概括
当模拟犯罪视频包含声音时,没有观察到武器聚焦效应 (WFE). 对犯罪者外表的记忆不受对象类型的影响,这挑战了关于注意力和不寻常物品的现有理论.
科学领域:
- 认知心理学 认知心理学
- 法医心理学 法医心理学
- 视觉注意力 视觉注意力
背景情况:
- 武器聚焦效应 (WFE) 表明,由于武器的存在,对一个人的外表的记忆受到损害.
- 不寻常物品假设认为,像武器这样的不寻常物品会吸引注意力,将注意力从事者身上转移.
研究的目的:
- 调查物体异常和声音在武器聚焦效应中的作用.
- 检查不同的物体 (武器,不寻常的非武器,中性) 如何影响视觉注意力和记忆对犯罪者的外观.
主要方法:
- 参与者观看了模拟犯罪视频,其中犯罪者携带武器,一个不寻常的非武器物体或一个中立物体.
- 监测眼睛的运动,以分析视觉注意力模式.
- 评估了对事者的外表的记忆.
主要成果:
- 没有发现对象观看时间的显著差异.
- 当她拿着一个不寻常的非武器物体,但不是武器时,犯罪者的观看时间减少了.
- 武器的存在将注意力从事者的脸上转移到她的身体上,特别是在早期的场景观看中.
- 主要实验中,对象类型对犯罪者的外观记忆没有影响.
- 在一个在线实验中观察到WFE,但只有当视频没有声音时才会出现.
结论:
- 这些发现不支持关于长时间注意力转移的不寻常项目假设.
- 似乎涉及复杂的注意力效应,而不是简单的转变.
- 主要实验中没有WFE,这表明声音可能起着至关重要的作用.
- 这项研究强调了在高兴情景中视觉注意力和记忆的细微性质.

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...
Group Design
The most basic experimental design involves two groups: the experimental group and the control group. The two groups are designed to be the same except for one difference— experimental manipulation. The experimental group gets the experimental manipulation—that is, the treatment or variable being tested—and the control group does not. Since experimental manipulation is the only difference between the experimental and control groups, we can be sure that any differences between the two are due to...
