In this cohort study, we evaluated the cognitive and learning difficulties of school-age children perinatally infected with Chikungunya virus (CHIKV) on Reunion Island using the Evaluation of Cognitive Functions and Learning in Children (EDA) battery screening test compared to the healthy children cohort used for EDA development. Of the 19 infected children, 11 (57.9%) exhibited subnormal or abnormal scores, of whom 3 were classified as high risk, and 8 were classified as at risk for cognitive and learning difficulties. Children who had encephalopathy were at higher risk for displaying at least one difficulty than non-encephalopathic children (relative risk 2.13; 95% CI 1.05–4.33). The difficulties observed affected verbal functions, non-verbal functions, and learning abilities, such as phonology, lexical evocation and comprehension, graphism, selective visual attention, planning, visual–spatial reasoning, dictation and mathematics, as well as core executive functions, such as inhibitory control, shifting, and working memory. Neurocognitive dysfunctions could be linked to severe brain damage, as evidenced by severe white matter reduction mainly in the frontal lobes and corpus callosum and potentially in all functional networks involved in difficulties. These results should motivate further investigation of intellectual and adaptive functioning to diagnose intellectual deficiency and severe maladaptive behaviour in children perinatally infected with Chikungunya virus.

Children’s consonant cluster productions in typical and atypical phonological development were investigated for different languages reporting developmental productions that are universal, language-specific, and/or child-specific. These patterns are often interpreted considering sonority hierarchy effects. Quantitative norms on developmental cluster productions are less prevalent in the literature cross-linguistically, as are investigations on the development of less frequent cluster types in the world’s languages, like those involving falling and level sonority two-member onsets. Our study contributes to these investigations, focusing on Greek-specific onsets: falling sonority obstruents [ft, xt], level sonority obstruents [fθ, fç, ðʝ, xθ, ɣð], and level sonority nasals [mɲ]. We present cross-sectional, longitudinal data from 90 monolingual children, aged 2;0–4;0, based on the word elicitation task, Phonological Assessment for Greek (PAel). As only [ft] 89%, [fç] 80%, [mɲ] 88% are acquired by 3;6–4;0, the data provide evidence that [ft, xt, fθ, xθ, ɣð] reduce to C2, [mɲ] reduces to C1, and [fç], [ðʝ] show the most variability in reduction/simplification patterns. Reduction patterns largely reflect individual cluster acquisition paths longitudinally; the relative reduction to a member changes with age, but the preference to the member does not, except for [ðʝ]. The data facilitate the establishment of quantitative markers for cluster development and qualitative interpretations in terms of featural and structural prominence, including a veiled sonority effect not previously reported in the literature.

We present acoustic and articulatory data from an experiment designed to test the phonetic variability of rhotics in Brazilian Portuguese, focusing on the São Paulo variety. Ultrasound tongue imaging was used to examine the realisation of rhotics in a range of phonological environments. Our analysis reveals that word-initial and intervocalic fricatives are acoustically and articulatorily distinct for most speakers. We attribute a tendency for utterance-initial fricatives to display longer duration, less voicing, and greater tongue-dorsum displacement than word-medial intervocalic counterparts to phonetic enhancement at the site of a major prosodic boundary. Similarly, rhotic taps in utterance-final position show a tendency for devoicing and frication (aspiration or assibilation) speaker-dependently. By comparison, word-medial pre-consonantal and intervocalic taps are characterised by shorter durations and greater voicing: hence, a pattern of phonetic reduction in prosodically weaker environments. We relate our findings to theoretical debates around the phonological status of rhotics in Portuguese. Whilst not providing conclusive proof in favour of any one particular approach, our results highlight the need to recognise the reality of prosodically driven strengthening in developing a full account of rhotic variation in the variety.

It is widely accepted that languages organize speech material into prosodic domains, which are hierarchically arranged. However, it is still a matter of debate whether this prosodic hierarchy is composed of a small number of universal categories, or whether these prosodic categories are language-particular and emergent. In this article, we concentrate on one of these categories, the foot, and we investigate its role in European Portuguese (EP). Whereas research on EP has shown that other prosodic domains commonly found crosslinguistically are active in the language, it seems that EP may lack this prosodic constituent. Therefore, the goal of this article is to systematically investigate the role of the foot in a number of areas within EP grammar. In our study, we defend some new approaches to several long-standing issues in EP phonology and we conclude that many facts of the language can be, in fact, better understood resorting to the foot domain. Namely, the distribution of stress in the most frequent morphological classes (thematic non-verbs and present tense verbs), -inh-/-zinh- diminutive formation, the domain for regular vowel reduction, obligatory glide formation, the stress window, and poetic rhyme seem to benefit from a metrically-governed account. By contrast, other facts, such as vowel lowering, word clipping, minimal words, secondary stress, and schwa deletion are shown not to be conditioned by the foot in EP. Importantly, the evidence we found for metrical structure only cues the prominent foot of the word, suggesting that pretonic material may not be footed. All in all, in addition to shedding light on facts previously poorly understood, and exposing some noteworthy specificities of EP in the realm of Romance languages and other varieties of Portuguese, we draw implications for the universal characterization of the prosodic hierarchy and its acquisition.

The rebranding of reggaetón towards Latin urban has been criticized for tokenizing Afro-Caribbean linguistic and cultural practices as symbolic resources recruitable by non-Caribbean artists/executives in the interest of profit. Consumers are particularly critical of an audible phonological homogeneity in the performances of ethnonationally distinct mainstream performers, framed as a form of linguistic minstrelsy popularly termed a ‘Caribbean Blaccent’ that facilitates capitalization on the genre’s popularity by tapping into the covert prestige of distinctive phonological elements of Insular Caribbean Spanish otherwise stigmatized. This work pairs acoustic analysis with quantitative statistical modeling to compare the use of lenited coronal sibilant allophones popularly considered indexical of Hispano-Caribbean origins in the spoken and sung speech of four of the genre’s top-charting female performers. A general pattern of style-shifting from interview to sung speech wherein sibilance is favored in the former and phonetic zeros in the latter is revealed. Moreover, a statistically significant increased incidence of [-] across time shows the most recent records to uniformly deploy near-categorical reduction independent of artists’ sociocultural and linguistic backgrounds. The results support the enregisterment of practices popularized by the genre’s San Juan-based pioneers as a stylistic resource—a reggaetón voice—for engaging the images of vernacularity sustaining and driving the contemporary, mainstream popularity of música urbana.

Accounts of phonological contrast traditionally invoke a binary distinction between unpredictable lexically stored phonemes and contextually predictable allophones, whose patterning reveals speakers’ knowledge about their native language. This paper explores the complexity of contrasts among Italian mid vowels from a multifaceted perspective considering the lexicon, linguistic structure, usage, and regional variety. The Italian mid vowels are marginally contrastive due to a scarcity of minimal pairs alongside variation in phonetic realization. The analysis considers corpus data, which indicate that the marginal contrasts among front vowels vs. back vowels are driven by different sources and forces. Functional loads are low; while front /e ɛ/ have the weakest lexical contrast among all Italian vowels, back /o ɔ/ are separated by somewhat more minimal pairs. Among stressed front vowels, height is predicted by syllable structure and is context-dependent in some Italian varieties. Meanwhile, the height of back mid vowels is predicted by lexical frequency, in line with expectations of phonetic reduction in high-frequency contexts. For both front and back vowels, the phonetic factor of duration predicts vowel height, especially in closed syllables, suggesting its use for contrast enhancement. The results have implications for a proposed formalization of Italian mid vowel variation. Full article

This study empirically investigates functional and social variation in the use of TAYYIB (‘okay, well, right’) in light of grammaticalisation. Thirty naturally occurring conversations of 60 Najdi Arabic speakers were recorded in Riyadh, Saudi Arabia. The analysis demonstrates that TAYYIB has two realisations: full Tayyib [tˁajjib] and reduced Tab [tˁab]. Drawing on the conversation analytic approach within a variationist framework, TAYYIB was used to perform multiple discourse-pragmatic functions: interpersonal, textual and interpersonal–textual. The statistical analysis reveals that variant choice is significantly conditioned by the pragmatic functions. While Tayyib is employed to perform all three functions, Tab is only used for textual and interpersonal–textual meanings. As for social factors, Tab is significantly more likely to be used by younger speakers than adults and also more likely to be used by females than males. This can be interpreted as an indication of ongoing change driven by young people, primarily females, towards the greater use of the innovative Tab. Given the evidence of linguistic change in Tab including semantic bleaching, pragmatic strengthening and phonological reduction, the study suggests that Tab has undergone advanced grammaticalisation.

This study describes the segmental and suprasegmental phonology of Adur Niesu, a Loloish (or Ngwi) language spoken mainly in Liangshan, Sichuan, southwest China. Phonemically, there are 41 consonants, 10 monophthongs and 1 diphthong in Adur Niesu. All Adur syllables are open. Its segmental changes mainly happen to the vowels, featuring high vowel fricativization, vowel lowering, vowel centralization, vowel assimilation and vowel fusion. It is common for Adur Niesu syllables to be reduced in continuous speech, with floating tones left. There are three main types of syllable reduction: complete reduction including the segment and tone, partial reduction with a floating tone left, and partial reduction with the initial consonant left. Adur Niesu employs tones as an important means for lexical contrast, namely, high-level tone 55, mid-level tone 33, and low-falling tone 21. There is also a sandhi tone 44. There are two types of tonal alternation: tone sandhi and tone change. Tone sandhi occurs at both word and phrasal levels, and is conditioned by the phonetic environment, while tone change occurs due to the morphosyntactic environment. Finally, some seeming tonal alternation is the result of a floating tone after syllable reduction. Full article

By conducting an apparent-time analysis of the OFROM corpus collected in Francophone Switzerland, this study examined the use of genre as discourse marker in the speech of 306 French L1 speakers. First, we examined the effect of extralinguistic factors on the discursive use of genre. The logistic mixed-effects regression analysis results revealed that the emerging use of genre is indeed an ongoing change led by female speakers in Swiss French. This use was favored by monolinguals in Francophone Swiss. Second, we examined the vowel reduction of the DM genre in the corpus. Our results revealed that speakers who received only a high school education favor the vowel reduction in the DM genre the most. Given the high percentage of phonological reduction in the DM genre, we believe that the grammaticalization of this particle has reached its advanced stage in Swiss French. Compared to previous findings on the emerging use of genre in Hexagonal French, we suggested that the grammaticalization of the particle genre in Swiss French may be independent of that in Hexagonal French. The grammaticalization in Swiss French was much more advanced than in Hexagonal French. This study supplied comparable results on the grammaticalization of the same particle in two different Francophone countries. Full article

It is already known the effectiveness of Pilates training on cognitive and functional abilities. It is also known that dual-task exercise and cognitive stimuli improve cognition and functional capacity. However, no previous report combined cognitive stimuli and Pilates in dual task and measured its effects on the cognitive and physical performances of postmenopausal women. Objective: To apply an interventional dual-task (PILATES-COG) protocol and to evaluate its influence on memory, language, and functional physical performances on healthy, community-dwelling postmenopausal older women. Methods: 47 women with amenorrhea for at least 12 months participated in this study. Those allocated on the PILATES-COG group underwent a 12-week, twice a week regimen of 50 min sessions of simultaneous mat Pilates exercise program and cognitive tasks. Cognitive and physical functional performance were assessed. Two-way mixed ANOVA was used for data analysis, and Bonferroni post hoc tests were used for within- and between-group comparisons. Results: The PILATES-COG group showed significant improvement after the intervention in semantic verbal fluency (p < 0.001; ηρ² = 0.268), phonological verbal fluency (p < 0.019; ηρ² = 0.143), immediate memory (p < 0.001; ηρ² = 0.258), evocation memory (p < 0.001 ηρ² = 0.282), lower-limb muscle strength (p < 0.001; ηρ² = 0.447), balance (p < 0.001; ηρ² = 0.398), and dual-ask cost (p < 0.05; ηρ² = 0.111) assessments on healthy, community-dwelling postmenopausal older women. Conclusion: This is the first report of a feasible and effective approach using Pilates and cognitive stimulation in dual task for the reduction of age-related cognitive decline and the improvement of physical functional performance in healthy postmenopausal women.

Background: The treatment of functional speech sound disorders (SSDs) in children is often lengthy, ill-defined, and without satisfactory evidence of success; effectiveness studies on SSDs are rare. This randomized controlled trial evaluates the effectiveness of the integrated SSD treatment program PhonoSens, which focuses on integrating phonological and phonetic processing according to the Integrated Psycholinguistic Model of Speech Processing (IPMSP). Methods: Thirty-two German-speaking children aged from 3.5 to 5.5 years (median 4.6) with functional SSD were randomly assigned to a treatment or a wait-list control group with 16 children each. All children in the treatment group and, after an average waiting period of 6 months, 12 children in the control group underwent PhonoSens treatment. Results: The treatment group showed more percent correct consonants (PCC) and a greater reduction in phonological processes after 15 therapy sessions than the wait-list control group, both with large effect sizes (Cohen’s d = 0.89 and 1.04). All 28 children treated achieved normal phonological abilities: 21 before entering school and 7 during first grade. The average number of treatment sessions was 28; the average treatment duration was 11.5 months. Conclusion: IPMSP-aligned therapy is effective in the treatment of SSD and is well adaptable for languages other than German. Full article

Apocope (deletion of word-final vowels) and word-final vowel reduction are hallmarks of southern Italian varieties. To investigate whether heritage speakers reproduce the complex variable patterns of these processes, we analyze spontaneous speech of three generations of heritage Calabrian Italian speakers and a homeland comparator sample. All occurrences (N = 2477) from a list of frequent polysyllabic words are extracted from 25 speakers’ interviews and analyzed via mixed effects models. Tested predictors include: vowel identity, phonological context, clausal position, lexical frequency, word length, gender, generation, ethnic orientation and age. Homeland and heritage speakers exhibit similar distributions of full, reduced and deleted forms, but there are inter-generational differences in the constraints governing the variation. Primarily linguistic factors condition the variation. Homeland variation in reduction shows sensitivity to part of speech, while heritage speakers show sensitivity to segmental context and part of speech. Slightly different factors influence apocope, with suprasegmental factors and part of speech significant for homeland speakers, but only part of speech for heritage speakers. Surprisingly, for such a socially marked feature, few social factors are relevant. Factors influencing reduction and apocope are similar, suggesting the processes are related. Full article

Human activities have substantially altered present-day flow regimes. The Headwater Area of the Yellow River (HAYR, above Huanghe’yan Hydrological Station, with a catchment area of 21,000 km² and an areal extent of alpine permafrost at ~86%) on the northeastern Qinghai-Tibet Plateau, Southwest China has been undergoing extensive changes in streamflow regimes and groundwater dynamics, permafrost degradation, and ecological deterioration under a warming climate. In general, hydrological gauges provide reliable flow records over many decades and these data are extremely valuable for assessment of changing rates and trends of streamflow. In 1998–2003, the damming of the Yellow River by the First Hydropower Station of the HAYR complicated the examination of the relations between hydroclimatic variables and streamflow dynamics. In this study, the monthly streamflow rate of the Yellow River at Huanghe’yan is reconstructed for the period of 1955–2019 using the double mass curve method, and then the streamflow at Huagnhe’yan is forecasted for the next 20 years (2020–2040) using the Elman neural network time-series method. The dam construction (1998–2000) has caused a reduction of annual streamflow by 53.5–68.4%, and a more substantial reduction of 71.8–94.4% in the drier years (2003–2005), in the HAYR. The recent removal of the First Hydropower Station of the HAYR dam (September 2018) has boosted annual streamflow by 123–210% (2018–2019). Post-correction trends of annual maximum (Q_Max) and minimum (Q_Min) streamflow rates and the ratio of the Q_Max/Q_Min of the Yellow River in the HAYR (0.18 and 0.03 m³·s⁻¹·yr⁻¹ and −0.04 yr⁻¹, respectively), in comparison with those of precorrection values (−0.11 and −0.004 m³·s⁻¹·yr⁻¹ and 0.001 yr⁻¹, respectively), have more truthfully revealed a relatively large hydrological impact of degrading permafrost. Based on the Elman neural network model predictions, over the next 20 years, the increasing trend of flow in the HAYR would generally accelerate at a rate of 0.42 m³·s⁻¹·yr⁻¹. Rising rates of spring (0.57 m³·s⁻¹·yr⁻¹) and autumn (0.18 m³·s⁻¹·yr⁻¹) discharge would see the benefits from an earlier snow-melt season and delayed arrival of winter conditions. This suggests a longer growing season, which indicates ameliorating phonology, soil nutrient availability, and hydrothermal environments for vegetation in the HAYR. These trends for hydrological and ecological changes in the HAYR may potentially improve ecological safety and water supplies security in the HAYR and downstream Yellow River basins. Full article

Japanese learners of English can acquire /r/ and /l/, but discrimination accuracy rarely reaches native speaker levels. How do L2 learners develop phonological categories to acquire a vocabulary when they cannot reliably tell them apart? This study aimed to test the possibility that learners establish new L2 categories but perceive phonological overlap between them when they perceive an L2 phone. That is, they perceive it to be an instance of more than one of their L2 phonological categories. If so, improvements in discrimination accuracy with L2 experience should correspond to a reduction in overlap. Japanese native speakers differing in English L2 immersion, and native English speakers, completed a forced category goodness rating task, where they rated the goodness of fit of an auditory stimulus to an English phonological category label. The auditory stimuli were 10 steps of a synthetic /r/–/l/ continuum, plus /w/ and /j/, and the category labels were L, R, W, and Y. Less experienced Japanese participants rated steps at the /l/-end of the continuum as equally good versions of /l/ and /r/, but steps at the /r/-end were rated as better versions of /r/ than /l/. For those with more than 2 years of immersion, there was a separation of goodness ratings at both ends of the continuum, but the separation was smaller than it was for the native English speakers. Thus, L2 listeners appear to perceive a phonological overlap between /r/ and /l/. Their performance on the task also accounted for their responses on /r/–/l/ identification and AXB discrimination tasks. As perceived phonological overlap appears to improve with immersion experience, assessing category overlap may be useful for tracking L2 phonological development. Full article
