Scoop.it ShareThis

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 Spelling Task.

Details on this measure and the data collected from the CMs are outlined in the table below.


Domain:Verbal ability (spelling)
Measures:Spelling ability
CHC:Grw (Reading/Writing)
Administration method:Trained interviewer; clinical setting; pen and paper
Procedure:Based on a pilot study of several hundred children (Peter Bryant and Terezinha Nunes, Personal Communication). The interviewer asked the child to spell 15 words, both regular and irregular, that increased in difficulty. For each word, the interviewer i) read it aloud, and ii) used it in a sentence. The child was asked to write down the correct spelling of the word.
