具有更高幻觉倾向的个体在产生自己的声音时表现出改变的感官反处理和注意力控制. 这表明这些变化对整个频谱的幻觉倾向至关重要.
科学领域:
- 神经科学是一个神经科学.
- 心理学 心理学 心理学
背景情况:
- 听觉语言幻觉与改变的感官反和注意力控制有关.
- 幻觉易感 (HP) 在连续上存在,但这些因素在整个频谱中的相互作用尚未得到充分理解.
研究的目的:
- 为了研究感官反处理和注意力控制在幻觉倾向连续的相互作用.
- 检查这些过程在自我语音生成过程中是如何受到影响的.
主要方法:
- 使用电脑电图 (EEG),40名参与者表现出不同水平的HP.
- 参与者自行生成 (按下按) 并被动地倾听自己的声音,这些声音被操纵为语音质量 (中性到愤怒的形态).
- 测量N100和P200抑制效应作为感官处理的指标.
主要成果:
- 随着HP的增加,无论语音质量如何,都观察到N100和P200抑制效应的减少.
- 这表明,在自我语音制作过程中,高HP个体的错误意识和注意力分配增加.
- 结果表明,感官反处理和/或注意力控制的改变是潜在的机制.
结论:
- 在自我发声过程中,感官反处理和/或注意力控制的变化是幻觉倾向连续的核心特征.
- 这些变化似乎是基本的,无论临床状态在体验语音听觉的个体.
