We present evidence that the comprehension of illustrated tee makes use of the visuospatial sketchpad component ofworking memory. The results from three experiments demonstrate that the comprehending of teats that are accompanied by pictures interferes with the performance of a spatial short-term memory task more than does the comprehending of texts that have no pictures. A fourth experiment demonstrates that the interference is found only when there is a requirement to comprehend the text; that is, the simple presentation of the texts and their pictures did not degrade performance on the spatial task. Finally, we show that the comprehension of illustrated texts does not differentially interfere with a verbal short-term memory task. These results are consistent with the claim that illustrations accompanying a text encourage the formation of a spatial mental model with the use of the working memory's sketchpad



Performance on the dot task did not differ significantly as a function ofthe presence or absence of a picture. In the absence of a requirement to comprehend, subjects performed equally well on the dot task, regardless of whether the picture was present. Data from the recognition task confirm that subjects looked at the screen during the experiment.
