- Primary Outcome Measures
Name Time Method Single-trial-alignment of P600 effects to onset of critical (syntactically deviating) word vs. following reaction time will be measured thusly:<br>All participant's single-trial EEG epochs centered around the onset of deviating words will be plotted using ERPimages (Jung et al., 2001) sorted by reaction time (RT). The average of these trials is expected to show a positive deflection peaking approximately 600ms after onset. In RT-sorted ERPimages, stimulus-aligned effects show up as straight vertical lines (parallel to stimulus onset), RT-aligned effects show up as curved, RT-aligned lines.<br>We will investigate centro-parietal electrodes (electrode Pz and its neighbors).
- Secondary Outcome Measures
Name Time Method We will also investigate the onset/RT-alignment of other language-related ERP components (N400, LAN, N2), as well as possible attentional blink phenomena (a second target appearing during the P300 of the previous target) and compare the effects between semantic and syntactic deviations in their scalp topology.
