Highlights
- •
A set of nested basic cognitive abilities underlying creative ideation in divergent thinking was proposed.
- •
A nested cognitive abilities structural model had excellent fit to the data.
- •
Mental speed, broad retrieval ability, and divergent thinking were all measured within the verbal domain.
- •
The proposed model is more effective for prediction of real-life criteria as compared to a classic three-dimensional CFA model.
- •
The used modeling approach allows to disentangle relevant cognitive components in the multipart concept of divergent thinking.
Abstract
Divergent thinking (DT) ability (i.e., the ability to come up with creative ideas) is a complex cognitive construct that has been associated with several specific components of the Cattel-Horn-Carroll (CHC) model. In this study, we employed a nested latent variable approach to examine the specific role of mental speed (Gs) and general retrieval ability (Gr) in DT ability, which was assessed by DT tasks that instructed to be creative and were scored for creative quality. Specifically, Gs was assumed to facilitate both Gr and DT, and Gr was assumed to contribute to DT. Successive latent variable models with orthogonal factors were tested to reflect these nested cognitive basic abilities. The proposed model of nested factors fit the data well: Latent Gs accounted for variation in Gs, Gr, and DT creative quality scores, latent Gr predicted performance in Gr and DT scores beyond Gs, and latent DT explained variation in DT scores beyond Gs and Gr. In addition, we related the resulting orthogonal latent variables to the external criteria of school grades to illustrate the explanatory power of the modeling approach. This study provides evidence that divergent thinking performance relies on mental speed and retrieval ability, as well as cognitive abilities unique to divergent thinking. We discuss consequences for the understanding of divergent thinking ability in the context of the CHC model.
