Mild cognitive impairment (MCI) refers to the transitional state between the cognitive changes of normal aging and the fully developed clinical features of dementia. Therefore examining the characteristics of MCI's cognitive impairments and corresponding neural correlates are of important theoretical and clinical significance for understanding, and further preventing and delaying the progress to dementia. Behavioral experiments were conducted by combination with neuroimaging techniques and neuopsychological measurements. We believed that binding is the key feature of episodic memory, that is binding features together makes episodic memory is the most Sofiscated memory form. Based upon this hypothesis, we examined MCI patients with emotional memory paradigm by adding emotional features to traditional neutral memory stimuli, and with prospective memory task by adding intention cues to promote future action with the content of future action. The results confirmed that the more "binding"-related tasks revealed more deficits in MCI relative to traditional item memory tasks; When there were no significant differences in terms of both RT and accuracy between MCI and normal controls in a match-to-sample task, dramatically differential event-related brain potential effects were observed in MCI group in contrast to norma
