Psychological Pleasure in Reading and Visual Cognition Under Colour Luminance: A Psycholinguistic Approach

Abstract

Purpose: To investigate the psychological pleasure of reading and visual cognition under two colour luminance.
Methods: A comparative study of sixty participants with emmetropia and no history of ocular pathology was conducted at Vision Sciences Laboratory, School of Medical Sciences, University of Hyderabad, Hyderabad, TS, India. Standardized Simple Measure of Gobbledygook (SMOG) index based readability passage was used as visual stimulus along with self paced reading task, obtained from the readability psycholinguistic software. This task was performed under white colour (Fluorescent light-400 lux) and orange colour luminance (Tungsten light-400 lux). Results: Significant results were obtained when the reading rate and speed, observed under white and orange colour luminance [p<0.001, X2=53.20], were compared. Comparison of reading errors also showed significant difference [p<0.001, X2=23.58], whereas positive correlation (r=+0.778) and psychological pleasure among both the groups observed under white luminance were 80% and 20% respectively. Conclusion: This study emphasized that psychological pleasure under colour luminance played an important role in reading performance and visual cognition.
