The tests were given under two conditions: Timed, Untimed.

One-hundred twenty-six participants with and without LD (72 female, 54 male) participated in this study. Participants were undergraduate, graduate, and non-students, ranging in age from 20 to 56.

Two tests were used: Graduate Record Examination (GRE) General Test, Nelson-Denny Reading Test.

Results indicated no significant effect on test performance between ability groups (LD and non-LD) on the GRE. Timed scores for the students with LD were significantly lower than for the students without LD. Also, test scores increased significantly for both groups between timed and untimed testing conditions.
