先前的研究表明，食物匮乏会增强在呈现食物视觉暗示时产生的声学惊吓反射。果味无奖赏可能解释了这种效应，因为视觉食物暗示也被认为在食物匮乏时更有食欲和唤醒。然而，月经周期和性别对这一效应的影响尚不清楚，也不知道这种效应是否受到饥饿和进食动机的影响。根据一项研究内设计，20名处于不同月经周期阶段的健康女性和14名健康男性在正常和缺乏食物的条件下参加了两次实验。在18 h的食物剥夺后，听觉惊吓被食欲非食物的前景图片所减弱，但被食物图片的呈现所增强。月经周期阶段和性别之间没有差异。这种影响与饥饿的变化有关，这表明动机因素发挥了作用。
Previous research has shown that food deprivation enhances the acoustic startle reflex when it is elicited during presentation of visual food cues. Frustrative nonreward may explain this effect, since visual food cues are also rated to be more appetitive and arousing during food deprivation. However, the impact of menstrual cycle and sex on this effect remains unclear, and it is also not known whether this effect is influenced by hunger and motivation to eat. According to a within-study design, 20 healthy women in different menstrual cycle phases and 14 healthy men participated twice, in normal and food-deprived conditions. After 18 h of food deprivation, acoustic startle was attenuated by appetitive nonfood foreground pictures, but enhanced by presentation of food pictures. No differences between menstrual cycle phases and sexes appeared. The effect correlated with hunger changes, suggesting that motivational factors play a role.
