Social Cognition in Children with High-Functioning Autism Spectrum Disorder and Attention-Deficit/Hyperactivity Disorder. Associations with Executive…
2017
Autism spectrum disorder (ASD) and attention deficit hyperactivity disorder (ADHD) are neurodevelopmental disorders characterized by social impairments. The first objective of this study was to analyze social cognition deficits of children with ADHD, high-functioning ASD (HFASD), and typical development (TD) in their performance on explicit and applied measures of theory of mind (ToM). The second objective was to investigate the relationships between executive functions and social cognition in HFASD and ADHD. One hundred and twenty-six 7- to 11-year old children, 52 with HFASD, 35 with ADHD, and 39 with TD, performed the NEPSY-II social perception subtests. Parents estimated their children’…
DIF in the Spanish Version of the Verbal Selective Reminding Test Using Samples From Hispanics in the United States, Mexicans, and Spaniards
2019
Before a test can be used in the target population, it is necessary to demonstrate that there is measurement equivalence. One way to do this is by studying differential item functioning. Objective: In this study, we used the Mantel-Haenszel procedure and logistic regression to analyze DIF in the Spanish version of the Verbal Selective Reminding Test between Spaniards, Mexicans and Hispanics in the United States. Method: Three balanced samples, matched by age, education and sex, were studied: Spaniards, Mexicans and Hispanics (616 healthy participants from Spain (n = 211), Mexico (n = 201) and the United States (n = 205). A six-trial version of the Spanish version of the Verbal Selective Rem…
Investigating the professional agency of secondary school English teachers in South Korea
2020
This qualitative study examines the professional agency of secondary English teachers in Midwestern South Korea. Specifically, it investigates how secondary English teachers in South Korea understand their professional agency and what mediates their professional agency. The ecological approach in this study recognises that agency encompasses both individual and environmental dimensions and is formed through the constant interplay between the individual and the environment. The dataset for this study comprises 15 semi-structured interviews with secondary English teachers in South Korea. The thematic analysis highlights a significant gap between Korean English teachers’ espoused agency and re…
Adolescents' perception of scientific inquiry in nature : a drawing analysis
2019
This study was carried out to determine adolescents’ perception of scientific inquiry (SI) in nature and the effect of a science camp on those perceptions. Eleven science campers (14 to 16 years old) participated in this research during a science camp. Pre- and post-test included open questions and drawing tasks. The campers’ drawings were analyzed to assess their out-of-school perceptions related to SI. The aim was to clarify what phases and factors the campers associated with SI in nature, and how their perceptions differ after participating at a science camp. The findings suggest that the phases of SI were well known before the camp, but minor developments in campers’ perceptions of the …
Marcatge posicional i prominència en el vocalisme àton
2008
It has long been noticed that more perceptible elements tend to associate to positions that are structurally stronger to the end that several prominent features converge in the same site; and vice versa: elements of low perceptibility prototypically associate to less prominent positions ("positional markedness"). The main aim of this paper is to present the effects of positional markedness in the a-tonic vowel system of Catalan through the analysis of two cases that have not been studied in depth, i.e. the occurrence of different epenthetic vowels according to the position in which they appear in Alghero and western Catalan, and the presence of different patterns of vowel reduction in weste…
Is it me or the music? : Stress reduction and the role of regulation strategies and music
2019
Music is a common resource for the regulation of emotions, moods, and stress. This study aimed at determining the individual and relative impact on stress reduction of two of the main factors involved in musical affect regulation: regulation strategies and music itself. The current study took place in an experimental setting and followed a factorial within-subjects design. First, the participants ( n = 34) filled in an online survey where they identified their self-perceived “adequate”/“inadequate” music examples for the purpose of reducing stress and self-perceived “adequate”/“inadequate” strategies for the same purpose. In the lab they went through a stress induction procedure and then w…
Professional Competences of Music Therapists Working in Post-stroke Rehabilitation
2012
The aim of this qualitative study is to gain more insight into the skills and knowledge that music therapists feel they need, in order to work successfully with people who have had an acute stroke. For this purpose, six music therapists were interviewed about their own particular specialist education. Another interview topic for them was to recount their subjective experiences of poststroke rehabilitation work in hospitals and health care units during the course of two projects that they participated in. The first was a project that specifically used music listening during acute stroke rehabilitation; and the second was a project, which used more active music therapy techniques, like drummi…
Music May Reduce Loneliness and Act as Social Surrogate for a Friend: Evidence from an Experimental Listening Study
2020
After losing a close other, individuals usually confide in an empathic friend to receive comfort and they seem to have a heightened desire for mood-congruent, consoling music. Hence, it has been proposed that affect-congruent music acts as a social surrogate for an empathic friend. Thus, we hypothesized that listening to comforting music, as a response to a social loss experience, provides a sense of empathic company as indicated by reduced loneliness and heightened empathy. We further predicted that distracting music would have a stronger impact on the listeners’ mood in comparison to comforting pieces. To test these assumptions, an experiment with two factors was designed: (1) Sadness wa…
Mismatch negativity (MMN) in freely-moving rats with several experimental controls.
2014
Mismatch negativity (MMN) is a scalp-recorded electrical potential that occurs in humans in response to an auditory stimulus that defies previously established patterns of regularity. MMN amplitude is reduced in people with schizophrenia. In this study, we aimed to develop a robust and replicable rat model of MMN, as a platform for a more thorough understanding of the neurobiology underlying MMN. One of the major concerns for animal models of MMN is whether the rodent brain is capable of producing a human-like MMN, which is not a consequence of neural adaptation to repetitive stimuli. We therefore tested several methods that have been used to control for adaptation and differential exogenou…
Modulation of the Endocannabinoids N-Arachidonoylethanolamine (AEA) and 2-Arachidonoylglycerol (2-AG) on Executive Functions in Human.
2013
Animal studies point to an implication of the endocannabinoid system on executive functions. In humans, several studies have suggested an association between acute or chronic use of exogenous cannabinoids (Δ9-tetrahydrocannabinol) and executive impairments. However, to date, no published reports establish the relationship between endocannabinoids, as biomarkers of the cannabinoid neurotransmission system, and executive functioning in humans. The aim of the present study was to explore the association between circulating levels of plasma endocannabinoids N-arachidonoylethanolamine (AEA) and 2-Arachidonoylglycerol (2-AG) and executive functions (decision making, response inhibition and cognit…
