Combined effects of Attentional load and Colors on word processing speed in both cerebral cortexes

Abstract

The current study aimed to study the combined effects of Perceptual load and Color on the speed of word processing in the left and right hemispheres. The study sample consisted of 102 university students )51 female(. All participants were right-handed and have normal or corrected vision. This study used Factorial design, which includes the Following factors: Perceptual load, Colors, Words and Cerebral cortex )Right vs. Left( hemisphere. The results showed that there is main effect of Perceptual load with increasing the reaction times. In addition, there is main effect of colors and interactions of Colors and perceptual load on the processing of Arabic words. This study increased our understanding about how the human brain perceives different stimuli with different colors.
