However, it is unclear whether exposure to speech sounds during nocturnal sleep facilitates learning of speech sound discrimination. In the present study participants were exposed to non-native speech sounds including tonal changes for the duration of 2 hours per night, for 4 consecutive nights, during sleep stage 2. Stimuli consisted of one standard and two deviant variations of Chinese vowel /a/, which were presented in odd-ball design, in semi-random order. One type of lexical tone (rising tone) was frequently presented, while two other sounds, differing in lexical tone, replaced it infrequently (10%) and randomly. Before and after the exposure, participants\u2019 ability to discriminate between those sounds was tested by giving them an attentive behavioural task in which they were instructed to detect changes in sounds and press a button when hearing a deviant sound. During the pre- and post-measurement, event-related potentials (ERPs) were recorded using a 128-channel sensor net, and an ERP response called mismatch negativity (MMN) was used as indicator of ability to discriminate between the speech sounds. Control group proved a baseline measurement and was not exposed to stimuli during sleep in between the measurements. We found no learning effect specific to exposure group in MMN amplitude. However, a frontocentral MMN response was found, peaking at 235 \u2013 285 ms indicating the participants\u2019 ability to discriminate between non-native speech sounds. The results indicate that Finnish participants are able to discriminate tonal changes in speech sounds in neural level, but it remains unclear whether exposure during sleep can promote auditory perceptual learning.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted using Plone Publishing form by Miia Hakanen (mihakane) on 2016-02-16 12:13:22.164371.
