Abstract Word Deficits in Aphasia: Evidence From Semantic Priming

Word Deficits in Aphasia: Evidence From Semantic Priming L. K. Tyler, H. E. Moss, and F. Jennings Birkbeck College, University of London J.G. and D.E. are nonfluent aphasic patients who appear to have selective problems with abstract words on a variety of standard tests. Such a pattern would normally be interpreted as indicating a central semantic deficit for abstract words. The authors show th...

The organization of conceptual knowledge: the evidence from category-specific semantic deficits.

Questions about the organization of conceptual knowledge in the human brain can be addressed by studying patients with category-specific semantic deficits: disproportionate and even selective impairment of conceptual knowledge of one category of objects compared with other categories. Recently, consensus has emerged regarding the basic facts of category-specific semantic deficits: (1) the categ...

Modality specific word comprehension deficits in deep dyslexia.

A deep dyslexic patient was tested on a series of experiments designed to assess her comprehension of abstract words. On tests where a precise semantic representation of words was required, performance was much poorer with visual than with auditory presentation. However, on some but not all categorisation tests performance with both modalities was good. It is argued that deep dyslexia can resul...

Single-word predictions of upcoming language during comprehension: Evidence from the cumulative semantic interference task.

Comprehenders predict upcoming speech and text on the basis of linguistic input. How many predictions do comprehenders make for an upcoming word? If a listener strongly expects to hear the word "sock", is the word "shirt" partially expected as well, is it actively inhibited, or is it ignored? The present research addressed these questions by measuring the "downstream" effects of prediction on t...
