Association Learning with Own- and Other-race Faces in three- and six-month old infants - A longitudinal study

Abstract

This longitudinal study assessed 133 Caucasian German infants at 3 and 6?months of age to investigate the influence of own-race and other-race faces as visual stimuli on association learning in the visual expectation paradigm (VExP). The study is related to the findings on the other-race-effect (ORE) which is said to emerge at 6months of age. Caucasian faces were used as stimuli of a familiar ethnic category, whereas African faces were used as stimuli of an unfamiliar ethnic category. There was no significant difference between the two stimulus classes in infants' reaction time (RT) to stimulus shifts at 3?months. At 6months of age, infants' RT decreased significantly in the Caucasian faces condition but not in the African faces condition. These results indicate that the processing of other-race versus own-race faces by the age of 6?months, which is also the relevant age for the onset of the ORE, has an important influence on the performance on the VExP.
