Effect of musical expertise on the perception of duration and pitch in language: A cross-linguistic study.

This study adopts a cross-linguistic perspective and investigates how musical expertise affects the perception of duration and pitch in language. Native speakers of Chinese (N = 44) and Estonian (N = 46), each group subdivided into musicians and non-musicians, participated in a mismatch negativity (MMN) experiment where they passively listened to both Chinese and Estonian stimuli, followed by a behavioral experiment where they attentively discriminated the stimuli in the non-native language (i.e., Chinese to Estonian participants and Estonian to Chinese participants). In both experiments, stimuli of duration change, pitch change, and duration plus pitch change were discriminated. We found higher behavioral sensitivity among Chinese musicians than non-musicians in perceiving the duration change in Estonian and higher behavioral sensitivity among Estonian musicians than non-musicians in perceiving all types of changes in Chinese, but no corresponding effect was found in the MMN results, which suggests a more salient effect of musical expertise on foreign language processing when attention is required. Secondly, Chinese musicians did not outperform non-musicians in attentively discriminating the pitch-related stimuli in Estonian, suggesting that musical expertise can be overridden by tonal language experience when perceiving foreign linguistic pitch, especially when an attentive discrimination task is administered. Thirdly, we found larger MMN among Chinese and Estonian musicians than their non-musician counterparts in perceiving the largest deviant (i.e., duration plus pitch) in their native language. Taken together, our results demonstrate a positive effect of musical expertise on language processing.

Linguistic and affective characteristics of script-driven imagery for adults with posttraumatic stress order: Associations with clinical outcomes during deep transcranial magnetic stimulation.

Brief exposure to traumatic memories using script-driven imagery (SDI) has been proposed as a promising treatment for posttraumatic stress disorder (PTSD). This study investigated the effect of SDI plus active versus sham deep transcranial magnetic stimulation (TMS) in a secondary analysis of a randomized controlled trial for adults with PTSD (N = 134). Linguistic features of scripts and self-reported distress during a 12-session deep TMS treatment protocol were examined as they related to (a) baseline PTSD symptom severity, (b) trauma characteristics, and (c) treatment outcomes. Linguistic Inquiry and Word Count (LIWC) software was used to analyze the following linguistic features of SDIs: negative emotion, authenticity, and cognitive processing. More use of negative emotion words was associated with less severe self-reported and clinician-rated baseline PTSD symptom severity, r = -.18, p = .038. LIWC features did not differ based on index trauma type, range: F(3, 125) = 0.29-0.49, ps = .688-.831. Between-session reductions in self-reported distress across SDI trials predicted PTSD symptom improvement across both conditions at 5-week, B = -15.68, p = .010, and 9-week endpoints, B = -16.38, p = .011. Initial self-reported distress and linguistic features were not associated with treatment outcomes. The findings suggest that individuals with PTSD who experience between-session habituation to SDI-related distress are likely to experience a corresponding improvement in PTSD symptoms.

Complexity of STG signals and linguistic rhythm: a methodological study for EEG data.

The superior temporal and the Heschl's gyri of the human brain play a fundamental role in speech processing. Neurons synchronize their activity to the amplitude envelope of the speech signal to extract acoustic and linguistic features, a process known as neural tracking/entrainment. Electroencephalography has been extensively used in language-related research due to its high temporal resolution and reduced cost, but it does not allow for a precise source localization. Motivated by the lack of a unified methodology for the interpretation of source reconstructed signals, we propose a method based on modularity and signal complexity. The procedure was tested on data from an experiment in which we investigated the impact of native language on tracking to linguistic rhythms in two groups: English natives and Spanish natives. In the experiment, we found no effect of native language but an effect of language rhythm. Here, we compare source projected signals in the auditory areas of both hemispheres for the different conditions using nonparametric permutation tests, modularity, and a dynamical complexity measure. We found increasing values of complexity for decreased regularity in the stimuli, giving us the possibility to conclude that languages with less complex rhythms are easier to track by the auditory cortex.

That means something to me: How linguistic and emotional experience affect the acquisition, representation, and processing of novel abstract concepts.

We used a novel linguistic training paradigm to investigate the experience-dependent acquisition, representation, and processing of novel emotional and neutral abstract concepts. Participants engaged in mental imagery (n = 32) or lexico-semantic rephrasing (n = 34) of linguistic material during five training sessions and successfully learned the novel abstract concepts. Feature production after training showed that specifically emotion features enriched the emotional concepts' representations. Unexpectedly, for participants engaging in vivid mental imagery during training a higher semantic richness of the acquired emotional concepts slowed down lexical decisions. Rephrasing, in turn, promoted a better learning and processing performance than imagery, probably due to stronger established lexical associations. Our results confirm the importance of emotional and linguistic experience and additional deep lexico-semantic processing for the acquisition, representation, and processing of abstract concepts.

Which kind of sameness? Disambiguating two senses of identity with a novel linguistic task.

When people report that a person's identity has changed, what do they mean by this? Recent research has often assumed that participants are indicating a change in numerical, rather than qualitative, identity. Investigations into this matter have been hampered by the fact that English has no clear way to demarcate one type of identity from the other. To resolve this matter, we develop and test a novel task in Lithuanian, which has lexical markers for numerical and qualitative identity. We apply this task to intuitions about changes in moral capacities, which has previously shown to lead to high ratings in identity change. We discover that, when people say that a morally altered person is dramatically different, they mean the person is qualitatively transformed, but numerically intact. We conclude that this methodology is a valuable tool not only for illuminating the specific phenomenon of the moral self, but for general use in studying folk ascriptions of identity persistence.

Probabilistic double hierarchy linguistic Maclaurin symmetric mean-MultiCriteria Border Approximation area Comparison method for multi-criteria group decision making and its application in a selection of traditional Chinese medicine prescriptions.

Traditional Chinese medicine (TCM) has gradually played an indispensable role in people's health maintenance, especially in the treatment of chronic diseases. However, there is always uncertainty and hesitation in the judgment and understanding of diseases by doctors, which affects the status recognition and optimal diagnosis and treatment decision-making of patients. In order to overcome the above problems, we lead into probabilistic double hierarchy linguistic term set (PDHLTS) to accurately describe language information in traditional Chinese medicine and make decisions. In this paper, a multi-criteria group decision making (MCGDM) model is constructed based on the MSM-MCBAC (Maclaurin symmetric mean-MultiCriteria Border Approximation area Comparison) method in the PDHL environment. Firstly, a PDHL weighted Maclaurin symmetric mean (PDHLWMSM) operator is proposed to aggregate the evaluation matrices of multiple experts. Then, combined with the BWM and maximizing deviation method, a comprehensive weight determination method is put forward to calculate the weights of criteria. Furthermore, we propose PDHL MSM-MCBAC method based on the Multi-Attributive Border Approximation area Comparison (MABAC) method and the PDHLWMSM operator. Finally, an example of a selection of TCM prescriptions is used and some comparative analyses are made to verify the effectiveness and superiority of this paper.

Phase-locking of Neural Activity to the Envelope of Speech in the Delta Frequency Band Reflects Differences between Word Lists and Sentences.

The envelope of a speech signal is tracked by neural activity in the cerebral cortex. The cortical tracking occurs mainly in two frequency bands, theta (4-8 Hz) and delta (1-4 Hz). Tracking in the faster theta band has been mostly associated with lower-level acoustic processing, such as the parsing of syllables, whereas the slower tracking in the delta band relates to higher-level linguistic information of words and word sequences. However, much regarding the more specific association between cortical tracking and acoustic as well as linguistic processing remains to be uncovered. Here, we recorded EEG responses to both meaningful sentences and random word lists in different levels of signal-to-noise ratios (SNRs) that lead to different levels of speech comprehension as well as listening effort. We then related the neural signals to the acoustic stimuli by computing the phase-locking value (PLV) between the EEG recordings and the speech envelope. We found that the PLV in the delta band increases with increasing SNR for sentences but not for the random word lists, showing that the PLV in this frequency band reflects linguistic information. When attempting to disentangle the effects of SNR, speech comprehension, and listening effort, we observed a trend that the PLV in the delta band might reflect listening effort rather than the other two variables, although the effect was not statistically significant. In summary, our study shows that the PLV in the delta band reflects linguistic information and might be related to listening effort.

The Evolution of Inclusive Folk-Biological Labels and the Cultural Maintenance of Meaning.

How is word meaning established, and how do individuals acquire it? What ensures the uniform understanding of word meaning in a linguistic community? In this paper I draw from cultural attraction theory and use folk biology as an example domain and address these questions by treating meaning acquisition as an inferential process. I show that significant variation exists in how individuals understand the meaning of inclusive biological labels such as "plant" and "animal" due to variation in their salience in contemporary ethnic minority groups in southwest China, and I present historical textual evidence that the meaning of inclusive terms is often unstable but can be sustained by such cultural institutions as religion and education, which provide situations in which the meaning of linguistic labels can be unambiguously inferred.

An approach to constructing prosodic grammar for Mandarin read speech.

A data-driven approach to constructing a prosodic grammar of Mandarin read speech is proposed. Prosodic labeling is performed, first, on a large speech corpus with syntactic-tree parsing to add four-level break indices. Two types of prosodic grammatical rules are explored. One type is composed of simplified rules to compute break-type distributions at critical junctures for 5 phrase-level and 11 basic syntactic patterns. The other type entails detailed rules to compute break-type distributions conditioned on syntactic function for four determinative-measure (DM)-related syntactic patterns. Effectiveness of the approach was confirmed by meaningful interpretations of the resulting main prosodic patterns and outliers of targeted syntactic patterns by inferred rules. The main findings are given below. Strong paused breaks are found at VE-clause object (VE, active verb with a sentential object) junctures and junctures after idioms. For DM-related patterns, the entropies of break-type distributions decrease significantly as syntactic functions are involved; break-type distributions on both edges are seriously affected by their syntactic functions; when acting as subject (S) and object (O), their prosodic phenomena support the tendency of Mandarin to be S(VO) (V, verb); strong paused breaks at postboundaries of DM-2-DM-4 are caused by their more complex syntactic structures and greater lengths; and the insertions of modifier + DE (special tag for the word DE) into DM-N (N, noun) junctures cause more paused-break insertions at junctures after DMs.

Experience-dependent effects of passive auditory exposure in infants impact theta phase synchrony and predict later language.

The establishment of cortical representations critical for mounting language is supported by both ongoing neural maturation and experience-expectant plasticity as infants increasingly recognize the linguistic events that occur most often in their surrounding environment. Previous research has demonstrated that enhanced efficiency of syllabic representation and discrimination is facilitated by interactive attention-driven, nonspeech auditory experience. However, experience-dependent effects on syllable processing as a function of nonspeech, passive auditory exposure (PAE), remain unclear. As theta band-specific activity has been shown to support syllabic processing, we chose theta inter-trial phase synchrony to examine the experience-dependent effects of PAE on the processing of a syllable contrast. Results demonstrated that infants receiving PAE increased syllabic processing efficiency. Specifically, compared with controls, the group receiving PAE showed more mature, efficient processing, exhibiting less theta phase synchrony for the standard syllable at 9 months, and at 18 months, for the deviant syllable. Furthermore, the PAE modulatory effect on theta phase synchrony at 7 and 9 months was associated with language scores at 12 and 18 months. These findings confirm that supporting emerging perceptual abilities during early sensitive periods impacts syllabic processing efficiency and aligns with literature demonstrating associations between infant auditory perceptual abilities and later language outcomes.

Toad zoonyms mirror the linguistic and demographic history of Greece.

The common toad (Bufo bufo) has been the subject of many folk tales and superstitions in Western Europe, and as a result, it is characterised by numerous common names (zoonyms). However, the zoonyms of the toad and its associated traditions have remained unexplored in the Balkans, one of Europe's linguistic hotspots. In the present study, it was attempted to fill this knowledge gap by focusing on Greece, where more than 7.700 individuals were interviewed both in the field and through online platforms, in order to document toad zoonyms from all varieties and dialects of Greek, as well as local non-Greek languages such as Arvanitika, South Slavic dialects, and Vlach. It was found that the academically unattested zoonyms of the toad provide an unmatched and previously unexplored linguistic and ethnographic tool, as they reflect the linguistic, demographic, and historical processes that shaped modern Greece. This is particularly pertinent in the 21st century, when a majority of the country's dialects and languages are in danger of imminent extinction-and some have already gone silent. Overall, the present study shows the significance of recording zoonyms of indigenous and threatened languages as excellent linguistic and ethnographic tools that safeguard our planet's ethnolinguistic diversity and enhance our understanding on how pre-industrial communities interacted with their local fauna. Furthermore, in contrast to all other European countries, which only possess one or only a few zoonyms for the toad, the Greek world boasts an unmatched 37 zoonyms, which attest to its role as a linguistic hotspot.

Implementation of Japanese Sociocultural Values in Japanese Kotowaza: A Cognitive Linguistics Perspective.

Kotowaza were created by gaining experience and through recurring events over the years of existence of the Japanese people. The purpose of this study is to conduct a qualitative analysis of Japanese kotowaza in cognitive-linguistic discourse to divide idioms into categories and groups with specific sociocultural features. The paper focuses in detail on the semantic features of 20 kotowaza that use animal symbols as an idiomatic metaphor. In this paper, 10 proverbs with the central animal visualization, neko, were analyzed. Visionary metaphors are developed based on the comparison of cat's body parts and behavior with human qualities or characteristics of objects and phenomena. The analysis of the remaining 10 kotowaza showed that the meaning of imagery could originate from Chinese tradition and then change under the influence of Japanese style. Hence, it follows that the meanings of some kotowaza, or the animals they use, can be interpreted differently depending on context. However, the key meanings of proverbs are engrained in the national consciousness of native speakers. It was also observed that kotowaza used oxymoron. It is possible to gain a correct understanding of what kotowaza means through analyzing literal and idiomatic relations in the proverb. Each proverb has an animal symbol, the meaning of which is engrained and originates from the cultural and historical development of the Japanese nation. The practical application of the study lies in the fact that these findings can be used for further study of the special aspects of manifestation of sociocultural heritage at the linguistic level within the phraseology of the Japanese language.

Neural tracking of linguistic and acoustic speech representations decreases with advancing age.

BACKGROUND: Older adults process speech differently, but it is not yet clear how aging affects different levels of processing natural, continuous speech, both in terms of bottom-up acoustic analysis and top-down generation of linguistic-based predictions. We studied natural speech processing across the adult lifespan via electroencephalography (EEG) measurements of neural tracking. GOALS: Our goals are to analyze the unique contribution of linguistic speech processing across the adult lifespan using natural speech, while controlling for the influence of acoustic processing. Moreover, we also studied acoustic processing across age. In particular, we focus on changes in spatial and temporal activation patterns in response to natural speech across the lifespan. METHODS: 52 normal-hearing adults between 17 and 82 years of age listened to a naturally spoken story while the EEG signal was recorded. We investigated the effect of age on acoustic and linguistic processing of speech. Because age correlated with hearing capacity and measures of cognition, we investigated whether the observed age effect is mediated by these factors. Furthermore, we investigated whether there is an effect of age on hemisphere lateralization and on spatiotemporal patterns of the neural responses. RESULTS: Our EEG results showed that linguistic speech processing declines with advancing age. Moreover, as age increased, the neural response latency to certain aspects of linguistic speech processing increased. Also acoustic neural tracking (NT) decreased with increasing age, which is at odds with the literature. In contrast to linguistic processing, older subjects showed shorter latencies for early acoustic responses to speech. No evidence was found for hemispheric lateralization in neither younger nor older adults during linguistic speech processing. Most of the observed aging effects on acoustic and linguistic processing were not explained by age-related decline in hearing capacity or cognition. However, our results suggest that the effect of decreasing linguistic neural tracking with advancing age at word-level is also partially due to an age-related decline in cognition than a robust effect of age. CONCLUSION: Spatial and temporal characteristics of the neural responses to continuous speech change across the adult lifespan for both acoustic and linguistic speech processing. These changes may be traces of structural and/or functional change that occurs with advancing age.

Reflexo e sombra: o duplo e o narcisismo em hoffmann e chamisso / Reflection and shadow: the double and the narcissism in hoffmann and chamisso / Reflejo y penumbra: el doble y el narcisismo en hoffman y chamisso

Esta é uma pesquisa qualitativa, em formato de ensaio, que realiza o estudo comparado de duas obras literárias, de A. Von Chamisso e E. T. A. Hoffmann, e de uma anotação do diário deste último para problematizar a repercussão de algumas formas de desestabilizações do Eu na dinâmica psíquica da neurose. O foco dos textos referidos está no fenômeno do duplo na sua forma negativizada, isto é, como o desaparecimento da imagem exterior que dá suporte ao Eu. As ausências da sombra e do reflexo são entendidas como representações metafóricas de uma alteração do Eu que engendra repercussões importantes na homeostase psíquica, sobretudo nas relações sociais de troca. Explora-se daí a menção no diário de Hoffmann de instrumentos ópticos para interrogar o uso desses aparelhos como modelos metapsicológicos na psicanálise. Salienta-se, ainda, a participação de processos de natureza estética na dinâmica psíquica do infamiliar, tomando como referência a ligação entre o conto de Hoffmann e o relato de Stendhal sobre a sua estadia em Florença.(AU)

This is a qualitative research, in essay format, which performs the comparative study of two literary works, by A. Von Chamisso and E. T. A. Hoffmann, and an annotation in the latter's diary to problematize the repercussion of some forms of destabilization of the Ego's in the psychic dynamics of neurosis. The focus of the referred texts is on the phenomenon of the double in its negative form, that is, as the disappearance of the outer image that supports the Ego. The absences of the shadow and the reflection are understood as metaphorical representations of an alteration of the Ego that generates important repercussions on psychic homeostasis, above all in social relationships of exchange. Thus, we analyze the mention of optical instruments in Hoffmann's diary to question the use of these devices as metapsychological models in psychoanalysis. Note, also, the participation of processes of aesthetic nature in the psychic dynamics of the uncanny, taking as reference the connection between Hoffmann's short story and Stendhal's account of his stay in Florence.(AU)

Los textos se centran en el fenómeno del doble en su forma negativa, como la desaparición de la imagen exterior que sostiene el Yo. Se entienden las ausencias de la penumbra y el reflejo como una representación metafórica de una alteración de la función del Yo que genera importantes repercusiones en la regulación psíquica, sobre todo en las relaciones de intercambio social.

Deep Mobile Linguistic Therapy for Patients with ASD.

Autistic spectrum disorder (ASD) is one of the most complex groups of neurobehavioral and developmental conditions. The reason is the presence of three different impaired domains, such as social interaction, communication, and restricted repetitive behaviors. Some children with ASD may not be able to communicate using language or speech. Many experts propose that continued therapy in the form of software training in this area might help to bring improvement. In this work, we propose a design of software speech therapy system for ASD. We combined different devices, technologies, and features with techniques of home rehabilitation. We used TensorFlow for Image Classification, ArKit for Text-to-Speech, Cloud Database, Binary Search, Natural Language Processing, Dataset of Sentences, and Dataset of Images with two different Operating Systems designed for Smart Mobile devices in daily life. This software is a combination of different Deep Learning Technologies and makes Human-Computer Interaction Therapy very easy to conduct. In addition, we explain the way these were connected and put to work together. Additionally, we explain in detail the architecture of software and how each component works together as an integrated Therapy System. Finally, it allows the patient with ASD to perform the therapy anytime and everywhere, as well as transmitting information to a medical specialist.

African American English speaking 2nd graders, verbal-s, and educational achievement: Event related potential and math study findings.

A number of influential linguistic analyses hold that African American English (AAE) has no verbal-s, the-s that, for example, turns drink into drinks in more mainstream English varieties.On such accounts, sentences like Mary drinks coffee are ungrammatical in AAE. Previous behavioral studies suggest that in addition to being ungrammatical, AAE speaking children find these sentences cognitively demanding, and that their presence in mathematical reasoning tests can depress scores. Until now, however, no online sentence processing study nor investigation of neurophysiological markers has been done to support these findings. Aimed at addressing this gap in the literature, the auditory ERP experiment described herein revealed two different processes associated with AAE speaking 2nd graders listening to this type of sentence: a morphosyntactic structure building problem, reflected in a bilateral early anterior-central negativity; and an increase in working memory load, indicated by a bilateral late long-lasting anterior-central negativity. Study participants also took an orally administered test of math word problems. Consistent with previous findings, results showed they answered fewer questions correctly when those questions contained verbal-s than when they did not.

Cancer and Traditional Plant Knowledge, an Interesting Field to Explore: Data from the Catalan Linguistic Area.

Cancer is the second cause of death in the world and is foreseen to be responsible for about 16 million deaths in 2040. Approximately, 60% of the drugs used to treat cancer are of natural origin. Besides the extensive use of some of these drugs in therapies, such as those derived from the genus Taxus, a significant number of plants have revealed themselves as useful against cancer in recent years. The field of ethnobotany focuses on documenting traditional knowledge associated with plants, constituting a starting point to uncover the potential of new plant-based drugs to treat or prevent, in this case, tumour diseases and side effects of chemotherapy and radiotherapy. From a series of extensive ethnobotanical prospections across the Catalan linguistic area (CLA), we have recorded uses for 41 taxa with antitumour effects. The two most quoted botanical families are Asteraceae and Ranunculaceae, and the most frequently reported species is Ranunculus parnassifolius, a high-mountain species, which is widely collected for this purpose. The reported species have been used to treat an important number of cancer types, focusing on preventive, palliative, and curative uses, as well as to deal with the side effects of conventional treatments. Comparing our results in CLA with previous data available in the most comprehensive databases of pharmacology and a review of cytotoxicity assays revealed that for the several species reported here, there was no previous evidence of traditional uses against cancer. Despite the need for further analyses to experimentally validate the information presented here, combining traditional uses and phylogenetically-informed strategies to phytochemical and pharmacological research would represent new avenues to establish more integrative approaches, hence improving the ability to select new candidate taxa in cancer research.

Ancient and modern genomics of the Ohlone Indigenous population of California.

SignificanceCalifornia supports a high cultural and linguistic diversity of Indigenous peoples. In a partnership of researchers with the Muwekma Ohlone tribe, we studied genomes of eight present-day tribal members and 12 ancient individuals from two archaeological sites in the San Francisco Bay Area, spanning ∼2,000 y. We find that compared to genomes of Indigenous individuals from throughout the Americas, the 12 ancient individuals are most genetically similar to ancient individuals from Southern California, and that despite spanning a large time period, they share distinctive ancestry. This ancestry is also shared with present-day tribal members, providing evidence of genetic continuity between past and present Indigenous individuals in the region, in contrast to some popular reconstructions based on archaeological and linguistic information.

Translation and linguistic validation of the EORTC QLQ-PAN26 questionnaire for assessment of health-related quality of life in patients with pancreatic cancer and chronic pancreatitis into isiXhosa and Afrikaans.

BACKGROUND: Health-related quality of life (HRQOL) parameters have become important components in the holistic management of pancreatic ductal adenocarcinoma (PDAC) and are now increasingly incorporated in treatment protocols. The European Organisation for Research and Treatment of Cancer (EORTC) pancreatic cancer specific questionnaire (QLQ-PAN26) has also been validated for chronic pancreatitis (CP). The objective was to translate the EORTC QLQPAN26 questionnaire into and validate it for isiXhosa and Afrikaans. METHODS: Following the EORTC translation procedure, two forward translations of the English version into isiXhosa and Afrikaans were performed independently by two language practitioners for each language, followed by reconciliation of disagreements. A back translation of the reconciled version into English by a second pair of language practitioners was done. The results of all the steps were summarised with comments in a report for review by the EORTC translation unit. After proofreading by an external proof-reader chosen by the translation unit, pilot testing was performed on a cohort of ten isiXhosa patients and ten Afrikaans patients with PDAC or chronic pancreatitis. Results were summarised in a pilottesting report, and the final version approved by the translation unit. RESULTS: Thirteen patients diagnosed with PDAC and seven with CP were included in the study. The questionnaire was completed electronically (n = 12) or on paper (n = 8). Median age in the isiXhosa group was 53.7 (range 41-63) and in the Afrikaans group 60.9 (range 35-79). Questions 31-54 had a 100% completion rate, while 35% of respondents did not complete Q55 and Q56. Internal consistency was satisfactory in isiXhosa (alpha = 0.88) and Afrikaans (alpha = 0.89). CONCLUSION: The EORTC QLQ-PAN26 used in patients with PDAC and CP has been translated and linguistic validation performed in isiXhosa and Afrikaans. Availability of a questionnaire in patients' mother tongue should increase the validity of results.
