The perception of colour in an embedded field is affected by the surround colour. This phenomenon is known as chromatic induction. In the present study we investigated whether the colour perception by infants aged 5-7 months could be affected by the surround colour. In Experiments 1 and 2 each stimulus was composed of an array of six squares in tandem. The colour appearance of the array in the familiarization stimulus was established by chromatic induction. In Experiment 1 we used familiarization stimuli that were perceived as two-colour array with a two-colour surround. In Experiment 2 we used a familiarization stimulus that was perceived as a uniform-colour array with a two-colour surround. In the test phase, the uniform-colour array and the two-colour array were presented on a white uniform-colour surround in both experiments. The results showed that in Experiment 1 the 5- and 7-month-old infants had novelty preference for the uniform-colour test array. This suggested that the infants' colour perception could be affected by surround colour. The results of Experiment 2 showed that the 7-month-olds showed a novelty preference for the two-colour test array, but the 5-month-olds showed no novelty preference. This suggested that 7-month-olds' colour perception could be affected by surround colour, but that of 5-month-olds could not. We discuss the contradiction of the results between Experiments 1 and 2.
