The Effects of Symbol Format and Psycholinguistic Features on Receptive Syntax Outcomes of Children without Disability
Journal of Speech, Language, and Hearing Research, v65 n12 p4741-4760 Dec 2022
Purpose: The graphic symbol is the foundation of augmentative and alternative communication (AAC) for many preliterate individuals; however, research has focused primarily on static graphic symbol sequences despite mainstream commercial technologies such as animation. The goal of this study was to compare static and animated symbol sequences across receptive communication outcome measures and psycholinguistic features (e.g., word frequency). Method: A counterbalanced, 2 × 2 × 2 mixed design was used to investigate the effects of symbol format (animated and static), first condition (animated or static), and first experimental task (identification or labeling) on identification accuracy and labeling accuracy of graphic symbol sequences (five symbols) in 24 children with typical development ages 7 and 8 years old. Additionally, three 2 × 2 repeated-measures analyses of variance were conducted using symbol format (animated and static) and (a) word frequency (low, high), (b) imageability (low, high), and (c) concreteness (low, high). Results: In addition to superior identification and labeling accuracy of animated sequences, a significant interaction between symbol format and the first condition was observed for both experimental tasks. When the animation format was the first condition, then the children's performance improved in the subsequent static condition. Finally, word frequency, imageability, and concreteness ratings for all verbs and prepositions had significant effects on labeling accuracy of verbs and prepositions. Significant interactions between symbol format and psycholinguistic features were also found. For example, highly imageable, animated verbs were labeled with greater accuracy when compared with all other variables. Conclusions: Animation technology appears to alleviate some of the burden associated with word- and sentence-level outcomes in children with typical development. Moreover, animation appears to reduce the effects of psycholinguistic features such as word frequency and imageability by increasing the transparency of the symbol. Given the increase in research in this area, speech-language pathologists may consider adopting animated graphic symbols on a case-by-case basis as a tool to augment the learning of word classes in which movement is integral to comprehension.
