“…7 11 19 The MMN response can be determined by the attention to the stimulus rather than its frequency and intensity. For this reason, the best results can be achieved when the subject ignores the auditory stimuli presented, directing her attention to more interesting stimuli, that is, watching a video, viewing a book, playing a game in the computer or tablet, among others.…”

Introduction Mismatch Negativity (MMN) corresponds to a response of the central auditory nervous system. Objective The objective of this study is to analyze MMN latencies and amplitudes in normal-hearing adults and compare the results between ears, gender and hand dominance. Methods This is a cross-sectional study. Forty subjects participated, 20 women and 20 men, aged 18 to 29 years and having normal auditory thresholds. A frequency of 1000Hz (standard stimuli) and 2000Hz (deviant stimuli) was used to evoked the MMN. Results Mean latencies in the right ear were 169.4ms and 175.3ms in the left ear, with mean amplitudes of 4.6µV in the right ear and 4.2µV in the left ear. There was no statistically significant difference between ears. The comparison of latencies between genders showed a statistically significant difference for the right ear, being higher in the men than in women. There was no significant statistical difference between ears for both right-handed and left-handed group. However, the results indicated that the latency of the right ear was significantly higher for the left handers than the right handers. We also found a significant result for the latency of the left ear, which was higher for the right handers. Conclusion It was possible to obtain references of values for the MMN. There are no differences in the MMN latencies and amplitudes between the ears. Regarding gender, the male group presented higher latencies in relation to the female group in the right ear. Some results indicate that there is a significant statistical difference of the MMN between right- and left-handed individuals.

“…The same authors (Zora, Schwarz, & Heldner, 2015) investigated also the contribution of two specific features, f0 and intensity to stress processing in English. In the study, participants heard stress minimal pairs versions (i.e., the same word with trochaic and iambic stress pattern) of the word ‘upset’ and the pseudoword ‘ukfet’.…”

Word stress representations are language-specific: evidence from event-related brain potentials

Understanding speech at the basic levels entails the simultaneous and independent processing of phonemic and prosodic features. While it is well-established that phoneme perception relies on language-specific long-term traces, it is unclear if the processing of prosodic features similarly involves language-specific representations. In the present study, we investigated the processing of a specific prosodic feature, word stress, using the method of event-related brain potentials (ERPs) employing a cross-linguistic approach. Hungarian participants heard disyllabic pseudowords stressed either on the first (legal stress) or on the second (illegal stress) syllable, pronounced either by a Hungarian or a German speaker. Results obtained using a data-driven ERP analysis methodology showed that all pseudowords in the deviant position elicited an Early Differentiating Negativity (EDN) and a Mismatch Negativity (MMN) component, except for the Hungarian pseudowords stressed on the first syllable. This suggests that Hungarian listeners did not process the native legal stress pattern as deviant, but the same stress pattern with a non-native accent was processed as deviant. This implies that the processing of word stress was based on language-specific long-term memory traces.

“…Given that tone has been shown to be a part of the lexical specification of morphemes in Swedish with an electrophysiological approach and that lexical specification of prosodic features has been shown to be the case in various languages (Zora et al, 2015, 2016), the present study investigates whether stress is also a lexical property of morphemes in Swedish. The aim is to establish how lexically and phonologically stressed words are represented in the brain by using the mismatch negativity (MMN) component of event-related potentials (ERPs).…”

“…MMN signals the brain's automatic reaction to any change in the auditory sensory input and is elicited irrespective of the subject's attention to the auditory stimulus (Näätänen et al, 1978, 2007; Näätänen and Winkler, 1999). In addition, MMN reflects the activation of long-term memory traces for lexical information (Dehaene-Lambertz, 1997; Pulvermüller et al, 2001; Shtyrov and Pulvermüller, 2002; Zora et al, 2015, 2016). Shtyrov and Pulvermüller (2002), for instance, investigated MMN responses elicited either by words presented among words or pseudowords or by pseudowords presented among words.…”

“…Therefore, in theory, presentation of a word that does not occur in the usual language output (either as a stem or a derivation) would not initiate the activation process. Memory traces for prosodic information and their contribution toward the lexical activation process have previously been investigated in English (Zora et al, 2015) and Turkish (Zora et al, 2016). The findings indicated that the memory traces for words are indeed activated on the sole basis of prosodic information, and the presence of prosodic representations in lexical representations has a differential effect on the processing of prosodic changes.…”

Lexical Specification of Prosodic Information in Swedish: Evidence from Mismatch Negativity

Like that of many other Germanic languages, the stress system of Swedish has mainly undergone phonological analysis. Recently, however, researchers have begun to recognize the central role of morphology in these systems. Similar to the lexical specification of tonal accent, the Swedish stress system is claimed to be morphologically determined and morphemes are thus categorized as prosodically specified and prosodically unspecified. Prosodically specified morphemes bear stress information as part of their lexical representations and are classified as tonic (i.e., lexically stressed), pretonic and posttonic, whereas prosodically unspecified morphemes receive stress through a phonological rule that is right-edge oriented, but is sensitive to prosodic specification at that edge. The presence of prosodic specification is inferred from vowel quality and vowel quantity; if stress moves elsewhere, vowel quality and quantity change radically in phonologically stressed morphemes, whereas traces of stress remain in lexically stressed morphemes. The present study is the first to investigate whether stress is a lexical property of Swedish morphemes by comparing mismatch negativity (MMN) responses to vowel quality and quantity changes in phonologically stressed and lexically stressed words. In a passive oddball paradigm, 15 native speakers of Swedish were presented with standards and deviants, which differed from the standards in formant frequency and duration. Given that vowel quality and quantity changes are associated with morphological derivations only in phonologically stressed words, MMN responses are expected to be greater in phonologically stressed words than in lexically stressed words that lack such an association. The results indicated that the processing differences between phonologically and lexically stressed words were reflected in the amplitude and topography of MMN responses. Confirming the expectation, MMN amplitude was greater for the phonologically stressed word than for the lexically stressed word and showed a more widespread topographic distribution. The brain did not only detect vowel quality and quantity changes but also used them to activate memory traces associated with derivations. The present study therefore implies that morphology is directly involved in the Swedish stress system and that changes in phonological shape due to stress shift cue upcoming stress and potential addition of a morpheme.
