大学生 (n= 24) 的 2 次反应时间 (RT) 实验中的刺激质量和刺激概率各不相同。在实验 I 中，Ss 在具有固定设置程序的 Sternberg 范例中运行，并且通过改变刺激与其背景之间的对比度来操纵刺激质量。刺激概率和刺激质量都会影响 RT，并且这两个变量的交互作用非常显着。在实验 II 中，刺激的概率和质量与实验 I 中一样有所不同，但 S 的任务是为刺激命名。同样，刺激概率和质量影响 RT，尽管这两种影响都小于实验 I。刺激概率和质量的相互作用也很显着。两个实验的结果都表明刺激概率影响刺激编码阶段；这被解释为反对最近记忆扫描过程的自我终止搜索模型的证据。（PsycINFO 数据库记录 (c) 2016 APA，保留所有权利）
Varied stimulus quality and stimulus probability in 2 reaction time (RT) experiments with college students (n= 24). In Exp I Ss were run in a Sternberg paradigm with a fixed-set procedure, and stimulus quality was manipulated by varying the contrast between the stimulus and its background. Both stimulus probability and stimulus quality affected RT, and the interaction of these 2 variables was highly significant. In Exp II stimulus probability and quality were varied as in Exp I, but S's task was to name the stimulus. Again, stimulus probability and quality affected RT, although both effects were smaller than in Exp I. The interaction of stimulus probability and quality was also significant. Results of both experiments indicate that stimulus probability affects the stimulus encoding stage; this was interpreted as evidence against recent self-terminating search models of the memory scanning process.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
