Spatial attention freezes during the attention blink
Psychophysiology, 2006AbstractA variant of the rapid serial visual presentation paradigm was used to display sequentially two lateral sequences of stimuli, one to the left and one to the right of fixation, embedding two pairs of target stimuli, T1 and T2. T1 was composed of a pair of alphanumeric characters, and subjects had either to ignore T1 or to encode T1 for a delayed

Attentional set and the gradient of visual spatial attention
Neuroscience Letters, 2019There are a number of factors that may influence the shape and scope of the gradient of visual attention. This study examined the role of attentional set in determining the scope and presence of suppression in the gradient of visual selective attention observed in the P1 event related potential waveform.

The spatial distribution of attention
Current Opinion in Psychology, 2019Understanding how spatial attention is distributed over space (i.e. the attentional window) is highly important for theoretical, methodological, as well as applied reasons. One fundamental challenge to the study of the attentional window is that most of our current knowledge is based on measuring distractors interference, or relying in some other way ...

Spatial attention systems in spatial neglect
Neuropsychologia, 2015It has been established that processes relating to 'spatial attention' are implemented at cortical level by goal-directed (top-down) and stimulus-driven (bottom-up) networks. Spatial neglect in brain-damaged individuals has been interpreted as a distinguished exemplar for a disturbance of these processes.

Hemispheric control of spatial attention
Brain and Cognition, 1990According to the activation-orienting hypothesis the distribution of attention in space is biased in the direction contralateral to the more activated hemisphere. The present investigation tested this proposal and evaluated the nature of hemispheric differences in orienting control. Activation imbalance was produced by a unilateral visual stimulus. The

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 ...

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.
