“…Moreover, a recent study (Skoe, Burakiewicz, Figueiredo, & Hardin, 2017) suggests that in the human brain the organization of basic sound processing, which refers to the auditory neuroaxis (ability to process sounds that are not speech-specific, such as the fundamental frequency), is influenced by bilingual experience. The latter demonstration is of particular interest because there is also evidence that orally mimicked tool sounds (and animal vocalizations) in monolingual contexts (and/ or even monolingual individuals) engage left hemisphere structures (Lewis, Silberman, Donai, Frum, & Brefczynski-Lewis, 2018).…”

health psychology report • volume 8(1),  original article background The impact of bilingualism on lateralized brain functions such as praxis -the control of skilled actions -and language representations themselves, particularly in the auditory domain, is still largely unknown. Recent studies suggest that bilingualism affects both basic (fundamental frequency) sound and action-related speech processing. Whether it can impact non-verbal action sound processing is a question of debate. participants and procedureHere we examined twenty bilinguals using a dichotic listening paradigm, in which in addition to repeating the just heard action words, participants named -in Polish or English -one of two simultaneously presented tool sounds from attended ears. The results were compared with data from these same participants tested with reading the same words in a visual-half field paradigm. resultsIn contrast to typical outcomes from monolinguals, the laterality indices of action-related sound processing (verbal and non-verbal) were not left lateralized but hemispherically balanced. Notably, despite similar organization of tool-and action-word sound processing, their auditory (balanced) and visual-language (left-lateralized) representations might be independent because there were no significant correlations between any of their laterality indices. conclusionsThis indicates that bilingualism might involve reshuffling/ reorganization of typically lateralized brain functions and such plasticity will have consequences for second language learning strategies, as well as for neurorehabilitation.

Purpose From an anthropological perspective of hominin communication, the human auditory system likely evolved to enable special sensitivity to sounds produced by the vocal tracts of human conspecifics whether attended or passively heard. While numerous electrophysiological studies have used stereotypical human-produced verbal (speech voice and singing voice) and nonverbal vocalizations to identify human voice–sensitive responses, controversy remains as to when (and where) processing of acoustic signal attributes characteristic of “human voiceness” per se initiate in the brain. Method To explore this, we used animal vocalizations and human-mimicked versions of those calls (“mimic voice”) to examine late auditory evoked potential responses in humans. Results Here, we revealed an N1b component (96–120 ms poststimulus) during a nonattending listening condition showing significantly greater magnitude in response to mimics, beginning as early as primary auditory cortices, preceding the time window reported in previous studies that revealed species-specific vocalization processing initiating in the range of 147–219 ms. During a sound discrimination task, a P600 (500–700 ms poststimulus) component showed specificity for accurate discrimination of human mimic voice. Distinct acoustic signal attributes and features of the stimuli were used in a classifier model, which could distinguish most human from animal voice comparably to behavioral data—though none of these single features could adequately distinguish human voiceness. Conclusions These results provide novel ideas for algorithms used in neuromimetic hearing aids, as well as direct electrophysiological support for a neurocognitive model of natural sound processing that informs both neurodevelopmental and anthropological models regarding the establishment of auditory communication systems in humans.
