Аннотация:In the experimental condition, anticipatory attention is modulated by cue-stimuli that inform participants about relevant characteristics of target stimuli and increase participants' task performance (Spence and Driver 1997, Posner and Fan 2008). However, there is reason to suppose that a regular sequence-based stimuli presentation can form anticipation as well. A multiple repetition of the same stimuli sequence underlies serial learning what results in the improvement of response rate and accuracy for the stimuli of different sensory modalities (Nissen and Bullemer 1987, Conway and Christian- sen 2005, Weiermann and Meier 2012, Boutin et al. 2013). Cleermans et al. (1998) confirmed the possibility of implicit anticipation of an upcoming event. In their study, a regular repetition of image location shifts was shown to make participants not only react faster, but predict the location of visual stimuli as well. Thus, the anticipation can be implicitly caused by the regularity of stimuli presentation and influence positively the performance of subsequent cognitive tasks. We assume that the brain mechanisms underlying the improvement of cognitive task performance are different during implicit and cued anticipation. In order to check this assumption, we conducted EEG analysis of functional interactions between cortical areas in the prestimulus period.
