Reverse concreteness effects are not a typical feature of semantic dementia: evidence for the hub-and-spoke model of conceptual representation.
The role of anterior temporal lobes (ATLs) in semantic processing is controversial. One theory, influenced by semantic dementia (SD) patients, is that this region is a pan-modal hub for all concepts. An alternative view is that atrophy in SD specifically affects knowledge for visual features. This is supported by reports of reverse concreteness effects in a few SD patients, suggesting that abst...
متن کاملComprehension of concrete and abstract words in semantic dementia.
The vast majority of brain-injured patients with semantic impairment have better comprehension of concrete than abstract words. In contrast, several patients with semantic dementia (SD), who show circumscribed atrophy of the anterior temporal lobes bilaterally, have been reported to show reverse imageability effects, that is, relative preservation of abstract knowledge. Although these reports l...
متن کاملReversal of the concreteness effect in semantic dementia.
Patients with semantic dementia (SD) have a striking impairment in semantic memory, but the basis for this deficit is unclear. We examined semantic memory for concrete and abstract verbs with a two-alternative, forced-choice measure of lexical semantic associative knowledge. Patients with SD had significantly greater difficulty with concrete verbs (z = -3.33) than with abstract verbs (z = -2.05...
متن کاملBe concrete to be comprehended: consistent imageability effects in semantic dementia for nouns, verbs, synonyms and associates.
There are two contrasting views on the nature of comprehension impairment in semantic dementia: (a) that it stems from degradation of a pan-modal "hub" that represents core conceptual knowledge or (b) that it results from degradation of modality-specific visual feature knowledge. These theories make divergent predictions regarding comprehension of concrete versus abstract words in the disorder....
متن کاملAnomia: a doubly typical signature of semantic dementia.
This study was designed to explore the nature of the anomia that is a defining feature of semantic dementia. Using a pool of 225 sets of picture naming data from 78 patients, we assessed the effects on naming accuracy of several characteristics of the target objects or their names: familiarity, frequency, age of acquisition and semantic domain (living/non-living). We also analysed the distribut...
