The Creative Synthesis task devised by Finke and Slayton(1988) has been widely used as an experimental measure of mental synthesis, but previous studies have often failed to demonstrate any significant benefits of external support on participants performance.This paper discusses a study that examined novice and expert drawer's performance of synthesis using a modified stimul set that was designed to increase the load on visuo-spatial working memory. The results showed a significant increase in Transformational Complexity (Anderson & Hesltrup, 1993) of patterns produced by the expert groupwhile using sketching. It is argued that experts are more effective atusing sketching interactively to increase complexity, while novices relymore on using it as a simple memory aid.
