To explore the impact of resource scarcity on college students’ facial expression category perception and the underlying intervention mechanisms, Study 1 employed a facial expression category perception paradigm to compare the differences in turning points and slopes between resource-scarce and resource abundant groups.Building on the findings, Study 2 adopted a single-factor pretest-posttest experimental design with equivalent groups,implementing group psychological counseling intervention for the resource scarce group. The results revealed: (1)Compared to the resource-abundant group, the resource-scarce group shows significantly higher turning points and smaller slopes in discriminating anger-happiness expression continuum—indicating that resource scarcity leads individuals to adopt a more lenient criterion for judging negative facial expressions and exhibit weaker sensitivity to changes in expression categories;(2) The group counseling intervention reduces the negative effect of resource scarcity on individuals’ facial expression category perception. Overall, this study uncovers the mechanism through which resource scarcity undermines facial emotion recognition and demonstrate the buffer function of group counseling interventions, providing insights into social-cognitive biases under scarcity.
