Recognition memory development in two- to four-year-olds.

Tested 32 preschool children on 2 36-item recognition lists. 8 boys and 8 girls were in each of 2 age groups; mean ages of the 2 groups were 4 yrs and 2 yrs 11 mo. No sex differences were observed. The younger Ss responded correctly 81% of the time, and the older Ss 92% of the time. A signal detection analysis revealed that this developmental difference was due to retention components, not decision components. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
