Perceived Simultaneity and Temporal Order of Audiovisual Events Following Concussion.

摘要: The central nervous system allows for a limited time span referred to as the temporal binding window (TBW) in order rapidly determine whether multisensory events correspond with same event. Failure correctly identify occur simultaneously and their sequential can lead inaccurate representations of physical world, poor decision-making dangerous behavior. Damage neural systems that coordinate relative timing sensory may explain some long-term consequences associated concussion. aim this study was investigate perception simultaneity discrimination audiovisual stimuli are impaired those history Fifty participants (17 concussion history) were recruited complete judgment (SJ) (TOJ) tasks. From these tasks, TBW point subjective (PSS) extracted assess precision or accuracy changes concussion, respectively. Results demonstrated have significantly wider (less precise), no significant change PSS (no accuracy), particularly TOJ task but differences found between SJ Importantly, negative correlation elapsed since last width suggests does improve over time. These findings suggest display an impairment perceived monitoring performance tasks be useful additional assessment tool when making decisions about returning regular work play following
