概括

法医检查人员在知道测试时产生了更多不确定的电话,表明霍桑效应. 盲目测试对于准确评估审查员在案例工作中的表现至关重要.

科学领域:

法医科学法医科学法医科学
科学中的认知偏见科学中的认知偏见

背景情况:

霍桑效应描述了当个人知道他们被观察时的行为变化.
关于存在的担忧存在.
战略审查员战略审查员
在法医科学中,这可能会改变测试和案例工作之间的决策门.

研究的目的:

测试枪支检查中不确定的呼叫率在发现和未发现的盲目测试之间是否有差异.
调查审查员意识对法医枪支分析决策的影响.

主要方法:

在休斯顿法医科学中心 (HFSC) 分析了5年来529个测试项目的比较结果.
对"发现" (已知被测试) 与"未发现" (未知被测试) 盲测试项目的不确定的呼叫率的比较.

主要成果:

对于发现的物品 (56.4%) 与未发现的物品 (39.3%) 相比,不确定的率显著更高,增加了43.5%.
这种模式在子弹比较 (83%对59%) 和弹盒比较 (29%对20%) 中持续存在.
在同源和不同源的比较中都观察到差异.

结论:

研究结果支持这样一个假设,即法医检查员的行为受到被测试的意识的影响 (霍桑效应).
该研究强调了使用盲测试的必要性,特别是当研究目标是准确评估法医检查员在案例工作场景中的表现时.

Naturalistic Observations

Naturalistic Observations

If you want to understand how behavior occurs, one of the best ways to gain information is to simply observe the behavior in its natural context. However, people might change their behavior in unexpected ways if they know they are being observed. How do researchers obtain accurate information when people tend to hide their natural behavior? As an example, imagine that your professor asks everyone in your class to raise their hand if they always wash their hands after using the restroom. Chances...
