Enthusiasm for developing creativity in the individual has been remarkably widespread - at least in America - over the past twenty-five years or so. The armed services, the arts and sciences, educational institutions, businesses and industries are recognising to a greater and greater extent, the urgent necessity of developing this relatively neglected aspect of people is personalities. Their reasons differ, of course, and usually the welfare of the individual himself is not the main concern. This is perhaps fortunate, as advances made on philanthropic grounds alone have never progressed very rapidly. In business and industry, new ideas are urgently needed for survival - this was especially evident after World War II which was, in the end, really a battle of ideas. The importance of this implication has not decreased with distance in time from that conflagration, indeed, individuals in the armed services are probably the people most deeply involved in and the most concerned with the problem of developing creative thought. "We are in a mortal struggle for the survival of our way of life", writes Guilford. "The need (for developing creativity) is a national crisis" says Anderson*. Intro., p. 1.

This dissertation identified and addressed four of the unresolved issues pertaining to the proposition that nonabsolute/ relativistic (N/R) thinking is one of the possible unifying commonalities underlying the selected models of postformal reasoning, namely Problem Finding, Dialectical Reasoning, Relativistic Operations and Reflective Judgment. A total of 254 participants aged 10 to 48 and attending Grade 5 to doctoral studies were involved. Each participant was administered eight tests in pencil-and-paper format to measure eight different constructs of thinking. Different specific hypotheses were evaluated through different statistical approaches. The four identified issues were addressed as follows: Firstly, nonabsolute/ relativistic thinking was reconceptualized and operationally defined as a multidimensional and multilevel construct. Two dimensions were proposed: the basic form and the epistemic view. Within the basic form dimension, two levels were proposed: the formal and the postformal forms. Secondly, a battery of three tests was specifically designed by Arlin and the author to measure the different dimensions and levels of nonabsolute/ relativistic thinking. Thirdly, strong empirical evidence was obtained supporting the general hypothesis that nonabsolute/ relativistic thinking is a possible unifying commonality underlying the four selected postformal models. Within the construct of nonabsolute/ relativistic thinking, two dimensions, the basic form and the epistemic view, can be differentiated as hypothesized. Fourthly, empirical evidence was also obtained supporting the general hypothesis that nonabsolute/ relativistic thinking is an instance of both formal and postformal reasoning. Specifically within the basic form dimension, two qualitatively different forms, the formal and the postformal, can be differentiated as hypothesized. Findings also suggested that the development of a nonabsolute epistemic view might play a crucial role in the development of the postformal form. Therefore, the emergence of the postformal form can be explained by a paradigm shift from an absolute to a nonabsolute epistemic view. Performances in the tests of the postformal form and of the epistemic view in combination were found to be good predictors of performances in the selected postformal tests. Significant implications of the findings are that nonabsolute/ relativistic thinking represents a form of metamorphosis from closed-system to open-system thinking and it might serve as a potential springboard in the development of higher order thinking. / Education, Faculty of / Educational and Counselling Psychology, and Special Education (ECPS), Department of / Graduate

This thesis traced the development of the concept of creativity from the earliest works in the intellectual history of Western civilization to the late twentieth century. This historical perspective on the concept of creativity served as a backdrop to current views of the concept and as a reference source for recurrent views of the concept and as a reference source for recurrent and essential themes in the progressing debates concerning this issue.

Winnicott’s (1968, 1993) play technique squiggling was piloted as a measure of creative thinking abilities and a potential diagnostic aid in the assessment of Asperger syndrome. The internal consistency and inter-rater reliability of squiggling was found to be acceptable. Mixed results were found between the six subscales in terms of concurrent validity with the Torrance Tests of Creative Thinking (TTCT: Torrance, Bal & Safter, 2008). Squiggling subscales Elaboration and Imagination showed signs of psychometric strength. However, Fluency and Originality require revision. Concurrent validity of the subscales Flexibility and Integration were not established. A matched-participants design enabled testing of hypothesised differences in creative thinking abilities with children with Asperger syndrome using the TTCT (Torrance et al., 2008): Abstractedness, Fluency, Originality, Integration, Elaboration, Resistance to Premature Foreclosure and Flexibility. Children with Asperger syndrome demonstrated a significantly higher level of elaboration and abstract imagination in their drawings relative to a comparison group of typically-developing children matched on age, visual motor integration ability and non-verbal IQ. Findings indicate partial support for the Weak Central Coherence Theory (Shah and Frith, 1983) and Leslie’s (1987) Meta-Representational Deficit hypothesis. Children with Asperger syndrome demonstrated understanding and expression of abstract concepts as graphical representations, thereby supporting their use in clinical assessments and interventions. No support was found for the Executive Dysfunction Theory (Pennington & Ozonoff, 1996) or for the Hyper-Systemising Theory (Baron-Cohen, 2006). Some limitations include the heterogeneity of the clinical group, and the possible confounding effects of verbal intellectual abilities, extrinsic rewards and performance anxiety. Major strengths of the study include a successful matching procedure and the finding of group differences with large effect sizes on particular creative thinking abilities.
