Spatial attention and eye movements
Experimental Brain Research, 1995We previously showed that when attention is allocated to the right or left of the fixation point, saccades directed to targets located above or below the fixation point deviate contralateral to the attention locus. In the present study, we examined how general this phenomenon is and whether the amount of saccade deviation depends on the location of ...

Programming shifts of spatial attention
European Journal of Cognitive Psychology, 1994Abstract Two experiments are described, which were aimed at studying attention allocation at different times following directional cognitive cue presentation. In Experiment 1, the stimulus display consisted of a fixation cross and four boxes for stimulus presentation. The boxes were arranged horizontally above fixation.

Spatial Frequency and Selective Attention to Spatial Location
Perception, 1987The effect of spatial attention on the detectability of gratings of different spatial frequency was measured using a probe technique. Three experiments are reported in which the detectability of full-field probe gratings was measured while subjects analyzed stimuli presented in either the central or the peripheral visual field.

Spatial Attention for Pedestrian Detection
2019 16th IEEE International Conference on Advanced Video and Signal Based Surveillance (AVSS), 2019Achieving high detection accuracy and high inference speed is important for a pedestrian detection system in self-driving applications. There exists a trade-off between detection accuracy and inference speed in modern convolu-tional object detectors. In this paper, we propose a novel pedestrian detection system, which leverages spatial attention and a ...

Caffeine and visuo-spatial attention
Psychopharmacology, 1998The effects of two doses of caffeine (1.5 and 3 mg/kg) on various aspects of visual selective attention were investigated in 24 healthy human subjects. Specific task conditions were compared to provide measures of selectivity for a location in the visual field, of distractibility, of selectivity among response alternatives, and of strategic influences.

A Mixture Distribution of Spatial Attention
Experimental Psychology, 2013Although it may seem paradoxical, the unified-focus and multiple-foci theories of spatial selective attention are both well supported by experimental evidence. However, the apparent contradiction is illusory and the two competing views may be reconciled by a closer examination of the spatial mechanisms involved.

The role of spatial attention during spatial encoding
Cognitive Neuroscience, 2013In the present fMRI study, we aimed to assess whether spatial encoding is mediated by spatial attention. During encoding, participants were presented with abstract shapes to the left or right of fixation. During retrieval, old and new shapes were presented at fixation and participants classified each shape as "old-left", "old-right", or "new ...

On the spatial distribution of visual attention.
Journal of Experimental Psychology: Human Perception and Performance, 1986An implication of the data analysis and presentation of Podgorny and Shepard (1983) is that subjects are able to attend simultaneously to more than one square of a grid display when the squares are separated by unattended areas: Attention to such nonunitary areas produces similar benefits as attention to unitary areas.

Attenuation of spatial attentional asymmetries with poor sustained attention
NeuroReport, 2004The co-existence of deficits in sustained and spatial attention in patients with acquired damage to the right cerebral hemisphere has led to the proposition that sustained attention could be a marker for left spatial inattention, or neglect. We investigated the possibility that reductions in leftward spatial attentional asymmetries could arise from ...

Orienting of attention and spatial cognition
Cognitive ProcessingHumans orient to their sensory world through foveation of target location or through covert shifts of attention. Orienting provides primacy to the selected location and in humans improves the precision of discrimination. Covert orienting appears to arise separately from the mechanisms involved in saccadic eye movements.
