概括

在神经类型患者中,实验诱导的听觉语言幻觉不是左侧的,也不是幻觉倾向预测的. 这表明声音听觉存在于连续性上,在整个人口中都有共同的机制.

科学领域:

认知神经科学认知神经科学
心理学心理学心理学
精神病学是一个精神病学.

背景情况:

听觉语言幻觉 (AVHs) 在精神病中很常见,也发生在神经类型个体中.
患有精神分裂症和容易幻觉的神经类型的人在听觉任务中表现出类似的假阳性反应.
这表明AVHs可能存在于具有共享底层机制的连续体上.

研究的目的:

调查神经类型中实验诱导的AVH是否是左侧的.
为了确定是否幻觉倾向或听觉图像预测诱导的AVHs.
探索AVHs作为一个连续的现象.

主要方法:

50名神经类型参与者接受了帕夫洛夫式的视听调节,将单词与听觉刺激联系起来.
接下来是一项信号检测任务,参与者在白噪声中识别了目标词.
使用单耳听觉刺激来测试左侧化.

主要成果:

帕夫洛夫条件化成功诱导了神经类型参与者的虚假阳性 (FP).
在左耳和右耳之间,FP速率,灵敏度和偏差没有差异.
诱导的FP并没有通过自我报告的幻觉倾向或听觉图像来预测.

结论:

在神经类型中实验诱导的AVH并非左侧化,挑战横向化作为幻觉的定义特征.
这些发现支持AVH的观点,认为AVH在一般人群中是一个持续的现象.
在神经类型中研究诱导的AVH可能会阐明临床幻觉背后的机制.

Lateralization

Lateralization

Brain lateralization refers to the division of mental processes and functions between the two hemispheres of the brain, a phenomenon that optimizes neural efficiency and underpins complex abilities in humans. This specialization allows each hemisphere to perform tasks where it has a comparative advantage, facilitating more refined cognitive capabilities across different domains.

Positive Symptoms Schizophrenia: Hallucinations and Delusions

Schizophrenia is a complex psychiatric disorder characterized by a range of symptoms that significantly impact cognition, behavior, and emotional regulation. Among these, the positive symptoms stand out as they involve the addition or exaggeration of normal mental functions, deviating markedly from typical behavior and perception. Hallucinations and delusions are prominent positive symptoms, each profoundly affecting the individual's experience of reality.
