人们能学会在不受干扰的情况下同时执行两项任务吗?为了回答这个问题,作者在心理不应期(PRP)实验中训练了6名参与者36次,其中任务1要求对听觉刺激做出快速声音反应,任务2要求对视觉刺激做出快速手动反应。最初发现的大的PRP效应(会话1中的353毫秒)在练习过程中缩小到仅约40毫秒,对于6名参与者中的1名完全消失。在实践中,PRP效应的减少比以前报道的要大得多。所获得的刺激起始不同步与三种任务难度操作(任务1判断难度、任务2刺激对比和任务2映射兼容性)之间的因素交互模式支持练习前后双任务干扰的延迟(瓶颈)解释。
Can people learn to perform two tasks at the same time without interference? To answer this question, the authors trained 6 participants for 36 sessions in a Psychological Refractory Period (PRP) experiment, where Task 1 required a speeded vocal response to an auditory stimulus and Task 2 required a speeded manual response to a visual stimulus. The large PRP effect found initially (353 ms in Session 1) shrank to only about 40 ms over the course of practice, disappearing entirely for 1 of the 6 participants. This reduction in the PRP effect with practice is considerably larger than has been previously reported. The obtained pattern of factor interactions between stimulus onset asynchrony and each of three task difficulty manipulations (Task 1 judgment difficulty, Task 2 stimulus contrast, and Task 2 mapping compatibility) supports a postponement (bottleneck) account of dual-task interference, both before and after practice.
