Hebb repetition learning tasks suitable for children and young people. One task uses pictures of common objects with associated verbal labels. The other task uses nonsense pictures without verbal labels. There are shorter and longer versions of each tasks, which enable task difficulty to be adapted to the participant's memory span level.

These tasks assess Hebb repetition learning, a form of long-term learning of serial order information over trials. They are based on short-term memory tasks and each one involves 16 trials. Eight of these trials present repeated 'Hebb' lists (exactly the same list is presented each time) and 8 of these trials are non-repeated 'filler' lists (the lists differ on every trial). Hebb and filler lists alternate throughout the task and are drawn from different item pools.
There are two Hebb repetition learning tasks.
1/ Verbal Hebb repetition learning task. Here the participant sees and hears a list of verbal items. The task combines simultaneous presentation of the image of each item (in the form of black and white line drawings) with the sound of that item's name being spoken.
2/ Visual Hebb repetition learning task. Here the participant sees a list of visual nonsense images that are illustrated as black and white line drawings - these images are not easily named.
Participants attempt to recall each list in correct order. Responses are via pointing to the list items in correct serial order on a response screen which shows the full pool of stimulus items in random order.
Within each task type, there are shorter and longer versions. There are also versions for a first testing session as well as a second testing session to assess test retest reliability. Please note that the preview button is not enabled for these materials.
