Representing Indian Philosophy Through the Nation: an Exploration of the Public Philosopher Radhakrishnan

Several authors working on cross-cultural philosophy underscore that a cross-cultural conversational space, which breaks away from dominant theoretical frameworks, is necessary for a genuine cross-cultural dialog. This paper too seeks to contribute to the development of such a space. To this end, its focus will lie on one salient representation of Indian philosophy in the postcolonial context: the ‘Report of the University Education Commission’ of 1948–1949 (Report 1950). The paper will analyze how this document marries shared values like freedom and equality with the role of philosophy for the Indian nation.     

Direct and indirect effects of parenting practices on socio‐moral approval of aggression in Polish young adults. Do all practices matter?

The purpose of this article was to determine the socialisation antecedents of socio‐moral approval of aggression (SMAA). In Study 1, we assessed factorial structure and reliability of the SMAA with a sample of 355 students who reported on the extent to which they approved of six forms of aggressive behaviour and six justifications of aggression. Two‐factor solutions were obtained with regard to forms and justifications of aggressive acts. Thus, approval of extreme and minor aggression was distinguished as well as legitimate and illegitimate justifications of aggression. In Study 2, we tested the path models of the socialisation antecedents that contributed to the high approval of minor and extreme aggressive acts as well as legitimate and illegitimate justifications of aggression. Data were collected from 173 undergraduate students. Path analyses showed that high levels of approval of extremely aggressive acts and of illegitimate justifications of aggression were preceded by a sequence of negative life events, beginning with frequent misbehaviour in childhood, corporal punishment used by parents and ending with delinquency in adolescence. The approval of minor aggression had little relation to socialisation factors apart from a detrimental effect of psychological aggression while approval of legitimate justifications of aggression had no socialisation antecedents.     

Multi- and unisensory decoding of words and nonwords result in differential brain responses in dyslexic and nondyslexic adults

The present functional magnetic resonance imaging (fMRI) study was designed, in order to investigate the neural substrates involved in the audiovisual processing of disyllabic German words and pseudowords. Twelve dyslexic and 13 nondyslexic adults performed a lexical decision task while stimuli were presented unimodally (either aurally or visually) or bimodally (audiovisually simultaneously).The behavioral data collected during the experiment evidenced more accurate processing for bimodally than for unimodally presented stimuli irrespective of group. Words were processed faster than pseudowords. Notably, no group differences have been found for either accuracy or for reaction times. With respect to brain responses, nondyslexic compared to dyslexic adults elicited stronger hemodynamic responses in the leftward supramarginal gyrus (SMG), as well as in the right hemispheric superior temporal sulcus (STS). Furthermore, dyslexic compared to nondyslexic adults showed reduced responses to only aurally presented signals and enhanced hemodynamic responses to audiovisual, as well as visual stimulation in the right anterior insula.Our behavioral results evidence that the two groups easily identified the two-syllabic proper nouns that we provided them with. Our fMRI results indicate that dyslexics show less neuronal involvement of heteromodal and extrasylvian regions, namely, the STS, SMG, and insula when decoding phonological information. We posit that dyslexic adults evidence deficient functioning of word processing, which could possibly be attributed to deficits in phoneme to grapheme mapping. This problem may be caused by impaired audiovisual processing in multimodal areas.     

Proprioception plays a different role for sensorimotor adaptation to different distortions

If proprioceptive feedback is degraded by agonist-antagonist muscle vibration, then adaptation to rotated vision remains intact while adaptation to a velocity-dependent force field worsens. Here we evaluate whether this differential effect of vibration is related to the physical nature of the distortion - visual versus mechanical - or to their kinematic coupling to the subjects’ hand - velocity versus position dependent. Subjects adapted to a velocity-dependent visual distortion, to a position-dependent force, or to a velocity-dependent force; one half of the subjects adapted with, and the other half without agonist-antagonist vibration at the wrist, elbow, and shoulder. We found, as before, that vibration slowed down adaptation to a velocity-dependent force. However, vibration did not modify adaptation to the other two distortions, nor did it influence the aftereffects of any distortion. From this we conclude that intact proprioception supports strategic compensatory processes when proprioceptive signals agree with visual ones, and provide relevant (dynamic) information not available to the visual system.     

The role of anxiety and perspective-taking strategy on affective empathic responses

Empathy is an important pro-social behaviour critical to a positive client–therapist relationship. Therapist anxiety has been linked to reduced ability to empathise and lower client satisfaction with therapy. However, the nature of the relationship between anxiety and empathy is currently unclear. The current study investigated the effect of experimentally-induced anxiety on empathic responses elicited during three different perspective-taking tasks. Perspective-taking was manipulated within-subjects with all participants (N = 52) completing imagine-self, imagine-other and objective conditions. A threat of shock manipulation was used to vary anxiety between-subjects. Participants in the threat of shock condition reported higher levels of anxiety during the experiment and lower levels of empathy-related distress for the targets than participants in the control condition. Perspective-taking was associated with higher levels of empathy-related distress and concern compared to the objective condition. The present results suggest that perspective-taking can to a large extent mitigate the influence of heightened anxiety on an individual’s ability to empathise.     

The neurobiology of the stress-resistant brain

The 2010 Neurobiology of Stress Workshop brought together scientists from all over the world to share and discuss their results from studies examining the consequences of acute, repeated, and chronic stressor exposure on health and disease. Session IV entitled "The neurobiology of the stress-resistant brain" explored how we can intervene to promote stress resistance and stress resilience. Four scientists, who explore this topic from unique and convergent perspectives, presented their experimental results derived from studies in rat (Fleshner and Maier), non-human primates (Lyons), and human (Raskind). Summaries of each presentation, supporting publications, and overall take-home messages from the session are presented.
