Divergent thinking (DT) ability is widely regarded as a central cognitive capacity underlying creativity, but its assessment is challenged by the fact that DT tasks yield a variable number of responses. Various approaches for the scoring of DT tasks have been proposed, which differ in how responses are evaluated and aggregated within a task. The…

Scoring in creativity research has been a central problem since creativity became an important issue in psychology and education in the 1950s. The current study examined the psychometric properties of 27 creativity indices derived from summed and averaged scores using 15 scoring methods. Participants included 2802 middle-school students. Data…

Originality is scored based on standard zero-originality lists (ZOLs) in the Torrance Tests of Creative Thinking (TTCT). The applicability of those ZOLs to diverse groups has not been examined. We examined the consistency of TTCT-Figural's sample-based (SB) ZOLs and the published ZOLs based on a sample of predominantly African American college…

Background: The originality of divergent thinking (DT) production is one of the most critical indicators of creative potential. It is commonly scored using the statistical infrequency of responses relative to all responses provided in a given sample. Aims: Response frequency estimates vary in terms of measurement precision. This issue has been…

The present research examined the reliability of three types of divergent thinking tasks (unusual uses, instances, consequences/implications) and two types of subjective scoring (an average across all responses vs. the responses people chose as their top-two responses) within a latent variable framework, using the maximal-reliability "H"…

This study attempts to determine the extent of agreement on the Torrance Tests of Creative Thinking scores among independent scorers with no training other than individual study of the scoring guides, and a scorer trained by Torrance. (Author)

Verbal responses to several tests of originality were subjectively rated for originality. The ratings were compared with the statistical frequency of these responses in two samples of test takers, 150 elementary school children and 60 college students. The elementary school children were administered three measures from the Wallach and Kogar test…

The general usefulness of selected predictions equations for computer simulated scoring of creativity tests was studied. This was carried out by testing previously established prediction equations for samples drawn from similar populations. (CK)
