The Effects of Structural Complexity on Age-Related Deficits in Implicit Probabilistic Sequence Learning

Objective. The primary objective was to determine whether age deficits in implicit sequence learning occur not only for second-order probabilistic regularities (event n − 2 predicts n), as reported earlier, but also for first-order regularities (event n − 1 predicts event n). A secondary goal was to determine whether age differences in learning vary with level of structure.
