Abstract

This research is to examine the effectiveness of blue and yellow colour overlay on reading among the children with ASD. A quasi experiment pretest and posttest study were conducted between three groups where the children were divided into using blue coloured overlay, yellow coloured overlay and control group. T-test showed no significant difference between the two colours and the control group. However, Mean comparison showed highest mean for yellow, followed by blue and control group. The effect size was calculated using the formula of Cohen's d for yellow group and control group; blue group and control group respectively. The results are 0.53 for the yellow group and 0.57 for the blue group. Yellow overlay helped in achieving stable occlusion. Blue colour overlay has shorter wavelength showing moderate effect. The results showed promising effect of using coloured overlay as suggested by the theoretical review where the blue cone inhibit magnocellular neurones. It makes the letters to keep still instead of moving. The blue light research studies believed the blue wavelength were able to decrease the level of the melatonin secretion at night, which affected the suprachiasmatic clock and cause people to feel awake. Therefore the decreasing of melatonin level in the morning can increase the level of alertness.
