Beyond Baron and Kenny: Statistical Mediation Analysis in the New Millennium |
| |
| Abstract: | The relative effectiveness of visualization and verbalization as mediators of thought was investigated in two experiments. It was found that when subjects were required to pass on verbal instructions, they performed better in the presence of a visual referent. Subjects who were required to overtly visualize (draw) during a discrimination learning task performed as well on a subsequent transposition task as subjects who were required to overtly verbalize (talk). Both groups performed better than a control group which was not required to overtly visualize or verbalize. |
