The Avon Longitudinal Study of Parents and Children (ALSPAC) assessed their cohort members (CMs) at 49 months’ age (Children in Focus Clinic) using the Arithmetic 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.
| Domain: | Arithmetic ability |
| Measures: | Numeric reasoning |
| Sequential processing | |
| CHC: | Gq (Quantitative Knowledge) |
| Administration method: | Trained interviewer; clinical setting; pointing; questions and answers delivered orally |
| Procedure: | The test contained 23 items. For items 1-7, the child was asked to point to an object that illustrated a particular quantitative characteristic on a visually presented array of objects. For items 8-11 the child demonstrated numeric knowledge by counting and manipulating blocks. For items 12-23, the child solved arithmetic problems that were read aloud by the interviewer. There was a time-limit for each of questions 12-23. If the child held up the correct number of fingers to indicate a numeric response, this was accepted. |
