This investigation had a two-fold purpose. First, it attempted to determine if cognitively normal adults who were not familiar with Blissymbolics could reliably rate a sample of those symbols according to perceived complexity. Second, a correlational analysis was performed to determine if certain physical and/or semantic characteristics of the system could predict the complexity ratings. Thirty-one college students were instructed to rate 91 Blissymbols according to how complex they perceived the symbols to be. Four procedures were then used to determine the overall reliability of those ratings. Results indicated that the subjects could indeed make reliable ratings of perceived complexity. Next, the ratings were used as the dependent variable in a multiple regression analysis to determine if any of the seven physical and two semantic characteristics inherent in the system could serve as predictors of perceived complexity. The correlational analysis indicated that strokes and semanticelements were the best predictors. Implications for further research and for teaching symbols to nonspeaking individuals were discussed.
