Cognition and aging: a highly selective overview of event-related potential (ERP) data.
نویسنده
چکیده
An overview of highly selected cognitive aging investigations of deviance detection, episodic memory and working memory reveals two primary themes: (1) when variability in elderly samples has been assessed, it has proven useful in understanding age-related changes in cognition; and (2) there is a frontal lobe contribution to at least some age-related changes in cognition. However, there are too few ERP age-related investigations of individual differences to determine whether the changes in patterns of ERP responding can be deemed "compensatory" or "inefficient." It is suggested that, to the extent possible, future electrophysiological investigations of cognitive aging (as well as other physiological measurement techniques) include individual difference measures that will enable the determination of the implication of a given neural pattern in the genesis of a given, age-related behavioral outcome pattern.

Introduction: One of the secondary consequences of burnout is a significant reduction in cognitive functions, the most obvious and important of which is the cognitive function of attention and control, which can play a vital role in efficiency and prevention of errors at work in many occupations. On the other hand, a neurological examination is needed to understand better the relationship betwe...

Background: Self-esteem, the value we place on ourselves, has been associated with effects on health, and life satisfaction. Many studies reported that children with attention-deficit/hyperactivity disorder (ADHD) suffer from low self-esteem has been associated with negative life outcomes. The present study investigated neural correlation of self-esteem in this group compared with typically dev...

Introduction: Emotional stimulus is processed automatically in a bottom-up way or can be processed voluntarily in a top-down way. Imaging studies have indicated that bottom-up and top-down processing are mediated through different neural systems. However, temporal differentiation of top-down versus bottom-up processing of facial emotional expressions has remained to be clarified. The present st...
متن کاملProtective role of educational level on episodic memory aging: an event-related potential study.
The aim of the present experiment was to investigate whether educational level could modulate the effect of aging on episodic memory and on the electrophysiological correlates of retrieval success. Participants were divided into four groups based on age (young vs. older) and educational level (high vs. low), with 14 participants in each group. Event-related potentials (ERP) were recorded while ...

The DRM paradigm is used to examine false memory—when a list of highly associated words (e.g. SEWING, THREAD, THIMBLE) is studied, a nonpresented but associated false target (e.g. NEEDLE) is often confidently (but incorrectly) identified as having been studied. An ERP study was conducted with a sample of young and older adults to examine age differences in false memory and neurological distinct...
