Individual Differences in Susceptibility to Investment Fraud

Individual differences in cognitive flexibility.

I s it better to be flexible, or persistent? A colleague once said that the secret to success in science is perseveration (no, not mere perseverence—that wouldn’t get you very far at all). Yet we all believe that the highest levels of cognitive function are associated with extreme flexibility—the ability to juggle many things at once and not get hung up on just one. Indeed, this ability to jugg...

Individual differences in cognitive arithmetic.

Unities in the processes involved in solving arithmetic problems of varying operations have been suggested by studies that have used both factor-analytic and information-processing methods. We designed the present study to investigate the convergence of mental processes assessed by paper-and-pencil measures defining the Numerical Facility factor and component processes for cognitive arithmetic ...

Different Task Complexity Factors and Cognitive Individual ‎Differences: The Effects on EFL Writers’ Performance

This study aimed at examining the main and interaction effects of increased intentional reasoning demands, planning time, and also language learning aptitude on syntactic complexity, accuracy, lexical complexity, and fluency (CALF) of 226 EFL learners’ performance on letter writing tasks. The participants were first randomly assigned to three experimental groups to be given a task with differin...

Emotion, working memory task demands and individual differences predict behavior, cognitive effort and negative affect.

We examined whether positive and negative affect motivates verbal and spatial working memory processes, respectively, which have implications for the expenditure of mental effort. We argue that when emotion promotes cognitive tendencies that are goal incompatible with task demands, greater cognitive effort is required to perform well. We sought to investigate whether this increase in cognitive ...
