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.
|CHC:||Crystallised intelligence (Gc)|
|Fluid intelligence (Gf)|
|Visual processing (Gv)|
|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.|
|Item-level variable(s):||Not readily available|
|Total score/derived variable(s):||f8ws028 - f8ws058|
|Descriptives:||Raw score||Scaled score|
|N = 7,308||N = 7,309|
|Range = 0 - 58||Range = 1 - 19|
|Mean = 20.12||Mean = 9.41|
|SD = 10.74||SD = 4.77|

|Age of participants:||Mean = 103.82 months, SD = 3.92, Range = 89-127|
|Other sweep and/or cohort:||None|
