Colour and emotion: children also associate red with negative valence

The association of colour with emotion constitutes a growing field of research, as it can affect how humans process their environment. Although there has been increasing interest in the association of red with negative valence in adults, little is known about how it develops. We therefore tested the red-negative association in children for the first time. Children aged 5-10 years performed a face categorization task in the form of a card-sorting task. They had to judge whether ambiguous faces shown against three different colour backgrounds (red, grey, green) seemed to 'feel good' or 'feel bad'. Results of logistic mixed models showed that - as previously demonstrated in adults - children across the age range provided significantly more 'feel bad' responses when the faces were given a red background. This finding is discussed in relation to colour-emotion association theories.
