当在观看图片期间呈现声学惊吓探头时，眨眼反射对于不愉快的前景刺激被增强，而在愉快的刺激期间被减弱。目前的实验评估了这样一种假设，即当图片被判断为更能唤起人的时候，这种情感-惊吓效应会增加。当受试者观看愉悦(愉悦、中性和不愉快)和唤醒(低、中、高)不同的图片时，记录了由三种不同强度的惊吓探头引起的眨眼。唤醒程度高的图片内容，在不愉快内容时的眨眼增强和在愉快内容时的眨眼减少都明显最强。所有被测试的探头强度都存在这种影响。
When acoustic startle probes are presented during picture viewing, the blink reflex is augmented for unpleasant foreground stimuli and reduced during pleasant stimuli. The present experiment assessed the hypothesis that this affect-startle effect increases as pictures are judged to be more arousing. Eyeblinks elicited by startle probes of three different intensities were recorded while subjects viewed pictures varying in both pleasure (pleasant, neutral, and unpleasant) and arousal(low, moderate, and high). Both blink potentiation during unpleasant content and blink diminution during pleasant content were clearly strongest for picture contents high in arousal. The effect was present for all probe intensities tested.
