Event-related potentials and illusory conjunctions in the time domain

Abstract

(Rapid Serial Visual Presentation, RSVP) can migrate forming a wrong
 combination or illusory conjunction. Several serial and parallel models have
 been proposed to explain the generation of this type of errors. The
 behavioral results fit better the two-stage parallel model than other serial and
 parallel models. However, they have not been studied the
 psychophysiological correlates that distinguish successful bindings from
 Illusory Conjunctions. The goal here is to collect electrophysiological
 records during this task to determine the degree to which they converge with
 the evidence from behavioral results. One RSVP task required to identify the
 only uppercase word in a stream of lowercase words at a rate of 12
 items/sec. As in previous experiments, more intrusions from post-target
 items than from pre-target items were observed. The results from eventrelated
 potentials are also more supportive for the two-stage parallel model
 than for the serial or other parallel models, as reflected in the differential
 waves associated to correct and wrong combinations
