The Avon Longitudinal Study of Parents and Children (ALSPAC) assessed their cohort members (CMs) at 49 months’ age (Children in Focus Clinic) using the Geometric Design 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.
|Fine-motor ability/finger dexterity|
|CHC:||Gv (Visual Processing)|
|Administration method:||Trained interviewer; clinical setting; pen and paper|
|Procedure:||The child was presented with a stimulus booklet, and pen and paper. The subtest contains two sections: i) first, they were asked to match a pictured design from an array of four designs (items 1-8 in picture booklet) and ii) they were required to copy a geometric figure from a printed model (items 9-16 in picture booklet). Encouragement (e.g. "do your best"), but no assistance, was provided. There was no fixed time limit for this subtest. The first 8 items were scored at one point each, the last eight items were worth 4 points for a total raw score of 57 points.|
