Breskin Rigidity Test and Intelligence: An English Sample

Previous studies, such as by Schaie ( 1955), have suggested that rigidity is not a specific unique factor but a related set of dimensions. A subsidiary finding is thac a positive correlation is indicated between low rigidity and high intelligence. Breaking away from the traditional tests of rigidity, Breskin (1968) devised a short, non-verbal rigidiry test on the assumption that "a more rigid person, given the opportunity to express a preference between pairs of figures differing only in 'goodness of fit,' will tend to select the better fit." The test has 15 pairs of figures and the number of preferences for the 'good fit' figures account for the rigidity score. Since then Breskin and his associates have carried out further research and claim thac the test measures consistent and predictable individual differences in various cognitive areas including intelligence. Breskin, Gorman, and Hochman (1970) demonstrated that scores are unrelated to intelligence scores. Breskin and Rich ( 1971) used the Kuhlman-Anderson test to obtain intelligence scores for elementary school children and compared them with the rigidity scores. An over-all correlation of -0.106 confirmed their previous findings. In order to investigate the claims of the authors cited the test was administered together with the Shipley Abstract Reasoning Test (1940) to a group of 83 boys and 60 girls (aged 1 2 yr.) from an English Secondary Modern School. Breskin scores correlations with intelligence of -0.162 and -0.170 respectively. This relationship is non-significant and, although not as low as the findings of Breskin and Rich (197 l ) , supports their contention.
