Achtsamkeit wird mit vielen positiven Effekten für das psychische Wohlbefinden assoziiert, wobei Fähigkeiten wie Emotionsregulation (ER) und soziale Kognition (SC) zu den wichtigsten Mechanismen gehören. In der vorliegenden Doktorarbeit wurde die Beziehung zwischen Achtsamkeit, ER und SC mit verschiedenen methodischen Ansätzen untersucht. In Studie I wurde mithilfe von Literatur und empirischen Modellen die Beziehung zwischen Achtsamkeit und ER ausgearbeitet und verschiedene psychologische und neurokognitive Mechanismen diskutiert. Studie II zielte darauf ab den ER-Mechanismus bei „Trait-Achtsamkeit“ zu entschlüsseln. Hier zeigte sich, dass es sowohl bei Probanden mit einer Borderline-Persönlichkeitsstörung als auch bei gesunden Teilnehmern einen mediierenden Effekt von Selbstmitgefühl gab, der Achtsamkeit mit ER-Merkmalen verband. Studie III untersuchte den Zusammenhang zwischen ER und SC mit Hilfe von Verhaltens- und Neuroimaging-Experimenten, mit Fokus auf dem Konzept der sozialen ER (die Fähigkeit, die Emotionen anderer zu modulieren). Es zeigte sich, dass bei der Regulierung der Emotionen anderer der eigene Stress reduziert wird, wobei wichtige "soziokognitive" Hirnregionen (z.B. Precuneus) an der Vermittlung dieser Effekte beteiligt sind. Studie IV untersuchte im Rahmen einer Neuroimaging-basierten randomisierten Kontrollstudie ER-Mechanismen während einer achtsamkeitsbasierten Intervention (MBI). Die Studie zeigte eine durch die MBI induzierte ER-Verhaltensplastizität im Gehirn, sowohl für die Eigen- als auch für die soziale ER. Ein Effekt im Vergleich zu SC (kognitive und emotionale Empathie) wurde nicht gezeigt. Unter Einbezug aller Ergebnisse wurde ein Modell postuliert, das den Austausch und die Regulierung von Emotionen im Kontext von sozialen Interaktionen integriert. Die Dissertation bietet neue Einblicke in die ER-Mechanismen der Achtsamkeit und beleuchtet die individuellen Determinanten sozialer Prozesse durch das Zusammenbringen von ER und SC. / Mindfulness, the capacity to fully attend to the present experience, has been linked to a myriad of mental health benefits, being abilities such as emotion regulation (ER) and social cognition (SC) of the main potential active mechanisms. The current doctorate thesis investigated the relationship between mindfulness and ER and SC using a range of methodological approaches from trait level individual differences to behavioral and brain mechanisms. Study one explored the relationship between mindfulness and ER by examining the diverse literature and empirical models, discussing different psychological and neuro-cognitive mechanisms. Study two intended to unravel the ER mechanism of trait mindfulness, showing in both borderline personality and healthy subjects the mediating effect of self-compassion linking mindfulness and ER traits. Study three further investigated the link between ER and SC using behavioral and neuro-imaging experiments, addressing the notion of social ER (the capacity to modulate others’ emotions). It showed that when regulating others’ emotions, an individual’s own distress is reduced, being key ‘sociocognitive’ brain regions (i.e. precuneus) engaged in mediating these effects. Study four investigated the fine-grained ER mechanisms of a mindfulness-based intervention (MBI), comparing the MBI with a reading group (READ), in the context of a neuroimaging-based randomized controlled trial. This study revealed ER brain behavioral plasticity induced by the MBI, for both self and social ER. It also showed a lack of effect over SC (cognitive and emotional empathy). Articulating overall findings, a model that integrates exchanges and regulation of emotions in the context of social interactions is proposed. The dissertation offers new insights into mindfulness’ ER mechanisms, from dispositions to neuro-behavioral levels, and also sheds light onto individual level determinants of social processes, linking ER and SC.

L’homme est un animal social. La majorité des décisions que nous prenons se font dans un contexte social et dépendent d’autrui, ce qui implique des calculs cérébraux complexes qui incluent tous les facteurs contextuels et environnementaux. La majorité des études ultérieures de la prise en compte d’autrui dans la décision ont utilisé des tâches de partage de récompenses entre soi et autrui. Les choix possibles amènent le décideur à considérer autrui, mais dans le but de gagner soi-même une récompense ; donc dans un contexte où les récompenses liées à soi et les récompenses liées à autrui sont confondues. Le travail présenté dans cette thèse avait pour but une meilleure compréhension des mécanismes cérébraux soutenant l’intégration d’autrui dans la prise de décision, sans que la récompense pour autrui n’interfère directement avec soi. Nous nous sommes appuyés sur le cadre théorique de la décision perceptuelle et des modèles de diffusion pour l'étude i) des modifications du processus décisionnel induites par une récompense monétaire allant à autrui et ii) de l’impact de l’effet d’audience (le fait de se sentir observé) sur la décision. Nos résultats computationnels montrent qu'une récompense pour autrui, par rapport à une récompense pour soi, et une audience, par rapport au secret, modifient le taux de dérive de la variable de décision. En magnétoencéphalographie, nos résultats indiquent que les décisions pour soi et pour autrui diffèrent pendant, mais aussi après, la prise de décision dans des zones cérébrales associées avec la transformation sensori-motrice, l'ajustement du compromis entre rapidité et justesse et avec la cognition sociale. Ainsi, le cortex temporal montre des différences de -1170 millisecondes (ms) à -1023 ms, de -993 ms à -915 ms et de -343 ms à -188 ms en amont de la réponse. Ce qui suppose une influence sur l’intégration des preuves sensorielles. Après la décision, les régions frontales ont également montré des différences entre soi et autrui, de 153 ms à 303 ms post-réponse, suggérant une différence entre soi et autrui dans l’ajustement du compris entre justesse et rapidité. Le bénéficiaire de la récompense associée à la décision modifie les paramètres décisionnels et les corrélats cérébraux de la décision perceptuelle, démontrant l’importance du contexte social dans l’implémentation de la prise de décision chez l’Homme. Ce travail appuie également l’utilité des modèles mathématiques tels que les modèles de diffusion dans la compréhension des processus décisionnels, même de ceux découlant de la cognition sociale / Humans are inherently social: most of human’s decisions are within a social context and depend on others. For more than a century, researchers explore aspects of social cognition. Aiming to understand human behavior in social contexts, neuro-economic researches showed that taking others into account involve complex brain computations that include all environmental and contextual factors. However, most of the work was made using money allocation tasks; mixing self-affecting and other-affecting rewards into the decision making process. The present work intended the understanding of the brain mechanisms underpinning the integration of others into the decision making process for decisions that include others and do not interfere with self-rewards.Taking advantage of mathematical models from the drift diffusion models framework, we conducted experiments investigating how others influence the mechanistic of perceptual decisions and their correlates in the human brain. We showed that taking rewards for others into account and being observed by others influence the drift rate of the decision variable. The drift rate is higher in audience than in secret and higher for self-rewards than for other-rewards. These results indicate that others are integrated into the accumulation process together with the evidence available for making a decision. At the brain level, we found difference between self and other decisions over the anterior temporal and centro-frontal cortices during decision making. This suggests that the beneficiary of a decision modifies sensory-motor transformation processes. In addition, self- and other-affecting difference showed difference over the medial frontal sensors after the decision making process, indicating a variation in the speed-accuracy tradeoff adjustment process

The purpose of the present study was to explore a theoretically based social-cognitive model of posttraumatic stress disorder (PTSD) by investigating attachment-related and social-cognitive predictors of PTSD in a sample of 125 post-9/11 U.S. combat veterans. Subjects completed an online survey assessing PTSD symptomology, attachment-related internal working models, perceived social support, and mentalizing capacity. Path analysis provided empirical support for a respecified version of the model. More negative internal working model of self and poorer mentalizing capacity predicted higher PTSD symptom levels. Contrary to previous findings, greater perceived social support predicted higher, not lower, PTSD symptom levels. Mentalizing capacity mediated the relationship between internal working model of self and PTSD symptoms in a complementary manner, whereas perceived social support as a mediator was dampening. The relationship between internal working model of others and PTSD symptom levels was fully mediated by perceived social support, which buffered the effect of negative working model of others on PTSD symptom levels. These findings underscore the importance of social-cognitive processing, rooted in early attachment experiences, in the development and symptomology of PTSD in trauma-exposed veterans. In preparing clients for trauma work, clinicians may consider employing modalities that promote earned secure attachment and highlight mentalization in the therapeutic change process.

Affinity 2.5 is a computer-based instrument designed to measure sexual interest using viewing time of images depicting fully-clothed males and females of different ages. Participants are asked to rate the sexual attractiveness of the person in the image according to a 15-point scale while their viewing time of each image is surreptitiously monitored. The validity of viewing time as a measure of sexual interest is based on social cognition theory and is established in the review of literature. The number of images comprising Affinity 2.5 represents a 42.9% increase from the previous version of the assessment, Affinity 2.0. The purpose of this study was to examine the temporal stability of scores on Affinity 2.5 for a sample of exclusively heterosexual, nonpedophilic males and females. Viewing time data from 63 males and 84 females were analyzed using a chi-square procedure. Results of this analysis indicate that 86% of responses from the male participants and 88% of responses from the female participants were consistent from time one to time two. As suspected, these percentages represent an increase in reliability over the temporal stability of the shorter Affinity 2.0.

Negative attitudes towards atheists are hardly a new trend in our society. However, given the pervasiveness of the prejudices and the lack of foundation for them, it seems warranted to explore the underlying elements of these attitudes. Identifying these constitutive elements may help pick apart the different contributing factors and perhaps mitigate or at least understand them in the future. The present study was designed to identify which myths or stereotypes about atheists are most influential in these attitudes. A Lexical Decision Task was utilized to identify which words related to popular stereotypes are most related to the label atheists. The labels Atheists, Christians, and Students were compared to positive words, negatives words, words or interests, neutral words, and non-word strings. Analyses revealed no significant differences among the participants' reaction times in these various comparisons, regardless of religion, level of belief in god, level of spirituality, or being acquainted with atheists. Possible explanations for these results are discussed in this thesis.

The objective of the research was to investigate an improvement in job performance when role-play is used as a training and assessment tool in a sales call centre environment. The research was conducted by means of a competence assessment used at different stages (Quality Assurance Performance Management Questionnaire). The final stage was two weeks after the learners who had qualified to be sales agents had entered a real working environment. At this final stage, calls were retrieved and rated against the Quality Assurance Performance Management Questionnaire (QAPMQ). A sample of 40 novice sales agents (learners) were selected and randomly divided into the control and experimental groups. The research findings indicated that if planned well, role-play can be an effective training and assessment tool. / Industrial & Organisational Psychology / M.Comm.

The theories of social cognition and personal constructs compose the theoretical backdrop to this dissertation which deals with people's expectations regarding romantic partners and relationships.Five women were interviewed and a qualitative analysis undertaken and discussed with a view to elucidating the influence of one's parents, cultural background and individual identity on the development and functioning of expectations. These expectation are based on beliefs about men and relationships in general and about healthy and unhealthy relationships in particular. Attension is given to the role of relationship beliefs and expectations in evaluations of romantic relationships and the consequences of such evaluations for relationship satisfaction and commitment. It is concluded that expectations play an important role in the process of partner and relationship eva,uation and thus, in the outcome of relationships. Parental and cultural influences are found to play an important part in shaping individual values and expetations, albeit in an indirect manner. / Psychology / M.A. (Psychology)

The centralised control over curriculum framing and pedagogy, the generally poor quality of teaching with little sensitivity to children’s sociocultural environment; and very high drop out rates, even at the primary school level, are some of the challenges facing school education in many of the regions of India. However, one of the successful approaches to these challenges has been the Digantar school system, working in rural communities. The study is based in one Digantar School in Rajasthan and employs concepts derived from the Vygotskian tradition to interrogate the methods employed in Digantar school system. The study took Edwards’ (2010a, 2011, 2012) idea of common knowledge and Hedegaard’s (2008, 2012, 2013) idea of institutional demand in practices as conceptual lenses through which to investigate the components of the pedagogical practices that help Digantar teachers to align the motives of the school with those of the child in classroom activities. In doing so it analyses the institutional practices that lead to the development of common knowledge that in turn facilitates how teachers engage pupils as learners. Data were gathered over six months and comprised around 120 hours of school-based video data together with interviews and detailed observations with teachers and community members. Data were gathered in classrooms, teacher meetings, meetings between parents and teachers and at school-community meetings. Analyses focused on the construction of common knowledge and the use made of it by the school to achieve a mutual alignment of motives between the practices of the school with the community and the families. The study has revealed that teachers’ engagement with the knowledge and motives of other teachers and community members helped to create common knowledge, i.e. an understanding of what mattered for each participating group, which facilitated teaching-learning in the school. The analysis also points towards a form of democracy, which enhances children’s participation in their learning. It was found that building and sharing of common knowledge and creating a socially articulated ‘space of reasons’ (Derry 2008) produced a pedagogical model that engaged children in creating their social situation of development, seeking and recognising the curriculum demands being placed on them.
