“…Post-hoc tests revealed that this main effect was driven by higher posterior alpha power in the Auditory condition as compared to the Visual and Audio-Visual conditions (Tukey HSD, both p < .01, d = .55 and .67 respectively). As previous experiments had implicated alpha activity in selective ignoring of task-irrelevant information (Foxe, Simpson, & Ahlfors, 1998; Gomez-Ramirez et al, 2007; Mathewson et al, 2009; Snyder & Foxe, 2010; Payne & Sekuler, 2014), the continuous posterior alpha activity seen during Auditory trials is likely a marker of the suppression of visual input, perhaps so as to advantage auditory input.…”

Cortical alpha oscillations (8–13 Hz) appear to play a role in suppressing distractions when just one sensory modality is being attended, but do they also contribute when attention is distributed over multiple sensory modalities? For an answer, we examined cortical oscillations in human subjects who were dividing attention between auditory and visual sequences. In Experiment 1, subjects performed an oddball task with auditory, visual, or simultaneous audiovisual sequences in separate blocks, while the electroencephalogram was recorded using high-density scalp electrodes. Alpha oscillations were present continuously over posterior regions while subjects were attending to auditory sequences. This supports the idea that the brain suppresses processing of visual input in order to advantage auditory processing. During a divided-attention audiovisual condition, an oddball (a rare, unusual stimulus) occurred in either the auditory or the visual domain, requiring that attention be divided between the two modalities. Fronto-central theta band (4–7 Hz) activity was strongest in this audiovisual condition, when subjects monitored auditory and visual sequences simultaneously. Theta oscillations have been associated with both attention and with short-term memory. Experiment 2 sought to distinguish these possible roles of fronto-central theta activity during multisensory divided attention. Using a modified version of the oddball task from Experiment 1, Experiment 2 showed that differences in theta power among conditions were independent of short-term memory load. Ruling out theta’s association with short-term memory, we conclude that fronto-central theta activity is likely a marker of multisensory divided attention.

“…Gomez-Ramirez et al (2007) measured electroencephalographic (EEG) response during rest and after 250 mg of L-theanine, and found L-theanine related increased anticipatory alpha band activity over parietal and occipital scalp regions, suggesting reduced arousal states and potentially enhanced effortful control of attention.…”

“…This study aimed to expand on prior research in selective attention which had shown that alpha-band power increases index the degree of attentional suppression in visuospatial attention tasks (Worden et al, 2000; Sauseng et al, 2005; Yamagishi et al, 2005; Kelly et al, 2006, 2009, 2010; Thut et al, 2006; Rihs et al, 2007; Gomez-Ramirez et al, 2009), intersensory attention tasks (Foxe et al, 1998; Fu et al, 2001; Gomez-Ramirez, et al, 2007), sustained visual attention tasks (Dockree et al, 2007; O’Connell et al, 2009) and audiospatial attention tasks (Kerlin et al, 2010; Banerjee et al, in press). We asked if alpha-band mediated suppression would be observed in a feature-based selective attention task.…”

Evidence indicates that when one feature of an object is specifically attended, other task-irrelevant features of that object also receive enhanced processing, presumably as a result of automatic binding processes. On the other hand, evidence also shows that attention can be selectively biased in favor of processing one feature at the expense of processing others. Thus, binding invokes combinatorial processing of related features whereas selective attention emphasizes differential processing. We hypothesized that binding and selective feature-based attention depend on a common resource and therefore might show interference effects. The current study tested this by manipulating binding demands while human participants directed their attention to the color or motion of moving random dot stimuli. Response time measures showed that effects of biased attention were reduced when binding demands were increased. This finding supports the thesis that binding relies, at least in part, upon the same mechanisms invoked by preparatory biasing of selective attention.
