Abstract
This study investigated the interface between ikonicand concrete symbolic functioning by studying two
different aspects of visual processing associated with mathematical problem solving. The first of these
involved the ·use of mathematically based visual. images' and diagrams, while the second was concerned
with incidental non-mathematical visual imagery associateq withthe problem story; Four groups ,of grade,
J 0 students were studied, representing all combinations of high and low concrete symbolic ability and
high and low ikonic ability. The results suggested that Success at problem solving was related to concrete
symbolic, but not in ikonic ability, and that the use of mathematically based visual images and diagrams
was similarly related to concrete symbolic rather than ikonic ability. Incidental visual imagery associated
with the problem story was, however, linked to individual differences in ikonic processing and was not
related to concrete symbolic functioning .
