Primacy Effects in Nonspatial Recognition Memory in Rats
The existence of primacy and recency effects in nonspatial recognition memory in rats was investigated using a nonmatching-to-sample task (namely, visual discrimination in a Y-maze). Although previous research has demonstrated recency effects in nonspatial tasks, evidence for a primacy effect in such tasks is equivocal. The current study evaluated nonspatial memory under conditions that have been found to optimize primacy effects. Significant primacy effects were found over all trials and also for the last six trials. Results are discussed in terms of identification of the optimal conditions for producing and detecting serial position effects in memory. (C) 2000 Academic Press.
