The Avon Longitudinal Study of Parents and Children (ALSPAC) assessed their cohort members (CMs) at 18 months’ age (Children in Focus Clinic) using the Griffiths Scales of Mental Development (GSMD) Performance Scale.
Details on this measure and the data collected from the CMs are outlined in the table below.
| Year of data collection: | 1993-1994 | |
| Domain: | Non-verbal ability | |
| Measures: | Length estimation | |
| CHC: | Gv (Visual processing) | |
| Gp (Psychomotor abilities) | ||

| Administration method: | Trained interviewer; clinical setting; guided play session | |
| Procedure: | During a guided play session, the researcher presented the child with a series of boards and objects (insets) that could fit into shapes that were cut out of the boards. The researcher demonstrated how the insets fitted into the board, and the child was given the opportunity to copy. This was done with increased difficulty (increased number of holes and shapes in boards). | |
