Study title

This dataset contains data of N = 221 participants, that took part in a repeated testing study of cognitive ability tests. Participants were aged 18-77 of various backgrounnds, although the majority were university students. All tests were administered in German. The cognitive ability tests used were the Short Form of the Berlin-Intelligence-Structure Test (BIS-S), a recently developed figural matrices test (HeiQ), and three working memory capacity tasks (Running Span Task, Operation Span Task, and the Symmetry Span Task). All tests were administered in person three times over three test sessions that lasted three hours each. Test sessions were about 10-12 weeks apart. For every test session, cognitive ability tests and their order were held constant. Additionally, psychological questionnaires of interest were administered. Similar to the cognitive ability tasks, the Big-Five-Inventory (BFI-2XS for session one and two and BFI-2 for session three), the Need-For-Cognition (Short Scale), the General Self-Efficacy (GSE) Scale, the Multidimensional Mood Questionnaire (MDMQ) Short Form, two subscales (worry and emotionality) of the Test Anxiety Inventory, and Test Familiarity were administered on all three test sessions. On test session two and three, participants were asked whether they used any test taking strategies (open reply format). For data protective reasons, demographic variables cannot be shared. The purpose of the study was to further previous research on the retest effect for cognitive ability tests in a) investigating individual differences and b) taking a facet approach for cognitive ability facets instead of investigating general intelligence.
