Changing cognitive performance in human elderly users requires a real-time assessment of current performance to provide appropriate, i.e. adaptive, assistance without bothering them. In the presented approach, the assessment of cognitive performance is done by simulating the user’s cognitive functions through a computational cognitive model that is highly individualized for the specific user. T...

neuropsychological studies have demonstrated that preclinical dementia accompanies a decreasing trend in cognitive state a few years prior to clinical diagnosis. sudden decline in episodic memory and semantic knowledge have been found to have the capability to differentiate patients in preclinical state of dementia from those experiencing normal aging. in addition, decline in episodic memory is...

introduction: age-related decreases in cognitive functions such as executive functions are a common phenomenon. cognitive rehabilitation with two main approaches, compensation and remediation, is used to help elderlies coping with these deficits. despite reported benefits, there are doubts on the efficacy of each of these approaches. we tried to provide effective computerized cognitive tasks as...

background: patients with parkinson's disease (pd) have different cognitive impairments.the goal of this study is the analysis of these changes in the mentioned patients.a cross-sectional study was performed on 87 patients with pd. patients were given a questionnaire to gather data about their medical and living statuses. to assess cognitive assessment, scopa-cog (scales for outcome in parkinso...

The Montreal Cognitive Assessment (MoCA) is a brief cognitive instrument for screening milder forms of cognitive impairment. The present study aimed to analyze the influence of sociodemographic (age, gender, educational level, marital and employment status, geographic region, geographic localization, and residence area) and health variables (subjective memory complaints of the participant and e...

OBJECTIVES This study investigated how interindividual differences in cognitive function are related to interindividual differences in the motivational trait of need for cognition, cognitive activity levels, and depressive symptomatology in a sample of young-old adults. METHOD The ample comprised 333 recent retirees from the Concordia Longitudinal Retirement Project (mean age = 59.06 years at...

Purpose: To sharpen the concepts of tacit, implicit and explicit knowledge by linking them to findings from cognitive psychology and memory science and thus finding a possibility for measuring non-explicit knowledge. Methodology/Approach: A review of KM and cognitive science literature leads to a dimensional model of knowledge types that links the concepts from KM to more specific concepts from...

BACKGROUND Clock drawing is part of the Montreal Cognitive Assessment (MoCA) test but may have administration and scoring limitations. We assessed (1) the reliability of the MoCA clock criteria relative to a published error scoring approach, (2) whether command-only administration could distinguish dementia from cognitively intact individuals and (3) the value of adding a clock copy condition t...

The genetic influences on aging-related phenotypes, including cognition and depression, have been well confirmed in the Western populations. We performed the first twin-based analysis on cognitive performance, memory and depression status in middle-aged and elderly Chinese twins, representing the world's largest and most rapidly aging population. The sample consisted of 384 twin pairs with a me...
