Feedback of information has consistently shown positive results in human inspection, provided it is given in a timely and appropriate manner. Feedback serves as the basis of most training schemes; traditionally this has been performance feedback. Other forms of feedback which provide strategy information rather than performance information may have a role in improving inspection. This study compared performance feedback and cognitive feedback in a realistic simulation of an aircraft structural inspection task. Performance (time, errors) feedback showed the greatest improvements in performance measures. Cognitive feedback enhanced efficiency measures of search strategy. When cognitive feedback consisted of visual representations of the path and the coverage of the search sequence, subjects also were able to use this task information to improve their search performance.
信息反馈在人工检查中一直显示出积极的效果，前提是反馈要及时且恰当。反馈是大多数培训方案的基础；传统上这一直是绩效反馈。其他提供策略信息而非绩效信息的反馈形式可能在改进检查方面发挥作用。本研究在飞机结构检查任务的真实模拟中比较了绩效反馈和认知反馈。绩效（时间、错误）反馈在绩效指标方面显示出最大的改进。认知反馈提高了搜索策略的效率指标。当认知反馈由搜索序列的路径和覆盖范围的视觉表示组成时，受试者也能够利用这些任务信息来提高他们的搜索绩效。
