The Developmental Effects of Stimulus Presentation Time on Primacy-Recencency.
Sarver, Gary Steven; Rasbury, Wiley C.
This study investigated the effects of stimulus presentation rate on primacy-recency effects in children. A modification of the Digit Span task used in the Binet and Wechsler intelligence scales provided the basic memory task administered to 56 male school children in grades kindergarten, second, fourth, and sixth. The specific design required children to verbally recall serial strings of digits presented at various rates of interdigit intervals. It was assumed that effective recall would be a function of general maturation and of the development of cognitive strategies. Age, delay, and age x delay were all significantly related to the number of digits correctly recalled. Results indicated that the traditional interpretation of the primacy effect as reflecting long-term memory store may not be valid. Rather, primacy effects may reflect differential encoding of material as a time-dependent process. (Author)
