A central question in cognitive neuroscience concerns the extent to which language enables other higher cognitive functions. In the case of mathematics, the resources of the language faculty, both lexical and syntactic, have been claimed to be important for exact calculation, and some functional brain imaging studies have shown that calculation is(More)
This article explores how consideration of acquired speech and language disorders from the perspective of neuroscience permits new insights into the content and design of therapy for people with aphasia. Key proposals are that aspects of current therapies often neglect the sensory-motor components of speech and language processing, and the interconnectivity(More)
Debates about the role of language in human thinking are increasingly prominent in the cognitive sciences. There are claims that certain forms of reasoning can only be performed through access to the resources of the language faculty. In particular, a component of social cognition involving the representation of the mental states of others ('theory of mind'(More)
BACKGROUND The language profile of behavioral variant frontotemporal dementia (bvFTD) remains to be fully defined. OBJECTIVE We aimed to quantify the extent of language deficits in this patient group. METHODS We assessed a cohort of patients with bvFTD (n = 24) in relation to patients with semantic variant primary progressive aphasia (svPPA; n = 14),(More)
This cross-language study of working memory compared 30 English speakers and 30 Mandarin Chinese speakers on backward and forward digit and spatial span. Mandarin speakers had greater spans on forward digit and spatial span than did English speakers. Effects were most significant for digit span where the mean score of the English speakers was equivalent to(More)
Artificial grammar learning (AGL) is a widely used experimental paradigm that investigates how syntactic structures are processed. After a familiarization phase, participants have to distinguish strings consistent with a set of grammatical rules from strings that violate these rules. Many experiments report performance solely at a group level and as the(More)
We report an investigation of the production of real and non-words in two normal speaker groups. Group 1 consists of 6 young females (mean age 26 years) and Group 2 consists of 5 older females (mean age 54 years). The speech material used in the study consisted of two repetitions of 10 real, 10 pseudo-real and 10 non-words. The results from both repetitions(More)
In a recent article, explore whether apraxia of speech (AOS) can be explained by disruption of the phonetic plans for high frequency syllables. This approach is a hybrid one, combining the notion of a mental syllabary with an explanation that the impairment in AOS results from reduced access to supra-segmental phonetic plans. In this commentary, we explore(More)
