“…Furthermore, in their recent study, Mueller, Friederici, and Mannel (2012) divide infants by the polarity of their mismatch response and as a result of matching the electrophysiological responses to behavioral results, argue that the positive MMR is a correlate of immature stimulus comparison. In an early study Näätänen, Simpson, and Loveless (1982) called the slightly differing deviants as 'proximates.' They got a more prolonged MMN to this kind of stimuli, which they attributed to subjective uncertainty.…”

Infants born prematurely are at higher risk for later linguistic deficits present in delayed or atypical processing of phonetic and prosodic information. In order to be able to specify the nature of this atypical development, it is important to investigate the role of early experience in language perception. According to the concept of Gonzalez-Gomez and Nazzi (2012) there is a special intrauterine sensitivity to the prosodic features of languages that should have a special role in language acquisition. Therefore, we may also assume that pre-and full-term infants having months difference in intrauterine experience show different maturation patterns of processing prosodic and phonetic information present at word level. The aim of our study was to investigate the effect of these differences on word stress pattern vs. phoneme information processing. Two age groups of infants (6 and 10 month-olds) were included in our study. 21 of 46 of the total of infants investigated were prematurely born with low birth weight. We used the mismatch negativity (MMN) event related brain potential (ERP) component, a widely used electrophysiological correlate of acoustic change detection, for testing the assumed developmental changes of phoneme and word stress discrimination. In a passive oddball paradigm we used a word as standard, a pseudoword as phoneme deviant, and an illegally uttered word as stress deviant. Our results showed no differences in MMN responses in the phoneme deviant condition between the groups, meaning a relatively intact maturation of phoneme processing of preterm infants as compared to their contemporaries. However, the mismatch responses measured in the stress condition revealed significant betweengroup differences. These results strengthen the view that the total length of intrauterine experience influences the time of emergence of prosodic processing.

“…MMN is a frontocentral negative component, usually peaking at 100-250 ms from the deviation in the stimuli, which is elicited when a novel stimulus interrupts the repeated presentation of the same stimulus. This component is sensitive to changes not only in the acoustic characteristics of auditory stimuli (Näätänen, Simpson, & Loveless, 1982), but also to their phonological properties (for a review, Pulvermüller & Shtyrov, 2006). For example, Näätänen and collaborators (Näätänen et al, 1997) demonstrated MMN responses to phoneme changes when Finnish listeners heard the Finnish vowel /ö/ or the unknown Estonian vowel /õ/ in a list composed predominantly of the Finnish vowel /e/.…”

Behavioral and electrophysiological evidence for the impact of regional variation on phoneme perception

a b s t r a c tThis event-related potential (ERP) study examined the impact of phonological variation resulting from a vowel merger on phoneme perception. The perception of the /e/-/e/ contrast which does not exist in Southern French-speaking regions, and which is in the process of merging in Northern French-speaking regions, was compared to the /ø/-/y/ contrast, which is stable in all French-speaking regions. French-speaking participants from Switzerland for whom the /e/-/e/ contrast is preserved, but who are exposed to different regional variants, had to perform a same-different task. They first heard four phonemically identical but acoustically different syllables (e.g., /be/-/be/-/be/-/be/), and then heard the test syllable which was either phonemically identical to (/be/) or phonemically different from (/be/) the preceding context stimuli. The results showed that the unstable /e/-/e/ contrast only induced a mismatch negativity (MMN), whereas the /ø/-/y/ contrast elicited both a MMN and electrophysiological differences on the P200. These findings were in line with the behavioral results in which responses were slower and more error-prone in the /e/-/e/ deviant condition than in the /ø/-/y/ deviant condition. Together these findings suggest that the regional variability in the speech input to which listeners are exposed affects the perception of speech sounds in their own accent.

“…This pre-attentive process compares an incoming stimulus with stimuli stored in the auditory sensory memory. It automatically sends an interrupt to the central processing channel whenever an auditory stimulus is either not represented in the auditory memory system or has a label "significant" (in the case the individual has to react on the stimulus) (Öhman 1979;Näätänen 1979). In schizophrenic patients, MMN is reduced as compared to healthy controls (Oades et al 1997;Javitt et al 1993Javitt et al , 1995Shelley et al 1991).…”
