Abstract/Summary Effective functioning in the world depends on detection of relations. Age-related differences in judgments of covariation have been previously demonstrated. Young and senior adults predicted plant growth in response to an amount of chemical, receiving feedback after each prediction. Between trials, young adults counted tones to strain working memory. The plantchemical relation changed halfway through the experiment (e.g. from a positive to negative correlation). Early exposure to a positive relation led to a preservative pattern in senior adults and young adults with the working memory task. Expectation may drive performance when previous trials are less likely to be maintained in working memory.
