Purpose: The study's primary aims were to describe the long-term speech outcomes for adolescents and young adults with a history of childhood apraxia of speech (CAS) and to examine the association of persistent speech sound errors with measures of literacy skills, phonological processing, motor speech production, and parent report of early motor…

The ability to acquire language is a critical part of human development. Yet there is no consensus on how the skill emerges in early development. Does it constitute an innately-specified, language-processing module or is it acquired progressively? One of Annette Karmiloff-Smith's (1938-2016) key contributions to developmental science addresses…

Purpose: This article was written as an editorial to a collection of original articles on apraxia of speech (AOS) in which some of the more recent advancements in the understanding of this syndrome are discussed. It covers controversial issues concerning the theoretical foundations of AOS. Our approach was motivated by a change of perspective on…

Language is proposed to have developed atop the human analog of the macaque mirror neuron system for action perception and production [Arbib M.A. 2005. From monkey-like action recognition to human language: An evolutionary framework for neurolinguistics (with commentaries and author's response). "Behavioral and Brain Sciences, 28", 105-167; Arbib…

This study investigated the production of linguistic prosody in subjects with left hemisphere damage (LHD). Three experiments involving the production of lexical stress in nouns vs verbs, compound nouns vs tag constructions, and echo questions vs statements were conducted. Acoustic measurements (fundamental frequency (F[subscript 0]), duration and…

Understanding the precursors and early indicators of dyslexia is key to early identification and effective intervention. Now there's a single research volume that brings together the very latest knowledge on the earliest stages of dyslexia and the diverse genetic, neurobiological, and cognitive factors that may contribute to it. Based on findings…

Bilateral vascular thalamic lesions are rare. Although a variety of neurobehavioral manifestations have been described, the literature is less documented with regard to accompanying linguistic disturbances. This article presents an in-depth neurolinguistic analysis of the language symptoms of a patient who incurred bilateral paramedian ischemic…

It is generally well known that linguistic perseveration is a common symptom in individuals with brain damage and that its manifestation may be at the phonological, syntactic and/or semantic levels. The influence of perseveratory behavior on a subject's response to test stimuli and in therapeutic process has triggered the interests of the speech…

The aim of the present study is to compare the pragmatic ability of right- and left-hemisphere-damaged patients excluding the possible interference of linguistic deficits. To this aim, we study extralinguistic communication, that is communication performed only through gestures. The Cognitive Pragmatics Theory provides the theoretical framework:…

Presents a new set of experimental data from brain-damaged aphasic patients as well as from normal individuals on the processing of two nominals suffixes in Japanese--"-sa" and "-mi." (Author/VWL)

For 25 years now, there has been a serious attempt to get at the fundamental cause(s) of dyslexia in our laboratory. A great deal of research has been carried out on the psychological and brain underpinnings of the linguistic dysfunctions seen in dyslexia, but attempts to get at its cause have been limited. Initially, observations were made on the…

Purpose: Corticomuscular electroencephalographic-electromyographic (EEG-EMG) coherence elicited by speech and nonspeech oromotor tasks in healthy participants and those with Parkinson's disease (PD) was examined. Hypotheses were the following: (a) corticomuscular coherence is demonstrable between orbicularis oris (OO) muscles' EMG and scalp EEG…

This brochure discusses briefly, in lay terms, how one individual can approach communicating with another individual who has suffered a stroke. Two kinds of aphasia (language loss) are distinguished: Broca's aphasia, in which the ability to process grammar is impaired, and Wernicke's aphasia, in which neurological damage impairs the ability to…

This paper reports an investigation into the dynamics of language processing. The experiment reported here consisted of administering an anagram test to samples from three populations: left brain-damaged with aphasia; right brain-damaged without aphasia and a normal control group. Data are discussed regarding performance in language processing.…
