¿Cuátna prátcica letcora hace fatla praa que poadmos leer palbraas con lertas trasnpuetsas?
2020
Las letras son estímulos visuales especiales. Inmersas en palabras, nos cuesta mucho distinguir “cedro” de “cerdo”, lo cual se conoce como efecto de transposición. Este efecto sucede en menor grado con secuencias de dígitos o símbolos. ¿Cuándo comienzan las letras a tener ese estatus especial? En un experimento reciente de nuestro laboratorio demostramos que seis días de práctica intensiva no son suficientes, pero ya permiten vislumbrar los inicios de un procesamiento especial de las letras.
¿Podemos agilizar la lectura en aprendices de chino?
2018
Una de las dificultades que conlleva el aprendizaje del chino es que las palabras escritas no están delimitadas. Una estrategia para minimizar dicha dificultad es añadir espacios entre palabras, pero ello genera un patrón alterado de los movimientos oculares que reduce la eficiencia del procesamiento visual. Una mejor opción es colorear alternadamente las palabras de un texto. Esta manipulación produce tiempos de lectura más rápidos en lectores principiantes de chino y ayuda en textos con palabras poco familiares en lectores adultos. Por tanto, la coloración alternada es una buena opción para agilizar el aprendizaje lector en chino.
Los colores como claves perceptivas durante la lectura
2015
En español, como en muchas otras ortografías, las palabras escritas están diferenciadas unas de otras mediante la inserción de espacios. El hecho de que haya lenguas que no utilizan espacios, y que añadirlos no mejore la lectura en dichas lenguas (v.g., en thai), relativiza la importancia de los espacios entre palabras. Experimentos recientes en nuestro laboratorio han mostrado que la segmentación perceptiva de las palabras puede conseguirse fácilmente alternando el color de las mismas, sin necesidad de espacios. Ello lleva a re-examinar el papel de los colores en el aprendizaje de la lectura.
Buscando las claves de la lectura en personas sordas
2016
En este trabajo examinamos los procesos de reconocimiento visual de palabras en una población que muestra generalmente un bajo nivel lector: las personas sordas prelocutivas. Si bien investigaciones recientes han mostrado que las personas sordas hacen uso efectivo de la información proveniente de la forma visual de las palabras, no lo hacen de su sonido. Por tanto, en la intervención educativa, sería conveniente que los profesionales que trabajaran con personas sordas emplearan procedimientos que les permitieran desarrollar una correspondencia más estable entre las letras y sus sonidos.
System identification via optimised wavelet-based neural networks
2003
Nonlinear system identification by means of wavelet-based neural networks (WBNNs) is presented. An iterative method is proposed, based on a way of combining genetic algorithms (GAs) and least-square techniques with the aim of avoiding redundancy in the representation of the function. GAs are used for optimal selection of the structure of the WBNN and the parameters of the transfer function of its neurones. Least-square techniques are used to update the weights of the net. The basic criterion of the method is the addition of a new neurone, at a generic step, to the already constructed WBNN so that no modification to the parameters of its neurones is required. Simulation experiments and compa…
Techniques culinaires et confort en bouche chez la personne âgée
2020
Culinary processes and food comfortability in an older population Aging is often accompanied by oral impairments, including the loss of teeth and a decline in saliva flow. These changes can lead older people to avoid the consumption of foods that are difficult to chew such as meat. This may consequently increase the risk of sarcopenia (loss of muscle mass, strength and performance) as well as the risk of protein-energy undernutrition in this population. In order to compensate the decline in oral health observed in older individual and to maintain meat consumption, we assessed the impact of four culinary processes (cooking bag, tenderizer, marinade and low-temperature cooking) on the percept…
the role of antidepressant treatments on cognitive deficits: a review of recent literature
2011
Objective: Nowadays, the interaction between cognition and emotions during a depressive disorder in an area of interest in the scientific literature. Patients with major depressive disorder (MDD) usually show alterations in various cognitive functions: attention, working memory, mental processing speed, executive functions. Clinical observation of the effects of cognitive deficits on quality of life in patients with MDD, in euthymic and relapse phases, needs a review of recent scientific literature on the impact of antidepressant treatment as a protective factor of the improvement of cognitive performances. Methods: Electronic PubMed and PsycInfo searches were conducted to identify research…
Identifying Oscillatory Hyperconnectivity and Hypoconnectivity Networks in Major Depression Using Coupled Tensor Decomposition
2021
AbstractPrevious researches demonstrate that major depression disorder (MDD) is associated with widespread network dysconnectivity, and the dynamics of functional connectivity networks are important to delineate the neural mechanisms of MDD. Cortical electroencephalography (EEG) oscillations act as coordinators to connect different brain regions, and various assemblies of oscillations can form different networks to support different cognitive tasks. Studies have demonstrated that the dysconnectivity of EEG oscillatory networks is related with MDD. In this study, we investigated the oscillatory hyperconnectivity and hypoconnectivity networks in MDD under a naturalistic and continuous stimuli…
Change in body image among depressed adult outpatients after a dance movement therapy group treatment
2018
Abstract This study reports on the body image of depressed psychiatric outpatients, and the impact thereon of a dance movement therapy (DMT) group. Body image is perceived as a tri-partite construct consisting of image-properties, body-self, and body memory. Depressed patients in an outpatient mental health service participated in a DMT group treatment consisting of twelve 90-min long sessions in groups of 4–7 patients. Patients (N = 18) responded to a structured Body Image Assessment (BIA) before and after the treatment. Initially, the depressed patients’ body image was characterized by fragmentation, distortions, and shallowness of body awareness. The DMT group treatment aimed to offer th…
Me, osteogenesis imperfecta, and my classmates in physical education lessons: a case study of embodied pedagogy in action
2017
Pupils with disabilities have been found to experience a narrower physical education curriculum and participate less frequently than pupils without disabilities. A lack of knowledge, skills, relevant experiences and confidence amongst physical education (PE) teachers has been said to contribute to these differential educational experiences. This article adds to the paucity of research that analyses the PE experiences of pupils with disabilities while, at the same time, evaluating embodied pedagogy as a tool for better preparing PE teachers for their role as inclusive educators. Specifically, the article aims to: (1) explore the PE experiences of a university student named Violeta who lives …
