Psychopathy is often characterized in terms of what I call “the language of disorder.” I question whether such language is necessary for an accurate and precise characterization of psychopathy, and I consider the practical implications of how we characterize psychopathy—whether as a biological, or merely normative, disorder.

The Language of Symmetry is a re-assessment of the structure and reach of symmetry, by an interdisciplinary group of specialists from the arts, humanities, and sciences at Oxford University. It explores, amongst other topics order and chaos in the formation of planetary systems entropy and symmetry in particle physics group theory, fractals and self-similarity symmetrical structures in western classical music, and how biological systems harness disorder to create order. This book aims to open up the scope of interdisciplinary (...) work in the study of symmetry and is intended for scholars of any background - whether it be science, arts or philosophy. (shrink)

Despite strong evidence that worry is a verbal process, studies examining linguistic features in individuals with generalised anxiety disorder (GAD) are lacking. The aim of the present study is to investigate language use in individuals with GAD and controls based on GAD and worry theoretical models. More specifically, the degree to which linguistic elements of the avoidance and intolerance of uncertainty worry models can predict diagnostic status was analysed. Participants were 19 women diagnosed with GAD and 22 control (...) women and their children. After participating in a diagnostic semi-structured interview, dyads engaged in a free-play interaction where mothers' language sample was collected. Overall, the findings provided evidence for distinctive linguistic features of individuals with GAD. That is, after controlling for the effect of demographic variables, present tense, future tense, prepositions and number of questions correctly classified those with GAD and controls such that a considerable amount of the variance in diagnostic status was explained uniquely by language use. Linguistic confirmation of worry models is discussed. (shrink)

Lateral temporal measures of the auditory evoked potential including the T-complex, as well as an earlier negative peak index maturation of auditory/speech processing. Previous studies have shown that these measures distinguish neural processing in children with typical language development from those with disorders and monolingual from bilingual children. In this study, bilingual children with Turkish as L1 and German as L2 were compared with monolingual German-speaking children with developmental language disorder and monolingual German-speaking children with TD in (...) order to disentangle effects of limited language input vs. reduced perceptual abilities in the processing of speech and non-speech stimuli. Sensory processing reflected by the T-complex was compared in response to a German vowel and a sine-wave tone in the three groups of children, ages 5 through 6 years. Stimuli were presented while children watched a muted video. Auditory evoked potentials were time-locked to the vowels and tones. AEPs to the frequent stimuli within an oddball paradigm were analyzed at the left and right temporal electrode sites.The results revealed language status, stimulus, and language test measures all influenced the T-complex amplitudes. Particularly, the peak amplitude of Ta was modulated by language status and stimulus type. Bilingual children had significantly more negative Ta responses than the monolingual children with TD for both vowels and tones while DLD children differed from TD children only for the vowel stimulus. The amplitude of the T-complex was overall more negative at the left than at the right site. The Na peak latency was longer for the bilingual group than that observed for the two monolingual groups. The Tb latency was shorter for DLD and bilingual groups than that for TD children in the vowel condition, but no such latency difference between DLD and bilingual children was found. We suggest that the attenuated T-complex for bilingual children indicates continued plasticity of the auditory cortex to allow for learning of novel, second-language speech sounds. (shrink)

Children with developmental language disorder reportedly struggle with the comprehension of aspect. However, since aspect and tense are closely entangled in the languages spoken by the children with DLD in previous studies, it is unclear whether the difficulty stems from aspect, tense, or both. Mandarin Chinese, a language without morphological manifestations of tense, is ideal to investigate whether the comprehension of aspect is specifically affected in children with DLD, yet to date work on this is scarce and (...) presents methodological limitations. In this study, we examined whether preschool Mandarin-speaking children with DLD have difficulty in comprehending perfective aspect compared to imperfective aspect, whether performance can be explained in terms of the pre- vs. post-verbal realization of the aspect markers, and the potential role played by lexical aspect in the comprehension of grammatical aspect. Fourteen preschool children with DLD and 14 TD children matched for age and nonverbal intelligence participated in a sentence-picture matching task. Global results showed that, similar to their TD peers, children with DLD performed better on imperfective aspect than perfective aspect. Concerning specific aspect markers, while children with DLD indeed performed similarly to TD children on imperfective -zhe, they obtained significantly lower accuracy than TD children on perfective -le and imperfective zai-. However, considering verb types combined with these aspect markers, results revealed that children with DLD scored significantly higher on the prototypical combination than on the non-prototypical combination. The performance pattern suggests that the comprehension of aspect markers by children with DLD is particularly affected by lexical aspect. As this also affects younger TD children, children with DLD are arguably at an earlier stage of aspectual development than their age and nonverbal intelligence matched TD peers. Therefore, the aspectual development of children with DLD appears to be delayed rather than deviant. Given this, language programs addressing difficulties in DLD may need to incorporate training on the use of aspect markers, especially targeting their combination with non-prototypical verbs.

In lieu of an abstract, here is a brief excerpt of the content:Melancholy and the Therapeutic Language of Moral Philosophy in Seventeenth-Century ThoughtJeremy SchmidtThe concept of melancholy comprehended a wide range of characteristics and conditions in seventeenth-century European culture, from the brooding introspection of the genius and the scholar to a condition of delirious and delusory madness.1 Its central and most immediately identifiable characteristic, however, was the excessive and unreasonable nature of its symptomologically defining emotions of fear and sorrow. (...) As Robert Burton noted out in The Anatomy of Melancholy (1621), the melancholic condition was commonly taken to be "a kind of dotage without fever, having for his ordinary companions fear and sadness, without any apparent occasion."2 The presence of a pervasive and unreasonable sense of fear and sorrow invariably solicited the melancholic label. Indeed, melancholic emotions were the primary substance of melancholic dotage; the ravings of the melancholically mad and their frequent obsession with a single idea were often driven by an overwhelming feeling of fear and sorrow.3The concept of melancholy as a mental disorder involving these specific emotions had coalesced under the gaze of medical observation in ancient Greece, and the melancholic condition was thought by many medical theorists of classical [End Page 583] antiquity to be caused by a physiological surfeit of black bile, the Greek word for which was melancholia.4 Western medicine, profoundly influenced by the Greek medical tradition, continued to diagnose and treat melancholic disturbance as a physical distemper well into the nineteenth century. Yet the kind of mental anguish which early medical observers labeled melancholic bore a striking resemblance to forms of emotional disorder whose point of origin was thought to be the mind itself. Various traditions of classical moral philosophy sought to treat disorders of the mind that unchecked emotion could create primarily by directing, ordering, and correcting the thought of the sufferer. Where the melancholic condition displayed qualities of the emotions as these were represented and analyzed by moral philosophers it was viewed as susceptible to philosophical treatment and insight.5Early modern English writers, no less than classical writers, thought it appropriate to apply to cases of melancholy therapies derived from the philosophic endeavor to define and achieve peace of mind. Burton argued explicitly in The Anatomy of Melancholy for the rightful authority of the philosophical "physician of the soul" in the treatment of melancholy; and the conceptual similarity of melancholy to moral diseases of the soul which provided the basis for this authority is evidenced in the works of several seventeenth-century moralists, as well as in the writings of the influential seventeenth-century physician and natural philosopher Thomas Willis on melancholy and the passions. Willis noted that melancholic emotions were structured and caused by the judgments of the mind rather than by the force of physiological dysfunction alone. His recognition of the importance of the mental aspects of melancholy provided the basis for his prescription of moral therapies for the government of the mind in addition to therapies for the body. Moreover, his writing on the passion of grief displays the ability of moral philosophical language to represent melancholic-like states as problems of the moral life, to be engaged through rational meditation and control.The importance of moral philosophy in understanding and treating melancholy has been largely ignored in current scholarship in the history of psychiatry and madness, which has concentrated on early modern medical concepts of mental disorder that traced its origins to the body. The historian of psychiatry and "madness" Roy Porter has, for instance, referred to Willis's medical writings as evidence for the "thoroughgoing somatic grounding of disorders of thought, feeling and behavior" that he alleged to have dominated the era's medical [End Page 584] conceptualization and treatment of madness.6 While Michel Foucault insightfully noted that Willis's ostensibly chemical account of the nature of melancholy was in fact "a phenomenology of the melancholic experience," he dismissed out of hand the relevance of classical moral philosophical language to the early modern treatment of madness, asserting the complete absence of moral treatments of madness until the end of the eighteenth century.7 In analyzing Willis's writing he thus failed to note the broader moral philosophical...

Despite numerous studies on the treatment of developmental language disorder, the intervention effect has long been debated. Systematic reviews of the effect of language therapy alone are rare. This evidence-based study investigated the effect of language therapy alone for different expressive and receptive language levels in children with DLD. Publications in databases including PubMed, the Cochrane Library, the Wanfang Database and the China National Knowledge Infrastructure were searched. Randomized controlled trials were selected. The methodological quality (...) of the included trials was assessed using the modified Jadad method. RevMan 5.3 software was used for the data analysis. Fifteen trials were included in this study. Compared with the control group, the intervention group showed significant differences in overall expressive language development [standard mean differences, 0.46; 95% confidence interval, 0.12–0.80], mean length of utterances in a language sample, number of utterances in a language sample, parent reports of expressive phrase complexity, overall expressive vocabulary development and different words used in a language sample. However, language therapy did not show satisfactory long-term effects on DLD. Although language therapy is helpful in improving the performance of children with DLD, its long-term effect is unsatisfactory. (shrink)

Research on adolescent wellbeing in Developmental Language Disorder has previously been examined through measures of parent or self-reported wellbeing, but never has a study included both and enabled comparison between the two. The current study reports parent and self rated wellbeing of adolescents with DLD and Low Language ability, as well as their typically developing peers. It also examines consistency between raters and factors influencing correspondence. Adolescents aged 10–11 with DLD, LL or TD were recruited from eight (...) UK primary schools. A battery of standardized language, psychosocial and wellbeing assessments, including the KIDSCREEN-27 were administered. Adolescent ratings of wellbeing were similar across groups on three of the five wellbeing dimensions, but those with DLD had lower self-reported Autonomy and Parental Relations than their TD peers, and both the DLD and LL group had lower School Environment scores than their TD peers. By parental report, the DLD and LL group were considered to have lower wellbeing on all five wellbeing dimensions relative to their TD peers. Paired sample t-test analyses indicated a high level of variance between parent and adolescent reported wellbeing for multiple wellbeing domains, especially Psychological Wellbeing. Importantly, predictors of the level of agreement between parent and adolescent reported psychological wellbeing differed between groups: cognitive reappraisal and sociability predicted this level of agreement for adolescents with LL, while social competence predicted agreement in DLD and TD. This study emphasizes the necessity of allowing adolescents of all language abilities to report their own wellbeing, as their perspective does not align with that of their parents. It also highlights the importance of including the full spectrum of need when investigating the impact of language ability on consistency between proxy and self-reported wellbeing. (shrink)

Children with developmental language disorder (DLD) have significant deficits in language ability that cannot be attributed to neurological damage, hearing impairment, or intellectual disability. The symptoms displayed by children with DLD differ across languages. In English, DLD is often marked by severe difficulties acquiring verb inflection. Such difficulties are less apparent in languages with rich verb morphology like Spanish and Italian. Here we show how these differential profiles can be understood in terms of an interaction between properties (...) of the input language, and the child's ability to learn predictive relations between linguistic elements that are separated within a sentence. We apply a simple associative learning model to sequential English and Spanish stimuli and show how the model's ability to associate cues occurring earlier in time with later outcomes affects the acquisition of verb inflection in English more than in Spanish. We relate this to the high frequency of the English bare form (which acts as a default) and the English process of question formation, which means that (unlike in Spanish) bare forms frequently occur in third‐person singular contexts. Finally, we hypothesize that the pro‐drop nature of Spanish makes it easier to associate person and number cues with the verb inflection than in English. Since the factors that conspire to make English verb inflection particularly challenging for learners with weak sequential learning abilities are much reduced or absent in Spanish, this provides an explanation for why learning Spanish verb inflection is relatively unaffected in children with DLD.

This study is an investigation of both comprehension and production of Wh- questions in Malay-speaking children with a developmental language disorder. A total of 15 Malay children with DLD were tested on a set of Wh- questions, comparing their performance with two control groups [15 age-matched typically developing children and 15 younger TD language-matched children]. Malay children with DLD showed a clear asymmetry in comprehension of Wh- questions, with a selective impairment for which NP questions compared with (...) who questions. Age-matched controls performed at ceiling in all Wh- questions, while the language-matched group reported a subject/object asymmetry selective for the which NP, as reported in other languages. In production, both children with DLD and younger children showed a preference for questions with in situ Wh- elements, a structure that is allowed in colloquial Malay, but which is not produced by the age-matched TD group. Several non-adult-like strategies were adopted particularly by the children with DLD to avoid complex sentences, including substitution with yes/no echo questions, production of the wrong Wh- question, and use of a generic Wh- element. The study provides an insight on the mastery of Wh- questions in both typical Malay children and children with DLD. Implications for the definition of a clinical marker for DLD in a free word order language with Wh- in situ option will be discussed. (shrink)

In this thesis I develop an account of how processes of social understanding are implicated in experiences of mental disorder, critiquing the lack of examination of this phenomena along the way. First, I demonstrate how disorder concepts, as developed and deployed by psychiatric institutions, have the effect of shaping the cognition of individuals with psychopathology through setting expectations. Such expectation-setting can be harmful in some cases, I argue, and can perpetuate epistemic injustices. Having developed this view, I criticise (...) enactive accounts of mental disorder for failing to consider how such terms like ‘dysfunction’ are open to interpretation and can come embedded with normative expectations. Enactive accounts consequently run the risk of perpetuating injustices in their account of the sociality of mental disorder. Similar concerns arise when we consider the attachment of enactivism to the medical model, I argue. But by adapting enactivism to consider other experiences of disorder, such as those described as ‘madness’, enactive psychiatry may genuinely provide ethical groundwork for a better conception of disordered experience. Then, I consider a further concern with a distinctly medicalised conception of mental disorder from the perspective of self-illness ambiguity, arguing that self-illness ambiguities appear to form a special class of ambiguities due to their proximity to disorder concepts which mark them as appropriate targets for therapeutic treatment. However, I argue further that we should be critical of the idea that self-illness ambiguities necessitate disambiguation, as, in cases where self and illness are demarcated, individuals may still experience distress because simply having a mental disorder can be socially alienating. The medicalised focus in self-illness ambiguity, and the explicit need from the medical perspective to disambiguate it, might then exacerbate the distress someone experiences in mental disorder. Moreover, drawing on Mad Studies, I suggest that one might not need a coherent self-narrative to live well. Because of this, one may not need to adopt a medicalised view of the self in the case of selfillness ambiguity. In order to support this analysis, I provide a phenomenological account of language and argue that the very thoughts implicated in mental disorder shape the individual’s perception of the world due to the way that language foregrounds particular aspects of our world. This demands a critical examination of the language adopted and used by both clinicians and disordered individuals. I thus conclude with some thoughts on how to approach research and developing understanding of mental disorder given that we, as people, are always implicated in this process and therefore socialisation of some kind will always be taking place.

Children with developmental language disorder (DLD) served as a test case for determining the role of extant vocabulary knowledge, endogenous attention, and phonological working memory abilities in cross-situational word learning. First-graders (Mage = 7 years; 3 months), 44 with typical development (TD) and 28 with DLD, completed a cross-situational word-learning task comprised six cycles, followed by retention tests and independent assessments of attention, memory, and vocabulary. Children with DLD scored lower than those with TD on all measures of (...) learning and retention, a performance gap that emerged in the first cycle of the cross-situational protocol and that we attribute to weaknesses in initial encoding. Over cycles, children with DLD learned words at a similar rate as their TD peers but they were less flexible in their strategy use, demonstrating a propose-but-verify approach but never a statistical aggregation approach. Also, they drew upon different mechanisms to support their learning. Attention played a greater role for the children with DLD, whereas extant vocabulary size played a greater role for the children with TD. Children navigate the problem space of cross-situational learning via varied routes. This conclusion is offered as motivation for theorists to capture all learners, not just the most typical ones.

It has been suggested that language disorders can serve as real windows onto language evolution. We examine this claim in this paper. We see ourselves forced to qualify three central assumptions of the the ‘disorders-as-windows’ hypothesis. After discussing the main outcome of decades of research on the linguistic ontogeny of pathological populations, we argue that language disorders should be construed as conditions for which canalization has failed to cope fully with developmental perturbations. We conclude that a robust (...) link exists between developmental disturbances and evolutionary history that allows language disorders to be used as real windows onto the evolution of the neuronal substrate of language, and emphasize that our conclusion is more compatible with views of language evolution as the result of reorganizational changes as opposed to radically novel emergences.

The paper offers a conceptual and phenomenological analysis of the language of depersonalization. The depersonalization syndrome or disorder has no known common pathogenesis and shows no characteristic behavioral manifestations. A conceptual analysis of the key terms in the subjective complaints would therefore have consequences for clinical research into the phenomenon of depersonalization.

There is controversy as to whether children with developmental language disorder (DLD) and those with high-functioning autism plus language impairment (HFA-LI) share similar language profiles. This study investigated the similarities and differences in the production of Chinese negative sentences by children with DLD and children with HFA-LI to provide evidence relevant to this controversy. The results reflect a general resemblance between the two groups in their lower-than-TDA (typically developing age-matched) performance. Both groups encountered difficulties in using (...) negative markers, which suggests that they might be impaired in feature agreement. Slight differences were detected between the two groups. Specifically, children with DLD experienced difficulties with the agreement on the feature [+telic] and that on the feature [+dynamic], while children with HFA-LI had difficulties with the agreement on the feature [+dynamic] and that on the feature [−dynamic]. This study supports the idea of a common symptomatology for the two disorders. More importantly, it suggests that these two disorders, DLD and HFA-LI, are not altogether the same in terms of language impairment. This paper concludes that general labels should not be simply attached to any children with language disorders. Instead, atypical language is very worthy of further analysis in the categorization of language disorders. (shrink)

Communication problems are often the first noticeable symptom of developmental abnormalities. About 15% of children at the age of 2 years demonstrate a lower level of speech expression than their peers. Speech development disorders may constitute either symptoms of global developmental delay or only isolated difficulties. One of the main challenges for professionals dealing with early development support is recognizing whether a child whose linguistic competence differs significantly from that of their peers suffers from a specific language impairment, or (...) whether they belong to the group of ‘late bloomers’ who at some point, without the intervention of a specialist, will achieve an appropriate level of communication skills. Although a differential diagnosis can be extremely difficult, the analysis of the literature leads to the conclusion that there are some markers that can aid a specialist in establishing an accurate diagnosis.

Our visual environment is highly predictable in terms of where and in which locations objects can be found. Based on visual experience, children extract rules about visual scene configurations, allowing them to generate scene knowledge. Similarly, children extract the linguistic rules from relatively predictable linguistic contexts. It has been proposed that the capacity of extracting rules from both domains might share some underlying cognitive mechanisms. In the present study, we investigated the link between language and scene knowledge development. To (...) do so, we assessed whether preschool children with Developmental Language Disorder, who present several difficulties in the linguistic domain, are equally attracted to object-scene inconsistencies in a visual free-viewing task in comparison with age-matched children with Typical Language Development. All children explored visual scenes containing semantic, syntactic, or both inconsistencies. Since scene knowledge interacts with image properties to guide gaze allocation during visual exploration from the early stages of development, we also included the objects’ saliency rank in the analysis. The results showed that children with DLD were less attracted to semantic and syntactic inconsistencies than children with TLD. In addition, saliency modulated syntactic effect only in the group of children with TLD. Our findings indicate that children with DLD do not activate scene knowledge to guide visual attention as efficiently as children with TLD, especially at the syntactic level, suggesting a link between scene knowledge and language development.

Purpose: The purpose of this study is to better understand the characteristics of the language-related skills of bilingual children with specific learning disorders. The aim is achieved by analyzing language-related skills in a sample of bilingual and Italian monolingual children, with and without SLD.Patients and methods: A total of 72 minors aged between 9 and 11 were recruited and divided into four groups: 18 Italian monolingual children with SLD, 18 bilingual children with SLD, 18 Italian monolingual children without (...) SLD, and 18 bilingual children without SLD. Each child underwent tests to evaluate different aspects of language skills: lexical and grammar, metalanguage and executive functions.Results: With regard to lexical and grammatical skills, the conditions of SLD and bilingualism both impact naming in terms of total number of errors for words with low frequency of use, while the condition of SLD has an effect on semantic errors for words with low frequency of use. The condition of bilingualism impacts on the total errors for words with high frequency of use and on circumlocution-type errors for words with low frequency of use. There were significant effects of bilingualism and SLD on the metalinguistic test for understanding implicit meaning, and an impact of SLD on phonological awareness was also found.Conclusion: The results suggest that both SLD and bilingualism have an effect on some lexical skills, in particular for words with low frequency of use. Both conditions, bilingualism and SLD, seem to impact on metalinguistic abilities that depend on lexical knowledge. These findings reinforce the importance of improving understanding of the neuropsychological profile of bilingual children with SLD. (shrink)

Parent and preschool teacher ratings of the 10 noun categories of MacArthur-Bates Communication Development Inventory were used to study expressive language in 2–4-year-old children with autism spectrum disorder across the home and preschool context. There was no significant difference in the total number of words the children said in the two contexts, but the children said significantly more words in the noun categories “Furniture and rooms” and “People” at home. Only one third of the words the children said (...) were said both at home and in the preschool, while the other two thirds were said only at home or only in preschool. This suggests that what words the children use across contexts differ substantially and that their vocabulary is larger than it seems when measured only in one context. This novel study highlights the importance of assessing the language in children with ASD in multiple contexts in order to better measure their vocabulary and to design appropriate language interventions.

In the prior studies, the significance of working memory is linked to language acquisition which helped in understanding these disorders better (Wen, & Li, 2019). However, there is one component that is not being taken into consideration with Second Language Acquisition (SLA) (Choi, 2019). This study collected data from 122 adolescents and young adults (Female = 61, Male = 61) in the age range 15–22 years. Using four subtests of David’s Battery of Differential Abilities (DBDA), measures of VSSP (...) and verbal ability were measured. Multiple regression analysis was carried out between the measures of VSSP and verbal ability. The results showed promise and the measures of VSSP were found to be a positive predictor of second language comprehension in the current sample. Whereas, no gender differences were observed with regard to verbal ability. With the supporting literature, this study evidently provided insights into the overall relationship. (shrink)

In this article, I attempt to bring some colour to a discussion of fraught topics in education. Though the scenes and stories (from education and elsewhere) that feature here deal with racism, the discussion aims to say something to such topics more generally. The philosophers whose work I draw on here are Stanley Cavell and Judith Butler. Both Butler and Cavell develop (or depart from) J.L. Austin's theory of the performative utterance. Butler, following Derrida, argues that in concentrating on the (...) illocutionary force of utterances (their capacity to do things), Austin fails to account for the force of words themselves. The iterability of language means that words are never at one with themselves. They carry their old contexts with them as they enter into new ones. This has important consequences for ethical issues that pertain to what Butler calls the ?performativity? of gender and race. Though we are performed by language, this performance has a dynamic quality that leads to the reshaping of identity. In contrast, for Cavell, the disappointing aspect of Austin's thought relates to the latter's neglect of the perlocutionary effect of language ? what is done ?by words?. By taking on this project, Cavell embraces the unconventional aspects of language characterised by ?passionate? expression and exchange. Butler and Cavell approach the performative utterance from different directions. In the last part of this article, the significance of this difference is discussed in relation to the provision of a moral education with regard to tackling issues surrounding racism. (shrink)

Grammatical markers are not uniformly impaired across speakers of different languages, even when speakers share a diagnosis and the marker in question is grammaticalized in a similar way in these languages. The aim of this work is to demarcate, from a cross-linguistic perspective, the linguistic phenotype of three genetically heterogeneous developmental disorders: specific language impairment, Down syndrome, and autism spectrum disorder. After a systematic review of linguistic profiles targeting mainly English-, Greek-, Catalan-, and Spanish-speaking populations with developmental disorders (...) (n = 880), shared loci of impairment are identified and certain domains of grammar are shown to be more vulnerable than others. The distribution of impaired loci is captured by the Locus Preservation Hypothesis which suggests that specific parts of the language faculty are immune to impairment across developmental disorders. Through the Locus Preservation Hypothesis, a classical chicken and egg question can be addressed: Do poor conceptual resources and memory limitations result in an atypical grammar or does a grammatical breakdown lead to conceptual and memory limitations? Overall, certain morphological markers reveal themselves as highly susceptible to impairment, while syntactic operations are preserved, granting support to the first scenario. The origin of resilient syntax is explained from a phylogenetic perspective in connection to the “syntax-before-phonology” hypothesis. (shrink)

This study contributes to the cross-linguistic investigation of written language difficulties in children with DLD by reporting new findings from Greek-speaking individuals. Specifically, we investigate the writing performance of children with DLD and compare it to that of a group of typically developing children, matched for gender and chronological age. The specific orthographic properties of Greek, radically different from those of English, offer a unique opportunity to understand the nature of written language production in DLD. The participants of (...) the study were 62 children, 31 with DLD and 31 TD. Both groups were asked to write a text on a special prompt they were given by the researcher and they were assessed in the total number of words used in text, in the proportion of incorrectly spelt words in text as well as in the use of verbs, nouns, content and function words. Also, the different words and the total number of main and subordinate clauses each of the participants used in their text were counted. The findings of the study showed that the written outputs of the DLD group were poorer in almost all measurements compared to those of their TD peers. We discuss our findings in relation to those reported by other languages, in particular English, and spell out the implications for assessing written language in children with DLD. (shrink)

Visual Agnosia is a comprehensive and up-to-date review of disorders of higher vision that relates these disorders to current conceptions of higher vision from cognitive science, illuminating both the neuropsychological disorders and the nature of normal visual object recognition.Brain damage can lead to selective problems with visual perception, including visual agnosia the inability to recognize objects even though elementary visual functions remain unimpaired. Such disorders are relatively rare, yet they provide a window onto how the normal brain might accomplish the (...) complex task of vision. Visual Agnosia reviews a century of case studies of higher-level visual deficits following brain damage, places them in the general context of current neuroscience, and draws relevant conclusions about the organization of normal visual processing. It is unique in drawing on research in cognitive psychology, computational vision, visual neurophysiology, and neuropsychology to interpret the agnosias and draw inferences from them about visual object recognition.Following a historical account of agnosia research, Visual Agnosia offers a taxonomy of a wide range of agnosia syndromes, describing and interpreting the syndromes in terms of the latest theoretical models of visual processing and ultimately bringing them to bear as evidence on a variety of questions in the study of higher vision.Martha J. Farah is Associate Professor of Psychology at Carnegie Mellon University. Visual Agnosia is included in the Issues in Biology of Language and Cognition series, edited by John Marshall. (shrink)

The papers collected in this volume exemplify some of the trends in current approaches to logic, language and computation. Written by authors with varied academic backgrounds, the contributions are intended for an interdisciplinary audience. The first part of this volume addresses issues relevant for multi-agent systems: reasoning with incomplete information, reasoning about knowledge and beliefs, and reasoning about games. Proofs as formal objects form the subject of Part II. Topics covered include: contributions on logical frameworks, linear logic, and different (...) approaches to formalized reasoning. Part III focuses on representations and formal methods in linguistic theory, addressing the areas of comparative and temporal expressions, modal subordination, and compositionality. (shrink)
