Editing Semantic memory (section)

===Modality-specific impairments===
Semantic memory is also discussed in reference to [[Stimulus modality|modality]]. Different components represent information from different sensorimotor channels. Modality specific impairments are divided into separate subsystems on the basis of input modality. Examples of different input modalities include visual, auditory, and tactile input. Modality-specific impairments are also divided into subsystems based on the type of information. Visual vs. verbal and perceptual vs. functional information are examples of information types.<ref>Valentine, T., Brennen, T. & Bredart, S. (1996).
