The Avon Longitudinal Study of Parents and Children (ALSPAC) assessed their cohort members (CMs) at 49 months’ age (Children in Focus Clinic) using the Information 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.
|Measures:||General verbal information|
|Oral production and fluency|
|CHC:||Gc (Crystallised intelligence)|
|Administration method:||Trained interviewer; clinical setting; child points to answer, answers orally|
|Procedure:||This test consisted of two parts. For the first part of the test, the child was presented with 6 sets of four images. For each set of images, the child was asked to point to a particular image (e.g. "can you point to the duck"). If the child did not point to the correct picture for the first item, the interviewer demonstrated. The second part of the test consisted of verbal items, in which the child was asked general knowledge questions, e.g. "show me your foot".|
