Neglect between but not within auditory objects.
Unilateral neglect is frequently characterized by the presence of extinction, which is a lack of awareness to contralesional visual stimuli in the presence of those further towards the ipsilesional side. It has been established that this visual extinction can be reduced if the stimuli are grouped together into a single object. However, attention between and within auditory objects has never bef...
متن کاملAttentional capture within and between objects.
The present study addressed the question whether attentional capture by abrupt onsets is affected by object-like properties of the stimulus field. Observers searched for a target circle at one of four ends of two solid rectangles. In the focused attention condition the location of the upcoming target was cued by means of a central arrowhead, whereas in the divided attention condition, the targe...
متن کاملDo prosopagnosics have impaired spatial coding within or between objects?
Barton and Cherkasova (2005) tested within-object and between-object spatial abilities of patients with prosopagnosia and concluded that prosopagnosia is the result of within-object spatial impairment. The interpretation of these findings is difficult as Barton and Cherkasova’s (2005) experimental design involved a major confound of using smaller distances in the within-object task and larger d...
متن کاملTopological Relations between Random Areal Objects within GIS
ABSTRACT There is inevitably error or uncertainty in spatial data, which are used to represent reality world, it will causes a suspicion for correctness of topological relations obtained by reasoning from observation data. In this paper, we firstly describe the geometric and statistical properties of areal object, and analyzing the effects of positional uncertainty on representation of topologi...
متن کاملWithin and cross dimensions 1 Running Head: WITHIN AND CROSS DIMENSIONS Response Selection modulates Visual Search Within And Across Dimensions
In feature search tasks, uncertainty about the dimension on which targets differ from the surrounding nontargets hampers search performance relative to a situation in which this dimension is known in advance. Typically these cross-dimensional costs are associated with less efficient guidance of attention to the target. In the present study participants either had to perform a visual search task...
