Resumen de Mecanismos y bases electrofisiológicas de la atención involuntaria
According to the reorienting hypothesis (Posner & Cohen, 1985), both the facilitatory and IOR effect are explained by the same mechanism: engagement and disengagement of attention, respectively. This disengagement of attention has been considered a necessary and sufficient condition for IOR to be observed (see Klein, 2000, for a review). However, some researchers have recently shown that disengaging attention might be neither necessary nor sufficient for the IOR effect to be observed (see Lupiáñez, 2010, for a review). Therefore, a theoretical explanation of exogenous cueing effects in general and IOR in particular is awaiting.
