A thesis is an aptitude test for students. The approval of the thesis is proof that the student has sufficient research and reporting skills to graduate but does not guarantee the quality of the research and the results of the research as such, and the thesis is therefore not necessarily suitable to be used as an academic source to refer to. If you would like to know more about the research discussed in this thesis and any publications based on it, to which you could refer, please contact the supervisor mentioned.
Abstract
Social feedback is inherent to the trait of cognitive insight. This trait, comprising selfreflectiveness and self-certainty, can be described as the ability to evaluate one’s own interpretations by incorporating social feedback, and, if necessary, to reappraise these. Cognitive insight has been found to be poorer for individuals diagnosed with schizophrenia. Treatment protocols aimed at improving this trait may elevate the prognosis for affected individuals. Using dynamic functional connectivity (dFC), this study aimed to investigate networks underlying cognitive insight, to help the development of such treatment protocols. Participants (n = 58) completed a cognitive insight questionnaire and a social feedback processing fMRI task, including self- and other-related feedback. Three hypotheses were investigated, as we expected 1) distinct dynamic connectivity states for self- vs other-related feedback processing, 2) that higher self-certainty correlates with higher occurrence of a state comprising the reward system, and 3) that higher self-reflectiveness correlates to higher occurrence of a state comprising the mentalizing system. Highest differences in dFC states were found when connectivity across individuals was represented in 12 distinct brain states. State 11, a network that includes occipitoparietal regions, was activated more often during the self-condition compared to the other condition. No significant correlations between occurrence of brain states and self-certainty nor self-reflectiveness were found.
