Document Summary
The act or state of attending especially through applying the mind to a object of sense or thought. A condition of readiness for such attention involving especially a selective narrowing or focusing of consciousness and receptivity. Attention: the ability to focus on a task, the ability to concentrate, a reference to the allocation of processing resources. We only attend to a subset of stimuli: noises around us, feel of our clothes, pressure on our seats. Dichotic listening task: two messages, delivered simultaneously to both ears, participant is instructed to shadow one messa. Dichotic listening results: most participants shadowed the attended speech successfully, unattended speech. Could tell if male or female voice: one study, reported something strange about unattended speech. Speech had been played backwards: another study, couldn"t repeat any words from a short list repeated. Early-selection theories: information bottleneck occurs early in the stream. Late-selection theories: processing bottleneck occurs late in the stream.
