Changes in otoacoustic emissions during selective auditory and visual attention.

Selective attention reduces physiological noise in the external ear canals of humans. II: visual attention.

Human subjects performed in several behavioral conditions requiring, or not requiring, selective attention to visual stimuli. Specifically, the attentional task was to recognize strings of digits that had been presented visually. A nonlinear version of the stimulus-frequency otoacoustic emission (SFOAE), called the nSFOAE, was collected during the visual presentation of the digits. The segment ...

Automatic Detection of Selective Auditory Attention Via Transient Evoked Otoacoustic Emissions

Attentional modulation of the inner ear: a combined otoacoustic emission and EEG study.

Attending to a single stimulus in a complex multisensory environment requires the ability to select relevant information while ignoring distracting input. The underlying mechanism and involved neuronal levels of this attentional gain control are still a matter of debate. Here, we investigated the influence of intermodal attention on different levels of auditory processing in humans. It is known...

Neurophysiological mechanisms of auditory selective attention in humans.

This chapter reviews the main data on the physiological substrates of auditory selective attention and their contribution to theoretical models of cognitive psychology. While event-related potentials, magnetoencephalography, and more recently neuroimaging techniques have provided fundamental information on the neural correlates of attention in the central cortical system, measurements of the fr...

Attention effects on distortion-product otoacoustic emissions with contralateral speech stimuli.

This study investigated the effect of selective attention on the distortion-product otoacoustic emission (DPOAE) level through the use of environmentally meaningful, contralateral auditory stimuli. Four different conditions were used for measurement: quiet, contralateral noise, contralateral speech (unattended), and contralateral speech (attended). A statistically significant suppression effect...
