Familiarity changes as a function of perceptual shifts.
2010
This experiment compares the yes-no and forced recognition tests as methods of measuring familiarity. Participants faced a phase of 3 study-test recognition trials in which they studied words using all the letters of the alphabet (overlapping condition, O), and an additional phase in which targets and lures did not share any letters (non-overlapping condition, NO). Finally, subjects performed a forced-choice task in which they had to choose one of two new words, each from one of the subsets (Parkin et al., 2001). Results in the NO condition higher than .50, showing their sensitivity to familiarity. When the letter set of the words for study in the third list of the NO condition was swit…
O galego-português, matriz do mundo lingüístico luso-brasileiro
2021
O período inicial desta breve história da língua galega e o reintegracionismo lingüístico começa com umhas observaçons de umha «Carta» de Martim Sarmiento (1695-1771), precursor da filologia galega, e finaliza em 2019, ano em que a Real Academia Galega (RAG), toma o acordo de dedicar-lhe o «Dia das Letras Galegas» ao polígrafo ferrolano Ricardo Carvalho Calero (Ferrol 1910 - Santiago de Compostela 1990). Elaboram-se apenas umhas ideias sobre o século XIX e primeira metade do XX; mais informaçom aparece sobre a segunda metade do século passado e primeiras décadas do XXI.
Idiomatic intonation and forensic phonetics: sociolinguistic and dialectal information from intonation in Spanish
2015
Las investigaciones de carácter geoprosódico realizadas sobre el español y sus variedades ponen en evidencia que la entonación puede reportar importantes beneficios a la fonética forense, ya que esta lleva asociada información de carácter dialectal y sociolingüístico de especial relevancia sobre el individuo –grupo sociocultural al que pertenece, origen geográfico, medio social en el que se inserta–, además de otros rasgos, cualidades o circunstancias como la edad, el sexo, o incluso su temperamento, carácter o estado de ánimo. Para ello se hace necesario no solo saber qué parámetros acústicos suprasegmentales son relevantes para la identificación del hablante, sino también analizar la vari…
On stress production in whispered Finnish
1987
We have compared sentence stress production in normal phonation and whisper in two native speakers of Finnish using acoustical analysis, esophageal pressure measurements and electromyography. The average peak values of the fundamental frequency, intensity, esophageal pressure and the EMG recordings from the thyroarytenoid and cricothyroid muscles were measured and their intercorrelations were calculated. In normal speech the cricothyroid activity and the subglottal pressure showed a significant correlation with the peak values of the acoustical indicators of stress for both subjects. The thyroarytenoid muscle showed a statistically significant correlation with the fundamental frequency for …
Acoustic properties and perception of minimal contrasts in Valencian Catalan sibilants
2017
El valencià estàndard presenta tres consonants fricatives sibilants: /s/, /z/ i /S/.Mentre que el contrast entre /z/ i /s/ sembla indiscutible, l’existència d’unaoposició real entre /S/ i /s/ és més dubtosa. El primer objectiu d’aquest treball éscomprovar si, en un estil de parla hiperarticulat (Fonet, Gonzàlvez et al., 2007), laconsonant /s/ és diferent de /z/ i de /S/ tenint en compte set paràmetres acústics:durada, harmonicitat, pic espectral i quatre moments espectrals: centre de gravetat,desviació estàndard, asimetria i curtosi. Les dades revelen que /z/ i /s/ contrastenclarament en durada, harmonicitat i asimetria; /S/ i /s/ contrasten en harmonicitat,desviació estàndard, curtosi i, e…
Auditory event-related potentials measured in kindergarten predict later reading problems at school age.
2013
Identifying children at risk for reading problems or dyslexia at kindergarten age could improve support for beginning readers. Brain event-related potentials (ERPs) were measured for temporally complex pseudowords and corresponding non-speech stimuli from 6.5-year-old children who participated in behavioral literacy tests again at 9 years in the second grade. Children who had reading problems at school age had larger N250 responses to speech and non-speech stimuli particularly at the left hemisphere. The brain responses also correlated with reading skills. The results suggest that atypical auditory and speech processing are a neural-level risk factor for future reading problems. [Supplement…
Reading skill and neural processing accuracy improvement after a 3-hour intervention in preschoolers with difficulties in reading-related skills
2012
This study aimed at determining whether an intervention game developed for strengthening phonological awareness has a remediating effect on reading skills and central auditory processing in 6-year-old preschool children with difficulties in reading-related skills. After a 3-hour training only, these children made a greater progress in reading-related skills than did their matched controls who did mathematical exercises following comparable training format. Furthermore, the results suggest that this brief intervention might be beneficial in modulating the neural basis of phonetic discrimination as an enhanced speech-elicited mismatch negativity (MMN) was seen in the intervention group, indic…
A computer-based Pinyin intervention for disadvantaged children in China: Effects on Pinyin skills, phonological awareness, and character reading.
2019
Pinyin is an alphabetic script that denotes pronunciations of Chinese characters. Studies have shown that Pinyin instruction enhances both phonological awareness (e.g., Shu et al., Developmental Science, 2008, 11, 171-181) and character reading (e.g., Lin et al., Psychological Science, 2010, 21, 1117-1122) in Chinese children. In the present study, we provided a 3-week Pinyin intervention with a computer-based Pinyin GraphoGame to disadvantaged migrant children with poor Pinyin skills. A total of 252 first graders who were children of migrant workers in a large Chinese city were assessed to identify poor Pinyin readers. Fifty-six 7-year-old children with poor Pinyin skills were selected and…
Does Tonal Information Affect the Early Stages of Visual-Word Processing in Thai?
2014
Thai offers a unique opportunity to investigate the role of lexical tone processing during visual-word recognition, as tone is explicitly expressed in its script. In order to investigate the contribution of tone at the orthographic/phonological level during the early stages of word processing in Thai, we conducted a masked priming experiment—using both lexical decision and word naming tasks. For a given target word (e.g., ห้อง/hᴐ:ŋ2/, room), five priming conditions were created: (a) identity (e.g., ห้อง/hᴐ:ŋ2/), (b) same initial consonant, but with a different tone marker (e.g., ห่อง/hᴐ:ŋ1/), (c) different initial consonant, but with the same tone marker (e.g., ศ้อง/sᴐ:ŋ2/), (d) orthograph…
Event-Related Potentials and Consonant Differentiation in Newborns with Familial Risk for Dyslexia
2004
We measured event-related potentials (ERPs) to synthetic consonant-vowel syllables (/ba/, /da/, /ga/) from 26 newborns with familial risk for dyslexia and 23 control infants participating in the Jyväskylä Longitudinal Study of Dyslexia. The syllables were presented with equal probability and with interstimulus intervals ranging from 3,010 to 7,285 ms. Analyses of averaged ERPs from the latencies identified on the basis of principal component analysis (PCA) revealed significant group differences in stop-consonant processing in several latency ranges. At the latencies of 50-170 ms and 540-630 ms, the responses to /ga/ were larger and more positive than those to /ba/ and /da/ in the right hem…
