Prediction of the difficulty level in a standardized reading comprehension test : contributions from cognitive psychology and psychometrics
2013
Esta investigación busca identificar posibles variables predictoras del nivel de dificultad de los ítems de comprensión de lectura utilizados en una prueba psicométrica estandarizada para la admisión a una institución universitaria. Se propusieron varios posibles predictores del nivel de dificultad, a saber: densidad proposicional, negaciones, estructura sintáctica, dificultad del vocabulario, presencia elementos de realce (palabras resaltadas tipográficamente), abstracción del ítem y grado de similitud entre opción correcta y texto relevante para resolver el ítem. Mediante el Modelo Logístico Lineal de Rasgo Latente se encontró que la cantidad de proposiciones, la estructura sintáctica y, …
Online guided self-help to augment standard treatment for people with anorexia nervosa: feasibility, efficacy and process measures
2021
Background: There is mounting evidence on the effectiveness of guided self-help (GSH) interventions to augment, shorten or replace standard care for eating disorders (EDs). However, only few studies have tested the use of GSH for people with anorexia nervosa (AN). Aims: 1) to conduct a systematic review and meta-analysis of GSH in AN, with a focus on clinical outcomes and feasibility; 2) to evaluate the feasibility, acceptability and efficacy of a novel digital GSH intervention for AN (RecoveryMANTRA) tested in addition to treatment as usual (TAU) in the outpatient setting, 3) to assess predictors of drop-out from the RecoveryMANTRA + TAU condition; 4) to establish the role of working allia…
Individual differences in adaptive choice strategies
2003
Abstract Individual differences in compensatory and non-compensatory choice processes remain an unresolved issue for decision process researchers. This study investigates the stability and nature of individual differences in choice processes when individuals adapt to changes in the structure of the choice environment, namely the correlation among the choice attributes. By means of process tracing techniques, between-subjects differences in choice processing (option-based or attribute based) were found to be stable across different tasks. Individuals with higher openness to experience and ability to solve reasoning tasks were found to be more adaptive, that is to switch more promptly their c…
Efectos conductuales y neuroquímicos del consumo de éxtasis y cocaína en ratones adolescentes.
2009
La 3,4-metilendioximetanfetamina (MDMA), una sustancia popularmente conocida como éxtasis, es una droga ilícita consumida habitualmente por adolescentes y adultos jóvenes. Además, el policonsumo es una práctica habitual entre los usuarios de la MDMA, siendo la cocaína una de las drogas más frecuentemente asociadas a esta sustancia. El objetivo del presente trabajo fue evaluar los efectos a corto y largo plazo que se producen tras la administración de la MDMA (5, 10, o 20 mg/kg) sola o en combinación con cocaína (25 mg/kg) en ratones adolescentes. En el estudio sobre el efecto agudo, observamos que ambas drogas administradas individual o simultáneamente incrementan la actividad motora. La do…
The time course of processing handwritten words: An ERP investigation
2021
Available online 25 June 2021. Behavioral studies have shown that the legibility of handwritten script hinders visual word recognition. Furthermore, when compared with printed words, lexical effects (e.g., word-frequency effect) are magnified for less intelligible (difficult) handwriting (Barnhart and Goldinger, 2010; Perea et al., 2016). This boost has been interpreted in terms of greater influence of top-down mechanisms during visual word recognition. In the present experiment, we registered the participants’ ERPs to uncover top-down processing effects on early perceptual encoding. Participants’ behavioral and EEG responses were recorded to high- and low-frequency words that varied in scr…
Task and Ego Goal Orientations across the Youth Sports Experience
2017
Since the late 1980s, Achievement Goal Theory (AGT) has flourished in the competitive sports research across all age groups. One central proposition is the undifferentiated conception of ability exist until approximately 12 years of age. Given the volume of AGT age-specific studies, quantitative analysis of available youth studies allows for examining whether the goal orientations (i.e., task and ego) scores change based on age (i.e., undifferentiated to the differentiated conception of ability). Hence, the purpose of this quantitative based review was to determine whether task and ego orientation values differ based on age. To achieve our objective, we conducted a meta-analysis with 16 stu…
Proprioception but not cardiac interoception is related to the rubber hand illusion
2020
The rubber hand illusion (RHI) is a widely used tool in the study of multisensory integration. It develops as the interaction of temporally consistent visual and tactile input, which can overwrite proprioceptive information. Theoretically, the accuracy of proprioception may influence the proneness to the RHI but this has received little research attention to date. Concerning the role of cardioceptive information, the available empirical evidence is equivocal. The current study aimed to test the impact of proprioceptive and cardioceptive input on the RHI. 60 undergraduate students (32 females) completed sensory tasks assessing proprioceptive accuracy with respect to the angle of the elbow jo…
Clustering Analysis of Questionnaire for Ph.D. studies in Electrical and Information Engineering in Europe
2013
The ELLEIEC ERASMUS thematic network was running from October 2008 to September 2011. This project deals with several aspects linked to Lifelong Learning in Electrical and Information Engineering in Europe. Within this project, Task 4 is dedicated to “Implementation issues across EIE”. The idea of this task was to see how we can, thanks to implementation using Programs available from the European Commission, and associates (ERASMUS, CD, ERASMUS-MUNDUS, ATLANTIS, IP) to emphasize and develop mobility and cross-recognition. Another aspect, strongly connected, was to analyze the existing and possible interactions of Higher Education Institutions and Lifelong Learning. The European consortium o…
Scripted Collaboration and Group‐Based Variations in a Higher Education CSCL Context
2009
Scripting student activities is one way to make Computer‐Supported Collaborative Learning more efficient. This case study examines how scripting guided student group activities and also how different groups interpreted the script; what kinds of roles students adopted and what kinds of differences there were between the groups in terms of their activities. Seven small groups of higher education students participated in the study. According to the findings, scripting enhanced collaboration and ensured that all groups were able to complete the task, but despite the script the groups' activities varied during the task and the script could not guarantee any “high‐level” participation by all stud…
Parent-child communication as a function of parental education, sex of parent and child and situational factors
1987
Parent-child communication was studied in different contexts (home vs laboratory, variation between and within the tasks, dyad vs triad). The subjects were 48 Finnish families with a four-year-old child. The families were divided into euqual groups of lower and higher parental education. The experiments were carried out in two stages: the first in the laboratory setting and the second in the laboratory setting or at home. The videotaped situations consisted of different cooperative tasks. The first result based on global ratings of dyads and triads (initiation/guidance, cooperation, emotionality) and on evaluation of parents’ teaching styles showed only minor differences in interactional me…
