On the basis of attention allocation models of time estimation, the role of working memory in prospective duration reproduction is explored. In four experiments, adult participants performed a counting task (duration, 400 sec) that allowed coordinative and sequential demands on working memory to be varied. After completing the counting task, the(More)
Substantial evidence suggests that test anxiety is associated with poor performance in complex tasks. Based on the differentiation of coordinative and sequential demands on working memory (Mayr & Kliegl, 1993), two studies examined the effects of sequential demands on the relationship between test anxiety and cognitive performance. Both studies found that(More)
The executive function of shifting between mental sets demands cognitive flexibility. Based on evidence that physical exercise fostered cognition, we tested whether acute physical exercise can improve shifting in an unselected sample of adolescents. Genetic polymorphisms were analyzed to gain more insight into possibly contributing neurophysiological(More)
Research on effects of acute physical exercise on performance in a concurrent cognitive task has generated equivocal evidence. Processing efficiency theory predicts that concurrent physical exercise can increase resource requirements for sustaining cognitive performance even when the level of performance is unaffected. This hypothesis was tested in a(More)
We investigated how the updating of spatial situation models during narrative comprehension depends on the interaction of cognitive abilities and text characteristics. Participants with low verbal and visuospatial abilities and participants with high abilities read narratives in which the protagonist's motions in a fictitious building were either highly(More)
The paper highlights the importance of looking at individual differences in working memory in order to understand complex social perceptual processes such as the construction of mental clique models from pairwise sentiment relations. We found that working memory resources constituted a limiting factor in the integra-tive perception of sentiment patterns(More)
The crossover effect (Mani & Johnson-Laird, 1982) predicts that a mental model is more likely to be available after reading a determinate description of a spatial scene than after reading an indeterminate description whereas the reverse should apply to the propositional text representation. Although attempts to replicate this pattern were less than(More)
