The relationship between the reflection-impulsivity dimension of cognitive style and susceptibility to the Mueller Lyer illusion was investigated in nine year old children. Forty-four subjects, classified as either impulsive or reflective on the Matching Familiar Figures Test, were presented the Mueller Lyer figure under two viewing conditions, unrestricted exposure time and restricted exposure time of .1 second. It was expected that reflective children would be less susceptible to this illusion under the unrestricted condition than the impulsive children. Less difference between reflective and impulsive children was expected when exposure time was restricted. Results confirmed earlier studies that restricted exposure time increased the magnitude of the illusion, but failed to confirm the relationship between cognitive reflection-impulsivity and susceptibility to the illusion.
