Personality traits and endocrine response as possible asymmetry factors of agonistic outcome in karate athletes

Individual variations of plasma levels of hormones testosterone (T) and cortisol (C), before (pre) and after (post) Kumite (real fight) and Kata (ritualized fight) were measured in male karate athletes and analyzed in relation with the agonistic outcome (i.e. winning or losing the fight) and personality trait measures. T and C increased only during Kumite contest and pre‐ and post‐competition C levels were higher in losers than winners. Losers showed higher levels of harm avoidance and anxiety as well as lower level of novelty seeking than winners. Importantly, novelty seeking negatively correlates with pre C and the higher the level of risk assessment, emotionality and insecurity indexes the higher the pre C level. In conclusion, personality traits might be an important factor asymmetry between athletes influencing both the probability of winning or losing an agonistic interaction and the different anticipatory endocrine response to the incipient fight.

Intermodal sensory image generation: An fMRI analysis

Although both imagery and perception may be related to more than one sensory input, and information coming from different sensory channels is often integrated in a unique mental representation, most recent neuroimaging literature has focused on visual imaging. Contrasting results have been obtained concerning the sharing of the same mechanisms by visual perception and visual imagery, in part due to assessment techniques and to interindividual variability in brain activation. In recent years, an increasing number of researchers have adopted novel neuroimaging techniques in order to investigate intermodal connections in mental imagery and have reported a high degree of interaction between mental imagery and other cognitive functions. In the present study the specific nature of mental imagery was investigated by means of fMRI on a more extensive set of perceptual experiences (shapes, sounds, touches, odours, flavours, self‐perceived movements, and internal sensations). Results show that the left middle‐inferior temporal area is recruited by mental imagery for all modalities investigated and not only for the visual one, while parietal and prefrontal areas exhibit a more heterogeneous pattern of activation across modalities. The prominent left lateralisation observed for almost all the conditions suggests that verbal cues affect the processes underlying the generation of images.     

Long- and short-term plastic modeling of action prediction abilities in volleyball

Athletes show superior abilities not only in executing complex actions, but also in anticipating others' moves. Here, we explored how visual and motor experiences contribute to forge elite action prediction abilities in volleyball players. Both adult athletes and supporters were more accurate than novices in predicting the fate of volleyball floating services by viewing the initial ball trajectory, while only athletes could base their predictions on body kinematics. Importantly, adolescents assigned to physical practice training improved their ability to predict the fate of the actions by reading body kinematics, while those assigned to the observational practice training improved only in understanding the ball trajectory. The results suggest that physical and observational practice might provide complementary and mutually reinforcing contributions to the superior perceptual abilities of elite athletes. Moreover, direct motor experience is required to establish novel perceptuo-motor representations that are used to predict others' actions ahead of realization.     

How Diverse Is This Community? Sense of Community,Ethnic Prejudice and Perceived Ethnic Heterogeneity

In this paper, the relationship between territorial sense of community (SoC), perceived ethnic heterogeneity within the community and ethnic prejudice was analyzed. Specifically, the moderating role of perceived ethnic heterogeneity within the community on the SoC–prejudice relationship was tested in a sample of residents (N = 603) of the Salento region, Italy. Results showed that the relationship between SoC and prejudice was moderated by perceived contextual heterogeneity. For blatant and subtle prejudice, when perceived ethnic heterogeneity was low, SoC was negatively associated with prejudice. In the case of modern prejudice, SoC was positively associated with prejudice when perceived ethnic heterogeneity was high. Copyright © 2016 John Wiley & Sons, Ltd.     

Myth,identity and belonging: The Rishi of Bengal/Bangladesh

This essay discusses the politics and relevance of myth and myth making in relation to the subordination of Untouchables in South Asia. Through the case study of one particular group e the Muchi-Rishi of Bengal/ Bangladesh, traditionally skinners, leather-workers and musicians e it is argued that ex-Untouchables do not share the ideology of caste which places them on the lowest echelon of society. This is in contrast with the case of ‘Untouchable myths of origin’ offered by anthropological research (Michael Moffatt, Robert Delie`ge) in South India, Tamil Nadu. However, another set of counter-myths recounted by the Rishi, centred around the figure of Ruidas, offers an alternative which allows them to gain a self-ascribed identity. Far from engaging in a ‘theological’ struggle, the idiom of religion and myth becomes for these ‘ex- Untouchables' and subaltern groups a ‘place of resistance’ from which they can hope to better themselves also in the economic, social and political spheres, as part of their overall endeavour to achieve full human dignity. For some Rishi, this process has taken the form of a long journey from being defined an ‘Untouchable’ to becoming a Dalit.

Impaired configural body processing in anorexia nervosa: Evidence from the body inversion effect

Patients with anorexia nervosa (AN) suffer from severe disturbances of body perception. It is unclear, however, whether such disturbances are linked to specific alterations in the processing of body configurations with respect to the local processing of body part details. Here, we compared a consecutive sample of 12 AN patients with a group of 12 age‐, gender‐ and education‐matched controls using an inversion effect paradigm requiring the visual discrimination of upright and inverted pictures of whole bodies, faces and objects. The AN patients presented selective deficits in the discrimination of upright body stimuli, which requires configural processing. Conversely, patients and controls showed comparable abilities in the discrimination of inverted bodies, which involves only detail‐based processing, and in the discrimination of both upright and inverted faces and objects. Importantly, the body inversion effect negatively correlated with the persistence scores at the Temperament and Character Inventory, which evaluates increased tendency to convert a signal of punishment into a signal of reinforcement. These results suggest that the deficits of configural processing in AN patients may be associated with their obsessive worries about body appearance and to the excessive attention to details that characterizes their general perceptual style.
