摘要: Implicit memory was measured using word fragment completion up to 18 months after being exposed words multiple times. In all cases participants showed significant priming for multiply presented over singly ones. shorter delay conditions (up 6 weeks), implicit tested reading speed and completion. Both measures indicated larger effects following prior exposures than a single exposure. This effect greater low- high-frequency words. These results are consistent with the view that is part of same system produces explicit memory. They do not support claims dissociations in repetitions on had been used argue separate systems. recent years, distinction between memories has taken place among diverse dichotomies partition into comprehensible pieces. The term “implicit memory” first introduced by Graf Schacter (1985) refer improved performance due previous experiences does require conscious recollection those (Schacter, 1987), whereas contrasting term, “explicit memory,” refers experience recollection. implicit/explicit gains its primary interest degree two phenomena can be independently manipulated. For example, amnesics generally demonstrate devastating loss memory, tests show improvements past exposure indicating that, indeed, some memorial processes spared (e.g., & Schacter, 1985; Shimamura, 1986).
