The purpose of the present study was to determine whether differences between of the OMSAT-3 scales occurred with an international sample of Iranian athletes with various levels of expertise in sport, e.g., qualifiers versus non-qualifiers or medalists versus non-medalists. Durand-Bush, Salmela and Green-Demers (2001) showed how the OMSAT-3 differe...

Subordinate-level category learning recruits neural resources associated with perceptual expertise, including the N250 component of the ERP, a posterolateral negative wave maximal between 230 and 330 ms. The N250 is a relatively late visual ERP and could plausibly be driven by attention to the features of categorized objects. Indeed, it has a laten...

Objectives Expert motor performance of closed skills requires refined monitoring of external visual reference points and internal body signals. The primary objective of this study was to examine whether shooters at different skill can detect performance variations by attending to varied sources of signals. Design A mixed factorial design was used...

This study examined attention allocation in 30 marksmen categorized into 3 skill levels ranging from expert to novice. Each shooter performed 336 shooting trials. Half of the trials were performed under an occluded-vision condition and the rest under regular, unoccluded conditions. Immediately after completion of a random subset of shots (96 trials...

Purpose: Changes in biophysiological markers related to perceived burnout and self-comfort were tested in this study. Method: Forty-two student-athletes from middle and high school grades were evaluated for burnout, salivary cortisol levels, measures of arousal-related physiological markers (i.e., blood volume pulse; BVP), galvanic skin response (G...

The role of attention in driving perceptual expertise effects is controversial. The current study addressed the effect of training on ERP components related to and independent of attentional feature selection. Participants learned to categorize cartoon animals over six training sessions (8,800 trials) after which ERPs were recorded during a target...

It has long been known that the ventral stream of the visual system contains discrete areas sensitive to object categories, including the Fusiform Face Area (FFA), the Parahippocampal Place Area (PPA) and the Lateral Occipital Complex (LOC). These areas have been well studied using fMRI, but the limited temporal resolution of fMRI has prevented inv...
