A Study for Behavioral Control on Experimentally induced Stress.

1.实验诱发疼痛的自我控制研究：对冷加压痛的行为控制策略进行了研究。主要研究结果如下：(1)本实验以5℃ﾟC冷水为最适。(2)皮肤温度在浸泡过程中下降幅度较大，在较冷的水条件下浸泡后回升较快。这种情况也引发了负面影响。(3)在痛觉和皮温恢复过程中存在显著的个体差异。(4)A型被试的忍耐力较弱，但面对情境的能力较强。(5)对疼痛控制策略进行了分类，确定了它们的特点。(6)刻意注意任务、分心、自我控制和表象对疼痛控制有效。(7)言语控制自我效能感对疼痛的影响不明显。(8)呼吸控制、自体训练和放松是有效的疼痛控制策略。应激对心血管反应的影响。研究了语言应激源对血压的影响。主要研究结果如下：(1)确定了应激源的四种反应模式。(2)DBP反映在应激反应上。(3)高应力反应堆有较大的应力响应。(3)在低应力反应堆中，可引起较小的应力反应，并立即恢复。

1. Studies of the self-control of the experimentally induced pain.Strategies for behavioral control of cold pressor pain were examined. Main findings were as follows : (1) Cold water of 5 ^ﾟC was most appropriate for this kind of experiment. (2) Skin temperature reduced more during immersion and increased more quickly after withdrawing in the colder water condition. The condition also elicited negative affects. (3) Marked individual differences were observed in the pain sensation and the recovery process of skin temperature. (4) Type A subjects were weak in the trouble to tolerance, but they faced to the situations. (5) Strategies for pain control were classified and their characteristics were confirmed. (6) Intentional attention to tasks, distraction, self-control and imagery were effective for pain control. (7) Effects of verbally controlled self-efficacy on pain were not clear. (8) Respiratory control, autogenic training and relaxation were promisingstrategies for pain control.2. Effects of stress on cardiovascular responses.Influences of verbal stressor on blood pressure were examined. Main findings were as follows : (1) Four patterns of responses to stressors were confirmed. (2) DBP reflected on stress responses. (3) Large stress responses were observed in high-stress reactors. (3) Smaller stress responses were elicited in low-stress reactors and recovered immediately.
