The present research examined the effects of message selection techniques and array sizes on short-term visual memory. Specifically, this study investigated whether there are short-term visual memory differences between direct selection and the row-column scanning in normally developing 4-year-old children. Results suggested a significant difference in favor of direct selection over scanning for the array with 40 symbols. The other purpose of this investigation was to determine whether differences existed as a function of the number of symbols available on the communication aid. The effect of array size upon memory did reveal a significant difference between the array with 30 symbols and the array with 40 symbols.
