Conductas de aprendizaje en niños con trastorno del espectro autista con y sin comorbilidad con déficit de atención e hiperactividad
2018
La literatura ha explorado los problemas en el aprendizaje que presentan los niños con trastorno del espectro autista (TEA), pero apenas se ha analizado el impacto de la comorbilidad con déficit de atención e hiperactividad (TDAH) sobre el aprendizaje en niños con TEA. Objetivos. 1) Analizar las diferencias en la conducta de aprendizaje de niños con TEA con y sin comorbilidad con TDAH y niños con desarrollo típico (TD); 2) Investigar la asociación entre diferentes dominios de conductas de aprendizaje y problemas conductuales y emocionales, en niños con TEA y niños con TEA+TDAH. Método. Participaron 87 niños (30 con diagnóstico de TEA de alto funcionamiento, 22 con TEA+TDAH y 36 con TD entre…
Knowledge Sharing Among Tourists via Social Media: A Comparison Between Facebook and TripAdvisor
2016
This paper examines tourists' knowledge sharing behavior in social media. Based on social capital theory, we aim to examine the effects of three dimensions of social capital—structural (social interaction ties), cognitive (shared vision) and relational (trust)—for two different types of social media: Facebook and TripAdvisor. We propose a structural model that connects an antecedent (homophily) and a consequence (knowledge sharing through posting) of these main dimensions of social capital. An online survey is conducted with 1200 Spanish consumers. Based on the full sample, our structural equation modeling supports most of the hypothesized paths, while trust does not affect either social in…
Expert pianists’ practice perspectives: A production and listening study
2021
The purpose of this study was to investigate how professional pianists practice music for a concert, and whether their individual cognitive orientations in such practice processes can be identified accurately from the resulting performances. In Study I, four pianists, previously found to be skilled music memorizers, practiced and performed a short piece by André Jolivet over the course of two weeks, during which their practice strategies were studied using semi-structured interviews, and analyses of practice diaries, practice activities, and eye-movement data. The results indicate that the pianists used similar basic strategies but had different cognitive orientations, here called “practic…
The influence of body discourses on adolescents’ (non)participation in physical activity
2016
ABSTRACTDrawing on semi-structured interviews with older adolescents, this article examines how healthism, ideal body discourses and performative body discourses influence their (non)participation in physical activity (PA) and their identity construction concerning exercise, sport and physical education. We illustrate that body transformation through PA, and related slim body desire and the fear of masculinised female bodies, affect adolescents’ decisions to engage in or drop out of sport. Also, a non-hegemonic body shape combined with a display of low physical competence triggers classmate and teachers’ rejection and marginalisation, affecting adolescents’ construction of embodied identiti…
Reciprocal relations between autonomous motivation from self-determination theory and social cognition constructs from the theory of planned behavior…
2020
Abstract Objectives The present study examined reciprocal relations between autonomous motivation from self-determination theory (SDT) and constructs from the theory of planned behavior (TPB) in a sport injury context. Methods The study adopted a three-wave longitudinal cross-lagged panel design. Physical education students in China (N = 4414; Mage = 14.42, SD = 1.75) completed self-report measures of autonomous motivation, attitude, subjective norm, and perceived behavioral control with respect to sport injury prevention at baseline (T1) and at two follow-up occasions one (T2) and three (T3) months later. Proposed reciprocal relations between autonomous motivation and the TPB constructs co…
ERP correlates of masked affective priming with emoticons
2013
Emoticons seem to enrich computer-mediated communication by improving enjoyment, perceived richness and usefulness of information (Huang, Yen, & Zhang, 2008). Despite their extensive use over the last decades, the way emoticons affect subsequent emotional/cognitive processing is not fully understood. Here we conducted a masked priming experiment that explored the time course of the masked affective priming effect while recording event-related potentials. Type of prime (emoticon vs. word) and prime valence (positive vs. negative) were manipulated to assess their influence in the processing of positive/negative target words. Results showed a masked affective priming effect in early (N2) and l…
Assessment of learning strategies with the ACRA and the Brief-ACRA scales: Competitive models, measurement invariance, and prediction of academic ach…
2021
Abstract Learning strategies have been widely studied, and they have been related to academic achievement in several studies. Among the measurement instruments developed, the 44-item version of the Learning Strategies Scale (ACRA) is, by far, one of the most widely used questionnaires in the Spanish speaking context. This instrument has been recently shortened to a 17-item version. Neither the 44-item nor the 17-item version have been tested in the Dominican Republic. The aim of this study is to study the psychometric properties of the 44-item and 17-item versions of the ACRA. Participants were 1712 Dominican secondary school students. Both structures of the ACRA were tested via CFA; alpha …
Optimizing Query Perturbations to Enhance Shape Retrieval
2020
3D Shape retrieval algorithms use shape descriptors to identify shapes in a database that are the most similar to a given key shape, called the query. Many shape descriptors are known but none is perfect. Therefore, the common approach in building 3D Shape retrieval tools is to combine several descriptors with some fusion rule. This article proposes an orthogonal approach. The query is improved with a Genetic Algorithm. The latter makes evolve a population of perturbed copies of the query, called clones. The best clone is the closest to its closest shapes in the database, for a given shape descriptor. Experimental results show that improving the query also improves the precision and complet…
Dynamic Functional Connectivity Captures Individuals’ Unique Brain Signatures
2020
Recent neuroimaging evidence suggest that there exists a unique individual-specific functional connectivity (FC) pattern consistent across tasks. The objective of our study is to utilize FC patterns to identify an individual using a supervised machine learning approach. To this end, we use two previously published data sets that comprises resting-state and task-based fMRI responses. We use static FC measures as input to a linear classifier to evaluate its performance. We additionally extend this analysis to capture dynamic FC using two approaches: the common sliding window approach and the more recent phase synchrony-based measure. We found that the classification models using dynamic FC pa…
Exploring Design Cognition in Voice-Driven Sound Sketching and Synthesis
2021
Conceptual design and communication of sonic ideas are critical, and still unresolved aspects of current sound design practices, especially when teamwork is involved. Design cognition studies in the visual domain represent a valuable resource to look at, to better comprehend the reasoning of designers when they approach a sound-based project. A design exercise involving a team of professional sound designers is analyzed, and discussed in the framework of the Function-Behavior-Structure ontology of design. The use of embodied sound representations of concepts fosters team-building and a more effective communication, in terms of shared mental models.
