Whether you are trying to impress others, communicate efficiently, develop trust with your teammates or followers, or choose key partners to work with, you need to accurately anticipate what others think of you. This process, which is called meta-perception (Laing, Phillipson, & Lee, 1966), is thus crucial for your day-to-day life, and also at work. Still, meta-perception fails to be considered as a key individual process in the field of Organizational Behavior – OB. Therefore, this dissertation aims to gather empirical and theoretical evidence showing that meta-perception is an important process for organizational life. Thus, this dissertation focuses on the process itself (i.e. meta-perception and meta-accuracy), its antecedents and its outcomes, applied to social evaluation situations that are common at work. First, I aim to provide the bases of a consensual and context-specific approach of meta-perception enabling its study in the field of OB by differentiating the manifestations of meta-accuracy and by using statistical methods that consider both components of meta-accuracy, namely meta-perception and other-perception (Edwards, 1995, 2002; Shanock, Baran, Gentry, Pattison, & Heggestad, 2010). Second, I aim to examine whether meta-perception, its bias and its accuracy are affected by specific antecedents (i.e. narcissism and leadership style) that have received growing attention in OB. Third, I aim to study the effect of meta-perception and its accuracy on outcomes usually influenced by person perception, such as performance and hireability, and characterized by social evaluation. To achieve these aims, four research projects were performed (i.e. three empirical projects, gathering eight studies, and one theoretical project). The first project examines the link between narcissistic tendencies and a specific form of meta-perception. The second project tests the effect of leadership style on the accuracy of meta-perception and whether this accuracy has a positive impact on task performance. The third project provides a theoretical framework on the advantages of including meta-perception of performance in Multi-Source Feedback. The fourth project tests whether meta-perception and its accuracy play a role in hireability. These research projects led to key contributions to the literature on meta-perception and its accuracy, narcissism, leadership and the field of OB. First, this research contributes to the literature on meta-perception by proposing a context-specific approach of meta-perception. This dissertation specifically justifies the need to (a) differentiate the aspects on which meta-perception focuses (e.g. emotions, behaviors, skills, traits), (b) study meta-perception as related to self-perception and other-perception to gain knowledge about the bias and accuracy of meta-perception, and (c) examine the role of meta-accuracy in predicting organizational behaviors according to its three dimensions (i.e. size, direction, and favorability). Second, it contributes to the literature on leadership by studying the effect of narcissism and leadership style on meta-perception through the assessment individuals’ egocentrism and flexibility. Third, it contributes to the OB field and meta-accuracy literature by showing that the three dimensions of meta-accuracy (i.e. size, direction and favorability) have specific effects on task performance, professional development and hireability. In fine, this dissertation constitutes a well-documented plea for the integration and recognition of meta-perception as a key process in Organizational Behavior studies. / Doctorat en Sciences économiques et de gestion / info:eu-repo/semantics/nonPublished

This thesis presents a critical disability discourse analysis. It examines the discursive construction of disability and the personal and political positioning of disabled people. Focusing on disclosure, identity, activism, theory and policy issues relating to disabled people, the naturalisation and invalidation of the disabled body is explored and critiqued. Organised in three parts, the thesis begins by considering some significant historical moments, the sociolegal context and the recent politicisation of both disabled people and disability research. Disability is argued as embedded in, and institutionalised by, political regulatory structures and research that risks de-politicisation of it is critiqued. Part two considers theories, methods and the text data collected for the research. This defines the theoretical orientation to discursive psychology, discourse analysis and critical disability studies. Disability is articulated as an object in, and for interaction and its construction linked to historical, social and political structures that regulate and sustain the human subject. The text data used in the thesis is then presented in terms of the collection process and the organisation of extracts within the current thesis. The forms of text data collected include transcriptions of discussion groups with disabled people, front line workers and senior managers, policy documents, publicity imagery and Hansard records of parliamentary debates. Part three then presents a critical disability discourse analysis using this text data. Drawing on the framework of discourse analysis as articulated by Potter and Wetherell (1987) the discursive function, construction and variation of disability talk and textwork is critically considered. This reveals dilemmas of positioning and ideology during moments of disability disclosure. Analytical commentary argues that disability identity is constructed by an interpretative repertoire embedded in the antithesis of desired and valued life. The construction of ‘barriers’ in social model texts are also explored in discussion groups and local policy documents. This shows the recent distortion and colonisation of the social model, and suggests that the metaphor of ‘barriers’ used to signify the structures that disable people has lost its once radical and resistive power. Hansard records are then used to explore implications and dilemmas which arise regarding agency, autonomy and the disabled body in relation to dominant discourses of individualism and the challenges this poses for an ‘independent living’ reform strategy. The thesis concludes by asserting a discursive mode of disablism. This is suggested as a useful driver for research and initiatives to expose and challenge everyday discourses and practises that perpetuate the invalidation of the disabled body.

Social cognitive abilities are needed to process and understand social information in order to respond appropriately in everyday social interactions. While there are a number of tests that have been developed to measure social cognition in the literature, many have important limitations such as only assessing one ability, performance being predicted by measures of intelligence and exhibiting low ecological validity. To address some of these limitations, I developed a new test called the Edinburgh Social Cognition Test (ESCoT). The ESCoT is an animated test that assesses four domains of social cognition: cognitive Theory of Mind (ToM) (What is X thinking?); affective ToM (How does X feel at the end of the animation?); interpersonal understanding of social norms (Did X behave as other people should behave?); and intrapersonal understanding of social norms (Would you have acted the same as X in the animation?). The aims of this thesis were to examine the validity of the ESCoT as a test of social cognition and to further investigate social cognitive processes in healthy and neurological populations. The ESCoT was firstly administered to a healthy population of older, middle-aged and younger adults to examine the effects of ageing on social abilities. This study found that the ESCoT was sensitive to age; poorer performances on cognitive and affective ToM and also interpersonal but not intrapersonal understanding of social norms were predicted by older age. Furthermore unlike traditional tests used in the study, performance was not predicted by measures of intelligence. Instead, the sex of participants and autistic-like traits, in addition to age were found to be important for performance. The ESCoT was then validated in a sample of adults with Autism Spectrum Disorder (ASD), and performance was compared to performance on established social cognition tests. Convergent validity was demonstrated in the study and the ESCoT was sensitive to social cognitive difficulties found in ASD. This study also showed that the ESCoT was more effective than existing tests at differentiating ASD adults and neurotypical controls. The interplay of social anxiety and empathy on ESCoT performance in addition to further exploring sex and autistic-like traits were then examined in a younger adult population. Social anxiety and empathy were not significant predictors of performance on the ESCoT. Similar to the results of the ageing study, this study found that women were better than men on affective ToM. However, unlike the ageing study, better cognitive ToM performance was predicted by older age. Better performance on interpersonal understanding of social norms and ESCoT total scores were predicted by more years of education. The subsequent chapter then examined the clinical efficacy of the ESCoT in a patient population (Alzheimer's disease, behavioural-variant Frontotemporal dementia and amnestic mild cognitive impairment). Here performance on the ESCoT was compared between the patients and neurotypical controls. It was found that patients performed poorer than neurotypical controls on ESCoT total scores, affective ToM, inter-and intrapersonal understanding of social norms. The final chapter returned to healthy ageing to more closely investigate the consequences of healthy ageing on social cognitive processes, by examining the positivity bias (preference for positive over negative stimuli) found in older adults using an attention paradigm. There was no evidence of the positivity bias in older, middle-aged and younger adults in regards to reaction time or accuracy. However, older and middle-aged adults differed in accuracy across stimuli type compared to younger adults. This thesis offers novel insights into the social cognitive abilities of various populations. The ESCoT presents a new, informative and validated test of social cognition for researchers and clinicians to use, which has many advantages over established tests of social cognition.

Forced displacement is the crises of our time as it has reached an unprecedented magnitude and rate, which exceeds the capacity of the international relief system and required efforts from global citizens, institutions, governments and communities. Social psychology has an important role in this needed mass response, to provide a better understanding of how the forcibly displaced people deal with their situation and how they are affected by it. Taking into consideration the sharp gap of resources available to the international relief system, it is especially important to understand the natural mechanisms of support the affected communities have, which can be an effective tool to build more efficient interventions and to empower marginalised communities and individuals. This research project aims to explore one possible mechanism underlining social support among refugees of conflict in developing countries, and sought to answer three main questions: how refugees help each other? Does sharing an emergent identity of being a “refugee” facilitate support among them, similar to people affected by disasters? Does this shared identity-based support impact their health? After conducting a systematic literature review (Paper 1) of psychosocial support among refugees of conflict in developing countries, we identified that the main challenge was the stressors arising from the exile environment (secondary stressors) and found indications of shared identity-based support among them. To do further exploration with social identity in mind, we conducted an 8-month ethnography (Paper 2) with Syrian refugees in Jordan that revealed an emergent shared “refugee” identity which seems to stem from a sense of common fate and motivates providing help to other refugees in addition to creating new social networks in exile that facilitates support efficiently. To better understand the secondary stressors (Paper 3), we conducted a survey (N = 305) and combined it with ethnographic data to find that Syrian refugees in Jordan suffer the most from financial stressors, due to loss of income and high living expenses; environmental stressors arise from exile and are either circumstantial (e.g., services and legal requirements) or created by this environment (e.g., instability and lack of familiarity); social stressors, directly related to social relations (e.g., discrimination & exploitation). In order to explore the process of support and the exact role of shared identity, we conducted two surveys (Paper 4) among Syrian refugees in Jordan (N = 156) and Turkey (N = 234) and used path analysis to build a model, which suggested that shared social identity is an important predictor of providing support and collective efficacy, which in turn has a positive association with general health of the refugees. We found indications that such positive associations could have a buffering effect in counter to the negative effect of stressors and stress on the health of refugees. We do acknowledge the stigmatic nature of a “refugee” identity and that there are other sources of support among the refugees. Nevertheless, we suggest that shared social identity can be a valuable resource in the field of psychosocial support among refugees of conflict in developing countries, especially if incorporated in the design of community level intervention.

Markus and Kitayama (1991) developed self-construal theory, and proposed that independent and interdependent self-construals would account for cultural variations in cognition, emotion and motivation. Based on this theory and Vignoles and colleagues' (2016) reconsideration of self-construal measurement, this thesis investigates if a multi-dimensional model of self-construal helps explain cultural differences better than previous studies using the conventional two-dimensional model, as well as reporting the development of a scale that unpacks eight different ways of being independent and interdependent in multiple cultures. The thesis includes three studies. Focusing on the cultures of China and the UK, Study 1 explores if a seven-dimensional self-construal model (Vignoles et al., 2016) helps provide previously missing evidence for the predicted mediation effects of selfconstrual on cultural differences in cognition, emotion and motivation. The results show that Chinese and British participants are significantly different in six dimensions of self-construal, and explicit self-construal significantly mediated cultural differences in certain aspects of cognition, emotion and motivation. In the same two cultures, Study 2 examines individualism and collectivism priming techniques, using the seven-dimensional self-construal model to detect what two commonly used selfconstrual primes actually manipulate. The results indicate that Similarities vs. Differences with Family and Friends task (SDFF) and Sumerian Warrior Story (SWS) cue different aspects of self-construal. Effects of SWS show a similar profile across the two cultures, whereas SDFF has a much stronger effect on Chinese participants than British participants. Study 3 reports the development of a new self-construal scale. By introducing a new factor and extending the participants to 13 countries, the final version is a 48-item eight-dimensional self-construal scale. The importance of the multidimensional model and the new measure are discussed.

We can easily and reliably identify the gender of an unfamiliar interlocutor over the telephone. This is because our voice is “sexually dimorphic”: men typically speak with a lower fundamental frequency (F0 - lower pitch) and lower vocal tract resonances (ΔF – “deeper” timbre) than women. While the biological bases of these differences are well understood, and mostly down to size differences between men and women, very little is known about the extent to which we can play with these differences to accentuate or de-emphasise our perceived gender, masculinity and femininity in a range of social roles and contexts. The general aim of this thesis is to investigate the behavioural basis of gender expression in the human voice in both children and adults. More specifically, I hypothesise that, on top of the biologically determined sexual dimorphism, humans use a “gender code” consisting of vocal gestures (global F0 and ΔF adjustments) aimed at altering the gender attributes conveyed by their voice. In order to test this hypothesis, I first explore how acoustic variation of sexually dimorphic acoustic cues (F0 and ΔF) relates to physiological differences in pre-pubertal speakers (vocal tract length) and adult speakers (body height and salivary testosterone levels), and show that voice gender variation cannot be solely explained by static, biologically determined differences in vocal apparatus and body size of speakers. Subsequently, I show that both children and adult speakers can spontaneously modify their voice gender by lowering (raising) F0 and ΔF to masculinise (feminise) their voice, a key ability for the hypothesised control of voice gender. Finally, I investigate the interplay between voice gender expression and social context in relation to cultural stereotypes. I report that listeners spontaneously integrate stereotypical information in the auditory and visual domain to make stereotypical judgments about children's gender and that adult actors manipulate their gender expression in line with stereotypical gendered notions of homosexuality. Overall, this corpus of data supports the existence of a “gender code” in human nonverbal vocal communication. This “gender code” provides not only a methodological framework with which to empirically investigate variation in voice gender and its role in expressing gender identity, but also a unifying theoretical structure to understand the origins of such variation from both evolutionary and social perspectives.

Dehumanization is a process whereby people fail to view others as human beings. Instead, the others are perceived as nonhuman animals or objects, unworthy of the same moral treatment. Dehumanization has previously been studied in a variety of different scholarly domains without adhering to a uniform theoretical framework. This literature review contrasts research on fully humanized perception, with research on dehumanized perception, and proposes neural areas which are likely to be involved. Not every aspect of dehumanization can be understood at the neurological level. To understand what factors lead up to, and modulates dehumanization, other perspectives might also be necessary. Dehumanized perception is coupled with reduced activity in the social cognitive brain network, a wide network which encompasses several cortical and subcortical areas. This disengages prosocial abilities and allows for other people to be treated like objects and means to an end. One area of special interest is the medial prefrontal cortex (MPFC). It functions as an integration center in the person perception network and is also active when we make moral judgments, empathize, or take the perspective of someone else. For this reason, the MPFC is sometimes used as an index of dehumanized perception.

L’adaptation aux transitions psychosociales dépend essentiellement de la planification de ces phases. Cependant, de nombreux individus ne planifient pas, s’exposant à des troubles psychologiques post-transitionnels. Ce travail doctoral s’intéresse, par conséquent, aux mécanismes sous-tendant la planification des transitions psychosociales et tente ainsi d’expliquer les différences interindividuelles en termes de planification. Plus précisément, nous soutenons la thèse selon laquelle les variables dispositionnelles déterminent les processus explicatifs de la planification des transitions psychosociales. Bien que les traits de personnalité soient liés aux réactions et à l’adaptation aux transitions psychosociales, la littérature n’évalue pas ou peu le rôle de la personnalité dans les processus de planification. En se basant la Théorie du Comportement planifié (Ajzen, 1991), le modèle de Beehr (1986), la Théorie Sociocognitive des Carrières (Lent, Brown, & Hackett, 1994) et le modèle en cinq facteurs de la personnalité (Digman, 1990), ce travail a pour objectif d’identifier les variables dipositionnelles en tant que les facteurs explicatifs de la planification des transitions psychosociales. Il atteste que les variables sociocognitives contribuent à la planification de l’arrêt de la carrière sportive de haut niveau (étude 1). Les traits de personnalité influencent l’âge planifié de départ à la retraite professionnelle (étude 2). De plus, le Caractère Consciencieux contribue à la planification de la carrière professionnelle future des athlètes de haut niveau actifs (étude 3). Enfin, les traits de personnalité prédisent la planification de la carrière future parmi les étudiants de première année de Licence (étude 4). Ce projet permet donc de mettre en évidence la personnalité en tant que déterminant de la planification des transitions psychosociales et apporte, par conséquent, des éléments de compréhension des différences interindividuelles de planification des transitions psychosociales. Finalement, ce travail doctoral atteste de la nécessité d’individualiser la prise en charge afin de mieux préparer les individus en vue de la transition. / Post-transitional adaptation depends on transition planning. However, many people do not plan ahead, exposing themselves to psychological distress following the transition. Thus, this doctoral project thus focuses on mechanisms underlying transition planning and attempts to explain individual differences in terms of planning. More precisely, we support the thesis that dispositional variables determine the processes that explain transition planning. Although personality traits are linked to reactions and adaptation to transition, research evaluating the role of personality in transition planning is lacking. Based on the Theory of Planned Behavior (Ajzen, 1991), Beehr’model (1986), the Social Cognitive Career Theory (Lent, Brown, & Hackett, 1994) and the Five Factor Model (Digman, 1990), this doctoral project aims to identify personality factors explaining psychosocial transition planning. It demonstrates that sociocognitive variables contribute to retirement planning from elite sport (study 1). Personality traits influence the planned retirement age from work (study 2). In addition, conscientiousness contributes to career planning among elite athletes through career goals and self-efficacy (study 3). Finally, personality traits predict career planning amongst students (study 4). Overall, this project contributes to highlighting personality traits as determinants of sociocognitive mechanisms of transition planning and further provides a better understanding of processes underlying individual differences in psychosocial transition planning. Finally this doctoral project demonstrates the need to individualize support to better assist individuals in transition preparation.

There is increasing recognition that contextual aspects of social situations are important determinants of children's social information processing. While it is generally accepted that friends influence children's social behavior, the immediate influence of a friend in specific conflict situations is less understood. Contextualized vignettes depicting hypothetical peer conflict situations were developed to examine the impact of situational context, namely a friend's suggested attribution and an antagonist action cue, on students' social information processing. A repeated measures design examined the proximal influence of situational context on 4th and 5th grade students' (N=367) own intent attributions, emotional reactions, and response evaluations to hypothetical peer conflict scenarios. Results indicated that situational context is important to students' social cognition. Students adjusted their social cognition and emotion in response to cues to an antagonist's intent and were influenced by a friend's comments during peer conflict scenarios. Students' responses were more aligned with the antagonist's action than a friend's suggested attribution. However, a friends' attribution was influential in situations where it conflicted with the antagonist's action. Results of this study help to increase knowledge regarding the context of social cognition and can assist in the development of more ecologically valid social skill interventions.
