PERSONALITY FACTORS AND PSYCHOPHYSIOLOGICAL RESPONSE TO CHANGING STIMULUS INPUT

这个项目的目标是调查 在个性、感觉阈值和 正常人和正常人自主神经系统(ANS)活动 研究ANS活动的种族差异。双侧皮肤 电导和心率在#年的两次会议中被记录 哪些是恒定和可变强度的色调和灯光 呈现、听觉和双闪阈值(TFT) 由允许信号检测分析的方法确定。 一种确定不舒适响度级别的程序 也曾被使用过。几个标准化的人格测试是 还给出了。这些量表包括感觉寻求量表， 外向、神经质、精神质、场依赖和 焦虑。此外，还采取了横向综合措施 优势度以及“扭矩”的度量都已给出。 (顺时针画圆圈)被假设为 反映出神经整合缺陷，并与 未来的精神病理学。一个操作ANS的程序 在实验中唤醒，分心效果最小-- 从仰卧到站立的姿势变化--正在被用来研究 诸如基本水平对响应性的影响、 唤醒对表现的影响，以及人格的影响 这段关系的变数。该项目允许测试 ANS活动关系的几种理论模型， 感官敏感度和个性，其中一些有 对精神病理学病因学的影响。测试的结果 皮肤电导变量的侧向性之间的关系 还将进行行为偏侧分析，以查看推论 关于偏侧化的大脑功能可以由这样的 变量。

The objectives of this project are to investigate relationships among differences in personality, sensory thresholds, and autonomic nervous system (ANS) activity in normal humans and to study racial differences in ANS activity. Bilateral skin conductance and heart rate have been recorded in two sessions in which constant and variable intensity tones and lights are presented and auditory and two-flash thresholds (TFT) determined by methods which permit signal detection analyses. A procedure for determining the uncomfortable loudness level has also been used. Several standardized personality tests were also given. These include scales of sensation-seeking, extraversion, neuroticism, psychoticism, field dependence and anxiety. In addition comprehensive measures of lateral dominance have been given as well as a measure of "torque" (clockwise drawing of circles) which has been hypothesized to reflect a neurointegrative deficit and be related to risk for future psychopathology. A procedure for manipulating ANS arousal experimentally with minimal distracting effects--a change in posture from supine to standing--is being used to study such problems as the effects of base levels on responsivity, the effects of arousal on performance, and the effects of personality variables on this relationship. This project allows testing of several theoretical models of the relationships of ANS activity, sensory sensitivity, and personality, some of which have implications for the etiology of psychopathology. Tests of the relationships between laterality in skin conductance variables and behavioral laterality will also be done to see if inferences about lateralized brain function can be made from such variables.
