生物控制论系统利用心理生理学的实时变化来适应计算机控制和功能的各个方面，例如自适应自动化。这种系统设计方法基于一个假设，即心理生理变化代表了操作员主观状态的隐含波动，例如情绪、动机、认知。本研究旨在探讨心理生理测量与个体主观状态变化之间的趋同效度。35名参与者在连续4个20分钟的时间段内完成了高要求的多属性任务单元（MATB）。收集了一系列心理生理数据（EEG、ECG、皮肤电导水平（SCL）、EOG、呼吸频率），并将其与Dundee应激状态问卷（DSSQ）测量的主观状态变化相关联。数学成绩在任务时间上是稳定的；由于持续的表现，心理生理活动表现出预期的变化。对DSSQ进行了三个主观元因素的分析：任务投入、痛苦和担忧。多元回归分析显示，心理生理学预测了任务投入和痛苦的很大一部分方差，但对担忧元因素却没有预测。讨论了生物控制系统发展的后果。(c) 2005 Elsevier B.V.版权所有
Biocybernetic systems utilise real-time changes in psychophysiology in order to adapt aspects of computer control and functionality, e.g. adaptive automation. This approach to system design is based upon an assumption that psychophysiological variations represent implicit fluctuations in the subjective state of the operator, e.g. mood, motivation, cognitions. A study was performed to investigate the convergent validity between psychophysiological measurement and changes in the subjective status of the individual. Thirty-five participants performed a demanding version of the Multi-Attribute Task Battery (MATB) over four consecutive 20-min blocks. A range of psychophysiological data were collected (EEG, ECG, skin conductance level (SCL), EOG, respiratory rate) and correlated with changes in subjective state as measured by the Dundee Stress State Questionnaire (DSSQ). MATB performance was stable across time-on-task; psychophysiological activity exhibited expected changes due to sustained performance. The DSSQ was analysed in terms of three subjective meta-factors: Task Engagement, Distress and Worry. Multiple regression analyses revealed that psychophysiology predicted a substantial proportion of the variance for both Task Engagement and Distress but not for the Worry meta-factor. The consequences for the development of biocybernetic systems are discussed. (c) 2005 Elsevier B.V. All rights reserved.
