Conventional text presentation styles for persons with aphasia include simple sans serif fonts, spacing modifications and picture inclusion to aid in comprehension. Recent studies have shown that use of a more visually complex Monotype Corsiva font has improved reading comprehension in dyslexic teens more than a simpler Ariel font (French, Blood, Bright, Futak, Grohmann, Hasthorpe & Tabor, 2013). This study presented portions of the reading comprehension subtests from four commonly used aphasia diagnostic tests in both the original font used (Ariel and Times New Roman) and in Monotype Corsiva. Ten adults with a diagnosis of aphasia completed a pretest questionnaire to gather personal attributes, and initially answered 20 reading comprehension questions randomly assigned in either original or experimental font, in version A or B. One week later the same participants completed 20 different reading comprehension questions in the 'untested' font and version and a posttest questionnaire to gather data on their testing experience and font preference. All spacing between letters, words, and lines of text remained constant when presenting items in the experimental font isolating the font style as the dependent variable. The response time for answering the 20 comprehension questions was recorded. Posttest questionnaire 'likeability' results revealed 70% of participants reported the original font easier to read; 50% stated they preferred the original font; and 20% believed they scored higher on the original font test version. However when using the experimental font participants' test scores improved overall by 7.8%; overall response time decreased by 4.2%; and 70% of participants achieved higher scores demonstrating a 15.2% increase in reading comprehension. A possible explanation for these results is that slightly harder-to-read fonts (such as Monotype Corsiva) require additional cognitive processing that increases the retention of material read by adults with aphasia.
