The philosophical significance of binary categories in Habermas’s discourse ethics

The philosophical programme associated with the discourse ethics of Jürgen Habermas has been widely discussed in the literature. The fact that Habermas has devoted a considerable part of his work to the elaboration of this philosophical programme indicates that discourse ethics can be regarded as a cornerstone of his communication-theoretic approach to society. In essence, Habermas conceives of discourse ethics as a philosophical framework which derives the coordinative power of social normativity from the discursive power of communicative rationality. Although there is an extensive literature on Habermas’s communication-theoretic account of society, almost no attention has been paid to the fact that the theoretical framework which undergirds his discourse ethics is based on a number of binary conceptual divisions. It is the purpose of this paper to shed light on the philosophical significance of these binary categories in Habermas’s discourse ethics and thereby demonstrate that their complexity is indicative of the subject’s tension-laden immersion in social reality

Atypical audiovisual speech integration in infants at risk for autism

The language difficulties often seen in individuals with autism might stem from an inability to integrate audiovisual information, a skill important for language development. We investigated whether 9-month-old siblings of older children with autism, who are at an increased risk of developing autism, are able to integrate audiovisual speech cues. We used an eye-tracker to record where infants looked when shown a screen displaying two faces of the same model, where one face is articulating/ba/and the other/ga/, with one face congruent with the syllable sound being presented simultaneously, the other face incongruent. This method was successful in showing that infants at low risk can integrate audiovisual speech: they looked for the same amount of time at the mouths in both the fusible visual/ga/− audio/ba/and the congruent visual/ba/− audio/ba/displays, indicating that the auditory and visual streams fuse into a McGurk-type of syllabic percept in the incongruent condition. It also showed that low-risk infants could perceive a mismatch between auditory and visual cues: they looked longer at the mouth in the mismatched, non-fusible visual/ba/− audio/ga/display compared with the congruent visual/ga/− audio/ga/display, demonstrating that they perceive an uncommon, and therefore interesting, speech-like percept when looking at the incongruent mouth (repeated ANOVA: displays x fusion/mismatch conditions interaction: F(1,16) = 17.153, p = 0.001). The looking behaviour of high-risk infants did not differ according to the type of display, suggesting difficulties in matching auditory and visual information (repeated ANOVA, displays x conditions interaction: F(1,25) = 0.09, p = 0.767), in contrast to low-risk infants (repeated ANOVA: displays x conditions x low/high-risk groups interaction: F(1,41) = 4.466, p = 0.041). In some cases this reduced ability might lead to the poor communication skills characteristic of autism

Speech and language therapy versus placebo or no intervention for speech problems in Parkinson's disease

Parkinson's disease patients commonly suffer from speech and vocal problems including dysarthric speech, reduced loudness and loss of articulation. These symptoms increase in frequency and intensity with progression of the disease). Speech and language therapy (SLT) aims to improve the intelligibility of speech with behavioural treatment techniques or instrumental aids

Talking the Talk: The Effect of Vocalics in an Interview

Our voices carry more than just content. People continuously make assumptions of one’s intelligence, credibility, personality, and other characteristics merely based on the way we talk. As the diversity of individuals in the workplace increases, so too do the differences in how those individuals talk. It is important that we understand how these different ways of speaking are being perceived in the workplace. More specifically, how are individuals being perceived prior to being hired via the interview process? This Honors Capstone project aims to understand the impact that vocal characteristics in an individual have on the interviewer’s perception of the interviewee, and how that impacts the hiring process. This project will offer professionals of all ages tangible advice on ways to increase one’s chances of receiving a job just by altering aspects of one’s voice

Grammatical errors in spoken english of University students in oral communication course

The present study examines the grammatical errors in spoken English of university students who are less proficient in English. The specific objectives of the study are to determine the types of errors and the changes in grammatical accuracy during the duration of the English for Social Purposes course focussing on oral communication. The language data were obtained from the simulated oral interactions of 42 students participating in five role play situations during the 14-week semester. Error analysis of 126 oral interactions showed that the five common grammar errors made by the learners are preposition, question, article, plural form of nouns, subject-verb agreement and tense. Based on Dulay, Burt and Krashen’s (1982) surface structure taxonomy, the main ways by which students modify the target forms are misinformation and omission, with addition of elements or misordering being less frequent. The results also showed an increase in grammatical accuracy in the students’ spoken English towards the end of the course

Involvement of the cortico-basal ganglia-thalamocortical loop in developmental stuttering

Stuttering is a complex neurodevelopmental disorder that has to date eluded a clear explication of its pathophysiological bases. In this review, we utilize the Directions Into Velocities of Articulators (DIVA) neurocomputational modeling framework to mechanistically interpret relevant findings from the behavioral and neurological literatures on stuttering. Within this theoretical framework, we propose that the primary impairment underlying stuttering behavior is malfunction in the cortico-basal ganglia-thalamocortical (hereafter, cortico-BG) loop that is responsible for initiating speech motor programs. This theoretical perspective predicts three possible loci of impaired neural processing within the cortico-BG loop that could lead to stuttering behaviors: impairment within the basal ganglia proper; impairment of axonal projections between cerebral cortex, basal ganglia, and thalamus; and impairment in cortical processing. These theoretical perspectives are presented in detail, followed by a review of empirical data that make reference to these three possibilities. We also highlight any differences that are present in the literature based on examining adults versus children, which give important insights into potential core deficits associated with stuttering versus compensatory changes that occur in the brain as a result of having stuttered for many years in the case of adults who stutter. We conclude with outstanding questions in the field and promising areas for future studies that have the potential to further advance mechanistic understanding of neural deficits underlying persistent developmental stuttering.R01 DC007683 - NIDCD NIH HHS; R01 DC011277 - NIDCD NIH HHSPublished versio
