The Avon Longitudinal Study of Parents and Children (ALSPAC) assessed their cohort members (CMs) during the study’s age 17.5 sweep (TeenFocus 4) using a measure of Behavioural Inhibition (Probability Learning And Reversal Task).
Details on this measure and the data collected from the CMs are outlined in the table below.
|CHC:||Gsm (Short-term memory)|
|Administration method:||Trained interviewer; clinical setting; CAPI|
|Procedure:||The participant had to learn a 'rule' (i.e. a red and a green grating pattern) that determined which of two abstract stimuli were selected. The rule changed in the middle of the block, and the goal was to see how quickly the participant could adapt to the rule change. All participants completed 40 trials of the initial rule, before the rule was reversed and a further 40 trials were administered.|
