Marginaalin ääni perusasteen jälkeisen koulutuksen kehittämisessä: Kuurojen ja huonokuuloisten opiskelijoiden kaksi koulutussukupolvea

2006

”Ruotsalaisten ja yhdysvaltalaisten tutkimusten mukaan kuurojen ja huonokuuloisten aikuisten koulutustaso, työllisyystilanne ja sosiaalinen asema ovat muuttuneet sukupolvesta toiseen siirryttäessä. Koulutus on ollut tärkeä tekijä sosiaalisen aseman muutoksessa. Näin ei vielä ole tapahtunut oppimisyhteiskunnan mallimaassa, Suomessa”, aiheesta väitellyt Elina Lehtomäki kirjoittaa. nonPeerReviewed

Funciones ejecutivas, comprensión de historias y coherencia narrativa en niños con trastorno por déficit de atención con hiperactividad

2010

Resumen Investigaciones previas senalan que los ninos con trastorno por deficit de atencion con hiperactividad (TDAH) tienen dificultades especificas en la narracion de historias, especialmente si la tarea narrativa requiere planificacion y control del tiempo. Sus narraciones estan menos organizadas que las de ninos con un desarrollo tipico, lo cual puede deberse a fallos en el sistema de funcionamiento ejecutivo, un problema central del TDAH. El objetivo de este trabajo fue examinar la influencia de las funciones ejecutivas en la comprension de historias y en la coherencia narrativa en una muestra de 26 ninos con un diagnostico clinico de TDAH. Despues de escuchar una historia compleja con…

Revista de logopedia, foniatría y audiología

2013

Resumen El objetivo del presente estudio fue averiguar si la informacion que proporcionan las pruebas ABX y AX sobre la percepcion de sonidos del habla en una muestra de ninos con trastornos del habla es la misma o no. Participaron 86 ninos de edades comprendidas entre los 3 anos y 2 meses y los 5 anos y 11 meses, siendo la media de 4 anos y 7 meses. Fueron seleccionados de entre una muestra de 1.283 ninos procedentes de 11 colegios diferentes de la Comunitat Valenciana cuya lengua materna era el espanol. En primer lugar se evaluo la produccion del habla. En funcion de los errores cometidos por cada nino, se construyeron y aplicaron las pruebas ABX y AX, utilizando los criterios de Locke pa…

Sensorineural Hearing Loss: Pathophysiology, Diagnosis and Treatment [Chapter 5. Neuroradiology of the Hearing System]

2019

Hearing loss is one of the most frequent indications for CT and MR examinations of the auditory system. Such a symptomatology is becoming increasingly common in today’s society and is extremely disturbing for patients. Causes may involve the auditory pathway at any level. In most cases, neuroradiological examinations represents a mandatory step, within a multidisciplinary workup, towards final diagnosis, therapeutic plan and subsequent follow-ups. This chapter will introduce this critical topic starting from an imaging-based exposition of the anatomy and function of the auditory system. The chapter will include some hints on the choice of the best imaging examination to perform on each pati…

Echolocating Whales and Bats Express the Motor Protein Prestin in the Inner Ear: A Potential Marker for Hearing Loss.

2020

Prestin is an integral membrane motor protein located in outer hair cells of the mammalian cochlea. It is responsible for electromotility and required for cochlear amplification. Although prestin works in a cycle-by-cycle mode up to frequencies of at least 79 kHz, it is not known whether or not prestin is required for the extreme high frequencies used by echolocating species. Cetaceans are known to possess a prestin coding gene. However, the expression and distribution pattern of the protein in the cetacean cochlea has not been determined, and the contribution of prestin to echolocation has not yet been resolved. Here we report the expression of the protein prestin in five species of echolo…

Task-oriented reading efficiency : interplay of general cognitive ability, task demands, strategies and reading fluency

2022

AbstractThe associations among readers’ cognitive skills (general cognitive ability, reading skills, and attentional functioning), task demands (easy versus difficult questions), and process measures (total fixation time on relevant and irrelevant paragraphs) was investigated to explain task-oriented reading accuracy and efficiency (number of scores in a given time unit). Structural equation modeling was applied to a large dataset collected with sixth-grade students, which included samples of dysfluent readers and those with attention difficulties. The results are in line with previous findings regarding the dominant role of general cognitive ability in the accuracy of task-oriented reading…

The precursors of double dissociation between reading and spelling in a transparent orthography.

2016

Research and clinical practitioners have mixed views whether reading and spelling difficulties should be combined or seen as separate. This study examined the following: (a) if double dissociation between reading and spelling can be identified in a transparent orthography (Finnish) and (b) the cognitive and noncognitive precursors of this phenomenon. Finnish-speaking children (n = 1963) were assessed on reading fluency and spelling in grades 1, 2, 3, and 4. Dissociation groups in reading and spelling were formed based on stable difficulties in grades 1–4. The groups were compared in kindergarten phonological awareness, rapid automatized naming, letter knowledge, home literacy environment, a…

"Ois kiva et se kattois mua ja puhuis" : cochlear implanted learners' experiences of learning English as a foreign language, a case study

2015

Sisäkorvaistutteen (SI) saaneiden lasten määrä kasvaa jatkuvasti ja monet heistä opiskelevat yhtä tai jopa useampaa vierasta kieltä, yleisimmin englantia. Meillä on käsissämme ensimmäinen sukupolvi lapsia ja nuoria, jotka on implantoitu nuorena ja jotka ovat opiskelleet vieraita kieliä SI:n kanssa. Tietooni ei ole tullut, että vieraiden kielten oppimista SI:n kanssa olisi Suomessa vielä tutkittu, joten tämä tutkimus on ainakin ensimmäisten joukossa selvittämässä SI-lasten ja -nuorten kokemuksia englanninoppimisesta. Tutkimukseen osallistui kuusi 10 – 17-vuotiasta sisäkorvaistutteen saanutta lasta. Heitä haastateltiin ja haastattelut analysoitiin sisällönanalyysin keinoin. Tulokset osoittiva…

Effects of the foot evolution on the behaviour of slow-moving landslides

2011

The paper presents a time-dependent 2D numerical model which has been developed with the purpose of highlighting the effects of the slope foot evolution on the behaviour of slow-moving landslides. The model allows to quantitatively analyse how foot mass variations can influence the stability and the movement rates of the landslide. The landslide body is modelled as composed of two rigid blocks sliding on two different planes and interacting through a common boundary, which position is assumed fixed during the analysis. A finite difference approach is used to discretize the time. For each time increment, changes in model parameters are allowed, including variations in shearing resistances, g…
