The MRC National Survey of Health of Development (NSHD) assessed their cohort members (CMs) during the study’s age 8 sweep using the Picture Intelligence measure.
Details on this measure and the data collected from the CMs are outlined in the table below.
| Domain: | Non-verbal (reasoning) | |
| Measures: | Non-verbal ability |
|
| Induction | ||
| General sequential reasoning | ||
| CHC: | Gf (Fluid intelligence) | |
| Administration method: | Teacher/psychologist/trained individual; face to face; pen and paper | |
| Procedure: | This test was comprised of three sections. In section 1, participants were presented with 15 series, each consisting of 5 images (4 of which were conceptually similar), and were asked to select the ‘odd one out’. Section 2 consisted of 20 incomplete picture series, and participants were instructed to select, from 5 different options, the correct picture to complete each series. Section 3 included 25 conceptual similarity tasks. Participants were asked to choose, from 5 options, a picture that corresponded with an established rule, e.g. “foot is to shoe as head is to hat”. Each section was preceded by a practice trial. The overall testing session at age 8 lasted under 2 hours. | |
