Impaired retrieval of semantic information: preserved em, visual perception, and speech production. Evidence for sm & em as interdependent systems: kan, alexander, & verfaelli (2009, background: compared three groups; amnesiac patients with mtl-only damage, amnesiac patients with mtl + Organization of concepts: categories: we categorize for two reasons, predict our environment, less time and effort thinking. In sd representations of objects degrade as the disease progresses (i. e. start going from specific general and specific. Using concepts: situated simulation theory: concepts are rarely processed in isolation, context + individuals goals influence the representation of concepts. Neural representations of concepts: three models, distributed only: evidence from situation simulation theory, hub only: evidence from sd, hub-and-spoke, method: name pictures (living, nonliving manipulable, nonliving non-manipulable), iv: site of tms and object type and. Increases rt for low and high manipulable objects. In ipl only for nonliving things: only increases rt for highly manipulable objects.
