我们进行了两项研究，以调查对单侧触觉探针的惊吓反应的情感调节，并确定这种调节是否侧化。右撇子的大学生在观看令人愉快的、中性的和令人不愉快的图片时，向左或右太阳穴吹气。在研究1的两个试验区（n = 48）中，探针呈现的侧位是不同的，但在研究2的试验区（n = 48）中是随机变化的。各研究的初步结果一致。复制并扩展了声学探针的发现，在不愉快的画面中，触觉探针的眨眼反应比愉快的画面更大。然而，在两项研究或联合分析中，惊吓的情感调节在探针呈现的两侧（感觉侧性）或反应的两侧（运动侧性）之间没有可靠的差异。
Two studies were conducted to investigate affective modulation of startle responses to unilateral tactile probes and to determine whether such modulation is lateralized. Right-handed undergraduates received airpuffs to the left or right temple while viewing pleasant, neutral, and unpleasant pictures. Side of probe presentation was varied between the two trial blocks of the experiment in Study 1 (n = 48) but varied randomly within trial blocks in Study 2 (n = 48). Primary results were consistent across studies. Replicating and extending the findings for acoustic probes, eyeblink responses to tactile probes were larger during unpleasant than during pleasant pictures. However, affective modulation of startle did not differ reliably between the two sides of probe presentation (sensory laterality) or the two sides of the response (motor laterality) in either study or in a combined analysis.
