概括
在比较排列程序时,同时呈现显示出比顺序停止规则排列更好的区别性. 顺序呈现对准确性和偏差的影响取决于其他程序方面,而不仅仅是项目顺序.
科学领域:
- 认知心理学 认知心理学
- 法医科学 法医科学 法医科学
背景情况:
- 目击者识别的准确性因不同的排队程序而异.
- 之前的研究表明,关于可歧视性和响应偏差的同时与顺序排队的结果相矛盾.
研究的目的:
- 在同时,顺序停止规则和顺序两圈 (类似于英国) 的阵容程序中比较可歧视性和响应偏差.
- 调查顺序呈现与其与其他程序元素的相互作用的孤立效应.
主要方法:
- 一个大规模的实验,使用六个项目摄影阵列.
- 参与者同时观看呈现的阵容,顺序地使用停止规则,或顺序地使用两圈和项目复习.
- 测量了可辨别性 (准确性) 和响应偏差 (宽容/严格性).
主要成果:
- 同时排队产生了比顺序停止规则排队更高的歧视性.
- 在同时和连续的两圈阵容之间,或在两个连续类型之间,没有发现显著的可区分差异.
- 响应偏差在连续的两圈阵容中是最宽容的,其次是同时,然后是连续的停止规则.
结论:
- 单独的顺序项目呈现可能不会显著影响歧视性或响应偏差.
- 在顺序排列 (如英国) 中观察到的效应可能源于顺序呈现和其他程序特征之间的相互作用.
- 了解这些相互作用对于优化目击者识别程序至关重要.

Eyewitness Memory
105
Eyewitness memory refers to the recollection of events by someone who has directly witnessed them, often serving as critical evidence in legal settings. This type of memory is commonly used in criminal cases where a witness describes details like a suspect's appearance, clothing, or behavior during a crime. However, despite its perceived reliability, eyewitness memory is prone to significant errors.
One such error is memory distortion, which occurs because human memory does not function...

Serial Position Effect
169
The serial position effect is a cognitive phenomenon where individuals are more likely to recall the first and last items in a list compared to those in the middle. This effect is divided into the primacy effect and the recency effect. The primacy effect is observed when the initial items in a list are remembered better. This occurs because these items are rehearsed more frequently or receive more elaborative processing, allowing them to be encoded into long-term memory more effectively. For...
