Humans responded on multiple random-ratio (RR) random-interval (RI) schedules, and their verbalized performance awareness (PA; i.e., their ability to accurately describe what they did) was measured in three experiments. In Experiment 1, instructions informed participants that to earn points, either sometimes rapid responding and sometimes slow responding would work best (accurate instructions); rapid responding would work best (go fast instructions); spaced responding would work best (go slow instructions); or no advice was provided (minimal instructions). In Experiments 2 and 3, participants received either accurate or minimal instructions and were subject to extinction after a multiple RR-RI schedule. In all experiments, both performance awareness, and receiving accurate instructions, were related to schedule-sensitive responding, but were unrelated to one another - participants receiving accurate-rate instructions were not more likely to show performance awareness than those exposed to minimal instructions. Both higher performance awareness and exposure to accurate instructions predicted faster extinction in Experiment 2 but not in Experiment 3. The current results suggest that performance awareness rather than contingency awareness is more strongly related to humans displaying schedule-typical behavior and that this is not strongly related to any explicit verbal instructions that are given.
人类在多种随机比率(RR)和随机间隔(RI)的时间表上做出反应,并在三个实验中测量了他们言语表达的表现意识(PA;即他们准确描述自己行为的能力)。在实验1中,指示告知参与者,为了获得分数,有时快速反应有时缓慢反应效果最佳(准确指示);快速反应效果最佳(快速反应指示);间隔反应效果最佳(缓慢反应指示);或者不提供任何建议(最少指示)。在实验2和3中,参与者接受准确或最少的指示,并在多个RR-RI时间表后经历消退。在所有实验中,表现意识和接受准确指示都与对时间表敏感的反应有关,但彼此无关——接受准确比率指示的参与者并不比接受最少指示的参与者更有可能表现出表现意识。在实验2中,较高的表现意识和接受准确指示都预示着更快的消退,但在实验3中并非如此。目前的结果表明,表现意识而非偶然性意识与人类表现出符合时间表的典型行为的关系更为密切,而且这与所给出的任何明确的言语指示没有强烈关联。
