Vitamin C plays a role in neuronal differentiation, maturation, myelin formation and modulation of the cholinergic, catecholinergic, and glutaminergic systems. This review evaluates the link between vitamin C status and cognitive performance, in both cognitively intact and impaired individuals. We searched the PUBMED, SCOPUS, SciSearch and the Cochrane Library from 1980 to January 2017, finding...

Few studies have examined the performance of the 15-item Geriatric Depression Scale (GDS-15) among older adults with cognitive impairment. The GDS-15 was administered to 166 cognitively impaired and 144 cognitively normal older volunteers. We compared the two groups on total score, individual item endorsement, and three factor scores: General Depressive Affect, Withdrawal, and Life Satisfaction...

Research consistently shows that groups composed of cognitively diverse individuals develop more effective approaches in solving complex problems, and generate more creative and innovative ideas relative to groups that are not cognitively diverse (Hoffman & Maier, 1961; Hong & Page, 2004; Page, 2007; Johnson, 2008). The concept of cognitive diversity is defined as the degree to which group memb...

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...

The first major part of this paper is a comprehensive cognitively-oriented analysis of the senses and their interrelations of the verb to run along the lines of much recent cognitive work on polysemy. In the second major part, all occurrences of to run from the ICE-GB and the Brown Corpus are coded for a variety of linguistic parameters (so-called ID tags), yielding a complete behavioral profil...

Software design is a cognitively challenging task. Most software design tools provide support for editing, viewing, storing, and transforming designs, but lack support for the essential and difficult cognitive tasks facing designers. These cognitive tasks include decision-making, decision ordering, and task-specific design understanding. This paper describes Argo/UML, an object-oriented design ...
