Participants were presented with an acoustic startle probe while they smelled either a pleasant odor or an unpleasant odor (n = 40 per condition). Within each condition, participants were presented with four blocks in which odor was present and four in which odor was not present (no-odor control). Significant differences were found in both conditions between the odor and no-odor blocks. In the unpleasant odor condition, blink magnitude was greater during the odor blocks; in the pleasant odor condition, blink magnitude was smaller during the odor blocks.
研究人员让参与者在闻宜人气味或难闻气味时接受听觉惊吓探测（每种情况各40名参与者）。在每种情况下，向参与者展示四个有气味的组块和四个无气味的组块（无气味对照）。在两种情况下，有气味组块和无气味组块之间均发现了显著差异。在难闻气味情况下，气味组块期间眨眼幅度更大；在宜人气味情况下，气味组块期间眨眼幅度更小。
