Secuencia evolutiva del conocimiento fonológico en niños prelectores
2014
Resumen El trabajo trata sobre el conocimiento fonologico y sus niveles de adquisicion en ninos prelectores. Se ha aplicado la prueba Bateria de Inicio a la Lectura (BIL 3-6), que evalua las habilidades relacionadas con una adquisicion exitosa de la lectura. Esta bateria es un instrumento util para las escuelas de educacion infantil, en los anos previos al inicio del aprendizaje de la lectura, y presenta las siguientes subpruebas de conocimiento fonologico: rima, contar palabras, contar silabas, aislar silabas y fonemas —principio de palabra— y omision de silabas. La prueba se aplico a una muestra representativa de 344 ninos espanoles con edades comprendidas entre los 3 y los 6 anos. Esto h…
Relationship between speech perception and production skills and morphosyntactic development in Spanish-speaking children with Speech Sound Disorders
2021
La investigación sobre el desarrollo gramatical y su posible relación con los déficits de procesamiento de habla en niños con Trastorno Fonológico (TF) es escasa, especialmente para la lengua española. El objetivo es analizar la influencia de las habilidades de percepción y producción de habla en el desarrollo morfosintáctico de los niños con TF sin Trastorno del Lenguaje (TL). Participaron 52 niños de habla española de 4 a 6 años: 26 con TF y 26 con desarrollo típico (DT) emparejados en edad cronológica, cociente de inteligencia no verbal y nivel de vocabulario receptivo. El desarrollo morfosintáctico se evaluó con el test de lenguaje CELF-Preschool-2-Spanish. Los niños realizaron una tare…
Profiling deaf and hard-of-hearing users of subtitles for the deaf and hard-of-hearing in Italy: a questionnaire-based study
2012
The aim of this article is to present the results of a questionnaire-based study carried out as part of the author’s Master’s Degree dissertation about Subtitles for the Deaf and Hard-of-hearing (SDH). In particular, the need to gather specific information regarding audience design will be highlighted in the paper, since this research field has long been neglected in Italy. The questions were aimed at shedding light on the needs, cultural environment and world-view of Italian SDH users, by eliciting personal data as well as subtitlerelated information. Moreover, the 232 respondents were asked to suggest improvements to SDH services in Italy. Although these first results cannot allow definit…
Language Development and Symbolic Play in Children With and Without Familial Risk for Dyslexia
2001
The purposes of this study were to investigate (a) whether children in families with a positive history of dyslexia were more likely to show delays in language development than children without family risk and (b) whether a delayed onset of expressive language (late talking) predicted later language development. We analyzed the language development of 200 children longitudinally at 14, 24, 30, and 42 months and assessed their symbolic play at 14 months. Half of the children ( N =106) were from families with a history of dyslexia (the Dyslexia Risk [DR] group), and other children served as age-matched controls. Parental reports and structured tests were used to assess children’s receptive a…
On thrusting, regional unconformities and exhumation of high-grade greenstones in Neoarchean orogens. The case of the Waroonga Shear Zone, Yilgarn Cr…
2017
Abstract During the Neoarchean, the dominant tectonic style progressively changed from an episodic-overturn/stagnant-lid regime to modern-style plate tectonics. The Neoarchean strengthening of continental lithosphere changed the style of deformation of orogenic belts. The case study presented here provides insights into how such transition in tectonic style occurred, a matter that is generally controversial. We present structural and metamorphic data from the c. 2660 Ma Waroonga Shear Zone (WSZ) in the Neoarchean Yilgarn orogen (Western Australia). The WSZ contains a syntectonic pluton and older, high-grade greenstones. The tectonic fabric in the pluton developed during melt-present thrusti…
Tinnitus e Sordità
2010
OBIETTIVI Con il termine di "Acufene" o "Tinnitus" definiamo la percezione di un rumore in assenza di qualunque sorgente sonora esterna al nostro organismo. La presenza di acufeni aumenta progressivamente con l'età (12% dopo i 60 anni), e questo, secondo gli Autori, non è tanto correlato con la senescenza quanto con la concomitante sordità, la cui prevalenza aumenta con l'età. L'obiettivo di questo studio è quello di mettere in evidenza la correlazione fra il tipo di sordità e il tipo di acufene. MATERIALI Lo studio è stato condotto dalla Sezione di Audiologia del Dipartimento di Bio‐technologie dell'Università di Palermo su 197 soggetti affetti da acufene e sordità. I pazienti sono stati s…
Audiologic profile of OSAS and simple snoring patients: the effect of chronic nocturnal intermittent hypoxia on auditory function
2016
The objective of this work was to study the effect of nocturnal intermittent hypoxia on auditory function of simple snoring patients and subjects affected by OSAS; we compared the audiologic profile with the severity of OSAS to detect early signs of cochlear damage. One hundred-sixty patients underwent overnight polysomnography, micro-otoscopy, multi-frequency audiometry, acufenometry, TEOAE recording and d-ROMs test. All subjects were divided in four groups, based on presence/absence of AHI (simple snoring without OSAS, mild OSAS, moderate OSAS, severe OSAS). Sixty (37.5 %) patients were not affected by OSAS, 58 (36.25 %) presented a mild OSAS, 18 (11.25 %) a moderate OSAS and 24 (15 %) a …
Investigation of Tinnitus Patients in Italy: Clinical and Audiological Characteristics
2010
Objective. 312 tinnitus sufferers were studied in order to analyze: the clinical characteristics of tinnitus; the presence of tinnitus-age correlation and tinnitus-hearing loss correlation; the impact of tinnitus on subjects' life and where possible the etiological/predisposing factors of tinnitus.Results. There is a slight predominance of males. The highest percentage of tinnitus results in the decades 61–70. Of the tinnitus sufferers, 197 (63.14%) have a hearing deficit (light hearing loss in 37.18% of cases). The hearing impairment results of sensorineural type in 74.62% and limited to the high frequencies in 58.50%. The tinnitus is referred as unilateral in 59.93%, a pure tone in 66.99%…
Habilidades matemáticas tempranas en niños chilenos con Trastorno del Desarrollo del Lenguaje: Un estudio comparativo
2021
En las últimas décadas se ha incrementado el interés de las investigaciones respecto a las dificultades académicas que presentan los niños con Trastorno del Desarrollo del Lenguaje (TDL). No obstante, su relación con las habilidades matemáticas es una de las menos estudiadas. El objetivo de este estudio consistió en determinar si existen diferencias relevantes entre las habilidades matemáticas tempranas de niños con TDL y con desarrollo típico (DT). Participaron 78 niños de 4 a 7 años 11 meses de edad, pertenecientes a colegios con programas de integración escolar de Santiago de Chile. Se conformó un grupo de 44 niños con TDL y un grupo de 34 con DT. Se establecieron comparaciones del rendi…
Prótesis auditiva osteointegrada “BAHA” : evaluación de los resultados con diferentes técnicas de colgajo
2012
INTRODUCCION La primera prótesis BAHA se coloca en 1.977, con idea de conseguir una mejora auditiva, aprovechando la transmisión ósea directa. La inseguridad inicial motivada por los posibles fallos en los resultados tanto de integración ósea como funcionales se fueron venciendo con el paso del tiempo a la vez que fueron disminuyendo las complicaciones quirúrgicas observadas. La integración ósea de un material inerte como el titanio, supuso muchos estudios histológicos, de biocompatibilidad, de parámetros como duración o tiempo necesario para una buena integración, o de espesor y calidad de hueso imprescindible. Tras obtener progresivamente mejores resultados funcionales, aumentó el grado d…
