Sixty-five subjects experienced 2 cold pressor immersions. Following the initial immersion, subjects participated in the Velten mood induction procedure by reading either depressive, neutral or elative statements. The sensory discriminative response to pain was measured by ratings of pain, and the affective-reactive response to pain was measured by pain tolerance. Pain tolerance, but not pain ratings, were affected by mood inductions with subjects in the depression condition shortening their tolerance times more than the subjects in the neutral condition and the subjects in the elative condition increasing their tolerance times.
65名受试者经历了2次冷压浸入试验。在首次浸入后，受试者通过阅读抑郁、中性或欢快的陈述参与了韦尔腾情绪诱导程序。对疼痛的感觉辨别反应通过疼痛评分来衡量，对疼痛的情感反应通过疼痛耐受性来衡量。疼痛耐受性而非疼痛评分受到情绪诱导的影响，处于抑郁状态的受试者比处于中性状态的受试者缩短了耐受时间，而处于欢快状态的受试者则延长了耐受时间。
