概括
即使是一个独立的,强制选择的,基于记忆的 (Fr-FC-MB) 性能有效性测试 (PVT) 失败也会显著损害退伍军人的记忆得分. 这就意味着要仔细检查那些在单一的PVT中失败的人.
科学领域:
- 神经心理学 神经心理学
- 认知评估 认知评估
- 退伍军人健康 退伍军人的健康
背景情况:
- 在只有一个性能有效性测试 (PVT) 失败时,对解释认知测试结果缺乏共识.
- 性能有效性测试对于识别认知评估中不可信的努力至关重要.
研究的目的:
- 调查一个独立的,强制选择的,基于内存的 (Fr-FC-MB) PVT失败对大型退伍军人样本内存性能的影响.
- 为了确定一个单一的Fr-FC-MBPVT失败是否会显著影响后续的记忆测试成绩.
主要方法:
- 研究了1353名退伍军人的数据.
- 评估了零,一个或两个Fr-FC-MB PVT (Memory Malingering Trial 1或医学症状有效性测试) 的失败对记忆测量的影响.
- 使用了加利福尼亚州的口头学习测试-II (CVLT-II) 和简短的视觉空间记忆测试-R (BVMT-R).
主要成果:
- 与没有失败的退伍军人相比,失败一次Fr-FC-MBPVT的退伍军人表现出所有记忆指数的显著下降.
- 对于BVMT-R (d = -0.9) 和CVLT-II (d = -1.0) 两种方法,均观察到较大的平均效应大小.
- 那些失败一次PVT的人的记忆得分与那些失败两次PVT的人相似.
结论:
- 即使是单个Fr-FC-MBPVT的失败也会极大地和负面地影响内存性能.
- 在确定无效测试性能时,需要更多的细微差别和灵活性.
- 一个 Fr-FC-MB PVT 失败的个人需要对其表现的可信性进行更密切的审查.

Reliability and Validity
12.7K
Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.

Self-Presentation: Self-Monitoring and Self-Handicapping
39.0K
People can go to great lengths to protect their self-image and present themselves in ways that they want others to see them. Sociologist Erving Goffman presented the idea that a person is like an actor on a stage. Calling his theory dramaturgy, Goffman believed that we use “impression management” to present ourselves to others as we hope to be perceived. Each situation is a new scene, and individuals perform different roles depending on who is present (Goffman, 1959). Think about...

Stereotype Threat and Self-fulfilling Prophecies
37.6K
When we hold a stereotype about a person, we have expectations that he or she will fulfill that stereotype. A self-fulfilling prophecy is an expectation held by a person that alters his or her behavior in a way that tends to make it true. When we hold stereotypes about a person, we tend to treat the person according to our expectations. This treatment can influence the person to act according to our stereotypic expectations, thus confirming our stereotypic beliefs. Research by Rosenthal and...

When performing a hypothesis test, there are four possible outcomes depending on the actual truth (or falseness) of the null hypothesis and the decision to reject or not.

Significance Testing: Overview
3.4K
Significance testing is a set of statistical methods used to test whether a claim about a parameter is valid. In analytical chemistry, significance testing is used primarily to determine whether the difference between two values comes from determinate or random errors. The effect of a particular change in the measurement protocol, analyst, or sample itself can cause a deviation from the expected result. In the case of a suspected deviation/outlier, we need to be able to confirm mathematically...

Accuracy and Errors in Hypothesis Testing
201
Hypothesis testing is a fundamental statistical tool that begins with the assumption that the null hypothesis H0 is true. During this process, two types of errors can occur: Type I and Type II. A Type I error refers to the incorrect rejection of a true null hypothesis, while a Type II error involves the failure to reject a false null hypothesis.
In hypothesis testing, the probability of making a Type I error, denoted as α, is commonly set at 0.05. This significance level indicates a 5%...
