考虑了几种解释反应时间（RT）数据可能混淆视觉搜索率与非搜索相关因素差异的方式。为了确定不同年龄群体的搜索率估计值是否存在这个问题，我们将RT方法提供的估计值与使用有限时间刺激的强制选择方法获得的估计值进行了比较。强制选择方法提供了更快的搜索率估计。年龄（我们感兴趣的变量）的影响具有可比性，但使用两种方法获得的结果之间的差异表明，在使用RT方法时需要谨慎。在适当的情况下，如何使用强制选择方法来提供s是否执行串行搜索的独立测试，如果是，甚至从仅使用单个数组大小获得的数据中提供搜索率估计。（PsycINFO数据库记录(c) 2016 APA，版权所有）
Considered several ways in which the interpretation of reaction time (RT) data might confound differences in visual search rates with non-search-related factors. To determine whether estimates of search rates for groups differing in age suffered this problem, estimates provided by the RT method with those obtained using a forced-choice method with limited-duration stimuli were compared. The forced-choice method provided faster estimates of search rates. The effects of age, the variable of interest, were comparable, but the difference between results obtained using the 2 methods suggests the need for caution in using the RT method. How the forced-choice method can be used, under appropriate circumstances, to provide an independent test of whether Ss are carrying out serial searchers and, if they are, to provide search rate estimates even from data obtained using only a single array size is discussed.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
