Abstract  In everyday life, the speech of older people is more off-topic and verbose compared with young adults. The phenomenon is referred as the aging of off-topic verbosity (OTV). Pragmatic change hypothesis suggests that the change of communicative goals among the elders results in the increase of OTV. This hypothesis could explain the OTV induced by autobiographical topics, but not interpret that induced by non-autobiographical topics which does not involve change of communicative goals. Inhibition deficit theory proposes that OTV is closely related to the age-related decline in inhibiting irrelevant information, providing explanations for OTV on both autobiographical and non-autobiographical topics. However, this theory does not clearly clarify the ageing mechanism on OTV. Future research need focus on the underlying aging mechanism of OTV, so as to provide more effective intervention to resolve the social communication dilemma in older adults.
