The functional inhibition account states that alpha-band (8-14 Hz) power implements attentional control by selectively inhibiting task-irrelevant neural representations. This account has been well supported by decades of correlational research showing attention-related changes in the topography of alpha power in anticipation of task-relevant stimul...

A large body of work has linked neural oscillations in the alpha-band (8–13 Hz) to visual perceptual outcomes. In particular, studies have found that alpha phase prior to stimulus onset predicts stimulus detection, and sensory responses and that the frequency of alpha can predict temporal properties of perception. These findings have bolstered the...

Alpha-band (8-13 Hz) oscillations have been shown to phasically inhibit perceptual reports in human observers, yet the underlying physiological mechanism of this effect is debated. According to contrasting models, based primarily on animal experiments, alpha activity is thought to either originate from specialized cells in the visual thalamus and p...

Theories of perception based on discrete sampling posit that visual consciousness is reconstructed based on snapshot‐like perceptual moments, as opposed to being updated continuously. According to a model proposed by Schneider (2018), discrete sampling can explain both the flash‐lag and the Fröhlich illusion, whereby a lag in the conscious updating...

Understanding people when they are speaking seems to be an activity that we do only with our ears. Why, then, do we usually look at the face of the person we are listening to? Could it be that our eyes are also involved in understanding speech? We designed an experiment in which we asked people to try to comprehend speech in different listening con...

The neurogenesis of alpha-band (8-13 Hz) activity has been characterized across many different animal experiments. However, the functional role that alpha oscillations play in perception and behavior has largely been attributed to two contrasting hypotheses, with human evidence in favor of either (or both or neither) remaining sparse. On the one ha...

Speech comprehension is often thought of as an entirely auditory process, but both normal hearing and hearing-impaired individuals sometimes use visual attention to disambiguate speech, particularly when it is difficult to hear. Many studies have investigated how visual attention (or the lack thereof) impacts the perception of simple speech sounds...
