Study: NCT04905797

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.

Intervention type: DIAGNOSTIC_TEST
Intervention: Cambridge Gambling Task Test
Description: 1. The proportion (0 - 1) of all trials where the subject chose the majority box color. Calculated over all assessed trials from both the ascending and descending conditions in which the number of boxes of each color differed.~2. Risk adjustment is a measure of sensitivity to risk, based on the ability to modify choices in the light of information about the probability of different outcomes and to track the optimal outcome on eaeh trial. The measure is calculated from the average proportion of points that the subject ehose to bet with, taking into aeeount the number of colored boxes in the majority.~3. Allows for the dissociation between risk taking and impulsivity by determining whether subjects simply just place a bet at the first opportunity. Calculated as CGT Risk Taking for all trials from the descending condition minus CGT Risk Taking for all trials from the ascending condition.
