Young Children

The authors developed developmentally appropriate symbols (DAS) based on children’s interpretations of 10 abstract early language concepts; all gone, big, come, eat, more, open, up, want, what and who.

They compared the abilities of typically developing, preschool children to identify the DAS symbols to the same concepts represented by Picture Communication Symbols (PCS) which are based on adult understanding of the concepts. They also investigated whether the children preferred one type of symbol over the other and why.

In the symbols identification task the children were 82% accurate with the DAS set and 58% with PCS. All items in the DAS group scored more highly except ‘who’ which was identified correctly by equal numbers of children in both groups.

The DAS symbols had consistently higher correct selections across all three word categories used; action words, descriptors and questions.

In choosing preferences for symbols sets there was no significant difference between the two, though higher numbers selected DAS.
