While performing a simple task of following: a suture while closing a surgical wound in a simulated environment, we hypothesized that negative reinforcement results in increased procedural errors, longer operating time and poorer trainee satisfaction. We aimed to measure the effect on participant performance and the perception of the instructor, following positive or negative supervisor feedback during the task. A blinded randomized study was conducted assessing positive and negative supervisor feedback styles on participant performance in a simulated operation room. Students performed the task twice, with a reflection in between the repeated task. We found that the change in procedure time between the two tasks was adversely affected by feedback style. Participants receiving negative feedback sought cues to improve. From this study, it was found that negative supervisor feedback has the potential to adversely affect elements of performance. Despite this, participants receiving negative feedback express a willingness to improve their performance by seeking cues from the supervisor.
在模拟环境中进行缝合手术伤口这一简单任务时，我们假设负强化会导致程序错误增加、手术时间延长以及学员满意度降低。我们旨在衡量在任务过程中，主管给予正面或负面反馈后，对参与者表现和指导者认知的影响。我们进行了一项双盲随机研究，评估在模拟手术室中主管的正面和负面反馈方式对参与者表现的影响。学生们执行该任务两次，在重复任务之间进行反思。我们发现，两次任务之间的操作时间变化受到反馈方式的不利影响。收到负面反馈的参与者会寻求改进的线索。从这项研究中发现，主管的负面反馈有可能对表现的各个方面产生不利影响。尽管如此，收到负面反馈的参与者表示愿意通过向主管寻求线索来提高自己的表现。
