Learning Multiple Lists at the Same Time in the Hebb Repetition Effect

In short-term ordered recall, when 1 list of items is repeated over the course of the experiment, recall performance typically improves. This is known as the Hebb repetition effect (Hebb, 1961). In the present study, we contrasted the typical condition involving a single repeated sequence with concurrent learning of 2 repeated sequences. Participants performed a spatial recall task, in which sequences of 7 dots were presented in each trial. For …
