Objectives: The purpose of this study is to examine the effects of iconicity and cultural background on the recognition of social word AAC (augmentative and alternative communication) graphic symbols between two cultural groups.
Methods: The participants of the study were 48 undergraduate students (24 Koreans and 24 Americans), and 20 graphic symbols of 10 social words were selected for the stimuli from PCS and Ewha-AAC symbols developed in Korea. The transparency task asked the participants to guess and write down the meanings in 30 seconds for each symbol. For the translucency task, the participants marked their degree of agreement with the meaning of the symbol on the 5-point rating scale, given 20 seconds for each slide.
Results: First, the Korean students guessed the meanings of social word AAC symbols more correctly than the American students in Ewha-AAC symbols. Second, the Korean students gave higher scores to Ewha-AAC symbols, while the American students gave higher points to PCS. Third, there were moderate and positive correlations between the performances of the iconicity tasks.
Conclusion: The results suggest that cultural background of words, symbols can be influencing factors for the recognition of graphic symbols. In addition, the positive correlations between the performances of the iconicity tasks suggest that transparency and translucency of graphic symbols may affect the symbol recognition. Moreover, the results suggest the need to consider the degree of transparency and translucency of graphic symbols when selecting symbols for AAC.
