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.
|Visual motor coordination|
|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|

|Scoring:||Raw scores were converted into scale scores using tables provided in the WISC manual (M = 10, SD = 3).|
|Item-level variable(s):||Not readily available|
|Total score/derived variable(s):||f8ws029 - f8ws059|
|Descriptives:||Raw score||Scaled score|
|N = 7,324||N = 7,362|

|Mean = 32.19||Mean = 10.53|
