Poor performance in pressure-filled situations, or "choking under pressure," has largely been explained by two different classes of theories. Distraction theories propose that choking occurs because attention needed to perform the task at hand is coopted by task-irrelevant thoughts and worries. Explicit monitoring theories claim essentially the opposite-that pressure prompts individuals to attend closely to skill processes in a manner that disrupts execution. Although both mechanisms have been shown to occur in certain contexts, it is unclear when distraction and/or explicit monitoring will ultimately impact performance. The authors propose that aspects of the pressure situation itself can lead to distraction and/or explicit monitoring, differentially harming skills that rely more or less on working memory and attentional control. In Experiments 1-2, it is shown that pressure that induces distraction (involving performance-contingent outcomes) hurts rule-based category learning heavily dependent on attentional control. In contrast, pressure that induces explicit monitoring of performance (monitoring by others) hurts information-integration category learning thought to run best without heavy demands on working memory and attentional control. In Experiment 3, the authors leverage knowledge about how specific types of pressure impact performance to design interventions to eliminate choking. Finally, in Experiment 4, the selective effects of monitoring-pressure are replicated in a different procedural-based task: the serial reaction time task. Skill failure (and success) depends in part on how the performance environment influences attention and the extent to which skill execution depends on explicit attentional control.
在充满压力的情况下表现不佳,或“压力下窒息”,主要可以用两类不同的理论来解释。分心理论认为,窒息是因为手头任务所需的注意力被与任务无关的想法和担忧所占据。而明确监控理论则声称,恰恰相反,压力促使个体以一种破坏执行的方式密切关注技能过程。尽管这两种机制在某些情况下都被证明存在,但尚不清楚分心和/或明确监控何时会最终影响表现。作者提出,压力情境本身的某些方面可能会导致分心和/或明确监控,从而对更多或更少依赖工作记忆和注意力控制的技能产生不同的影响。在实验 1-2 中,研究表明,导致分心的压力(涉及表现相关的结果)会严重损害严重依赖注意力控制的基于规则的类别学习。相比之下,导致对表现进行明确监控的压力(由他人监控)会损害信息整合类别学习,因为这种学习被认为在不需要大量工作记忆和注意力控制的情况下效果最佳。在实验 3 中,作者利用关于特定类型的压力如何影响表现的知识来设计干预措施,以消除窒息。最后,在实验 4 中,在另一个基于程序的任务——序列反应时间任务中,复制了监控压力的选择性影响。技能失败(和成功)部分取决于表现环境如何影响注意力,以及技能执行在多大程度上依赖于明确的注意力控制。
