However, there have been a few case reports of patients with spared reading despite profound semantic impairment. These reports have sparked an ongoing debate about how the brain processes conceptual versus(More)

Current views of semantic memory share the assumption that conceptual representations are based on multimodal experience, which activates distinct modality-specific brain regions. This proposition is widely accepted, yet little is known about how each modality contributes to conceptual knowledge and how the structure of this contribution varies across these(More)
How do the languages we speak shape the way we think? In a series of studies, Boroditsky, Schmidt, and Phillips (2003) investigated the effect of grammatical gender on people's responses to questions about the properties and similarity relations among objects. Here, we use a connectionist network to simulate these findings and find a possible mechanism for(More)
