  1. Note: RT formulation … response times for word problems of the condition formulation, RT story … response times for word problems of the condition story, C formulation … arcsin√p transformed rate of correct responses for word problems of the condition formulation, C story … arcsin√p transformed rate of correct responses for word problems of the condition story.
  2. The table shows the statistics for the regression coefficients of two separate linear regressions. The criterion variables were the values of the use of verbalization as well as visualization in solving arithmetic word problems (assessed with a short self-assessment). The predictor variables were verbal intelligence, numerical intelligence, figural intelligence, response times and arcsin√p transformed rates of correct responses for both conditions (formulation, story). The criterion variables were regressed on the predictor variables in two separate analyses. No significant correlation between the self-reported use of verbalization or visualization during solving arithmetic word problems and verbal, numerical or figural intelligence as well as performance was observed.
