Question 1

What was their aim

Answer 1

Find out if capacity of phonological loop increases with age by using digit span as a measure of phonological capacity

Question 2

What was the procedure?

Answer 2

570 volunteers from Spanish schools age 5-17.
Divided into 5 age groups, average digit span recorded for each group.

They were read increasing sequences of digits and had to recall them in correct order, digits read at 1/s and digit lost increasing by one per sequence.

Question 3

Results

Answer 3

5 year olds have fairly low digit span and increases steadily to 11 then slows down and becomes stable. Suggests there is a developmental trend

Question 4

Conclusion

Answer 4

Digit span increases with age and develops when children sub vocalise. Spanish digit spans shorter than Anglo Saxon digit span due to length of Spanish words. Ageing affects digit span rather than dementia.
