| Administration method: | Teacher/psychologist/trained individual; face to face; read aloud | |
| Procedure: | After the participant completed the word reading task, the interviewer asked the child whether they knew the meaning of each word, e.g. "What is a ___", "What do we mean by ___". The interviewer noted the number of correct responses. The overall testing session at age 11 lasted under 2 hours. | |
