Lexical-Semantic and Phonological Processing Deficits in Wernicke’s Aphasia

This study investigates the lexical-semantic and phonological processing deficits in Wernicke’s aphasia by comparing with healthy controls aiming to shed light on the causes of impairment.

Are Reading and Spelling Phonologically Mediated? Evidence from a Patient with a Speech Production Impairment

In this paper, we report the case of a patient, PS, who shows excellent comprehension of the meaning of words despite making a large number of phonemic paraphasias on tests of oral reading,

The production of stereotyped neologisms in aphasia: A case study

Abstract This case study describes the speech production of the aphasic patient, T. W., whose oral speech is characterized by frequent stereotyped neologisms. In his spontaneous speech, particularly

Neurolinguistic Aspects of Finnish Posterior Aphasia.

ABSTRACT Examination of the lexical errors (phonological paraphasias and neologisms) of two posterior aphasic patients who are speakers of Finnish, a highly synthetic language, revealed that the

Modelling Paraphasias in Normal and Aphasic Speech

We model word substitution errors made by normal and aphasic speakers with an interactive activation model of lexicalization. This comprises a three-layer architecture of semantic, lexical, and

Selective Impairment in First Language with Preserved Second Language Articulation: A Case Study

In this article, we report the case of patient KK who, following cerebral infection, appears to have lost communicative ability in her first language but can communicate effectively in a second

Selective impairment of semantics in lexical processing

Abstract We report the performance of a neurologically impaired patient, KE, whose frequent errors in reading, writing, naming, and comprehension were nearly always semantically related to the target

Phonological naming therapy in jargon aphasia: positive but paradoxical effects.

It seemed that the naming disorder was primarily due to an inability to access phonology from semantics, and performance on phonological judgment and discrimination assessments was unchanged, and there were no signs that the patient was self-cuing during naming.

Age of acquisition and lexical processing in aphasia: a case study

Abstract This paper presents a single-case study of an aphasic patient, NP, whose lexical processing was affected by age of acquisition, such that words typically acquired early in life were



Components of the Mental Lexicon

This paper sets out to identify, in information-processing terms, the elementary functional components of the mental lexicon and their interrelations. In particular it is concerned with the

Hesitation and the production of verbal paraphasias and neologisms in jargon aphasia

Wernicke's and global aphasia without alexia.

It is proposed that the right hemisphere in some individuals may be capable of extracting semantic information from iconic images (ideogram) without phonological processing.

A redefinition of the syndrome of Broca's aphasia: Implications for a neuropsychological model of language

A critical review of the literature provides the basis for a redefinition of the syndrome that considerably broadens its classical description, and the argument is advanced that the focus of neuropsychological explanation should be on theoretically separable psychological mechanisms that might be disrupted in relative isolation from other components in conditions of focal brain damage.

Semantic and syntactic processes in aphasia: a review of the literature.

It is argued that studies of aphasic language provide a valuable source of constraints on theories of normal language processing and support theoretical assumptions concerning the functional independence of various components ofnormal language processing.
