Hemispheric Asymmetries in Speech Perception: Sense, Nonsense and Modulations

Background: The well-established left hemisphere specialisation for language processing has long been claimed to be based on a low-level auditory specialization for specific acoustic features in speech, particularly regarding 'rapid temporal processing'.Methodology: A novel analysis/synthesis technique was used to construct a variety of sounds based on simple sentences which could be manipulated in spectro-temporal complexity, and whether they were intelligible or not. All sounds consisted of two noise-excited spectral prominences (based on the lower two formants in the original speech) which could be static or varying in frequency and/or amplitude independently. Dynamically varying both acoustic features based on the same sentence led to intelligible speech but when either or both acoustic features were static, the stimuli were not intelligible. Using the frequency dynamics from one sentence with the amplitude dynamics of another led to unintelligible sounds of comparable spectro-temporal complexity to the intelligible ones. Positron emission tomography (PET) was used to compare which brain regions were active when participants listened to the different sounds.Conclusions: Neural activity to spectral and amplitude modulations sufficient to support speech intelligibility (without actually being intelligible) was seen bilaterally, with a right temporal lobe dominance. A left dominant response was seen only to intelligible sounds. It thus appears that the left hemisphere specialisation for speech is based on the linguistic properties of utterances, not on particular acoustic features

СУЧАСНІ АСПЕКТИ МЕДИКО-СОЦІАЛЬНОЇ РЕАБІЛІТАЦІЇ ІНВАЛІДІВ - УЧАСНИКІВ АНТИТЕРОРИСТИЧНОЇ ОПЕРАЦІЇ

Purpose: to search the needs of ATO participants in medical and social rehabilitation measures at the main disabling pathology.Materials and Methods. The needs of ATO participants in medical and social rehabilitation measures are calculated on the basis of analysis of 3947 individual rehabilitation programs (IRP) developed by rehabilitation specialists of medical and social expert commissions in 19 regions of Ukraine with the main disabling pathology (after the consequences of trauma and somatic pathology). Methods: expert evaluations, statistical-mathematical, meta-analysis according to the data of medical and expert documentation and IPR, analytical and logical.Results. The obtained data testify to the availability of complex diverse needs of disabled patients-participants ATO in medical and social rehabilitation activities (medical, psychological, professional, social, technical means of rehabilitation, medical devices) the volume of which varies depending on the type of services, age, severity of disability, pathology.Conclusion. When forming individual programs of rehabilitation doctors of medical and social expert commission underestimate the role of services in professional, social, technical means of rehabilitation in removing limitation of life, improving the quality of life of the disabled, their social adaptation. This needs to be improved by the work of the medical and social expert commissions.Мета роботи – визначення потреб інвалідів-учасників АТО в заходах медико-соціальної реабілітації при основній інвалідизуючій патології.Матеріали та методи. Розрахована потреба інвалідів-учасників АТО в заходах медико-соціальної реабілітації на підставі аналізу 3947 індивідуальних програм реабілітації (ІПР), які розроблені реабілітологами медико-соціальних експертних комісій (МСЕК) 19 областей України при основній інвалідизуючій патології (наслідках бойових травм та соматичної патології). Використані методи: експертних оцінок, статистично-математичний, мета-аналіз за даними медико-експертної документації та ІПР, аналітико-логічний.Результати дослідження. Отримані дані свідчать про наявність комплексних різноманітних потреб інвалідів-учасників АТО в заходах медико-соціальної реабілітації (медичної, психологічної, професійно-трудової, соціальної, технічних засобах реабілітації та виробах медичного призначення), обсяг яких відрізняється в залежності від виду послуг, віку, важкості інвалідності, патології.Висновки. При формуванні ІПР має місце недооцінка ролі послуг з професійної, соціальної реабілітації, технічних засобів реабілітації в усуненні обмежень життєдіяльності, покращенні якості життя інвалідів, їх соціальної адаптації, що потребує удосконалення роботи МСЕК

What drives sound symbolism? Different acoustic cues underlie sound-size and sound-shape mappings

Sound symbolism refers to the non-arbitrary mappings that exist between phonetic properties of speech sounds and their meaning. Despite there being an extensive literature on the topic, the acoustic features and psychological mechanisms that give rise to sound symbolism are not, as yet, altogether clear. The present study was designed to investigate whether different sets of acoustic cues predict size and shape symbolism, respectively. In two experiments, participants judged whether a given consonant-vowel speech sound was large or small, round or angular, using a size or shape scale. Visual size judgments were predicted by vowel formant F1 in combination with F2, and by vowel duration. Visual shape judgments were, however, predicted by formants F2 and F3. Size and shape symbolism were thus not induced by a common mechanism, but rather were distinctly affected by acoustic properties of speech sounds. These findings portray sound symbolism as a process that is not based merely on broad categorical contrasts, such as round/unround and front/back vowels. Rather, individuals seem to base their sound-symbolic judgments on specific sets of acoustic cues, extracted from speech sounds, which vary across judgment dimensions
