The digit span test measures working memory and is taken from the Wechsler Adult Intelligence Scale IV. In the test participants must repeat a sequence of digits. Sequences are repeated at increasing length until the participant makes two errors at the same length. The test comprises two parts. In the first, participants repeat sequences is the order given; in the second they repeat sequences in reverse order. This outcome measure takes the total correct responses in reverse order. Sequence lengths are between two and seven digits, with to sequences of each length, giving a maximum score of 12.

The PAL task measures participants' ability to associate two items of information in memory. In this study, participants must learn a set of ten objects and their associated locations. The recognition score is the number of correct choices when given two possible locations for a given object. Each object is tested three times, giving a maximum score of 30.

The recall score measures participants ability to recall which object was present at each location (a maximum of 10).

The PDP is a word memory test. Participants first read out loud a set of words. They are then presented with incomplete words and must fill in the missing letters. In one part of the test, participants must use one of the remembered words whenever possible. In the other part of the test, they must avoid the remembered words. The two parts are designed to dissociate two types of memory: familiarity and recollection. Familiarity is the unconscious remembering of a word because it was previously seen, which is an advantage when including the words, but a disadvantage when avoiding them. Recollection is the conscious remembering of a word and the context where it was encountered. This is an advantage in both parts of the test. The scores in each part of the test are combined to compute scores for familiarity and recollection, each in percent.
