The aims of this study: to improve the behavior of athletes, followed by modified dysfunctional negative emotions during competition, reducing stress and anxiety in biathlon skiing, through mental training. Problem Statement: first testing took place during February: 2015 and second in February 2016. 20 Subjects were aged of 15.05 years for subjects in group I and 20 subjects 15.49 years for subjects in group II. Purpose of Study to determine whether mental training by applying specific techniques may influence certain psychological factors optimizing performance in biathlon ski. Methods: we used a device EmWave2, which is actually a bio-feedback which give us information about physiological indicators of body: heart rate. The system has three levels of consistency: low (red), medium (blue), high (green).

“…This link illustrates that our identified components are part of a cascade of processes taking place in short succession during lexical decision making. As in previous nonlinguistic decision making tasks, the information processing encoded in the early component is broadcasted onto downstream networks for subsequent post-sensory processing and decision making (Diaz et al, 2017;Ratcliff et al, 2009). Attention in particular can play a crucial modulatory role during this interplay and help facilitate the propagation and enhancement of the most diagnostic stimulus features during visual word processing (Ruz and Nobre, 2008).…”

Good reading comprehension is indispensable in many situations including contractbased transactions that have become so prevalent in our everyday lives. People with dyslexia often exhibit impairments in this important cognitive process. Although the effects of italicsa commonly used style for highlighting important content in a range of documentsand font in general, have been explored with behavioural measures, their impact on human brain dynamics remains poorly understood. Here, we used electroencephalography (EEG) to investigate the specific effects of italics in a sentence reading lexical decision task in adult dyslexics and an age matched nondyslexia group. Overall, the performance of dyslexics was worse. Cluster-based event-related potential (ERP) analysis revealed that brain responses within the first 300 ms following the decision stimulus differed in amplitude and spatial distribution between dyslexics and non-dyslexics when processing italicised text. An initial ERP component over occipitotemporal electrode sites started to differ between the groups as early as 167 ms following the onset of short italicised decision words. A subsequent ERP component over centrofrontal electrodes showed differences lasting until about 300 ms post-stimulus onset. Inter-individual amplitude differences in this centrofrontal neural signal were predictive of behavioural performance across participants, further highlighting the role of fast post-sensory linguistic processes in lexical decision making. Crucially, our findings emphasise the importance of choosing font style carefully to optimise word processing and reading comprehension by everyone.

“…Clarification of the neural mechanism behind visual and brain plasticity may lead to therapies that ameliorate diseases affecting vision, and other forms of pathological or age-related visual decline. The study by Diaz et al in this issue of Nature Human Behaviour reports an intriguing finding that contributes to a better understanding of neural mechanisms of VPL 4 .…”

“…Diaz et al addressed the question as to whether perceptual learning in humans occurs due to enhancement in early sensory representations or in later stages of decision-related processing 4 . They used a face versus car categorization task in which subjects were presented with a very blurred picture and were instructed to report whether it was a face or a car.…”
