This paper describes conducted to further investigate the effects of color on cognition. Together, the experiments attempted to parse the previously observed effects of color. Experiment separated effects on cognitive discrimination, that is, the ability to recognize previously learned words, and response bias, the tendency to say that test words were previously learned. Participants performed tasks where they studied a list of words and then were asked to indicate whether each word was old or new within a set of words. The participants were randomly assigned to a word valence condition: pleasant, unpleasant, or neutral. All participants performed three conditions based on color: red, blue, and white. The primary hypothesis was that color would have an effect on both the discrimination of old words from new words and the response bias.
