Probing the Mechanisms of Attention
2009ABSTR/TCT This chapter emphasizes the manlr methods currently being employed to study brain networks related to attcntion. We seek to sct current studies into a historical background of efforts to understand how the brain selects among stimuli and resolves competing responses.

A brain mechanism for attention
Medical Hypotheses, 1990Attention is directed or focussed consciousness. Consciousness is a subjective sensation produced by the simultaneous activation of discrete neurophysiological systems. These are the alerting, awareness, affect, arousal, and attention systems. The process begins with the subcortical scanning of sensory stimuli for affect and significance via pleasure ...

Soviet Psychology, 1969
There have been several attempts in the field of psychology to explain attention mechanisms on the basis of negative inductive relationships. Such an interpretation has certain justifications vis-a-vis the lower forms of attention, usually characterized as involuntary.

Attentive mechanisms in visual search
Spatial Vision, 2004Selective attention can be employed to a restricted region in space or to specific objects. Many properties of this attentional window or spotlight are not well understood. In the present study, we examined the question whether the putative shape of the attentional spotlight can be determined by endogenous cueing within a visual search paradigm ...

Visual attention and the mechanism of metacontrast
Psychological Research, 2006The U-shaped metacontrast function may result from the superimposition of two monotonic components which reflect the effects of mechanisms similar to the peripheral and central processes suggested for backward pattern masking by Turvey (Psychol Rev 80:1-52, 1973).

Attentional Mechanisms in Ventral Pathway
2009Attentional modulation along the ventral pathway of the cortical visual system of primates consists in enhanced representation of the retinal input at a specific location in space, or of objects located anywhere in the visual field which possess a critical feature.

Mechanisms of attention: A developmental study
Journal of Experimental Child Psychology, 1989A model of selective attention is proposed which contains a number of properties. First, stimuli which are irrelevant to the subjects' task can be analyzed to semantic levels automatically, and such stimuli can produce intrusion/interference effects.

Mechanisms of top-down attention
Trends in Neurosciences, 2011Attention exhibits characteristic neural signatures in brain regions that process sensory signals. An important area of future research is to understand the nature of top-down signals that facilitate attentional guidance towards behaviorally relevant locations and features.

2004
This chapter reviews some of the studies demonstrating that attention is associated with an increase in activity in the brain region concerned with the processing of whatever it is that is being attended to. The basic assumption is that there is competition between stimuli for processing by the nervous system.

Neural mechanisms of social attention
Trends in Cognitive Sciences, 2009Social attention is conveyed primarily by gaze, but also by head and body orientation. These cues not only signal a seen agent's direction of attention but are also used to infer their current goals and intentions. Here, we review recent research showing that different gaze, head and body orientations are represented by distinct neural mechanisms, and ...
