EEG phase synchronization analysis applied to the attentional blink phenomenon
The attentional blink (AB) phenomenon was investigated using dynamic cross-lag phase synchronization of scalp EEG. We hypothesized that long-distance phase synchronization of gamma-band scalp EEG is necessary for conscious report of two targets in RSVP. To test the hypothesis, a dynamic cross-lag phase synchronization index (dcPSI) was computed for 45 pairs of electrodes. The dcPSI is a robust ...
متن کاملAlpha entrainment is responsible for the attentional blink phenomenon
The attentional blink phenomenon is the reduced ability to report a second target (T2) after identifying a first target (T1) in a rapid serial visual presentation (RSVP) of stimuli (e.g., letters), which are presented at approximately 10 items per second. Several explanations have been proposed, which focus primarily on cognitive aspects, such as attentional filter-, capacity limitation- and re...
متن کاملIs consciousness a gradual phenomenon? Evidence for an all-or-none bifurcation during the attentional blink.
Several theories of the neural correlates of consciousness assume that there is a continuum of perception, associated with a gradual change in the intensity of brain activation. But some models, considering reverberation of neural activity as necessary for conscious perception, predict a sharp nonlinear transition between unconscious and conscious processing. We asked participants to evaluate t...
متن کاملTemporal dynamics of access to consciousness in the attentional blink
Presentation of two targets in close temporal succession often results in an impairment of conscious perception for the second stimulus. Previous studies have identified several electrophysiological correlates for this so-called 'attentional blink'. Components of the event-related potential (ERP) such as the N2 and the P3, but also oscillatory brain signals have been shown to distinguish betwee...
متن کاملThe attentional blink is not a unitary phenomenon.
Identification of the second of two targets is impaired if it is presented less than about 500 ms after the first. Three models of this second-target deficit, known as attentional blink (AB), were compared: resource-depletion, bottleneck, and temporary loss of control (TLC). Five experiments, in which three sequential targets were inserted in a stream of distractors, showed that identification ...
