The Avon Longitudinal Study of Parents and Children (ALSPAC) assessed their cohort members (CMs) during the study’s age 9 sweep (Focus@9) using the Sentence Decision Task.
Details on this measure and the data collected from the CMs are outlined in the table below.
|Measures:||General (verbal) information comprehension|
|CHC:||Crystallized intelligence (Gc)|
|Administration method:||Trained interviewer; clinical setting; pen and paper|
|Procedure:||Administered primarily to children who greatly struggled with the NARA II. Children were presented with a series of 39 sentences, some of them describing something that is true (e.g. "Birds have wings") and some of them describing things that are false (e.g. "Birds wear shoes"). The child was asked to read the sentence and indicate with a tick or a cross if they felt that the sentence was true or false. The child was shown two examples that had already been completed and was then given a further four as practice trials.|
