另一种解释的惊吓探头调制的图片前景进行了测试：无论是反射幅度变化的功能，模态确定的注意力分配，或探头模态，反射幅度的变化与情绪效价的前景内容。36名受试者观看了一系列54张幻灯片，分为两个27张幻灯片。每个区块由三个独立评级的情感内容类别-愉快，中性和不愉快的九个样本组成。惊吓探针，一半视觉（闪光枪）和一半声学（白色噪音），在幻灯片演示期间和之间不可预测地呈现。眨眼反射，皱眉肌和眼轮匝肌肌张力，心率，皮肤电导记录在6秒的幻灯片间隔。受试者随后对幻灯片的情感效价和唤醒度以及兴趣值进行评级。还记录了自由观看时间。反射反应和所有辅助措施的分析支持的假设，惊吓调制的主要决定因素是前景内容的情感价。
Alternative interpretations of startle probe modulation by a pictorial foreground were tested: Either reflex amplitude varies as a function of modality-determined attention allocation, or regardles of probe modality, reflex amplitude varies with the emotional valence of the foreground content. Thirty-six subjects viewed a series of 54 slides, divided into two 27-slide blocks. Each block consisted of nine exemplars of three independently rated emotional content categories-pleasant, neutral, and unpleasant. Startle probes, half visual (flashgun) and half acoustic (white noise), were presented unpredictably during and between slide presentations. Eyeblink reflexes, corrugator and orbicularis oculi muscle tension, heart rate, and skin conductance were recorded during a 6-s slide interval. Subjects subsequently rated the slides for emotional valence and arousal, and interest value. Free-viewing times were also recorded. Analysis of reflex response and all ancillary measures supported the hypothesis that the primary determinant of startle modulation was the emotional valence of foreground content.
