Pan (23) found similar findings in his study on working memory and visual attention. In his study, participants were asked to identify whether the colour or the shape of the two objects that were presented were the same. In the first experiment, the colours of the two objects were the same but the shapes were different, while in the second experiment the conditions were reversed. The result showed that the participants’ response times were faster in identifying the differences in colours compared to differences in the shapes of the objects in both experimental conditions (23). This finding can be interpreted to show that colours have a better and greater ability to capture attention than other variables.
