Abstract
The present study aimed to develop a digital executive functioning test that measures visual concept formation and cognitive flexibility, the Visual Conceptualisation Test (VCT). The design and construction of the VCT was based on the Visual-Verbal Test (Feldman & Drasgow, 1981) and mental representation theories (e.g., Chandrasekaran & Narayanan, 1990; Collins & Quillian, 1969; Eysenck & Keane, 1995; Kosslyn, 1975; Rumelhart & Ortony, 1977). To evaluate the test, 23 males and 40 females ranging in age from 18 to 60 years old with 12 to 24 years of education completed all 50 provisional items of the test along with a number of other measures commonly utilised to assess executive functions. Principal component analysis supported that the test content measured analogical concept formation, visual spatial concept formation, and propositional concept formation. Two overall measures, total and single-hit scores were derived to measure visual concept formation and cognitive flexibility respectively. The resulting 30-item test had internal consistency of α = .64 that was comparable to other executive functioning measures in this provisional sample. Future research on the VCT’s validity, reliability, sensitivity and specificity with larger and more representative samples is needed along with examination of the validity of the various derived measures on the test in a variety of clinical settings.
