眨眼反射声探头，心率和主观报告进行了研究，在情感记忆的形象。36名大学生记忆了6对中性和恐惧性句子。在学会每一对之后，他们放松下来，听一系列统一的音调，每6秒一次。音调的变化（更高或更低）提示回忆两个句子中的一个。在第一个提示音，组（n= 12）在不同的指示：（a）忽略句子和放松，（B）默默地表达句子，（c）想象句子的内容作为一个个人的经验。在第二个提示音下，所有被试都进行了想象任务。惊吓探针（50毫秒，95分贝白色噪音）在放松和回忆试验中不可预测。探测眨眼反射更大，心率更快的恐惧句子回忆比中性句子回忆或放松。对于探测反射，这种效果是更大的图像比非语义回忆任务。（PsycInfo数据库记录（c）2022阿帕，保留所有权利）
Blink reflexes to acoustic probes, heart rate, and subjective reports were studied during affective memory imagery. Thirty-six undergraduates memorized 6 pairs of neutral and fearful sentences. After learning each pair, they relaxed and listened to a series of uniform tones, one every 6 sec. A change in tone pitch (higher or lower) cued recall of one of the two sentences. At the first cue tone, groups (n= 12) were under different instructions:(a) ignore the sentence and relax,(b) silently articulate the sentence, and (c) imagine the sentence content as a personal experience. At the second cue tone, all subjects performed the imagery task. Startle probes (50-msec, 95-dB white noise) were presented unpredictably during relaxation and recall trials. Probe blink reflexes were larger and cardiac rate faster at fear sentence recall than at neutral sentence recall or relaxation. For probe reflexes, this effect was greater for imagery than for nonsemantic recall tasks.(PsycInfo Database Record (c) 2022 APA, all rights reserved)
