Does Linguistic Analysis Confirm the Validity of Facilitated Communication?
2016
Facilitated communication (FC) has been interpreted as an ideomotor phenomenon, in which one person physically supports another person’s hand and unconsciously affects the content of the writing. Despite the strong experimental evidence against the authenticity of FC output, several studies claim to support its validity based on idiosyncrasies found in the texts produced. A review of these studies showed that, because of the logical circularity of the reasoning proposed in the studies, no decisive evidence that validated FC was presented. In addition, the idiosyncrasies found were better explained as by-products of the unusual writing process itself. Finally, the studies did not fulfill th…
Adaptive inputs in an interface for people with Dyskinetic Cerebral Palsy: Learning and usability
2016
This study concerns the difficulty in accessing computers faced by people with Dyskinetic Cerebral Palsy (DCP). Thus diminishing their opportunities to communicate or learn. This population usually needs an alternative input human-computer interface (HCI). The paper presents an alternative multimodal HCI that incorporates a head-mounted interface and superficial electromyography sensors (sEMG). The aim of the study is to assess the usability and the suitability of these two HCI devices. Six non-disabled subjects and ten subjects with DCP participated in the iterative process in which each test follows an improvement of an input. The results indicated that for both systems, the improvements …
UnipaBCI a novel general software framework for brain computer interface
2017
The increasing interest in Brain Computer Interface (BCI) requires new fast, reliable and scalable frameworks that can be used by researchers to develop BCI based high performance applications in efficient and fast ways. In this paper is presented "UnipaBCI", a general software framework for BCI applications based on electroencephalogra-phy (EEG) that can fulfill these new needs. A visual evoked potentials (VEP) application has also been developed using the proposed framework in order to test the modular architecture and the overall performance. Different types of users (beginners and experts in BCI) have been involved during the "UnipaBCI" experimental test and they have exhibited good and…
Augmentative Alternative Communication using Eyelid Movement Remote Detection by Speckle Patterns Tracking System for Amyotrophic Lateral Sclerosis D…
2017
The implementation of augmentative alternative communication optical device for ALS speech problem is presented. The sensor is based on temporal tracking of back-reflected secondary speckle patterns generated when illuminating an eyelid with a laser.
Inflectional speaker-role classifiers in Weining Ahmao
2008
Abstract This paper is the first of two (see references) aiming to bring to the attention of pragmaticians an idiosyncratic classifier system that encodes speaker-roles along the lines of gender and age. Isolating (analytic) languages are known for their scarcity of word forms and for their under-specification of grammatical categories. Analytic languages in East and Southeast Asian involve classifiers – a word category without counterpart in most languages of the inflectional type – to attenuate some of the vagueness in the nominal realm. Similar to other parts of speech, the classifier generally constitutes a one-form word category with occasional sandhi-derivations. Weining Ahmao, a Miao…
Rett syndrome and eye-tracking technology: A brief review
2019
Introduction: Rett Syndrome is a severe, genetically based neurodevelopment disorder caused mostlyby mutations in the MECP2 gene on the X chromosome. One of the supportive criteria for the diagnosis of this syndrome is intense eye gaze with preferential eye fixation on social stimuli and especially on people’s eyes. This pattern of preferential looking has generally been considered a way to make requests and communicate. Materials and methods: In this review we have collected the studies on the use of eye-tracking technology with subjects with Rett Syndrome. The combination of keywords “Rett Syndrome” and “Eye Tracking” was used in a Medline literature search. In order to be included in thi…
Intervención terapéutica y coordinación familiar en los inicios comunicativos de un caso de atención temprana
2020
En este estudio de caso se aborda la intervención realizada en un centro de diagnóstico y atención temprana, a una alumna de dos años con hemiparesia lateral izquierda y dificultades en la manipulación y comunicación. Aplicando a lo largo de cuatro meses el sistema de Comunicación Total de Benson Schaeffer con el apoyo del método TEACCH, se pretende superar las graves limitaciones comunicativas de la alumna. El procedimiento metodológico utilizado es mixto y las técnicas de investigación empleadas son la aplicación de un test estandarizado, la entrevista, los registros de observación y el análisis documental. A partir del test cumplimentado por la madre que establece la evaluación inicial d…
Authorship in Facilitated Communication: An Analysis of 11 Cases
2014
Abstract. We studied the authorship of messages produced through facilitated communication (FC) for all users of FC in two comprehensive schools in a small city in Finland. The participants were 11 children with intellectual disabilities, including autism, all having used FC from 1 to 3 years. The test conditions involved open and blind information-passing tasks in which the participants were directed to write down the contents of written or pictorial stimuli. The results failed to validate FC as a method of communication for any participant or facilitator. An analysis of the messages produced under the FC condition revealed a large degree of facilitator influence on the content of the mess…
AUGMENTATIVE AND ALTERNATIVE COMMUNICATION (AAC) IN NEURODEVELOPMENTAL DISORDERS: A MINIREVIEW
2018
Children with neurodevelopmental disorders such as Autism Spectrum Disorders (ASD), cerebral palsy or severe motor speech disorders may beneficiate of augmentative and alternative communication (AAC) systems that may improve the developing language and the communication abilities. The term AAC tend to include each form of communication supplementing or replacing the natural speech production.
