Colombo, John; Richman, W. Allen; Shaddy, D. Jill; Greenhoot, Andrea Follmer; Maikranz, Julie M. – Child Development, 2001
Presented paired-comparison familiarization-novelty recognition task to 4-month-olds. Found that peak look duration during pretest and familiarization periods predicted recognition performance. Recognition was unaffected by choice-trial length. Longer gaze durations during pretest and familiarization were associated with more time in heart…

Examined effect of familiarization on 3.5-month-olds' retention of visual stimuli with varying delay times. Found support for retention models in which direction of attentional preferences (novel, familiar, or null) depends on memory accessibility. Short lookers showed better retention over time than long lookers, indicating that much of the…
