Forty‐one high school students studied a series of five circuit diagrams. These either showed the electronic components as standard symbols or as squares. Each component was labelled and numbered. Students either had to remember the pattern of the elements in the diagram and draw it from memory, or they had to remember the elements in sequence. It was found that students who saw diagrams with symbols performed better on the sequence task and worse on the pattern task than the students who saw the diagrams with squares, whose performance on the two tasks was the opposite. A subsequent experiment found that requiring the students to label the elements in the diagrams did not interfere with their ability to remember the patterns of the components. It was concluded that students' success in completing tasks that require holistic or analytic processing depends upon the amount of detail in the elements in instructional diagrams. It was also suggested that designers of diagrams used to teach science can exercise some control over whether students process the information holistically or analytically by varying the amount of detail in the diagrams' elements.
