Three shape recognition tasks are examined: matching two shapes, matching a written name to a shape, and naming shapes orally. In each the relevant dimension is shape, but the irrelevant dimensions of colour, orientation and proportion are varied. The effect of changes in the irrelevant dimensions in each task is used to infer the degree of specificity present in the internalized standard against which the test stimulus is matched. The fact that name–visual matches resemble visual–visual matches rather than naming latencies indicates that comparison in this task is based on a generated visual code.
