Abstract: | Researchers have argued for age deficits in learning about the effects of encoding strategies from task experience, partly on the basis of absolute accuracy of metacognitive judgments. However, these findings could be attributed to factors other than age differences in learning. Forty older and 40 younger adults participated in 2 study-test trials in which they studied paired associates with imagery or repetition, predicted recall for the items, attempted recall, and postdicted recall. Recall was greater after imagery than repetition, yet this effect was not fully reflected by predictions made on Trial 1. Although both older and younger adults accurately postdicted recall from Trial 1, absolute accuracy of the predictions made on Trial 2 showed little improvement. By contrast, both age groups demonstrated increases in between-person correlations of predictions with recall, which is inconsistent with age deficits in knowledge updating. Thus, both older and younger adults had updated knowledge about the relative effects of the strategies, but such updating was not evident in the absolute accuracy of the predictions. |
