In a single large-scale study, we demonstrate that verbal sequence learning as studied using the classic Hebb repetition effect (Hebb, 1961)--the improvement in the serial recall of a repeating sequence compared to nonrepeated sequences--is resilient to both wide and irregular spacing between sequence repetitions. Learning of a repeated sequence…

In the present study, the authors offer a window onto the mechanisms that drive the Hebb repetition effect through the analysis of eye movement and recall performance. In a spatial serial recall task in which sequences of dots are to be remembered in order, when one particular series is repeated every 4 trials, memory performance markedly improves…
