A case of pure word deafness due to a left temporal infarct is reported. The results of dichotic tests suggest that auditory verbal material may be processed in the right hemisphere. The inability to repeat nonsense words, the frequent semantic paraphasias in real-word repetition tasks, and the capacity to give a partial account of the meaning of a word that the patient cannot repeat show that despite the impairment of the phonological analysis, lexical semantic processing is possible.

Word deafness and auditory cortical function. A case history and hypothesis.
Some arguments related to hemisphere specialization of phonetic processing and to the disconnection explanation of word deafness that support the hypothesis ofword deafness being generally caused by mixed deficits are discussed.
Disorder in Sequential Speech Perception: A Case Study on Pure Word Deafness
D disorders of a patient which were uniquely restricted to speech perception of syllable sequences after brain damage were described, in which the subject's repetition performance at the latter syllable position was remarkably poor.
Cerebral lateralization of language in deaf and hearing people
The possible effect of initial language acquisition on the development of hemispheric lateralization for language is discussed and both hearing and prelingually deaf signing adolescents showed a right hemisphere advantage for a face/nonface decision task.
On pure word deafness, temporal processing, and the left hemisphere
A woman with PWD resulting from a circumscribed unilateral infarct involving the left superior temporal lobe who demonstrated significant problems processing transitional spectrotemporal cues in both speech and nonspeech sounds is reported on.
Pure Word Deafness due to Left Hemisphere Damage
It is proposed that pure word deafness was consequent to the isolation of Wernicke's area from incoming auditory information due to the interruption both of the association fibers from the right auditory area traveling across the corpus callosum and of the left auditory radiations.
Dissociations in auditory word comprehension; evidence from nine fluent aphasic patients
Abstract Traditional aphasia classifications do not allow for a detailed description of auditory comprehension impairments. A cognitive neuropsychological model of lexical processing allows us to
Two routes to repetition: Evidence from a case of ‘deep dysphasia’
Her ability to repeat phrases was far better than could be expected from her single word repetition, suggesting that she uses for repetition tasks, a process that engages syntactic and semantic processes that is independent of a non-semantic route from auditory input to articulatory output.
A Case Study of Pure Word Deafness: Modularity in Auditory Processing?
AL, a woman with an acquired disturbance of auditory processing beginning in the second decade, was originally diagnosed as having pure word deafness. Recent analysis with a wide range of stimuli
Acquired word deafness, and the temporal grain of sound representation in the primary auditory cortex
It is argued that the disorder which underlies the speech discrimination deficit in the syndrome of acquired word deafness is not a generalized disorder of auditory temporal processing, but one which is largely restricted to the processing of sounds with temporal content in the milliseconds to tens ofmilliseconds time frame.
Short-term memory and verbal learning with auditory phonological coding defect: A neuropsychological case study
Results suggested that a standard, selective short-term memory defect can be induced by auditory phonological coding deficits as well as by "pure" short- term memory capacity limitation and other phonological deficits, and provided evidence that lexical-semantic code can allow normal verbal learning.


An analysis of speech perception in word deafness
Abstract A patient with a rather pure word deafness showed extreme suppression of right ear signals under dichotic conditions, suggesting that speech signals were being processed in the right
On the structure of word deafness and mechanisms underlying the fluctuation of disturbances of higher cortical functions
Abstract A case of pure word deafness was studied with special reference to the structure and dynamics of the comprehension deficit. It was found that the deficit was of an acoustic nature and that
Pure word deafness. Analysis of a case with bilateral lesions and a defect at the prephonemic level.
It is demonstrated that the deficit in speech perception in the patient with pure word deafness is secondary to a prephonemic temporal auditory acuity disorder and the presence of a predicted deficit in phonemic discrimination is demonstrated.
Selective semantic-lexical impairment of language comprehension in right-brain-damaged patients
Results have shown that right hemispheric lesions consistently impair semantic-lexical discrimination but do not hamper phoneme discrimination.
Auditory Vocabulary of the Right Hemisphere Following Brain Bisection or Hemidecortication
Results suggest a complex model of the development of language laterality in the brain, in which some, but not all, auditory language functions continue to develop in the right hemisphere past what is generally regarded as the critical period for language acquistion.
Hemispheric processing of intonation contours.

    Cortex; a journal devoted to the study of the nervous system and behavior

Results from the two experiments suggest that the right hemisphere is directly involved in the perception of intonation contours, and that normal language perception involves the active participation of both cerebral hemispheres.
The assessment of aphasia and related disorders
This small volume is designed as an introduction to the Boston Diagnostic Aphasia Test and deals briefly with the authors' concept of aphasia as a neuropsychological, psycholinguistic phenomena.
Interaction of information in word recognition.
The model has as its central feature a set of "logogens": devices which accept information relevant to a particular word response irrespective of the source of this information when more than a threshold amount of information has accumulated in any logogen.
