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 Picture Arrangement 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.

| Administration method: | Trained interviewer; clinical setting; physical task | |
| Procedure: | The child was presented with a set of cartoon images and was asked to arrange them in an order that made a sensible story. A sample item was administered prior to the full trial, which consisted of 14 sequences. Two trials were given for the first two items. For item 1 only, the examiner demonstrated the correct sequence if the child failed to do so. | |

| Scoring: | Items 2 - 4 were worth 2 points each, with bonus points for completion time for items 3 - 14. Raw scores were converted into standardised scores (M = 10, SD = 3) using the WISC manual. | |
