“…On the other hand, without the higher spatial resolution in fMRI, we would not have been able to reveal the visual cortex activation to deviant events. Given that the laterality of mismatch responses to auditory stimuli follows a time course [57], [58], we cannot rule out that the right-lateralized pattern in the present study is due to a latency effect. Indeed, for MEG recordings during pitch identification, a faster right-hemispheric response has been found according to the left-ear advantage for pitch processing, but the categorization task was left-hemispheric [43].…”

Hemodynamic mismatch responses can be elicited by deviant stimuli in a sequence of standard stimuli even during cognitive demanding tasks. Emotional context is known to modulate lateralized processing. Right-hemispheric negative emotion processing may bias attention to the right and enhance processing of right-ear stimuli. The present study examined the influence of induced mood on lateralized pre-attentive auditory processing of dichotic stimuli using functional magnetic resonance imaging (fMRI). Faces expressing emotions (sad/happy/neutral) were presented in a blocked design while a dichotic oddball sequence with consonant-vowel (CV) syllables in an event-related design was simultaneously administered. Twenty healthy participants were instructed to feel the emotion perceived on the images and to ignore the syllables. Deviant sounds reliably activated bilateral auditory cortices and confirmed attention effects by modulation of visual activity. Sad mood induction activated visual, limbic and right prefrontal areas. A lateralization effect of emotion-attention interaction was reflected in a stronger response to right-ear deviants in the right auditory cortex during sad mood. This imbalance of resources may be a neurophysiological correlate of laterality in sad mood and depression. Conceivably, the compensatory right-hemispheric enhancement of resources elicits increased ipsilateral processing.

“…Previous research found inconsistent categorical effects for fricatives, which were discriminated categorically in some studies but not in others (Fujisaki & Kawashima, 1968; Healy & Repp, 1982; Mann & Repp, 1980; Repp, 1981). However, these studies mainly focused on behavioral tasks (for an exception, see Lipski, 2006). Here we examine whether fricative perception shows enhanced within-category discrimination, similarly to vowels, or whether it is strongly categorical, similarly to plosive consonants.…”

Categorical effects in fricative perception are reflected in cortical source information

Previous research in speech perception has shown that category information affects the discrimination of consonants to a greater extent than vowels. However, there has been little electrophysiological work on the perception of fricative sounds, which are informative for this contrast as they share properties with both consonants and vowels. In the current study we address the relative contribution of phonological and acoustic information to the perception of sibilant fricatives using event-related fields (ERFs) and dipole modeling with magnetoencephalography (MEG). We show that the field strength of neural responses peaking approximately 200 ms after sound onset co-varies with acoustic factors, while the cortical localization of earlier M100 responses suggests a stronger influence of phonological categories. We propose that neural equivalents of categorical perception for fricative sounds are best seen using localization measures, and that spectral cues are spatially coded in human cortex.

“…In this study, we examine electrophysiological activity of the brain to understand the perception of English dental fricative sounds in two groups of proficient L2 listeners, which has been rarely done. Some previous research (mainly using magnetoencephalography) on fricative perception examined L1 English phonemic contrasts such as /s/ and ∫ ( Miller and Zhang, 2014 ; Lago et al, 2015 ) as well as responses to Polish fricatives by native and inexperienced non-native listeners ( Lipski and Mathiak, 2007 ). It remains unclear whether experience with typical mispronunciations of L2 speech sounds lead to cross-linguistically distinct memory traces for non-native phonemes.…”

The Mismatch Negativity (MMN) response has often been used to measure memory traces for phonological representations and to show effects of long-term native language (L1) experience on neural organization. We know little about whether phonological representations of non-native (L2) phonemes are modulated by experience with distinct non-native accents. We used MMN to examine effects of experience with L2-accented speech on auditory brain responses. Specifically, we tested whether it is long-term experience with language-specific L2 pronunciations or instead acoustic similarity between L2 speech sounds that modulates non-native phoneme perception. We registered MMN responses of Dutch and German proficient L2 speakers of English to the English interdental fricative /𝜃/ and compared it to its non-native pronunciations /s/ (typical pronunciation of /𝜃/ for German speakers) and /t/ (typical pronunciation of /𝜃/ for Dutch speakers). Dutch and German listeners heard the English pseudoword thond and its pronunciation deviants sond and tond. We computed the identity Mismatch Negativity (iMMN) by analyzing the difference in ERPs when the deviants were the frequent vs. the infrequent stimulus for the respective group of L2 listeners. For both groups, tond and sond elicited mismatch effects of comparable size. Overall, the results suggest that experience with deviant pronunciations of L2 speech sounds in foreign-accented speech does not alter auditory memory traces. Instead, non-native phoneme perception seems to be modulated by acoustic similarity between speech sounds rather than by experience with typical L2 pronunciation patterns.
