“…Jaarsveld et al (2012) demonstrated that the CRT sub scores for intelligence and creativity correlated significantly with the Raven Progressive Matrices test (RPM, Raven et al, 1998) and the Test for Creative ThinkingDrawing Production (TCT-DP, Urban & Jellen, 1995), respectively. Importantly, the sub scores of the CRT did not show a relationship, although correlations between scores of RPM and TCT-DP were observed (Jaarsveld et al, 2012;Urban, 2005;Urban & Jellen, 1995). In addition to the above reported contrast, we note that intelligence in the CRT and RPM operates on an identical knowledge domain, namely, relationships among geometric components, but that intelligence in RPM and creativity in TCT-DP operate in different knowledge domains.…”
