| Annotation | In a cross-sectional study of 164 participants aged 21 to 91, the authors examined age differences on two implicit tests, fragmented object identification (FOI) and category exemplar generation (CEG), and on tests of explicit memory, attention and verbal fluency. FOI results revealed impaired perceptual skill learning in those over 60, and a decrease in perceptual priming across young, middle-aged and older groups. CEG priming was impaired in those over 80. Regression analysis revealed explicit contamination of priming in both the FOI and CEG tests. Across the three implicit measures, age accounted for 4%-13% of the variance when explicit memory was controlled. Semantic fluency predicted CEG priming, suggesting possible frontal lobe involvement on the test. Altogether, results indicate that age has a small but reliable influence on implicit memory. (RH). |
