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.

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.

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.

Historically, most psychoacoustic studies measured performance on tasks limited by bottom-up, sensory factors. However, in the everyday world, sensory sensitivity does not always determine performance. The problem in many everyday settings is not that components of an important sound source cannot be heard, but rather that they are not noticed amidst ...

CBAM: Convolutional Block Attention Module
European Conference on Computer Vision, 2018We propose Convolutional Block Attention Module (CBAM), a simple yet effective attention module for feed-forward convolutional neural networks. Given an intermediate feature map, our module sequentially infers attention maps along two separate dimensions,

This review focuses on how covert attention modulates perception. It explains why attention is considered a selective process, the constructs of covert attention, and spatial endogenous and exogenous attention. This review includes the effects of spatial attention on discriminability and appearance in tasks mediated by contrast sensitivity and spatial ...

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 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.

Episodic memory for spatial context biases spatial attention
Experimental Brain Research, 2008The study explores the bottom-up attentional consequences of episodic memory retrieval. Individuals studied words (Experiment 1) or pictures (Experiment 2) presented on the left or on the right of the screen. They then viewed studied and new stimuli in the centre of the screen.
