Relation between impairments for a type or modality of knowledge and category-specific semantic deficits. These data show that (a) category-specific semantic impairments are associated with impairments for all types of knowledge about the impaired category, (b) differential impairments for visual/perceptual knowledge can be associated with (if anything) a disproportionate impairment for nonliving things compared to living things, and (c) selective impairment for knowledge of object color is not associated with a corresponding disproportionate deficit for fruit/vegetables. Data for EW from Caramazza & Shelton 1998; GR and FM from Laiacona et al. 1993; DB from Lambon Ralph et al. 1998; and RC from Moss et al. 1998.
