated with increased brainstem volume a (p<0.01) and decreased pons/cerebellum b (p=0.001), right cerebellum b (p=0.009), left cerebellum c (p<0.001) and left inferior parietal lobe a (p<0.1), volumes. Contrast analysis of SAD and HC brain volumes revealed a greater grey matter volume in HCs in the regions of left occipital cortex (p<0.01), left anterior cingulate (p<0.01) and right inferior parietal lobe (p<0.01) when compared to SAD patients. Increased symptom severity in SAD was significantly associated with higher volumes in the left premotor cortex (p<0.01), right hippocampus (p<0.01), left orbitofrontal cortex (p<0.01) and right superior temporal cortex (p<0.01). Possible areas for of interest for volume differences between SAD and HCs include total grey matter volume (d =0.83), left and right anterior cingulate cortex (d =0.68 and d =0.65), and left and right dorsolateral prefrontal cortex (d =0.55 and d =0.54), yet these differences were not significantly different. (a uncorrected peak levels b uncorrected cluster level, c corrected cluster level). Conclusion: Differences in brain volumes pertaining to blushing and gaze fear and avoidance in SAD patients may be a contributing factor or a consequence of these core symptoms, and a potential biomarker for SAD. Future studies could build on this preliminary research with increased sample sizes, and determine the possible effects of reduced symptom severity and treatment options on brain structure and function. Most importantly, an investigation of the genetic underpinnings and functional neural correlates of blushing and gaze avoidance behaviour may enhance our understanding of the complex aetiology of these cardinal SAD symptoms, thereby improving our understanding of SAD as a psychiatric disorder and facilitating better patient care and management.

Повний текст джерелаLes oiseaux chanteurs utilisent des signaux vocaux pour la communication sociale. Le chant peut être produit dans divers contexts sociaux et des etudes anterieures one démontré que la structure et l'organisation du chant variant considérablement selon les contexts sociaux. Cependant, nous savons peu de choses sur les circuits neuronaux et les neurotransmetteurs qui contribuent à la modulation sociale du chant. Nous combinons ici des experiences comportementales, immunocytochimiques et pharmacologiques afin de découvrir les mécanismes qui sous-tendent les changements contextuels åa la structure et à l'enchaînement des syllabes chez les dominos. Dans l'ensemble du circuit qui sous-tend le contrôle moteur vocal, nous avons découvert que l'expression du gène précoce immédiat EGR-1 était plus importante lorsque les oiseaux chantaient seuls que lorsqu'ils chantaient dans un contexte de pariade. Un examen de l'expression du gène EGR-1 dans les neurones producteurs de catécholamine donne à penser que les catécholamines jouent un rôle dans la modulation sociale du chant. Pour vérifier cette idée, nous avons analysé l'effet de l'amphétamine sur l'organisation du chant et nous avons découvert que l'amphétamine reproduisait les effets du contexte social sur la structure des syllabes, mais qu'elle n'avait aucun effet sur l'enchaînement des syllabes. Ces données appuient la notion selon laquelle la modulation sociale de l'activité neuronale dans le système de chant sous-tend les changements contextuels dans le chant et que les catécholamines, comme la dopamine, contribuent à la modulation sociale du comportement vocal.

Повний текст джерелаThis dissertation addressed three central goals using a mixed-methods approach: The first goal was to develop a comprehensive model of affective-motivational research dispositions for students of the social sciences since existing models of research competence concentrate on cognitive dispositions. With the help of expert interviews and an expert rating, nine affective-motivational research dispositions were identified. The second goal was the development and validation of test instruments to assess the identified affective-motivational research dispositions. Based on the standards of psychological test construction, self-assessment scales were developed for all nine affective-motivational research dispositions and evidence for their validity was generated. These previous steps formed the basis for addressing the third goal: To test whether research-based learning is a suitable format to foster different cognitive and affective-motivational research dispositions in the social sciences. Research-based learning is a didactic format in which students complete a full research cycle to answer a research question. So far, there are many theoretical claims on the effectiveness of research-based learning in the social sciences but a lack of empirical evidence. In a pre-post study (N=952) in research-based learning courses, it was shown that students benefit from a favourable development of some of the research dispositions, whereas other dispositions decreased. The role of the facilitating instructor proved to be central.

Повний текст джерелаSeveral functions have been attributed to dreaming. Existing literature reviews on the theories of the function of dreaming are not exhaustive and contain few criticisms. The introduction of this thesis fills this gap in the literature by offering a critical review of contemporary theories of the function of dreaming. In light of this introduction, all existing theories present important limitations. The first chapter of this thesis is an article presenting a new theory of the function of dreaming: the Feeling Priming Theory (FTP). According to the FPT, the function of dreaming is to favor the motivation to avoid aversive anticipated events and to approach gratifying anticipated events. More specifically, it is suggested that a component of anticipated emotions – anticipated feelings – is reproduced in dreams. Upon awakening and during the day, these anticipated feelings would remain (pre)activated (primed) in memory. Consequently, anticipated emotions would exert a greater influence on avoidance and approach behaviors, mainly through an increase in the intensity of anticipatory feelings (i.e., feelings of fear or hope/desire). The second chapter of this thesis is an article presenting the development and use of a protocol aimed at testing hypotheses from the FPT. Sixty-four participants completed a logbook at home for a period that included two days with dream recall. Data were collected after waking up, after the morning routine, and before the bedtime routine. Participants reported their anticipated events, their degree of fear, desire and control over the anticipated events, the behaviors and decisions they adopted in relation to the anticipated events, the extent to which they thought about the anticipated events, and the similarity between their anticipated feelings and their dream feelings. The hypotheses were tested using linear and binary logistic mixed models. Fear toward an aversive anticipated event positively predicts the probability that the negative anticipated feeling associated with this anticipated event be reproduced in a dream. Experiencing this negative feeling in a dream positively predicts fear toward the aversive anticipated event on the next day, which in turn positively predicts the occurrence of an avoidance behavior. Furthermore, desire toward a gratifying anticipated event positively predicts the probability that the positive anticipated feeling associated with this anticipated event be reproduced in a dream. However, experiencing this positive feeling in a dream does not predict desire toward the gratifying anticipated event on the next day. Overall, the results from the validation study support part of the FPT. The conclusion of this thesis reviews the strengths and limitations of the proposed theory and the validation study. In the light of these strengths and limitations, potential avenues of research are explored. It is suggested that the FPT could serve as a basis for the development of a cognitive theory of dream production. Moreover, the empirical study could be replicated in a laboratory setting, which would allow to test the FPT in a controlled environment. Finally, the possibility of developing a new psychological treatment for nightmares based on the FPT is discussed. In summary, this thesis constitutes a major contribution to the dream literature. It presents a critical review of contemporary theories of the function of dreaming, proposes the FPT as an alternative to emotion regulation theories of dreaming, reports the results of an empirical study aimed at testing several hypotheses from the FPT, and demonstrates the relevance of this work for future theoretical, empirical, and clinical research.

Повний текст джерелаDespite the great interest addressed to the topic of emotions, it has always been treated as a marginal issue if compared to cognition. Nonetheless in the last 30 years a new perspective suggested that emotions are effectively the causes, mediators, or consequences of other psychological processes, and, above all, of interpersonal relations. The first study of the present Doctoral Thesis was conceived as an emotion induction paradigm in the attempt to identify some biological markers of the subjective emotional experience within a multi-method perspective. Then, in the attempt to move a step forward in describing the social dimension of the emotional sharing, the second study was designed by creating emotional stimuli that represented real interactions between two inter-agents. They could also vary for phylogenetic closeness following the hypothesis that, thanks to mirroring and simulation processes, emotion perception is easier when the other agent is perceived as similar. Finally, the idea that some variables related to the social encounter are able to modulate the capacity to resonate with others’ emotions was better explored in the last study: a real social cooperative task in the form of a hyperscanning paradigm. The aim was to explore the presence of synchronized patterns during the joint action. To conclude, the three studies have been designed according to an increased level of complexity, from a single-subject perspective towards a two-person approach, with simple, interactive, and dynamic emotional cues during simple, complex, and hyper-complex emotional contexts.
