Intervention type: DIAGNOSTIC_TEST
Intervention: Stop Signal Task (CANTAB)
Description: The estimate of time where an individual can successfully inhibit their responses 50% of the time.

Intervention type: DIAGNOSTIC_TEST
Intervention: Intra-Extra Dimensional Set Shift (CANTAB)
Description: 1. The number of trials for which the outcome was an incorrect response (subject pressed the incorrect button within the response window), calculated across all assessed trials.~2. The total number of times that the subject chose a wrong stimulus - i.e. one incompatible with the current rule, adjustment for every stage that was not reached.

Intervention: Spatial Working Memory Test (CANTAB)
Description: 1. The number of times the subject incorrectly revisits a box in which a token has previously been found. Calculated across all assessed four, six and eight token trials.~2. The number of times a subject begins a new search pattem from the same box they started with previously. If they always begin a search from the same starting point, we infer that the subject is employing a planned strategy for finding the tokens. Therefore, a low score indicates high strategy use (1 = they always begin the search from the same box), a high score indicates that they are beginning their searches from many different boxes. Calculated across assessed trials with 6 tokens or more.

Intervention type: DIAGNOSTIC_TEST
Intervention: Multitasking Test (CANTAB)
Description: 1. The number of trials for which the outcome was an incorrect response.~2. The median latency of response (from stimulus appearance to button press). Calculated across all correct, assessed trials.~3. The difference between the median latency of response on the trials that were congruent versus the trials that were incongruent. A positive score indicates that the subject is faster on congruent trials and a negative score indicates that the subject is faster on incongruent trials. A higher incongruency cost indicates that the subjects take longer to process conflicting information.~4. The difference between the median latency of response during assessed blocks in which both rules are used versus assessed blocks in which only a single rule is used. A positive score indicates that the subject responds more slowly during multitasking blocks and indicates a higher cost of managing multiple sources of information.
