This review discusses the relationship between neuroscience and psychoanalysis and introduces a new scientific method called neuro-psychoanalysis, a combination of the two phenomena. A significant difference between the two is that psychoanalysis has not evolved scientifically since it has not developed objective methods for testing ideas that it…

Purpose: The aims of the study were to assess and compare grammatical deficits in written and spoken language production in subjects with agrammatic primary progressive aphasia (agPPA) and in subjects with agrammatism in the context of dominant apraxia of speech (DAOS) and to investigate neuroanatomical correlates. Method: Eight agPPA and 21 DAOS…

One of a series of semiannual reports, this publication contains 14 articles which report the status and progress of studies on the nature of speech, instrumentation for its investigation, and practical applications. The titles of the articles and their authors are as follows: "Gestural Structure and Phonological Patterns" (Catherine P.…

The aim of this study is to test the validity and reliability of the Bilingual Aphasia Test as a measure of language impairment in a Greek-speaking Broca's aphasic population and to investigate relationships with the same aphasic group's performance on the Greek version of the short form of the Boston Diagnostic Aphasia Examination battery, mainly…

This article examines Verb Network Strengthening Treatment (VNeST), a relatively new treatment approach for anomia in people with aphasia. The VNeST protocol aims to promote generalization to increased lexical retrieval of untrained words across a hierarchy of linguistic tasks, including single-word naming of nouns and verbs, sentence production,…

We used eye-tracking to investigate lexical processing in aphasic participants by examining the fixation time course for rhyme (e.g., "carrot-parrot") and cohort (e.g., "beaker-beetle") competitors. Broca's aphasic participants exhibited larger rhyme competition effects than age-matched controls. A re-analysis of previously reported data (Yee,…

We explored the neural basis of reversible sentence comprehension in a large group of aphasic patients (n = 79). Voxel-based lesion symptom mapping revealed a significant association between damage in temporo-parietal cortex and impaired sentence comprehension. This association remained after we controlled for phonological working memory. We…

In aphasia literature, it has been considered that a speech repetition defect represents the main constituent of conduction aphasia. Conduction aphasia has frequently been interpreted as a language impairment due to lesions of the arcuate fasciculus (AF) that disconnect receptive language areas from expressive ones. Modern neuroradiological…

Artificial grammar learning constitutes a well-established model for the acquisition of grammatical knowledge in a natural setting. Previous neuroimaging studies demonstrated that Broca's area (left BA 44/45) is similarly activated by natural syntactic processing and artificial grammar learning. The current study was conducted to investigate the…

Low frequency Repetitive Transcranial Magnetic Stimulation (rTMS) has previously been applied to language homologues in non-fluent populations of persons with aphasia yielding significant improvements in behavioral language function up to 43 months post stimulation. The present study aimed to investigate the electrophysiological correlates…

Many studies have shown that verb inflections are difficult to produce for agrammatic aphasic speakers: they are frequently omitted and substituted. The present article gives an overview of our search to understanding why this is the case. The hypothesis is that grammatical morphology referring to the past is selectively impaired in agrammatic…

This article reconsiders the events that took place at the 1868 meeting of the British Association for the Advancement of Science (BA) in Norwich. Paul Broca and John Hughlings Jackson were invited to speak on the new and controversial subject of aphasia. Over the ensuing decades, there have been repeated references made to a debate between Broca…

In this paper, we investigate the ability of Dutch agrammatic Broca's and Wernicke's aphasics to assign reference to possessive pronouns in elided VP constructions. The assumption is that the comprehension problems in these two populations have different sources that are revealed in distinct patterns of responses. The focus is primarily on the…

A hypothesis for the aphasic syndrome of aggramatism--the omission of function words and inflectional morphemes--is presented. The author tests and illustrates the efficacy of closely observing substantive universals of grammatical structure in proposing accounts of linguistic defects. (Author/MV)

In the past verb retrieval problems were associated primarily with agrammatism and noun retrieval difficulties with fluent aphasia. With regards to fluent aphasia, so far in the literature, three distinct patterns of verb/noun dissociations have been described for individuals with fluent anomic aphasia in languages with different underlying forms;…
