AGE EFFECTS ON CONCENTRATION DURING INFORMATION PROCESSING

这项工作的主要目的是调查两者之间的关系 在年龄和注意力能力之间。利用实验室研究 与任务无关的图像和思想(Tuit)的结果是 老年人的TUIT比年轻人和中年人要少。一 这一结果的可能解释是年龄和专注力 能力是直接相关的。需要进行实验室调查 为了证实这一明显增强的注意力集中能力 人口老龄化。开发了一种实验程序，其中 受试者被要求复述呈现给一只耳朵的信息 (跟踪)同时忽略另一只耳朵中的同步消息。 高度集中的能力通过等同的影子表现出来。 在同时(和不同)消息的情况下的性能 在另一只耳朵里。使用杨氏(18-29岁)的实验研究， 研究对象为中年(40~55岁)和老年(65~85岁)。 在控制了智力差异、听力损失后， 和单声道的影子表演，确定了年龄和 注意力集中的能力是负相关的。随着年龄的增长 二分阴影错误有所增加。减产 随着年龄的增长，注意力集中的能力也很明显 样本仅限于没有服用处方药的人 服药且在前两年内未住院且 当样本被限制在那些没有制造单声道的人 隐藏错误。

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.
