Abstract
Goldstein (1948) reported multiple cases of failure to categorise colours in patients that lie termed amnesic or anomic aphasics. These patients have a particular difficulty in producing perceptual categories in the absence of other aphasic impairments. We hold that neuropsychological evidence supports the view that the task of colour categorisation is logically impossible without labels.
