完成后错误（PCE）是一种程序性错误，即使个人具有正确执行任务所需的知识，也会发生这种错误。在执行“关键任务”步骤后，如果个人在开始新任务之前忘记执行所需的“相关步骤”，则可能发生PCE。研究表明，PCE对外部影响很敏感。例如，如果一个人正在考虑“其他事情”或被打断，那么在复印完文件后忘记收集原始文件的可能性更大。我们设计了两种游戏环境来测试PCE的系统性，在这两种环境中，参与者积极地试图避免PCE。在这两个实验中，如果发生PCE，参与者的得分将被重置为零。结果表明，这种惩罚对游戏过程中错误的系统性没有显著影响。研究还发现，pce发生的可能性可以通过与执行“关键任务”步骤相关的内在困难或个人准确记忆与任务相关信息的能力来预测。这意味着，即使个人有动机避免pce，用户性能仍然容易受到这种错误类型的影响。在要求苛刻的环境中，此漏洞可能更容易暴露。
Post-completion error (PCE) is a type of procedural error that occurs even when an individual has the knowledge required to perform the task correctly. After performing a ‘task critical’ step a PCE can occur if an individual forgets to perform a required ‘related step’ before starting a new task. Research has demonstrated that PCE is sensitive to external influences. For example, forgetting to collect the original document after making photocopies is more likely if an individual is thinking about ‘other things’ or is interrupted. Two gaming environments were designed to test the systematicity of PCE where participants were actively trying to avoid them. In both experiments a participant’s score was reset to zero if a PCE occurred. Results showed that this penalty did not significantly influence the systematicity of the error within a gaming session. It was also found that the likelihood of PCEs occurring could be predicted by the intrinsic difficulty associated with performing the ‘task critical’ step or by an individual’s ability to accurately remember information relevant to the task. This implies that even when individuals are motivated to avoid PCEs, user performance remains vulnerable to this error type. Within demanding environments, this vulnerability is likely to be more exposed.
