| Abstract [eng] |
The purpose of this study is to explore the factorial structure of information processing speed and to analyze how information processing speed along with memory and mental set-shifting are related to age, mental illness, also demographic, health and psychosocial variables. 556 adults (M age = 33.60, SD = 12.86, range: 18-65) participated in the research. The results of the research show that information processing speed among adults is best explained by structure of two factors: simple IPS and complex IPS. This information processing speed structure is invariant across mental illness and control samples and age groups. Cognitive abilities were predicted by age, mental illness, demographic, health and psychosocial variables. Age and mental illness relationships with cognitive abilities are mediated or moderated by demographic, health and psychosocial variables. Final model in which age, mental illness, also demographic, health and psychosocial variables directly and indirectly predict cognitive abilities separately fit the data better than a model where simple IPS is a global mediator. |
