Present project:

The purpose of the present study is to explore serial position effects, i.e primacy and recency, which are typically found in explicit memory tests, in implicit tests. Although a distinction between implicit and explicit memory stores has gained wide acceptance, alternative explanations of the pattern of dissociation between memory tasks have emerged, based on the level of processing at test, and study, and the degree of match between the cognitive processes required at test and at study. The present study will examine different types of implicit and explicit tasks, both of perceptual and conceptual character, and also the level of processing at encoding to evaluate whether it is the implicit/ explicit distinction or the level of processing at encoding, or test which is related to serial position effects.
