Recent behavioral, neuroimaging, and neurophysiological research suggests a common representational code mediating the observation and execution of actions; yet, the nature of this representational code is not well understood. The authors address this question by investigating (a) whether this observation-execution matching system (or mirror system) codes both the constituent movements of an ac...

OBJECTIVES Individuals' perceptions of their own age(ing) are important correlates of well-being and health. The goals of the present study were to (a) examine indicators of self-perceptions of aging across adulthood and (b) experimentally test whether age stereotypes influence self-perceptions of aging. METHOD Adults 18-92 years of age were presented with positive, negative, or no age stereo...

Four experiments explored the interrelations between working memory, attention, and eye movements. Observers had to identify a tilted line amongst vertical distractors. Each line was surrounded by a colored shape that could be precued by a matching item held in memory. Relative to a neutral baseline, in which no shapes matched the memory item, search was more efficient when the memory cue match...

Cortical activity is thought to reflect the biomechanical properties of movement (e.g., force or velocity of movement), but fatigue and movement familiarity are important factors that require additional consideration in electrophysiological research. The purpose of this within-group quantitative electroencephalogram (EEG) investigation was to examine changes in cortical activity amplitude and l...

Purpose: to prove a technique of the improvement of special physical fitness due to the development of coordination abilities at a stage of the previous basic preparation. Material and Methods: theoretical analysis and synthesis of data of scientifically methodical literature and empirical materials of the scientific research, pedagogical methods of the research, tool methods: program of diagno...

There is recent evidence that we directly map observed actions of other agents onto our own motor repertoire, referred to as direct matching (Iacoboni et al., 1999). This was shown when we are actively engaged in joint action with others' (Sebanz et al. 2003) and also when observing irrelevant movements while executing congruent or incongruent movements (Brass et al., 2000). However, an open qu...

Does real time coupling between mental and physical activity early in development have functional significance? To address this question, we examined the habituation of visual attention and the subsequent response to change in two groups of 3-month-olds with different patterns of movement-attention coupling. In suppressors, the typical decrease in body movement at the onset of looks persists in...

This thesis explores some of the social factors that may affect individuals as they age. A lifespan developmental perspective is employed in investigating the effects of societal aging stereotypes on will-to-live and risk-taking skills. Results suggest negative aging stereotypes may have deleterious effects on the elderly, but not young individuals in terms of will-to-live, but have no effect o...

Stereotypes from the major nationality toward minorities constitute a widely concerning problem in many countries. As reported by previous studies, stereotypes can be activated by media information that portrays the negative aspects of the target group. The current study focused on the neural basis of the modulation of negative media information on Han Chinese stereotypes toward Uyghurs by usin...
