Electrocortical and behavioral responses of low, moderate, and high physically active older adults were compared with a younger control group on neutral and incompatible conditions of a flankers task. Compared to younger adults, high and moderate active older adults exhibited increased event-related potentials component P3 amplitude for the incompatible condition at the frontal electrode site. For the neutral condition, only low active older adults exhibited decreased amplitude at the central-parietal site, compared to younger adults. P3 latency revealed the longest latencies for low active older adults, followed by moderate active, high active, and younger adults, respectively. Reaction time (RT) data revealed that younger adults exhibited faster RT compared to all three older groups. Results suggest that physical activity may improve executive control function in older adults by affecting the distribution of P3 amplitude, which has been related to memory and attentional processes, and by decreasing P3 latency, which relates to the speed of cognitive processing. 相似文献

This study describes how meaning potentials were constructed in the literacy event known as Morning Message. Morning Message provided teachers and students with opportunities to construct a written text around the experiences of one student. This discourse of writing allowed for the examination of how meaning was orchestrated and scaffolded between the teacher and her students. Three findings are discussed, including the function of a series of conversational involvement moves utilized by the teacher, the specific writing conventions and metamessages afforded in the Morning Message dialogue, and an examination of how the social dialogues of Morning Message may have come to guide independent action as internalized processes on several transfer measures. 相似文献
