恐惧发生与预防的实验研究：──Ⅱ、强噪音下不同处理背景动物身心变化的观察分析

采用生理心理学的实验方法．对强噪音下四组不同处理背景大鼠的旷场反应、援食、饮水、排泄和尿生物化学等方面进行比较。结果发现：①Ⅰ组（强刺激组）的各类指标均发生情绪性（恐惧）改变。与２组（预防训练Ⅰ组）、３组（预防训练Ⅱ组）、４组（控制组）以及自身基线（ＭＡＯ）比较差异显著；②适应性训练有助于防止大鼠恐惧发生及上述各类指标发生异常．③由于训练的方法不同，预防的效果也不同。３组与４组比较无显著差异，２组与４组比较某些指标有显著差异。④１组和２组部分大鼠出现皮肤、消化道病变。

EXPERIMENTAL RESEARCH ON THE CAUSE AND PREVENTION OF FEAR: THE BIOLOGICAL AND PSYCHOLOGICAL CHANGES IN ANIMALS AGAINST DIFFERENT BACKGROUNDS UNDER POWERFUL NOISE

This was a study of four groups of SD type rats against different backgrounds under powerful noise. Our findings: 1)one group's walking in tile open field was poorer than and its defecation was higher than those of the other groups: 17OHGS, 17-KGS were higher and MAO was lower than thoes of tile rest: 2) Training in desensitization from noise was conducive to the rats' adaptability to and reduction of fear under powerful noise for the 2nd and 3rd groups ; 3)The best training method was a combination of gradually in creasing noise intensity and atimulation time, and equally distributed experimental days.
