科学领域:
- 神经科学是一个神经科学.
- 心理学 心理学 心理学
- 认知科学 认知科学
背景情况:
- 检测个体的认知改善或下降对于研究和临床实践至关重要.
- 可靠的变化方法提供了一个框架,用于评估认知表现的有意义变化随着时间的推移.
- 国家卫生研究院工具箱认知电池 (NIHTB-CB) 是评估认知功能的广泛使用的工具.
研究的目的:

- 在个人层面上确定可靠的流体认知的变化.
主要方法:
- 该研究使用了来自138名成年人 (18-85岁) 的测试重复测试数据,他们完成了来自NIHTB-CB的五项流体认知测试.
- 参与者大约隔一周进行评估,提供原始分数,年龄调整标准分数 (SS) 和人口调整T分数 (T).
- 可靠的变化被评估在变化得分周围使用类内相关系数 (ICC) 和置信区间 (CI),调整为实践效应.
主要成果:
- 流体认知复合和单个测试显示出良好至优异的测试-重新测试可靠性 (ICC范围:0.64-0.87).
- 计算了信心区间 (70%,80%,90%) 以确定可靠变化的门.
- 使用90%的CI和调整后的T分数,很大一部分参与者表现出可靠的变化:32.3%的人至少在一个测试中出现下降,36.6%的人至少在一个测试中出现改善.
结论:
- 对于个人来说,至少在一个流体认知测试中表现出可靠的变化是常见的,但在两个或更多的测试中不太常见.
- 对于每项测试,都确定了特定的截止值 (例如80%CI),并将复合得分确定为可靠的变化.
- 这些可靠的变化截止值可以在研究和临床环境中应用,以准确检测流体认知的个人变化.

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-Report Tests of Personality
350
Self-report inventories are objective personality assessments that use multiple-choice items or numbered scales, typically ranging from 1 (strongly disagree) to 5 (strongly agree). They are often called Likert scales after Rensis Likert. These inventories are widely used due to their ease of administration and cost-effectiveness. One of the most prominent examples is the Minnesota Multiphasic Personality Inventory (MMPI), initially developed in the 1940s to assess abnormal personality traits.

Comparing Experimental Results: Student's t-Test
1.6K
The t-test is a statistical method used to compare the sample mean with a population mean or compare two means from two data sets. The test statistic is calculated from the standard deviation, mean, and number of measurements in the data set at a selected confidence interval and then compared to a table of critical values at this confidence level. If the test statistic is smaller than the critical value, the null hypothesis is accepted. In this case, we state that the difference between the...
