Article
While research investigating the mediatisation of education policy has primarily been undertaken in school contexts, this paper reports on a study conducted in the context of early childhood education. The paper examines how a major policy in early childhood education in Australia – the National Quality Framework – has been mediatised in selected n...
Article
While an increasing body of Australian and international research has explored the relationship between media and education, few studies have examined this relationship in the context of early childhood education. This paper contributes to this research gap by reporting on a corpus-assisted discourse analysis of how childcare is represented in 801...
Article
Australia is home to Indigenous sign languages of varying degrees of complexity. In this paper we describe some of the features of the sign language(s) used in Arandic speaking communities of Central Australia. These sign languages have been referred to as ‘alternate’ because they are semiotic systems that are not usually the primary mode of commun...

This pilot study evaluates the ability of machined learned algorithms to assist with the differential diagnosis of dementia subtypes based on brief (< 10 min) spontaneous speech samples. We analyzed 1 recordings of a brief spontaneous speech sample from 48 participants from 5 different groups: 4 types of dementia plus healthy controls. Recordings w...
Article
Previous research has suggested that the left anterior insula, specifically the superior precentral gyrus of the insula (SPGI), is a critical brain region for the coordination of complex articulatory movements. However, previous studies have not determined which articulatory factors are specifically dependent on this brain region. In the current st...
Article
Background: A number of studies have suggested that temporal cortex is critical for the ability to generate exemplars belonging to a particular semantic category (i.e., category fluency), while frontal cortex is critical for generating words beginning with a particular letter (i.e., letter or phonemic fluency). However, previous studies have often...

Evidence is accumulating for the language use model in psycholinguistics, the social sciences as well as work in human computer interaction. Recent research in AAC has demonstrated the insufficiency of the sender-receiver model for characterizing augmented interactions. In this paper we will begin to provide a framework for showing how the AAC fiel...
Article

Research has shown that children with significant language impairments lag behind their typically developing peers in communicative and emotional competence. This article explores the importance of emotional competence in children with complex communication needs (CCN) and provides tools and strategies for individuals working with children with CCN...

Semantic dementia (SD) is a neurodegenerative disease characterized by atrophy of anterior temporal regions and progressive loss of semantic memory. SD patients often present with surface dyslexia, a relatively selective impairment in reading low-frequency words with exceptional or atypical spelling-to-sound correspondences. Exception words are typ...
Article
As universities adopt an increasingly international focus, student health professionals are keen to gain clinical experiences in other countries. Such clinical placements provide students with the opportunity to share their knowledge and at the same time acquire new clinical and cultural skills. The experience gained will not only enhance their cli...
Article
Full-text available
Six principles of AAC research and practice are offered for consideration and discussion within the AAC community. Principle 1 requires the active participation of individuals with complex communication needs (CCN) in all AAC activities. Principle 2 seeks to ensure that theoretical constructs underlying research and development in AAC are grounded,...

This study investigates whether sentence comprehension and nonsyntactic verbal working memory (vWM) are sustained by the same or by different neural systems. Scores in a sentence-picture matching task and in digits backward (DB) were correlated with magnetic resonance imaging voxelwise gray matter volumes using voxel-based morphometry in 58 patient...

Article
Narrative abilities have been identified as a link to successful school achievement and, in particular, to the acquisition of literacy. Children who use AAC may be at risk of impaired narrative facility due to the differences in their language learning experiences, limitation of their AAC systems, and limitations from constrained access to physical...
Article
Full-text available
Category and letter fluency tasks have been used to demonstrate psychological and neurological dissociations between semantic and phonological aspects of word retrieval. Some previous neuroimaging and lesion studies have suggested that category fluency (semantic-based word retrieval) is mediated primarily by temporal cortex, while letter fluency (l...
Article
In a previous study (Dronkers, 1996), stroke patients identified as having apraxia of speech (AOS), an articulatory disorder, were found to have damage to the left superior precentral gyrus of the insula (SPGI). The present study sought (1) to characterize the performance of patients with AOS on a classic motor speech evaluation, and (2) to examine...

Full-text available
Spatial language and cognition: Spatial cognition is a fundamental design requirement for every mobile species with a fixed territory or home base. And there is little doubt that it plays a central role in human thinking and reasoning. Indeed, the evidence for that centrality is all around us, in our language where spatial metaphors are used for ma...
Article
The chapters in this book present a kaleidoscopic impression of the range of variation in the linguistic treatment of the spatial domain. Each chapter presents a wealth of linguistic detail – what makes the overall exercise special is that, because each description uses the same elicitation devices, we can relatively easily set up fairly precise se...
Article
Spatial language - that is, the way languages structure the spatial domain - is an important area of research, offering insights into one of the most central areas of human cognition. In this collection, a team of leading scholars review the spatial domain across a wide variety of languages. Contrary to existing assumptions, they show that there is...
Article
In this chapter, I present a sketch of the linguistic properties of spatial description in Arrernte (otherwise known as Arunta, Aranda), an Aboriginal language spoken in Central Australia. In particular, I examine data collected from Eastern and Central (i.e. Mparntwe) Arrernte speakers living in Alice Springs. The language and its speakers Eastern...
Article
There has been a long-standing debate in the fields of philosophy and cognitive science surrounding the relationship of language to cognition, but the exact nature of this relationship is still unclear (Sokolov, 1968/1972). In the current study, we explored the role of language in one aspect of cognition, namely problem solving, by administering th...
Article
The cortical regions of the brain traditionally associated with the comprehension of language are Wernicke's area and Broca's area. However, recent evidence suggests that other brain regions might also be involved in this complex process. This paper describes the opportunity to evaluate a large number of brain-injured patients to determine which le...
Article
Executive deficits of problem solving and concept formation have been associated with frontal lobe dysfunction. Here we describe a new clinical test of concept formation based on the parlor game, Twenty Questions. The Twenty Questions Test requires examinees to ask the fewest number of yes/no questions possible in order to identify a target item fr...
Article
This presentation describes the design of an utterance-based communication device utilizing a Communication Frame approach to allow the selection of natural language utterances. Communication frames possess a schematic structure representing the situational structure off communication events which can be used to organize semantically and functional...
Article
Full-text available
This article tests earlier claims about the universality of patterns of polysemy and semantic extension in the domain of perception verbs. Utilizing data from a broad range (approx. 60) of Australian languages, we address two hypothesized universals. The first is Viberg's (1984) proposed unidirectional pattern of extension from higher to lower sens...

This project collected linguistic data for spatial relations across a typologically and genetically varied set of languages. In the linguistic analysis, we focus on the ways in which propositions may be functionally equivalent across the linguistic communities while nonetheless representing semantically quite distinctive frames of reference. Runnin...
Article
Absiract The purpose of this paper is to question some of the basic assumpiions concerning motion verbs. In particular, it examines the assumption that "come" and "go" are lexical universals which manifest a universal deictic Opposition. Against the background offive working hypotheses about the nature of'come" and ''go", this study presents a comp...
Article
The paper examines some of the semantic and pragmatic consequences of a form being both a lexeme (i.e. a simple sign) and a conventional utterance. The approach presented here has far-reaching consequences for the manner in which interjections are identified, analyzed, and subclassified. In particular it it suggested that interjections have all the...
Thesis
Full-text available
This thesis is essentially a description of the grammar of Mparntwe Arrernte, the traditional language of Alice Springs, in Central Australia. The main aims of the thesis are two-fold: (i) to provide a comprehensive descriptive overview of the language and (ii) to give some indication of how the language conveys, reflects and responds to the socio­...
Article
There were over 200 distinct languages in Australia at the time of European settlement. Today less than 40 of these are still being passed on to new generations, and all of these are under threat of extinction. Aboriginal people are struggling to adapt themselves to the massive European presence without losing their identity. The greatest threat to...
Article
This paper examines a set of five particle/clitics which are used for criticising and complaining in Mparntwe Arrernte (Aranda) — a Central Australian Aboriginal language. It describes how the illocutionary force of criticism and/or complaint achieved by each particle/clitic is a function of their meaning, culture specific pragmatics, and both the...
