ALSPAC – Age 8.5 – WISC-III Block Design ShareThis

The Avon Longitudinal Study of Parents and Children (ALSPAC) assessed their cohort members (CMs) during the study’s age 8.5 (Focus@8) sweep using the Block Design measure from the Wechsler Intelligence Scale for Children (WISC-III).

Details on this measure and the data collected from the CMs are outlined in the table below.

Domain:Non-verbal ability
Spatial visualisation
Visual motor coordination
Simultaneous processing
Synthesis (part-whole relationships)
Non-verbal concept formation
CHC:Gs (Processing Speed)
Gv (Visual Processing)
Administration method:Trained interviewer; clinical setting; physical task
Procedure:The child was presented with an image or model that depicted a pattern, and was tasked with recreating the pattern with one- and two-colour blocks (white and red). The test contained 14 designs, and the child was allowed two attempts at each design. Points were awarded for completion, and bonus points were awarded based on time
