- 心理学 心理学 心理学
- 精神病学是一个精神病学.
背景情况:
- 附带负变量 (CNV) 是一种脑电图 (EEG) 测量方法,通常与精神病特征相关研究.
- 在文献中,关于精神病如何影响CNV振幅存在不一致.
研究的目的:
- 系统地审查和对现有的关于心灵病态 CNV 振幅调节的文献进行元分析.
- 澄清精神病症和CNV之间的关系,特别是区分早期 (iCNV) 和晚期 (tCNV) 组件.
主要方法:
- 一项系统的文献搜索发现了9项研究,共有317名参与者.
- 进行了三个元分析:总体CNV,iCNV和tCNV.
- 一项定性分析检查了与精神病的维度特征相关的CNV幅度.
主要成果:
- 对于CNV或iCNV,没有发现有意义的整体效应.
- 在具有更高精神病特征的参与者中观察到更大的tCNV振幅的显著发现 (g = -0.58).
- 没有发现显著的异质性或调节性研究特征.
结论:
- 这些发现表明,晚期CNV (tCNV) 幅度可能被精神病特异性调节,与此前的假设相反.

However, these approaches provide an optimistic perspective for individuals seeking to change their behaviors. Rather than concentrating on intrinsic personality traits, behavioral approaches suggest that even longstanding habits can be modified by changing the reward contingencies that maintain them.

At the heart of this discipline lies the study of how genes influence physical traits, behaviors, and susceptibility to diseases. Each person carries a unique genetic code that subtly or significantly shapes their psychological and behavioral landscape.
