将愉快、中性或不愉快的图片呈现在连续的系列中，并在躯体(波纹肌电[EMG]活动)和内脏(心率和皮肤电导)系统中评估重复暴露于相同情感价态图片的效果。探测刺激(惊吓或反应时间探测)被用来指示加工过程中伴随的情绪和注意力。在所有反应系统中，情感辨别随时间保持，并发现波纹肌电反应的敏感化。对反应时间的反应探测到了注意分配的差异，作为认知和情感变量的函数在这个范例中。综上所述，这些数据表明，呈现一系列类似价位的情感图片会产生情绪反应，这些情绪反应要么在这里使用的时间间隔内保持，要么被敏化，但并不习惯。
Pleasant, neutral, or unpleasant pictures were presented in a continuous series, and the effects of repetitive exposure to pictures of the same affective valence were assessed in somatic (corrugator electromyographic [EMG] activity) and visceral (heart rate and skin conductance) systems. Probe stimuli (startle or reaction time probes) were presented to index emotional and attentional concomitants of processing. affective discrimination was maintained across time in all response systems, and sensitization was found for the corrugator EMG response. Responses to reaction time probes indexed differences in attentional allocation as a function of cognitive and affective variables in this paradigm. Taken together, the data suggest that presentation of a series of affective pictures of similar valence produces emotional reactions that are either maintained or sensitized across the temporal intervals used here but that do not habituate.
