The selective impairment of semantic memory is described in three patients with diffuse cerebrallesions. These patients, selected on the basis of a failure to recognize or identify common objects (agnosia for objects), were investigated in detail. In particular, their perceptual, language and memory functions were assessed, and the limits and properties of their recognition difficulties explored. It was found that knowledge of pictorial representations of objects, and of words, was impaired or… 

Neuropsychological studies of verbal semantic systems

The selective impairment of verbal comprehension in patients with cerebral lesions provides a powerful and direct source of evidence regarding the properties of verbal semantic systems. Word

Loss of semantic memory: implications for the modularity of mind

Abstract We report a patient, PP, with semantic dementia who was studied longitudinally over two years. During this period she showed a progressive and profound loss of semantic memory affecting

Interaction between vision and language in category-specific semantic impairment

Abstract A category-specific semantic disorder, selectively affecting Living things and food and sparing inanimate objects, was observed in a patient (LA) who had made a partial recovery from herpes

Category specific semantic impairments.

A quantitative investigation of the visual identification and auditory comprehension deficits of 4 patients who had made a partial recovery from herpes simplex encephalitis finds category specificity in the organization of meaning systems that are also modality specific semantic systems.

Structure and deterioration of semantic memory: a neuropsychological and computational investigation.

The authors present a parallel distributed processing implementation of this theory, in which semantic representations emerge from mechanisms that acquire the mappings between visual representations of objects and their verbal descriptions, to understand the structure of impaired performance in patients with selective and progressive impairments of conceptual knowledge.

Primary progressive semantic aphasia: A case study

Evidence for selective impairment of central semantic processing was obtained from experiments indicating item consistency of loss and the lack of semantic cuing, and the diagnosis of Pick's disease is suggested.

Semantic memory disorders

Semantic memory and language processing: a primer.

It is argued that treatment specificity demands a comprehensive understanding of the structure of semantic memory and the nature of its compromise, and several neuroanatomically informed theories of semantic organization with respect to the effects of semantic impairment on language processing in aphasia and neurodegenerative disease are reviewed.

Semantic memory in Alzheimer's disease

Semantic memory impairments have been hypothesised to underlie many of the language difficulties reported in probable Alzheimer's Disease, such as naming and verbal fluency. Contention exists

All three patients were severely and globally amnesic when tested with traditional recall and recognition procedures, and the possibility that medial temporal structures contribute to the ability to consciously reconstruct prior experiences was discussed.

Perceptual and associative disorders of visual recognition

IN 1890, Lissauerl described the first welldocumented case of visual agnosia and proposed a subdivision of this disorder into an apperceptive and an associative form, according to which stage of the

Independent Functioning of Verbal Memory Stores: A Neuropsychological Study

Five experiments are described concerning verbal short-term memory performance of a patient who has a very markedly reduced verbal span, indicating that he has a greatly reduced short- term memory capacity and showing that this cannot be attributed to a retrieval failure.

Word Recognition in a Phonemic Dyslexic Patient

It is argued that these findings support a dual encoding model of word recognition, the present case illustrating the impairment of the phonemic route, a direct graphemic-semantic route being relatively spared.

Acoustic confusions in immediate memory.

Sequences of 6 letters of the alphabet were visually presented for immediate recall to 387 subjects. Errors showed a systematic relationship to original stimuli. This is held to meet a requirement of

Patterns of paralexia: A psycholinguistic approach

A sample of the literature on acquired dyslexia is reviewed with special reference to the nature of paralexic errors. Linguistic studies of six cases of dyslexia are presented, with appropriate

Amnesic Syndrome: Consolidation or Retrieval?

The present experiments show that amnesic patients can remember verbal material if they are tested with a method of partial information but such retention depends more on the method of retrieval than on the methods of acquisition.
