视觉搜索中的年龄差异：目标学习和干扰学习。
作者：

研究了语义类别视觉搜索任务中的年龄差异，以确定年龄效应是否源于目标学习缺陷、分心学习缺陷或两者的组合。12名年轻人(平均年龄20岁)和12名老年人(平均年龄70岁)分别在一致和不同版本的搜索任务中接受了2400次试验。在训练之后，一系列的转移-反转操作允许单独和结合地评估目标学习和分心学习。数据模式表明，老年人在增加目标的注意力吸引强度和减少分心事物的注意力吸引强度方面存在缺陷。根据基于强度的视觉搜索性能框架对结果进行解释。
Age differences in a semantic category visual search task were investigated to determine whether the age effects were due to target learning deficits, distractor learning deficits, or a combination thereof. Twelve young (mean age 20) and 12 older (mean age 70) adults received 2,400 trials each in consistent and varied versions of the search task. Following training, a series of transfer-reversal manipulations allowed the assessment of target learning and distractor learning both in isolation and in combination. The pattern of data suggests that older adults have a deficit in their ability to increase the attention-attraction strength of targets and to decrease the attention-attraction strength of distractors. The results are interpreted in terms of a strength-based framework of visual search performance.
