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 Working Memory (N-back Task).
Details on this measure and the data collected from the CMs are outlined in the table below.
|CHC:||Short-Term Memory (Gsm)|
|Administration method:||Trained interviewer; clinical setting; CAPI|
|Procedure:||In the N-Back task, participants were presented with a sequence of stimuli one-by-one. They had to decide whether the current stimulus was the same as the one presented N trials ago. In this case, N was either 1, 2, or 3 trials. The higher the number, the more difficult the task. Visuospatial stimuli (letters and numbers) were used in the trials.|
