Values provided without distinguishing among conditions are highlighted in bold. Behavioral data (reaction times [RT] and percentage of errors [PE]) are provided differencing between conditions (Compatible Direction-Compatible Position –CDCP- Incompatible Direction-Compatible Position –IDCP- Compatible Direction-Incompatible Position –CDIP- and Incompatible Direction-Incompatible Position -IDIP) as well as averaging across conditions. Latencies (in milliseconds) and amplitudes (in μV) for negativity central-contralateral (N2cc) and negativity posterior-contralateral (N2pc) are also reported.
