The Avon Longitudinal Study of Parents and Children (ALSPAC) assessed their cohort members (CMs) at 49 months’ age (Children in Focus Clinic) using the Mazes measure from the Wechsler Preschool and Primary Scale of Intelligence Revised (WPPSI-RUK).
Details on this measure and the data collected from the CMs are outlined in the table below.
|CHC:||Gv (Visual processing)|
|Administration method:||Trained interviewer; clinical setting; pen and paper|
|Procedure:||The child was presented with a series of mazes, and instructed to draw a pathway to the centre of each maze. For the first two mazes, the interviewer demonstrated by drawing half of the line. When necessary, the interviewer made use of several prompts to encourage the child to complete the mazes.|
