AGE EFFECTS ON CONCENTRATION DURING INFORMATION PROCESSING

这项工作的主要目的是调查的关系， 年龄和专注力之间的关系 采用回顾性 Giambra的调查问卷显示，老年人，特别是 男性，报告较少分心，较少走神， 无聊 需要实验室调查来证实这一点 老年人的注意力明显增强。 开发了一种实验程序， 要求重复呈现给一只耳朵的消息（阴影）， 忽略另一只耳朵同时收到的信息。 更大 通过等价跟踪证明了算法的集中能力 有无同时（和不同）的性能 另一只耳朵里的留言 一项实验研究使用年轻的 开始对18-29岁、40-55岁和65-85岁的老年人进行研究。 初步结果支持更集中的概念， 能力，在阴影中，与老科目相比， 年轻的实验对象。 下一个财政年度的工作将包括：（a）继续 本研究的数据收集，直到有30名受试者， （B）调查各年龄组之间的关系， 跟踪任务的难度、年龄和注意力集中程度。

A primary purpose of this work is to investigate the relationship between age and concentrative ability. Using a retrospective questionnaire Giambra has shown that older individuals, especially men, reported less distractibility, less mindwandering, and less boredom. Laboratory investigations are needed to confirm this apparent increased concentrative ability in the older population. An experimental procedure was developed where subjects are asked to repeat messages presented to one ear (shadowing) while ignoring simultaneous messages in the other ear. Greater concentrative ability is demonstrated by equivalent shadowing performance with and without simultaneous (and different) messages in the other ear. An experimental study using young (18-29), middle-aged (40-55) and old (65-85) subjects was begun. Preliminary results support the notion of greater concentrative ability, during shadowing, with the old subjects when compared with the young subjects. Efforts over the next fiscal year will include: (a) continuation of the present study's data collection until there are 30 subjects in each age group and (b) an investigation of the relationship among the difficulty of the shadowing task, age, and concentrative level.
