The Avon Longitudinal Study of Parents and Children (ALSPAC) assessed their cohort members (CMs) during the study’s age 7.5 sweep (Focus@7) using the Phoneme Deletion Task.
Details on this measure and the data collected from the CMs are outlined in the table below.
| Domain: | Verbal ability (language repetition) |
| Measures: | Spelling ability |
| Oral production and fluency | |
| Communication ability | |
| CHC: | Gc (Crystallised Intelligence) |
| Grw (Reading/Writing) | |
| Administration method: | Trained interviewer; clinical setting; answers orally |
| Procedure: | Children were presented with a word, and then asked to repeat the word, and then say it again with part of the word missing, e.g. 'sour' without the 's' = 'our'. The task began with 2 practice trials, followed by 40 test trials, each of which increased in difficulty. The number of correctly spoken items was recorded. |
