Intellectual abilities of symbolic and semantic judgment.

This is the authors' abstract. We don't add key points for this paper.

Two studies approached the problem of describing judgmental processes from the standpoint of individual differences in terms of basic traits. Based upon Guilford's structure-of-intellect model, the factors of symbolic and semantic evaluation were hypothesized to exist as distinct from one another and also from factors represented in other domains of the model. Experimental tests were developed as measures of the hypothesized factors. Measures of reference factors were also employed to demonstrate the uniqueness of the hypothesized factors. The tests were administered to 2 samples of high-school students, scores were factor analyzed, and axes analytically rotated, resulting in the demonstration of the 12 hypothesized evaluation factors and all the reference factors as uncorrelated dimensions of intellectual ability. The conclusion is that the model has continued to lead fruitfully to undiscovered, differentiable intellectual aptitudes. (Author)
