Carroll, Mark (2015) The Visual Conceptualisation Test: Measuring Executive Function Through the Assessment of Concept Formation and Cognitive Flexibility. Honours thesis, University of Southern Queensland. (Unpublished)
Abstract
The Visual Conceptualisation Test (VCT) was conceived in 2013, in order to update the Visual Verbal Test (VVT), which was originally published in 1957. The original design of the VCT provided a measure of executive function through the assessment of visual concept formation and cognitive flexibility. To evaluate the psychometric properties of the test and the underlying structure, a 30 item version of the VCT was administered to 183 healthy male and female Australians aged between 18 and 74 years, and across a range of education levels. Principal component analysis was conducted at an item category level to examine the presence of constructs reflecting analogical, visual spatial, and propositional concept formation. The internal consistency of the test proved to be lower than expected, however an underlying construct, representing visual spatial concept formation, was replicated from the original design study, which suggested that the VCT may provide a unique measure of executive function. There were no significant effects of gender, age, or education on the VCT performance scores, and normative data for an Australian adult population was developed for concept formation and cognitive flexibility measures, along with an updated scoring system. The VCT has great potential to be included as a standard test used by clinicians to assess executive function and it is well suited for patients with limited verbal or motor co-ordination abilities. Future research should focus on the collection of data in a clinical setting.
