Evidence against a central bottleneck during the attentional blink: multiple channels for configural and featural processingEdward Awh
Department of Psychology, 1227 University of Oregon, Eugene, OR 97403 1227, USA
Cogn Psychol 48:95-126. 2004..These results suggest that all stimuli do not compete for access to a single resource for visual perception. We propose a multi-channel account of interference in the AB paradigm...- Top-down control over biased competition during covert spatial orientingEdward Awh

University of Oregon, Eugene 97403 1227, USA
Psychol Sci 12:329-34. 2001..The latter effect replicates the initial evidence in favor of object-based selection, and can be demonstrated even when the relevant targets are cued after the offset of the target stimuli... - Evidence for split attentional fociE Awh
Department of Psychology, University of Oregon, Eugene 97403 1227, USA
J Exp Psychol Hum Percept Perform 26:834-46. 2000..Experiments 4 and 4a suggest that the primary mechanism supporting the flexible deployment of spatial attention is the suppression of interference from stimuli at unattended locations... - The anterior cingulate cortex lends a hand in response selectionE Awh
Edward Awh is in the Department of Psychology, 1227 University of Oregon, Eugene, Oregon 97403, USA
Nat Neurosci 2:853-4. 1999..The anterior cingulate cortex is involved in decisions between conflicting response tendencies. This executive function seems to involve separate pathways for manual and verbal responses... - Resolving visual interference during covert spatial orienting: online attentional control through static records of prior visual experienceEdward Awh
Department of Psychology, University of Oregon, Eugene, 97403, USA
J Exp Psychol Gen 134:192-206. 2005..Thus, static probability maps can provide an internal template that guides the resolution of visual interference as spatial attention traverses the visual field... - Perceptual expertise enhances the resolution but not the number of representations in working memoryMiranda Scolari
University of Oregon, Eugene, OR, USA
Psychon Bull Rev 15:215-22. 2008..These results clarify the effects of perceptual expertise in working memory and support recent suggestions that number and resolution represent distinct facets of working memory ability... - Rehearsal in spatial working memoryE Awh
Department of Psychology, University of California, San Diego, La Jolla 92093, USA
J Exp Psychol Hum Percept Perform 24:780-90. 1998..It is argued that these results implicate selective spatial attention as a rehearsal mechanism for spatial working memory... - Visual working memory represents a fixed number of items regardless of complexityEdward Awh
University of Oregon, Eugene, OR 97403 1227, USA
Psychol Sci 18:622-8. 2007..Finally, a correlational analysis suggested a two-factor model of working memory ability, in which the number and resolution of representations in working memory correspond to distinct dimensions of memory ability... - Spatial attention, preview, and popout: which factors influence critical spacing in crowded displays?Miranda Scolari
Department of Psychology, University of Oregon, Eugene, OR, USA
J Vis 7:7.1-23. 2007..These disparate results indicate that attention improves target discrimination in crowded displays in a qualitatively different manner than do the other factors... 
The elusive link between conflict and conflict adaptationUlrich Mayr
Department of Psychology, University of Oregon, Eugene, OR 97403 1227, USA
Psychol Res 73:794-802. 2009..Based on the evidence of a weak link between conflict and conflict adaptation, we argue that a wider range of possible reasons for conflict adaptation effects needs to be taken into consideration...
Discrete resource allocation in visual working memoryBrian Barton
Department of Psychology, University of Oregon, Eugene, OR 97403, USA
J Exp Psychol Hum Percept Perform 35:1359-67. 2009..Thus, resources in visual working memory are distributed in a discrete slot-based fashion, even when interitem variations in complexity motivate an asymmetrical division of resources across items...- The bouncer in the brainEdward Awh
Department of Psychology, University of Oregon, Eugene, OR 97403 1227, USA
Nat Neurosci 11:5-6. 2008..A new functional imaging study suggests that the basal ganglia act as this filter because activity in this region before stimulus presentation was inversely correlated with unnecessary storage... - Conflict adaptation effects in the absence of executive controlUlrich Mayr
Department of Psychology, University of Oregon, Eugene, Oregon 97403, USA
Nat Neurosci 6:450-2. 2003 - PET evidence for an amodal verbal working memory systemE H Schumacher
Department of Psychology, University of Michigan, Ann Arbor 48109, USA
Neuroimage 3:79-88. 1996..These results correspond well with previous research and suggest that verbal working memory is modality independent and is mediated by a circuit involving frontal, parietal, and cerebellar mechanisms... - Interactions between attention and working memoryE Awh
University of Oregon, Eugene, OR 97403, USA
Neuroscience 139:201-8. 2006..Thus, although it is clear that these processes are closely intertwined, the nature of these interactions depends upon the specific variety of attention or working memory that is considered... - Visual and oculomotor selection: links, causes and implications for spatial attentionEdward Awh
Department of Psychology, University of Oregon, 1227 University of Oregon, Eugene, OR 97403-1227, USA
Trends Cogn Sci 10:124-30. 2006..Taken together, all of the recent work suggests how visual and oculomotor signals are integrated to simultaneously select the visual attributes of targets and the saccades needed to fixate them... - Experience-dependent changes in the topography of visual crowdingKRISTIN WILLIAMSON
Department of Psychology, University of Oregon, Eugene, OR, USA
J Vis 9:15.1-9. 2009.... - Spatially global representations in human primary visual cortex during working memory maintenanceEdward F Ester
