Subject: Re: [AUDITORY] Serial dependence in auditory perception From: Matthew Winn <0000011b522b2e6a-dmarc-request@xxxxxxxx> Date: Wed, 26 Jan 2022 00:02:59 -0600--0000000000009fa4f805d675f536 Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: quoted-printable You=E2=80=99ll find a lot of studies that explore this type of phenomenon u= nder the general label =E2=80=9Cauditory context effects=E2=80=9D, =E2=80=9Cspectral= contrast effects=E2=80=9D or =E2=80=9Cauditory enhancement effects=E2=80=9D. Christian Stilp has written= a review of how these effects emerge in the perception of speech sounds, and his paper is available here: https://louisville.edu/psychology/stilp/lab/publication-pdf/stilp-2019-wire= s-1 the abstract: *The extreme acoustic variability of speech is well established, which makes the proficiency of human speech perception all the more impressive. Speech perception, like perception in any modality, is relative to context, and this provides a means to normalize the acoustic variability in the speech signal. Acoustic context effects in speech perception have been widely documented, but a clear understanding of how these effects relate to each other across stimuli, timescales, and acoustic domains is lacking. Here we review the influences that spectral context, temporal context, and spectrotemporal context have on speech perception. Studies are organized in terms of whether the context precedes the target (forward effects) or follows it (backward effects), and whether the context is adjacent to the target (proximal) or temporally removed from it (distal). Special cases where proximal and distal contexts have competing influences on perception are also considered. Across studies, a common theme emerges: acoustic differences between contexts and targets are perceptually magnified, producing contrast effects that facilitate perception of target sounds and words. This indicates enhanced sensitivity to changes in the acoustic environment, which maximizes the amount of potential information that can be transmitted to the perceiver.* Many other studies exist under this heading as well, including some in listeners with hearing impairment/cochlear implants by Feng, Oxenham and others.
