Two experiments examined the relation of working memory capacity and the inhibition mechanism in working memory. Experiment 1 demonstrated that the high WM span group inhibited irrelevant information selectively and the low WM span group maintained both relevant and irrelevant information within WM. Experiment 2 showed that there were similar patterns of response time between high and low WM span groups in the lexical decision task. These results suggest that the ability to maintain relevant information and inhibit irrelevant information selectively in WM is an important factor of individual differences in working memory.
