Abstract

In this study, we investigated the processes of coordination, adaptation, and calibration during the development of colour naming and colour constancy, and we tested whether colour term knowledge is related to colour constancy. We measured category membership and prototypes with 163 Munsell chips in preschool children (3- to 4-year-old) under neutral, green, and red illuminations, and compared their results to those of adults. We introduced an index of colour term maturity based on the similarity of children's colour term use to adults, and a colour category constancy index that quantifies the variation in colour categorisation that is specific to illumination changes. Results showed that illumination changes affected children's consistency of colour categorisation, but only to a small extent. However, colour term maturity and illumination-specific effects on consistency strongly varied in this age range. Correlations between colour term maturity and illumination-specific consistency indicated that colour constancy increases with colour term acquisition; but those results depended on the type of illumination changes (between neutral, green, and red). Together, our findings suggest that children progressively fine-tune and recalibrate the meaning of colour terms through processes of coordination and adaptation that are also involved in the calibration of colour constancy.
