Abstract:

Background: Recent studies have reported that infants can form explicit-like-memories well before their first birthday. These findings raises questions about how early memory processes are connected to other early abilities as well as to later cognitive functioning. In the present longitudinal study, early recall memory, recognition memory and social communication skills are investigated in parallel. The main aim being to explore how these different measures relate to both language and cognition.
Method: Thirty typically developing Swedish children were observed at 6, 9, 14 and 50 months of age. Visual recognition memory was tested at 6 months recall memory (=deferred imitation) at 9 months, social communication skills (joint attention, requesting and turn taking) at 14 months and language (gestural communication and vocal comprehension) also at 14 months. Finally, an evaluation of general cognitive abilities (the McCarthy test) was carried out at 50 months.
Results (A) Predicting communication skills at 14 months: A regression model built on visual recognition memory, deferred imitation and turn taking significantly predicted gestural communication at 14 months (adj. R2 = .41, p < .01). Deferred imitation and turn taking also displayed strong individual correlations with gestural communication although the strongest observed relationship was noted when they both were combined as in the regression analysis.
Results (B) Predicting cognition at 50 months: The impact of infant performance on cognition at 50 months was investigated by dividing the children according to their performance on deferred imitation and joint attention. This resulted in four groups; high on both variables, low on both variables and the two cross-pairings. The group with a combined low performance on both infancy measures differed from the other children. This group (n = 8) obtained a lower score on the cognitive test compared to the other children (n = 18; t(26) = -3.54, p < .005).
Discussion: The results from this longitudinal study suggest that early signs of recall memory as measured with the deferred imitation paradigm are related to both early communication skills and later cognitive abilities. The strong regression model and the weak cognitive performance of the low-low performance group in infancy suggest that it is beneficial to look at recall memory and social communication in combination in order to achieve a better understanding of how early and later development hangs together. |
