The predator-prey model is widely used in various disciplines but not yet in psychology, where the competitive interactions featured in this model are actually not uncommon in behavioral data. This study attempts to introduce this model into psychology, using the relationship between food cravings and unhealthy snacking as an example. Self-efficacy, a determinant of health behavior, was used as a moderator of this relationship. Sixty female undergraduates completed a self-efficacy scale and a seven-day ecological momentary assessment in which they reported craving intensity and snack consumption five times per day. The results showed that food cravings stimulated subsequent snacking behaviors, and the lower the self-efficacy, the more likely people were to be driven by cravings. The act of snacking, in turn, eliminated the subsequent food craving, as if the act of snacking 'preyed' on the food craving. The predator-prey model reflects a simultaneous facilitation-inhibition-bidirectional relationship or negative feedback mechanism, which should have broader applications in behavioral science., Author(s): Xiaohui Luo [sup.1] , Yueqin Hu [sup.1] Author Affiliations: (1) https://ror.org/022k4wk35, grid.20513.35, 0000 0004 1789 9964, Faculty of Psychology, Beijing Normal University, , 19 Xinjiekouwai St, 100875, Beijing, China [...]
