Electrophysiological Indices of Target and Distractor Processing in Visual Search by Hickey, Clayton, Di Lollo, Vincent, McDonald, John J

“…Attentional selection of a target presented among distractors can be indexed with an event-related potential (ERP) component known as the N2pc. Theoretical…”

Attentional enhancement predicts individual differences in visual working memory under go/no-go search conditions by Tay, Daniel, McDonald, John J

“…Attention-control processes transfer relevant information to visual working memory (WM) and prevent irrelevant information from consuming WM resources…”

Inability to suppress salient distractors predicts low visual working memory capacity by Gaspar, John M., Christie, Gregory J., Prime, David J., Jolicœur, Pierre, McDonald, John J.

“…According to contemporary accounts of visual working memory (vWM), the ability to efficiently filter relevant from irrelevant information contributes to an…”

Electrophysiological evidence of the capture of visual attention by Hickey, Clayton, McDonald, John J, Theeuwes, Jan

“…We investigated the ability of salient yet task-irrelevant stimuli to capture attention in two visual search experiments. Participants were presented with…”

Sounds activate visual cortex and improve visual discrimination by Feng, Wenfeng, Störmer, Viola S, Martinez, Antigona, McDonald, John J, Hillyard, Steven A

“…A recent study in humans (McDonald et al., 2013) found that peripheral, task-irrelevant sounds activated contralateral visual cortex automatically as revealed…”

Rhythms of consciousness: binocular rivalry reveals large-scale oscillatory network dynamics mediating visual perception by Doesburg, Sam M, Green, Jessica J, McDonald, John J, Ward, Lawrence M

“…Consciousness has been proposed to emerge from functionally integrated large-scale ensembles of gamma-synchronous neural populations that form and dissolve at…”

Cross-modal cueing of attention alters appearance and early cortical processing of visual stimuli by Störmer, Viola S, McDonald, John J, Hillyard, Steven A

“…The question of whether attention makes sensory impressions appear more intense has been a matter of debate for over a century. Recent psychophysical studies…”

Electrical Neuroimaging Reveals Timing of Attentional Control Activity in Human Brain by Green, Jessica J, McDonald, John J

“…Voluntarily shifting attention to a location of the visual field improves the perception of events that occur there. Regions of frontal cortex are thought to…”

From local inhibition to long-range integration: A functional dissociation of alpha-band synchronization across cortical scales in visuospatial attention by Doesburg, Sam M, Green, Jessica J, McDonald, John J, Ward, Lawrence M

“…Abstract When attention is allocated to one visual hemifield, increased alpha power is observed in ipsilateral visual cortex. This has been attributed to…”

Electrical neuroimaging of voluntary audiospatial attention: evidence for a supramodal attention control network by Green, Jessica J, Doesburg, Sam M, Ward, Lawrence M, McDonald, John J

“…Previous attempts to investigate the supramodal nature of attentional control have focused primarily on identifying neuroanatomical overlap in the…”

Proactive and reactive processes in the medial frontal cortex: an electrophysiological study by Oliveira, Flavio T P, Hickey, Clayton, McDonald, John J

“…The posterior medial frontal cortex (pMFC) is known to be involved in adaptive goal-directed behavior, but its specific function is not yet clear. Most…”

Neural basis of auditory-induced shifts in visual time-order perception by McDonald, John J, Teder-Sälejärvi, Wolfgang A, Di Russo, Francesco, Hillyard, Steven A

“…Attended objects are perceived to occur before unattended objects even when the two objects are presented simultaneously. This finding has led to the…”

Revisiting the Automaticity of Reading: Electrophysiological Recordings Show That Stroop Words Capture Spatial Attention by Lowery, Andrew, McDonald, John J.

“…Interference in the Stroop task is reduced when the word and color patch are placed at different locations and is diluted further by the presence of another…”

Individual differences in rate of encoding predict estimates of visual short-term memory capacity (K) by Jannati, Ali, McDonald, John J, Di Lollo, Vincent

“…The capacity of visual short-term memory (VSTM) is commonly estimated by K scores obtained with a change-detection task. Contrary to common belief, K may be…”

Inhibition of return in the covert deployment of attention: evidence from human electrophysiology by McDonald, John J, Hickey, Clayton, Green, Jessica J, Whitman, Jennifer C

“…People are slow to react to objects that appear at recently attended locations. This delay-known as inhibition of return (IOR)-is believed to aid search of the…”
