%X The theory of processing recourses proposed that sensory function (SF), speed, capacity, and inhibition are four mediators that affect cognitive aging. Seldom has research examined the mediation of all these four factors. Standing on an integrating approach, the present study administered computerized measurements to test the mediators' influences on primary mental abilities (PMA) aging. 217 old adults from three communities of Beijing, with age ranging from 60 to 85, participated in the project. SEM analysis indicated that SF, speed, and capacity are important mediators for PMA aging. SF was a fundamental factor among the mediation for it affected the aging process through both speed and capacity. Capacity was a key factor in the hierarchical mediating model for all the indirect mediations connected with it. However, no significant mediation was found for inhibition when Stroop effect and negative priming were employed as the observing variables.
