La intervención cognitivo-conductual mejora la cognición de los cuidadores de personas con trastorno del espectro autista: estudio piloto
2017
Abstract As postulated by the stress process model, chronically stressed individuals, such as caregivers of people with chronic psychological disorders, have poorer cognitive performance and higher age-related cognitive decline than individuals not exposed to chronic stress. When analysing this topic in caregivers, the majority of research has been conducted in populations in which the care recipient has dementia and/or Alzheimer's disease, while relatively few studies have analysed cognition in caregivers of offspring with autism spectrum disorder (ASD). The main objective of this pilot study was to analyse the effect of a cognitive-behavioural intervention on cognition in caregivers of pe…
Multi-informant evaluation in autism spectrum disorder: a review study.
2020
In order to establish a diagnosis of autism spectrum disorder (ASD), assessment by different informants is required. Sometimes, however, there are certain discrepancies between evaluators. With the aim of shedding light on possible discrepancies between informants, this work includes an updated review of the literature to examine the degree of agreement between different informants regarding the characteristic symptomatology of ASD in children and adolescents (up to 17 years of age). A total of 20 studies were analyzed, in which the levels of correlation between the evaluations carried out by different informants were moderate or low. A large part of the studies included in this review foun…
EFFECTIVENESS OF SOCIAL STORIES IN INTERVENTION IN AUTISTIC SPECTRUM DISORDER: A REVIEW
2019
Social stories, as a technique of psychoeducational intervention, constitute a recurring element in the practice of professionals responsible for intervention with people with autism spectrum disorder (ASD). This work presents a review of the scientific literature of the last decade about the effectiveness of the application of social stories in the intervention in communication and social skills in people with ASD. Twenty-nine empirical studies were selected according to specific criteria, analyzed according to six categories: age of the participants, objective of the intervention, context of application, person applying the intervention, social validity, and comparison with other interven…
Lead Excretion in Spanish Children with Autism Spectrum Disorder
2015
Among epigenetic factors leading to increased prevalence of juvenile neuropsychiatric disorders, including autism spectrum disorder, exposure to metals, such as lead (Pb) have led to conflicting results. The aim of the present study was to determine the levels of Pb in the urine of children with autism spectrum disorder (ASD) compared with typically developing children (TD) age- and sex-matched, and to analyze any association between core symptoms of ASD, special diets, supplements intake or prescription drugs and the concentration of Pb. The study was performed in a group of children with ASD (n = 35, average age 7.4 ± 0.5 years) and TD (n = 34, average age 7.7 ± 0.9 years). Measurement of…
Semantic processing in children with autism spectrum disorder
2021
El presente estudio analizó el procesamiento semántico de un grupo de niños con trastorno del espectro autista (n= 24), con el objetivo principal de averiguar si presentan diferencias en comparación con un grupo de niños con desarrollo típico (n = 24). Para ello, se realizó un análisis del contenido de los ítems del subtest de información del WPPSY-III, estableciendo una serie de categorías en función del tipo de demanda semántica requerida: asociación significante-significado, relación experiencial y conocimiento general. Los resultados obtenidos apoyan la idea de que los niños con autismo realizarían un procesamiento semántico de la información de la misma manera que los niños sin autismo…
Purcell Enhancement and Wavelength Shift of Emitted Light by CsPbI3 Perovskite Nanocrystals Coupled to Hyperbolic Metamaterials
2020
Manipulation of the exciton emission rate in nanocrystals of lead halide perovskites (LHPs) was demonstrated by means of coupling of excitons with a hyperbolic metamaterial (HMM) consisting of alternating thin metal (Ag) and dielectric (LiF) layers. Such a coupling is found to induce an increase of the exciton radiative recombination rate by more than a factor of three due to the Purcell effect when the distance between the quantum emitter and HMM is nominally as small as 10 nm, which coincides well with the results of our theoretical analysis. Besides, an effect of the coupling-induced long wavelength shift of the exciton emission spectrum is detected and modeled. These results can be of i…
MATERNAL EXPOSURE TO STRESSFUL/TRAUMATIC EVENTS AND AUTISM SPECTRUM DISORDERS IN OFFSPRING: PRELIMINARY FINDINGS OF A CASE CONTROL PILOT STUDY.
2023
The correlation between maternal exposure to stressful and traumatic events during pregnancy and autism spectrum disorder (ASD) in offspring has been studied in the literature. Fewer studies, however, have considered the mother's exposure to traumatic events during childhood. This work focuses on maternal exposure to these events in childhood and/or adulthood, relating it to autism spectrum disorder in offspring. A questionnaire was used to assess whether and to what type of event the mothers have been exposed, and to assess eventual peri-traumatic dissociation related to the traumatic event. The mothers involved in this study were recruited at the Child Neuropsychiatry Outpatient Clinic of…
Spatially Resolved Broadband Synchrotron Emission from the Nonthermal Limbs of SN1006
2018
We present ~400ks NuSTAR observations of the northeast (NE) and southwest (SW) non-thermal limbs of the Galactic SNR SN1006. We discovered three sources with X-ray emission detected at >50keV. Two of them are identified as background AGN. We extract the NuSTAR spectra from a few regions along the non-thermal limbs and jointly analyze them with the XMM-Newton spectra and the radio data. The broad-band radio/X-ray spectra can be well described with a synchrotron emission model from a single population of CR electrons with a power law energy distribution and an exponential cutoff. The power law index of the electron particle distribution function (PDF) is ~1.88-1.95 for both the NE and SW l…
Pre-Service Teachers’ Knowledge, Misconceptions and Gaps About Autism Spectrum Disorder
2017
The inclusive education framework and the increase in autism diagnoses have led to an overwhelming challenge for pre-service teachers who need to be qualified to teach all children. To test the quality of their training, the main purpose of this study was to compare 866 pre-service teachers’ knowledge, misconceptions, and gaps about autism in their first and final year at university, using the Autism Knowledge Questionnaire. The results show that fourth-year students obtained higher levels of knowledge and fewer gaps than the first-year students, although they also had more misconceptions. Special education specialists obtained significantly more knowledge and fewer misconceptions than the…
Inclusive didactics and assistive technologies: the experience of a group of special needs teachers
2018
This paper describes the results of an exploratory survey aimed to examine the experience of a group of special needs teachers on the use of ICT in teaching to students with autism spectrum disorder. It is focused on the effectiveness of video modeling as a tool through which to learn (self-learning and imitation) specific skills in the field of personal autonomy. By sharing the thought of Rossi (2012), which has stated that "digital technologies provide to school an extraordinary opportunity to put on the agenda the issue of learning and, together with it, the professionalism of teachers", the authors handed out a questionnaire to a group of special needs teachers of a Comprehensive School…
