Age differences in the associations between felt temperatures and color choices.

Thirty-six subjects, twelve each at 6, 12, and 18 years of age, were asked which of four colors (blue, green, yellow, or red) they were reminded of by each of four temperatures (containers at 4, 23, 35, or 45 deg C). More 18-year-olds than expected by chance made each of the conventional associations: hot/red, warm/yellow, cool/green, cold/blue. The 12-year-olds reliably made the hot/red association but none of the others. No more 6-year-olds than expected by chance made any of the conventional associations. The results suggest that the conventional associations are founded on a loosely held cultural norm rather than on an evolutionary or physiological basis.
