Hierarchical Network Model

(Lambon-Ralph et al., 2010)

Typicality driving object decision making: In semantic dementia, patients often make overgeneralisation and undergeneralisation errors by relying on surface features rather than conceptual meaning, such as judging a fox to be a dog, but not recognising a chihuahua as one

Williams, Nestor et al.

A Voxel-Based Morphometry (VBM) study by Williams, Nestor et al. found that gray matter loss in the anterior temporal lobes, particularly on both sides of the brain, strongly correlates with semantic memory deficits, supporting the Hub-and-Spoke Model and implying that the anterior temporal lobes serve as a central semantic hub responsible for integrating conceptual knowledge.

Warrington & McCarthy (1987)

Patient "YOT" showed a semantic deficit for non-living objects but preserved knowledge of vehicles, indicating that not all artifacts are affected equally in semantic impairment.

Dixon et al. (2000)

Reported that some patients with living thing impairments also had difficulty with musical instruments, suggesting that instruments may share representational features with living things.
