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

Action-äventyrspels immersion och användbarhet påverkas av deras UI:s form och design. Tidigare forskning visar att diegetiskt UI bidrar till immersion men forskningen saknar insikter om hur olika varianter av UI påverkar spelens användbarhet. Data insamlad från test av spelares upplevelse av immersion och användbarhet i tre olika artefakter – designade med icke-diegetiskt-,meta-perceptivt- och diegetiskt UI – visar att när diegesen ökar så ökar även immersionen, samtidigt som användbarheten sjunker. Eftersom studiens resultat är baserade på tre artefakter som bara använder sig av en variant av UI så visar den inte slutsatser om hur kombinationer av UI kan främja användbarhet och immersion, vilket uppmanar till framtida studier. Studiens resultat uppmanar också till framtida studier i andra genrer av spel.

Cette thèse porte sur une population d’adolescents ayant un diabète de type 1 et leurs parents. Elle examine l’influence de la perception du diabète de type 1 par les adolescents et par leurs parents sur leur ajustement respectif à la maladie. En premier lieu sont présentées les caractéristiques du diabète de type 1, ses spécificités à l’adolescence, et les deux critères retenus pour examiner l’ajustement à la maladie : le contrôle métabolique et la qualité de vie. Après avoir défini la notion de perception de la maladie et décrit ses influences sur l’ajustement, le rôle de la perception des proches est examiné. L’étude de la perception de la maladie dans la famille en auto- et en hétéro-évaluation est ensuite proposée. Les deux axes de recherche envisagés visent à mettre en évidence l’existence d’une potentielle interprétation de la perception des proches et à en analyser l’influence sur l’ajustement à la maladie. Les deux premières études mettent en évidence l’impact de la perception du diabète en auto- et en hétéro-évaluation, par les adolescents et leurs parents, sur leur ajustement. La dernière étude permet de rendre compte, par une approche qualitative, des liens entre la perception de la maladie dans la famille et la qualité de vie des adolescents, au regard de la gestion familiale du diabète. En conclusion, nous soutenons l’intérêt de l’étude de la perception de la maladie dans la famille par le prisme de la perception interpersonnelle et de la méta-perception. Les limites de ce travail, les pistes de recherche et les perspectives d’application sont finalement discutées. / This thesis focuses on a population of adolescents with type 1 diabetes and their parents. It examines the influence of adolescents’ and their parents’ perceptions of type 1 diabetes, on their respective adjustments to the disease. First, we present the characteristics of type 1 diabetes, its specificities in adolescence, and two criteria used to examine adjustment to the disease : metabolic control and quality of life. After having defined the notion of illness perception and describing its influences on adjustment, the role of family members' perception is examined. A study of illness perception in the family through self- and hetero-evaluation is then presented. The two lines of research aim to highlight the existence of potential interpretations of the family members’ perceptions and analyze their influence on adjustment to the illness. The first two studies highlight the impact of type 1 diabetes' perception, both self- and hetero-evaluation, by adolescents and their parents on their adjustment. The last study reports, using a qualitative approach, the links between illness perception in the family and adolescents' quality of life, in light of family diabetes management. In conclusion, our studies provide further support the need to study the illness perception in the family through the prism of interpersonal perception and meta-perception. Finally, the limits of this work and research and applied perspectives are discussed.
