The relationship between students' accuracy scores in identifying impossible figures and their drawing abilities judged by two visual artists on their performance in two CDAT drawing tasks was examined in relation to age and general spatial ability.
The house and the running-person drawing tasks adapted from CDAT were used in this study.
In addition to these self-report data, students also completed two 15-minute drawing tasks based on the CDAT tasks of drawing a house and a running person.
Moreover, for the two CDAT drawing tasks employed in this study, the scoring did not follow the standardized procedure.
