Measures of procedural and declarative memory were administered to 88
children forming two groups, aged 8 and 12. Two measures of priming, G
ollin Figures and Degraded Words, were compared to declarative measure
s of recall. Strong support for a developmental dissociation between p
riming tasks and declarative memory was found. Both age groups showed
a similar amount of priming facilitation, yet a significant age effect
was observed for the declarative recall tasks. Current findings demon
strate that the level of procedural memory performance stabilizes duri
ng a period of development when declarative memory continues to improv
