A Direct Link between Gaze Perception and Social Attention
Peer reviewed Peer reviewed
Direct linkDirect link
Bayliss, Andrew P.; Bartlett, Jessica; Naughtin, Claire K.; Kritikos, Ada – Journal of Experimental Psychology: Human Perception and Performance, 2011
How information is exchanged between the cognitive mechanisms responsible for gaze perception and social attention is unclear. These systems could be independent; the "gaze cueing" effect could emerge from the activation of a general-purpose attentional mechanism that is ignorant of the social nature of the gaze cue. Alternatively, orienting to…

Bottom-Up Guidance in Visual Search for Conjunctions
Peer reviewed Peer reviewed

Proulx, Michael J. – Journal of Experimental Psychology: Human Perception and Performance, 2007
Understanding the relative role of top-down and bottom-up guidance is crucial for models of visual search. Previous studies have addressed the role of top-down and bottom-up processes in search for a conjunction of features but with inconsistent results. Here, the author used an attentional capture method to address the role of top-down and…

The Suppression of Reflexive Visual and Auditory Orienting when Attention Is Otherwise Engaged
Peer reviewed Peer reviewed

Santangelo, Valerio; Olivetti Belardinelli, Marta; Spence, Charles – Journal of Experimental Psychology: Human Perception and Performance, 2007
Two experiments were conducted to examine whether abrupt onsets are capable of reflexively capturing attention when they occur outside the current focus of spatial attention, as would be expected if exogenous orienting operates in a truly automatic fashion. The authors established a highly focused attentional state by means of the central…

The Attentional White Bear Phenomenon: The Mandatory Allocation of Attention to Expected Distractor Locations
Peer reviewed Peer reviewed
Direct linkDirect link
Tsal, Yehoshua; Makovski, Tal – Journal of Experimental Psychology: Human Perception and Performance, 2006
The authors devised a prestimulus-probe method to assess the allocation of attention as a function of participants' top-down expectancies concerning distractor and target locations. Participants performed the flanker task, and distractor locations remained fixed. On some trials, instead of the flanker display, either 2 simultaneous dots or a…

Rhythmic Masking Release: Effects of Asynchrony, Temporal Overlap, Harmonic Relations, and Source Separation on Cross-Spectral Grouping
Peer reviewed Peer reviewed

Turgeon, Martine; Bregman, Albert S.; Roberts, Brian – Journal of Experimental Psychology: Human Perception and Performance, 2005
The rhythm created by spacing a series of brief tones in a regular pattern can be disguised by interleaving identical distractors at irregular intervals. The disguised rhythm can be unmasked if the distractors are allocated to a separate stream from the rhythm by integration with temporally overlapping captors. Listeners identified which of 2…

Task Demands Control Acquisition and Storage of Visual Information
Peer reviewed Peer reviewed

Droll, Jason A.; Hayhoe, Mary M.; Triesch, Jochen; Sullivan, Brian T. – Journal of Experimental Psychology: Human Perception and Performance, 2005
Attention and working memory limitations set strict limits on visual representations, yet researchers have little appreciation of how these limits constrain the acquisition of information in ongoing visually guided behavior. Subjects performed a brick sorting task in a virtual environment. A change was made to 1 of the features of the brick being…
