Abstract
The purpose of this study was to explore the influence of environmental colour on people’s lateral and logical abilities. This was done by evaluating study participants’ response time and error rate when completing six types of psychometric tests that were performed in various hue backgrounds on a computer. To maximise the colour stimulation provided by the monitor, the experiment was carried out in a dark laboratory. Analysis of participants’ response time and error rate showed that different colours could significantly influence arousal and impulsiveness, which suggests that colour has indirect impacts on cognitive abilities. Further analysis revealed that different colours had various effects depending on the type of psychometric test given. These findings suggest that future research on environmental design should consider how to effectively use colour to impact people’s performance and behaviour.
Highlights
The human brain divides into two distinct cerebral hemispheres, and each of them tends to lateralise and specialise in different cognitive abilities [1,2,3]
The right hemisphere is responsible for lateral abilities, while the left hemisphere is in charge of logical abilities [4,5,6,7]
Together with response time and error rate (Figure 6c), we found purple, backgrounds
Summary
The study evaluated the influence of colour stimuli on people’s cognitive abilities with particular focus on logical and lateral abilities. The right hemisphere is responsible for lateral abilities (i.e., creative thinking, imagination, holistic perception and emotional thought), while the left hemisphere is in charge of logical abilities (i.e., analytical thought, detail-oriented perception, ordered sequencing, rational thought, and math/science) [4,5,6,7]. Colour and light as a ubiquitous perceptual stimulus have been manifested in the previous studies in optimistically affecting people’s cognitive functions [8], human perceptions [9], psychological and emotional reactions and [10,11], behavioural intentions [12]. Research investigating the influence of colour stimuli on people’s lateral and logical abilities is limited. Questions that this study deems significant and attempts to answer are (1)
