    Author: Tsai MJ.
    Journal: Res Dev Disabil; 2013 Oct; 34(10):3536-44. PubMed ID: 23962601.
    Abstract:
    The purpose of the study was to determine whether significantly different preference exists in typical adults between Picture Communication Symbols (PCSs) and Gus Communication Symbols (GCSs) frequently displayed on their AAC. A total of 56 participants participated in the study, including 15 participants in ages 20-35; 14 participants in ages 36-50; 13 participants in ages 51-60; and 14 participants in ages 66-80. Two tasks, an identification task and a preference task, were administered sequentially and individually. The results of this study suggest: (1) typical adults' preference between PCSs and GCSs did not show any significant difference; (2) the effect of age groups of typical adults did not have any significant effect on their preference between PCSs and GCSs. However, except the group of ages 51-65, the other three groups did consciously show their preferences for PCSs. Limitations and clinical implications of the current study have been concluded.
