Such an assumption holds only if there is a single route from vision to action, mediated by access to semantic knowledge. At least two pieces of evidence contradict this assumption. Riddoch and Humphreys (1987) reported the case of a patient (J.B.) who was impaired both at naming and at matching functionally associated objects, from vision. In contrast, when given the names of the objects J.B. performed at ceiling level. Despite his apparent problems in visual access to semantic or functional knowledge, J.B. was generally good at making correct gestures to objects he failed to identify.
