The present study was carried out to differentiate orienting reflexes (OR) from defensive reflexes (DR) using 20 female college students as Ss. All Ss received 5 stimulations of 1 sec weak tone (1000 Hz, 40 dB) and 5 stimulation of 1 sec strong tone (white noise, 100 dB) in a randomized order and time interval. Finger pulse amplitude (PA), finger blood content (BC), heart rate (HR), and palmar skin potential reflex (SPR) were recorded simultaneously. BC decrease, HR deceleration, and negative wave of SPR occurred to weak stimulations, while increase, acceleration, and positive wave occurred to strong stimulations. Both intensities of stimulation produced a decrease in PA. These results were discussed in relation to the autonomic changes involved in OR and DR.
本研究以20名女大学生为被试，旨在区分定向反射（OR）和防御反射（DR）。所有被试按随机顺序和时间间隔接受5次1秒的弱音刺激（1000赫兹，40分贝）和5次1秒的强音刺激（白噪声，100分贝）。同时记录手指脉搏振幅（PA）、手指血容量（BC）、心率（HR）和手掌皮肤电位反射（SPR）。弱刺激引起BC下降、HR减速和SPR负波，而强刺激则引起BC增加、HR加速和SPR正波。两种强度的刺激均使PA降低。结合OR和DR所涉及的自主神经变化对这些结果进行了讨论。
