“…In contrast, when test tokens were presented to the contralateral ear, the adaptation remained stable for 25 min, but at longer delays the small residual effects were not significantly different from zero. These graphs illustrate the quite different duration of adaptation found in the current study than that found by Sharf and Ohde (1981) effects here…”

“…Given the above, and in contrast with Sharf and Ohde (1981), the present research therefore distinguished between testing in the ear that received the adaptor versus the ear that did not. This allowed us to map out, on three different time scales (i.e., hours, minutes seconds), the time course and recovery time for phonetic adaptation, separately for central and peripheral levels.…”

“…However, the literature also makes it clear that the size of the initial adaptation shift is very much dependent on the details of the stimuli, and to some extent, on the details of the test procedure. Our stimuli were chosen to yield very strong adaptation and to be very sensitive to the ear manipulation (which was not included in the Sharf & Ohde (1981) paper).…”

“…It is already clear that even the two variants of phonemic recalibration do not decay at the same rate: whereas audiovisual recalibration is gone after a few tens of seconds (Vroomen et al, 2004), lexically-driven recalibration persists a matter of hours, if not a few days (Eisner & McQueen, 2006;Zhang & Samuel, 2014). Surprisingly, while the question of persistence seems central to elucidating the mechanisms behind phonemic adaptation, Sharf and Ohde (1981) appears to be the only paper in the large literature on speech adaptation to have assessed the recovery time (i.e., how long it takes categorization to return its preadaptation boundary). Using the /pa/ endpoint of a /ba/-/pa/ continuum as the adaptor, Sharf and Ohde measured how much of the initial adaptation shift was left after 1, 4, 7 and 28 min; this was done within-participant, but counterbalancing the interval condition.…”

“…Therefore, the first aim of our study was to assess the recovery time after adaptation using adaptors and test stimuli that have been shown to produce extremely large initial adaptation shifts. Sharf and Ohde (1981) used binaural presentation. In contrast, we use monaural presentation of the adaptor and test stimuli because previous studies using this procedure have provided evidence for more than one level of speech analysis.…”

Over the course of a lifetime, adults develop perceptual categories for the vowels and consonants in their native language, based on the distribution of those sounds in their environment. However, in any given listening situation, the short-term distribution of sounds can cause changes in this long-term categorization. For example, if the same sound (the "adaptor") is heard many times in a short period of time, listeners adapt and become less prone to hearing that sound. Although hundreds of speech selective adaptation experiments have been published, there is almost no information about how long this adaptation lasts.Using stimuli chosen to produce very large initial adaptation, we test adaptation effects with essentially no delay, and with delays of 25 min, 90 min, and 5.5 hr; these tests probe the duration of adaptation both in the (single) ear to which the adaptor was presented, and in the opposite ear. Reliable adaptation remains 5.5 hours after exposure in the same-ear condition, whereas it is undetectable at 90 min in the opposite ear. Surprisingly, the amount of residual adaptation is largely unaffected by whether the listener is exposed to speech between adaptation and test, unless the speech shares critical acoustic properties with the adapting sounds. Analyses of the shifts on three time scales (seconds, minutes, and hours) provide information about the multiple levels of analysis that the speech signal undergoes. Public Significance Statement: Spoken language is the primary mode of communication for most humans. The current work helps to specify the ways in which the speech signal is decoded, helping us to understand how humans accomplish this challenging task.
