The implication is that the cognitive and perceptual demands of a task can affect the first neural stage of auditory processing\u2014the sensory receptors themselves. However, the directions of the reported attentional effects have been inconsistent, the magnitudes of the observed differences typically have been small, and comparisons across studies have been made difficult by significant procedural differences. In this study, a nonlinear version of the stimulus-frequency OAE (SFOAE), called the nSFOAE, was used to measure cochlear responses from human subjects while they simultaneously performed behavioral tasks requiring selective auditory attention (dichotic or diotic listening), selective visual attention, or relative inattention. Within subjects, the differences in nSFOAE magnitude between inattention and attention conditions were about 2\u20133\u2009dB for both auditory and visual modalities, and the effect sizes for the differences typically were large for both nSFOAE magnitude and phase. These results reveal that the cochlear efferent reflex is differentially active during selective attention and inattention, for both auditory and visual tasks, although they do not reveal how attention is improved when efferent activity is greater.<\/jats:p>","DOI":"10.1121\/1.4919350","type":"journal-article","created":{"date-parts":[[2015,5,20]],"date-time":"2015-05-20T00:30:20Z","timestamp":1432081820000},"page":"2737-2757","update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":38,"title":["Changes in otoacoustic emissions during selective auditory and visual attention"],"prefix":"10.1121","volume":"137","author":[{"given":"Kyle P.","family":"Walsh","sequence":"first","affiliation":[{"name":"University of Texas Department of Psychology and Center for Perceptual Systems, , 1 University Station A8000, Austin, Texas 78712-0187, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Edward G.","family":"Pasanen","sequence":"additional","affiliation":[{"name":"University of Texas Department of Psychology and Center for Perceptual Systems, , 1 University Station A8000, Austin, Texas 78712-0187, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dennis","family":"McFadden","sequence":"additional","affiliation":[{"name":"University of Texas Department of Psychology and Center for Perceptual Systems, , 1 University Station A8000, Austin, Texas 78712-0187, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"231","reference":[{"key":"2023080101195276800_c1","doi-asserted-by":"publisher","first-page":"2889","DOI":"10.1121\/1.2169918","article-title":"Time-course of the human medial olivocochlear reflex","volume":"119","year":"2006","journal-title":"J.
