Presentation by order of difficulty of test tasks to persons with aphasia.

To determine the effects of arranging test tasks by order of difficulty, two test forms were administered to each of 20 patients with aphasia. The two test forms were split halves of the Porch Index of Communicative Ability. One of the test forms, Form EH, was presented to each patient with the subtests arranged for the individual subject in an order from easy to hard. The other test form, Form HE, was administered to each subject in the hard-to-easy order. There was no significant difference between the performance of the subjects on the Form EH and their performance on Form HE.
