According to the cognitive theory of social anxiety, the cognitive schema of people with social anxiety makes them easily attracted by threatening information and memory processing. Two experiments explored the social memory characteristics of college students with social anxiety. In Experiment 1, the study investigated the social memory bias of college students with social anxiety. In Experiment 2, cue word technology was used to investigate the social autobiographical memory amount and generalization degree of college students with social anxiety using cue words. The results showed that: (1) Compared with low social anxiety college students, college students with high social anxiety had a memory bias for negative social information, but did not have a negative memory bias for irrelevant social information; (2) Compared with low social anxiety college students, college students with high social anxiety had more negative social autobiographical memory; (3) Compared with low social anxiety college students, college students with high social anxiety have a higher degree of social autobiographical memory generalization. This study revealed that college students with high social anxiety had a negative memory bias toward social information, the amount of negative social autobiographical memory was larger and the degree of social autobiographical memory generalization was higher, providing new perspectives for future interventions in this population.
