- 心理学 心理学 心理学
- 成研究 研究成研究
背景情况:
- 在认知任务中减少P3事件相关潜能 (ERP) 幅度与酒精问题有关.
- 对酒精线索的P3振幅增加也与酒精使用和问题有关.
- 这些关于P3幅度和酒精参与的不一致的发现缺乏整合.
研究的目的:
- 调查不同环境中的P3振幅是否反映了导致问题性酒精参与 (PAI) 的不同因素.
- 通过P3测量,探索PAI病因学的异质性.
- 整合与PAI相关的Target-P3和与酒精相关的P3 (ACR-P3) 的发现.
主要方法:
- 在电脑电图 (EEG) 记录过程中,156名新兴成年人完成了认知 (精神旋转) 和暗示视觉任务.
- 参与者还填写了关于特征抑制,酒精使用和与酒精有关的问题的问卷.
- 回归分析检查了P3幅度和PAI隐性变量之间的关联,控制最近的饮酒.
主要成果:
- 目标-P3振幅与PAI负相关,而ACR-P3振幅与PAI积极相关.
- 两项P3测量均独特地预测了最近饮酒以外的PAI.
- 特征脱抑制调解了Target-P3和PAI之间的关系,但不是ACR-P3和PAI.
结论:

P-value is one of the most crucial concepts in statistics.
P-value stands for the probability value. P-value is the probability that, if the null hypothesis is true, the results from another randomly selected sample will be as extreme or more extreme as the results obtained from the given sample.
A large P-value calculated from the data indicates to not reject the null hypothesis. But a higher P-value does not mean that the null hypothesis is true. The smaller the P-value, the more...

The process of hypothesis testing based on the P-value method includes calculating the P- value using the sample data and interpreting it.
First, a specific claim about the population parameter is proposed. The claim is based on the research question and is stated in a simple form. Further, an opposing statement to the claim is also stated. These statements can act as null and alternative hypotheses: a null hypothesis would be a neutral statement while the alternative hypothesis can...
