Abstract:
This chapter concerns one of the most central of human cognitive abilities, semantic memory, viewed from the perspective of the neuropsychological condition in which this centre falls apart. The chaper begins with summaries of the cognitive, neuroanatomical and pathological features of semantic dementia, and then reviews recent research addressed to two questions: (i) Is semantic memory one or several systems? Differences associated with the contributions of left- and right-temporal lobes to conceptual knowledge; (ii) Is semantic memory one or several systems? Differences associated with words vs objects as input, and with speech vs action as output.
