Spatial cuing in a stereoscopic display: Evidence for a “depth-blind” attentional spotlight

TLDR
The results suggest that spatial selection in spatial cuing tasks operates on a representation that does not include depth information.Abstract:
This experiment explored whether attentional selection observed in a spatial cuing task is based on a representation that includes depth information or not. Targets were presented inside placeholders appearing at the samex,y location on a stereoscopic display, but on different depth planes, or at differentx,y locations on the same depth plane. A peripheral precue produced significant cuing effects in the latter but not in the former condition. In a control experiment, significant cuing effects were found for targets appearing at differentx,y coordinates within the fovea, confirming that the lack of cuing effects in the depth condition was not due to foveal presentation. Together, the results suggest that spatial selection in spatial cuing tasks operates on a representation that does not include depth information.read more

Object-Based Attention and Occlusion Evidence From Normal Participants and a Computational Model
TL;DR: The object-based attention mechanism as mentioned in this paper groups together those features based on internal representations developed over perceptual experience and then preferentially gates these features for later, selective processing, which is robust even under conditions of occlusion.

Dynamics of attention in depth: evidence from multi-element tracking.
TL;DR: This work shows that depth cues improve performance in a multi-element tracking task in the case where element boundaries are allowed to intersect in the depiction of motion in a single frontoparallel plane and shows that division of attention across two surfaces aids in tracking moving targets.

Flexible visual processing of spatial relationships.
TL;DR: It is demonstrated that shifts of selection do occur during spatial relationship judgments that feel simultaneous, by tracking selection with an electrophysiological correlate, and it is speculated that static structure across space may be encoded as a dynamic sequence across time.

Attention to object files defined by transparent motion.
TL;DR: Two interspersed and differently colored sets of dots were rotated in opposite directions and were perceived as superimposed transparent surfaces that required close spatial proximity of incompatible motion signals to be perceived.

Effects of noise letters upon the identification of a target letter in a nonsearch task
TL;DR: In this paper, a 1-sec tachistoscopic exposure, Ss responded with a right or left leverpress to a single target letter from the sets H and K or S and C. The target always appeared directly above the fixation cross.

Involuntary covert orienting is contingent on attentional control settings.
TL;DR: Four experiments tested a new hypothesis that involuntary attention shifts are contingent on the relationship between the properties of the eliciting event and the properties required for task performance through a variant of the spatial cuing paradigm.

The reviewing of object files: object-specific integration of information.
TL;DR: The concept of anobject file as a temporary episodic representation, within which successive states of an object are linked and integrated, is developed, which develops the concept of a reviewing process, which is triggered by the appearance of the target and retrieves just one of the previewed items.
Journal ArticleDOI
Selective attention and the organization of visual information.
TL;DR: The authors showed that two judgments that concern the same object can be made simultaneously without loss of accuracy, whereas two judgment that concern different objects cannot, neither the similarity nor the difficulty of required discriminations, nor the spatial distribution of information, could account for the results.

Serial and parallel processing of visual feature conjunctions
Ken Nakayama,Gerald H. Silverman +1 more
TL;DR: It seems that the visual system is incapable of conducting a parallel search over two stimulus dimensions simultaneously, but this conclusion is extended for the conjunction of motion and colour, showing that it requires a serial search.
