| Administration method: | Teacher/psychologist/trained individual; face to face; pen and paper | |
| Procedure: | This test consisted of 40 verbal and 40 non-verbal items. For the verbal items, the children were presented with a list of four words that were associated either logically, semantically, or phonologically, and were asked to select the correct word (out of 5 options) to complete the series. For the non-verbal section, they were required to choose the correct shape/symbol. The overall testing session at age 11 lasted under 2 hours. | |
