Primary Outcome Measures

Name	Time	Method
<p>The main study parameters of this study will be the differences in NH and HI<br /><br>musicians and non-musicians on behavioral, eye-tracking, pupil dilation and EEG<br /><br>responses, and the individual profiles of these groups when the experimental<br /><br>findings across experiments are combined. These include the following:<br /><br><br /><br>* relation between psychoacoustic measures and more higher-level cognitive<br /><br>processes, such as the time course of linguistic processing and listening<br /><br>effort in eye-tracking, pupil dilation and EEG measures<br /><br>* individual differences based on different musical expertise<br /><br>* group differences between different musicians and means of groups of same<br /><br>musical expertise<br /><br>* relations between the collected measures with measures of psychoacoustic<br /><br>sensitivities </p><br>
