Mechanisms of attention in touch

Somatosensory & Motor Research, 1999
A series of experiments demonstrated the role of higher level cognitive processes, such as attention, in tactile perception. The first series of experiments demonstrated that automatic orienting to a tactile stimulus resulted in inhibition of subsequent stimuli at that body site--inhibition of return (IOR).

On a spectral attentional mechanism

Proceedings CVPR IEEE Computer Society Conference on Computer Vision and Pattern Recognition, 1996
This paper describes an attentional mechanism based on the interpretation of spectral signatures for detecting regular object configurations in areas of an image delineated using context information. The proposed global operator relies on the spectral analyse's of edge structure and exploits spatial as well as frequency domain constraints derived from ...

Probing the Mechanisms of Attention

2009
ABSTR/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, 1990
Attention 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 ...

Attentive mechanisms in visual search

Spatial Vision, 2004
Selective 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 ...

Mechanisms of attention: A developmental study

Journal of Experimental Child Psychology, 1989
A 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.
