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 利用实验室研究 与任务无关的意象和思想（TUIT）， 老年人比年轻人和中年人有更少的TUIT。 一 对这一结果的可能解释是，年龄和浓度 能力直接相关。 需要实验室调查 为了证实这种明显增加的集中能力， 老年人口。 开发了一种实验程序， 受试者被要求重复呈现给一只耳朵的信息 （阴影）而忽略另一只耳朵中的同时消息。 通过等效跟踪证明了该算法具有很强的集中能力 有和没有同时（和不同）消息的性能 另一只耳朵。 一项使用年轻人（18-29岁）的实验研究， 中年（40-55岁）和老年（65-85岁）受试者完成。 在控制了智力，听力损失， 和单声道遮蔽性能，确定年龄和 注意力集中的能力是负相关的。 随年龄增加 双耳两分阴影误差增加。 减少 随着年龄的增长，集中能力也很明显， 样本仅限于那些没有服用处方药人 药物治疗，并且在过去两年内没有住院， 当样本仅限于那些没有单声道的人时， shadowing错误

A primary purpose of this work is to investigate the relationship between age and concentrative ability. Using laboratory studies of task-unrelated imagery and thought (TUIT) it was determined that old adults had fewer TUITs than young and middle-aged adults. One possible explanation for this result is that age and concentrative ability are directly related. 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. High 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 yrs), middle-aged (40-55 yrs) and old (65-85 yrs) subjects was completed. After controlling for differences in intelligence, hearing loss, and monaural shadowing performance it was determined that age and concentrative ability are inversely related. With increased age there was an increase in dichotic shadowing errors. The decrease in concentrative ability with increased age was also evident when the sample was restricted to those who did not take prescription medication and were not hospitalized within the prior two years and when the sample was restricted to those who made no monaural shadowing errors.
