Development of chromatic induction in infancy

Abstract

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 uniformcolour 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 7month-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.

Infants Can't Discriminate the Orientation of a Grating Surrounded by an Oblique Square

“…However, the difference was not significant (w 2 2X43, ns). Also, the proportions of excluded participants were similar to those in previously reported habituation experiments with infants [eg Arterberry and Yonas (1988), 62.5%; Arterberry and Yonas (2000), 54.5%; Okamura et al (2007) experiment 1A, 41.8%; experiment 1B, 27.27%; experiment 2A, 33.3%; experiment 2B, 34.7%].…”

Young Children’s Color Preferences in the Interior Environment

“…In another recent study, the impact of environmental or surround color on color perception was investigated. The researchers found that color perception of 7-month-old infants was affected by environmental color (Okamura et al 2007). These studies shed light on the importance of color as a visual design element in children's environments.…”

Infants’ recognition of objects using canonical color

“…These results suggest that infants have trichromatic color vision by at least 4 months of age. Because of the development of low-level sensitivity to chromatic information as summarized above, most of the studies on infant color perception and cognition have examined infants over 5 months of age (e.g., Okamura, Kanazawa, & Yamaguchi, 2007). Considering this and the learning abilities during infancy as suggested by Reardon and Bushnell (1988), we hypothesized that the association between daily objects and their canonical colors emerges between 5 and 7 months of age.…”
