“…Schmidt (2018) found in a crosssectional L2 perception study of aspirated-/s/ that the American English learners of Spanish did not acquire the perceptual mapping or association of syllable-final aspirated [h] forms to Spanish /s/ until late levels of proficiency (third-year university Spanish courses or above), if at all-and frequently "ignored" syllable-final [h] or perceived it as Spanish "f." Indeed, though all students in the current study reported awareness of the local dialectal pronunciation of "y" and "ll," only one-third reported awareness of the local pronunciation of syllable-final "s." It is argued, thus, that a major contributor to why the learners in the current study did not produce the local /s/-lenited variants [h ϕ] by the end of the shortterm study abroad period-and why Geeslin and Gudmestad (2011) also found low levels of use-is the low phonetic saliency, or acoustic prominence, of these phones for English speakers (due potentially to the position of the aspirated cue at the end of a syllable or a word, a less salient position (Cutler, 1982), and to its likely association with the previous vowel for English speakers and is as such "ignored" as a consonant segment (see L. B. Schmidt, 2018)). Thus, this low phonetic saliency results in a lack of noticing or awareness of the lenited-/s/ forms by the L2 learners-which, of course, is argued to be a critical condition for learning to occur (see the Noticing Hypothesis; R. Schmidt, 1990).…”
