What is it about?

People can learn to associate frequent occurrences of color and number categories without any awareness of their relationship. In our experiments, participants are asked to do a number-related task, without being told about the colors in which the numbers may appear.

Why is it important?

We replicate that color-association learning is better for the category of parity than for individual numbers, and extend this finding to magnitude, with potential interactions between parity- and magnitude-associated colors.

Perspectives

Category-level associations could be considered when designing the colors of number learning tools.
