The Impact of Working Memory on the Mechanism of Theory of Mind in College Students with Hearing Impairment under Different Language Conditions
Theory of mind plays a crucial role in the academic achievement,interpersonal interactions,and social integration of individuals with hearing impairment(HI).However,the processing mechanism of theory of mind in HI remains unclear.This study employed a dual-task experimental paradigm to examine the impact of working memory on the mechanisms of theory of mind in HI.Participants were asked to complete theory of mind tasks using sign language and written language materials within a specified time while concurrently performing a working memory tasks.The results revealed that under"2+7"and"7+7"load conditions,HI failed to infer other people's mental states after processing written stories.They only failed under the"7+7"load conditions when inferring others'mental states after processing sign language stories.These findings indicate that sign language serves as a semantic compensation tool as the primary language code for reasoning about other people's mental states among HI under various cognitive load conditions.Furthermore,adjusting cognitive resources during semantic processing can effectively assist HI in reasoning and lead to favorable outcomes.
