Background: Augmented input (AI) refers to any visual or linguistic strategy used by communication partners to increase the message comprehension of a person with aphasia. Previous research has focused on the type of AI, such as high versus low context images and linguistic versus visual supports, that can be used to facilitate improved auditory and reading comprehension. The results of these studies have been varied. To date, researchers have not evaluated the frequency of AI required to improve auditory comprehension of persons with chronic aphasia. Aims: The purpose of this study was to determine the effect of AI using no context Picture Communication Symbols™ (PCS) images, presented at a frequency of 70%, versus no AI on the accuracy of auditory comprehension of narratives for persons with chronic aphasia. Methods and procedures: A total of 12 participants with chronic aphasia listened to two narratives, one in each of the conditions. Auditory comprehension was measured by assessing participants’ accuracy in responding to 15 multiple choice cloze-type statements related to the narratives. Results: Of the 12 participants, 7 participants (58.33%) gave more accurate responses to comprehension items in the AI condition, 4 participants (33.33%) gave more accurate responses in the no AI condition and 1 participant scored the same in both the conditions. Conclusion: No context Picture Communication Symbols™ (PCS) images used as AI improved the accuracy of responses to comprehension items based on narratives for some persons with chronic aphasia. Continued research is necessary in order to determine what forms and frequency of AI will lead to improved auditory comprehension for persons with aphasia. === Mini Dissertation (M(AAC))--University of Pretoria, 2017. === National Research Foundation (NRF) === Centre for Augmentative and Alternative Communication (CAAC) === M(AAC) === Unrestricted
