This article focuses on the effects of color on memory encoding and retrieval in the classroom. The researchers set out to determine whether the color of the paper the material is studied on or the color of the paper the test is printed on has any effect on the encoding and retrieval of information. The researchers did this by conducting two experiments. In both experiments, participants were students enrolled in an undergraduate psychology course at Texas State University. Participants did this in exchange for extra course credit. In each experiment none of the participants were informed of the hypotheses until all the data had been collected. This blind process ensures that there will be no errors or interference with the study results. Participants in both experiments were asked to read a passage from The Holistic Guide to Canine Health. After being given the passage, participants had ten minutes to study the information. At the end of ten minutes they were given a short multiple choice test to complete in the next five minutes. This study aimed to determine whether certain colors can serve as cues for information retrieval. Student performance on the test was the dependent variable. The independent variable was the color of the paper on which the test or item was printed. This study demonstrated that test scores were higher for participants who read the passage on green paper, compared to those who read the passage on red paper (Martinez, Oberle & Thompson, 2010). In the first experiment, participants were randomly assigned to one of four groups. The first group read the passage on red paper and performed the test on red paper, the second group read the passage on red paper and performed the test on green paper, the third group read the passage on green paper and performed the test on green paper, and the last group read the passage on green paper and the test on red paper. The second experiment was done with all new participants. The same step and time limit for study and test time was used in this experiment. However in this experiment, participants were randomly assigned to five different groups. The groups represented the color of the paper the test was printed on: red, blue, green, yellow, and pink. The students were given the material on white paper and tested on the color group paper.
