Description: Planning and execution are two important parts of the problem solving process. Based on related research, we expect that planning and execution are positively correlated because of underlying individual differences in general mental speed, while we also expect a direct negative effect of actual planning time on execution time because we believe that an investment in planning contributes to more efficient execution. The positive correlation and the negative dependencies are not contradictory since the former is a relationship between latent variables and the latter is a relationship between manifest task-specific times, controlling for the latent variables. Employing GLMM and factor analysis, we have examined these two different kinds of relationships. The results supported the above hypotheses. Moreover, the negative dependencies were found to vary among persons and among items. In sum, this study provides a clearer picture of the relationship between planning and execution and suggests that analyses on different levels may show different relationships.
