概括

本研究引入了修改后的持续关注响应任务 (mSART),以更好地追踪随时间推移的思维流浪 (MW) 动态. mSART有效量化了MW的范围,揭示了它在30分钟的会议中变得更深入.

科学领域:

认知心理学认知心理学
神经科学是一个神经科学.
心理测量方法心理测量方法

背景情况:

心灵流浪 (MW) 是注意力从外部任务转移到内部思想.
持续关注响应任务 (SART) 常用于测量MW,但缺乏时间动态跟踪.
一个修改后的SART (mSART) 已被开发出来,以捕获和量化随时间推移的MW状态.

研究的目的:

开发和验证一个修改的持续注意力响应任务 (mSART) 用于动态思维流浪 (MW) 测量.
使用来自mSART的行为数据量化思维游荡的程度.
为了调查在持续的注意力任务期间心灵漫游的时间动态.

主要方法:

179名参与者完成了为期30分钟的mSART,使用操纵的no-go刺激频率来控制任务难度.
收集了行为数据,包括错误率,平均反应时间 (RT),RT变化系数 (CV) 和d'.
协差分析 (ANCOVA) 和ANOVA用于分析数据,实验分为六个时间窗口.

主要成果:

在不同精神流浪水平中,发现了平均RT,RT CV和d'的显著差异.
观察到,在30分钟的实验时间内,心灵流浪逐渐加深.
平均RTs (p < .001),RTCV (p < .001) 和d' (p < .001) 的统计学意义得到证实.

结论:

修改后的持续注意响应任务 (mSART) 有效量化了思维游荡 (MW) 的程度.
该mSART利用变化在no-go刺激频率来评估MW.
为了使用mSART进行最佳的MW评估,确定了大约20分钟的推实验持续时间.

High-Level and Low-Level Awareness

High-Level and Low-Level Awareness

Controlled processes in human consciousness represent high-alert mental states where individuals deliberately focus their attention on achieving specific goals. Controlled processes can be seen in situations like mastering new technology, where a person might become so absorbed that they ignore surrounding distractions. Such processes involve selective attention, requiring one to concentrate on particular elements of experience while disregarding others. These are governed by executive...

Altered States of Awareness

Altered States of Awareness

Altered states of consciousness represent significant deviations from one's normal mental state. These deviations can range from subtle changes in awareness to profound transformations in perception, thought processes, and sensory experiences. Altered states of consciousness can be triggered by various factors, including drug use, meditation, hypnosis, illness, or even intense fatigue.
The ingestion of substances like stimulants or hallucinogens leads to chemical alterations in the brain...
