Accuracy, efficiency and preferences of survivors of traumatic brain injury when using three organization strategies to retrieve words.
The primary objective was to compare the accuracy and preferences of adult survivors of traumatic brain injury (TBI) when using three organization strategies--semantic topic, geographic place and a word's first letter (alphabet)--to retrieve words using augmentative and alternative communication (AAC) technology. A repeated measures research design was employed. Twelve adult survivors of TBI ranging in age from 18-50 years participated in the study. These participants retrieved words using an AAC system organized using the three experimental conditions. In addition, they rank-ordered their preferences for each of the three strategies. Results showed that adults with TBI retrieve words more accurately and more efficiently when using the alphabet organization strategy than when using the topic or place strategies. Despite this, participants expressed a preference for using the topic strategy. Explanations for the findings and implications for AAC use are provided.
