BCS70 – Age 10 – BAS Recall of Digits

Scoop.it ShareThis

The 1970 British Cohort Study (BCS70) assessed their cohort members (CMs) during the study’s age 10 sweep using the Recall of Digits measure from the British Ability Scales (BAS).

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

Domain:Short-term auditory memory
Measures:Short term auditory sequential recall:
  • Short-term auditory memory
  • Facility in verbal expression
  • Concentration and attention
  • Low scores:
  • Use of inappropriate strategies for storage or retrieval of numbers
  • CHC:Gsm (working memory)
    Administrative method:In school, administered by teacher
    Procedure:For each item the teacher read out digits and asked the child to repeat them. The exercise increased in difficulty from remembering and repeating two digits to three digits and then up to eight digits. If the child asked for a repeat of the numbers, this was scored as incorrect. The test was stopped after four consecutive incorrect responses.
    Duration: Total 30 minutes for 4 BAS tests
