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

Can the Subaltern Listen? Self-determination and the Provisioning of Expertise in Papua New Guinea

Voice is a major concern in contemporary liberal-democratic politics, one that stresses the political importance of speaking (“giving voice,” “speaking up”). But in the Yopno valley of Papua New Guinea, where NGO and government projects are expanding, people’s sense that they are losing control of their future has led them to worry about their capacity to listen, not their capacity to speak. In largely acephalous villages, people’s self-determination seems particularly threatened by their ignorance of the true nature of their own actions. From a perspective in which the antecedents and the consequences of action are deeply unclear—a perspective stressed in the provisioning of expertise prevalent in political discourse—self-determination hinges on listening and gaining the understanding needed to shape one’s future.Anthropolog

The relation between pitch and gestures in a story-telling task

Anecdotal evidence suggests that both pitch range and gestures contribute to the perception of speakers\u2019 liveliness in speech. However, the relation between speakers\u2019 pitch range and gestures has received little attention. It is possible that variations in pitch range might be accompanied by variations in gestures, and vice versa. In second language speech, the relation between pitch range and gestures might also be affected by speakers\u2019 difficulty in speaking the L2. In this pilot study we compare global pitch range and gesture rate in the speech of 3 native Italian speakers, telling the same story once in Italian and twice in English as part of an in-class oral presentation task. The hypothesis tested is that contextual factors, such as speakers\u2019 nervousness with the task, cause speakers to use narrow pitch range and limited gestures; a greater ease with the task, due to its repetition, cause speakers to use a wider pitch range and more gestures. This experimental hypothesis is partially confirmed by the results of this study
