Scoop.it ShareThis

The 1970 British Cohort Study (BCS70) assessed their cohort members (CMs) during the study’s age 46-47 sweep using the Verbal Fluency (Animal Naming) Test.

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


Domain:Verbal fluency
Measures:Verbal/semantic fluency
Executive function
CHC:Glr (Long-Term Storage and Retrieval)
Administration method:Trained interviewer; CAPI
Procedure:Participants were asked to name as many different animals as possible within a one-minute timeframe. The interviewer made a note of each named animal and entered the total number into the CAPI programme. Repetitions, named animals (e.g. Bambi), and redundancies (e.g. white cat, black cat) were not included in the total score.
