Abstract
AbstractIn the preceding Part 1, the effect of hue on impulsiveness and arousal was studied. From those results, yellow, red and orange were selected for further investigation since participants' performance was consistent with a low arousal state (high error rate and long response time) for the yellow background and high arousal state (low error rate and short response time) for the red background, whereas orange tended to result in high impulsiveness. This article will mainly investigate the fundamental theory of how chroma influences people's impulsiveness and arousal state. As in the previous article, the two main factors used to measure impulsiveness and arousal are also response time and error rate for each colored background. In the psychophysical experiment, participants were looking separately at backgrounds consisting of three hues (red, yellow and orange) with different chroma levels on screen to complete a range of psychometric tests. During the experiment, participants gave their response to the psychometric test as quickly and accurately as possible. From the results it can be seen that chroma has a significant influence on participants' response time and error rate, and influences impulsiveness and arousal. Gender difference will also be discussed in this article.
