Background: Down syndrome (DS), the most common genetic cause of intellectual disability, is associated with an ultra-high risk of developing Alzheimer’s disease. However, there is individual variability in the onset of clinical dementia and in baseline cognitive abilities prior to decline, particularly in memory, executive functioning, and motor coordination. The LonDownS Consortium aims to de...

Researchers often treat workload as a task-dependent variable. To evaluate the effect of workload on individuals' performance, researchers commonly use several methods, such as varying the complexity or number of tasks that test participants are asked to handle or placing individuals under time constraints. Only rarely have researchers investigated workload as a variable dependent on individual...

This study further examines the failure of game form recognition in preference elicitation (Cason and Plott, 2014) by making more cognitively demanding through a cognitive load manipulation. We hypothesized that if subjects misperceive one for another game, then depleting their resources, would misconceive more-cognitively task less-cognitively at higher rate. find no evidence suffer from first...

We estimated the effect of human capital on leadership. Our human capital measures included not only the traditional measures of education and on-the-job learning but also measures of cognitive and noncognitive abilities. The measures of cognitive abilities included numeracy, literacy, and problem solving, and the noncognitive abilities measures included perseverance, openness to learning, and ...

This paper investigates the relation between cognitive abilities and behavior in strategic-form games with the help of a novel experiment. The design allows us first to measure the cognitive abilities of subjects without confound and then to evaluate their impact on behavior in strategic-from games. We find that subjects with better cognitive abilities show more sophisticated behavior and make ...

A total of 3,781 healthy adults between 18 and 97 years of age completed trait anxiety and depressive symptoms inventories and also performed a battery of cognitive tests. Consistent with recent research on cognitive abilities, the cognitive variables could be organized into a hierarchical structure, with 5 first-order abilities and a single g-factor representing the variance common to the firs...

It has long been proposed that cognitive aging in fluid abilities is driven by age-related declines of processing speed. Although study of between-person associations generally supports this view, accumulating longitudinal between-person and within-person evidence indicates less strong associations between speed and fluid cognitive performance. Initial evidence also suggests that cognitive flex...
