Newborns' Memory Processes: A Study on the Effects of Retroactive Interference and Repetition Priming

Newborns' memory abilities have been shown in a number of studies. Yet little is known about whether many of the factors that are known to affect encoding, storage, and retrieval in older children and adults are also integral to memory processes at birth. Here we tested for the presence at birth of the retroactive interference and repetition priming effects using the visual paired comparison paradigm. Newborns' memory performance on a visual recognition task was prevented by the interposition of a distractor stimulus between the habituation and the test phase (retroactive interference, Experiment 1). However, forgetting was offset by further brief exposure to the familiar stimulus (repetition priming, Experiments 2 and 3).
