“SmartGlass” Obstacles for Dynamic Inducing of Light Scattering in Vision Research Experiments

2017

We describe a technique that allows control of visual stimuli quality through the use of a setup with a polymer dispersed liquid crystal (PDLC) film positioned in the optical pathway of one or both human eyes. Nowadays, PDLC films allow alteration of the resolution and contrast limits of the transmitted light due to continuous change in the light scattering that is obtained by the application of an AC electrical field. In our experimental setup, the use of a wide-aperture up to area of 20 x 15 cm2 PDLC sheet is combined with a flat-screen PC display or with a modified display emission block without its interference filter unit and with an installed individually controllable colored light-em…

Propiedades psicométricas del cuestionario ActEval sobre la actividad evaluadora del profesorado universitario

2013

This article presents the results of the empirical validation of the questionnaire ActEval (Self-Report on the Evaluation Activity of university teachers). ActEval attempts to identify how important teachers consider a variety of assessment tasks, whether they feel competent, and to what extent they use them in their daily practice, in line with the new competences under the European Higher Education Area. Validation is studied using Non-Metric Multidimensional Scaling (PROXSCAL) and the reliability results show high levels of internal consistency. The data suggest that some items in the questionnaire should be reviewed in order to obtain an effective tool for the analysis of evaluation pra…

Percepciones Organizacionales, Liderazgo y Desempeño en el Trabajo: ¿Están Relacionados?

2011

An in depth review of literature shows that there is a pressing need to holistically understand how and why the organizational leadership process affects organizational behavior in outcomes (e.g. job performance) differently, depending on various national culture settings. One approach may seek to unveil the moderation of cultural values on the relationship between preferred as well as exhibited styles of leadership and behavioral organizational outcomes. An alternative approach may explore how and why cultural values affect the relationship between the quality of leader - subordinate relationships (LMX) and behavioral organizational outcomes differently. Moreover, as we notice a constant g…

Organizational Perceptions, Leadership and Performance in Work Settings: Do they Interrelate?

2011

Una revisión en profundidad de la literatura muestra que hay una importante necesidad de comprender de manera integral cómo y por qué, dependiendo de la cultura nacional, el proceso de liderazgo influye de manera diferente en los resultados del comportamiento organizacional (desempeño en el trabajo, por ejemplo). Una de las perspectivas trata de desvelar el efecto moderador de los valores culturales en la relación entre los estilos de liderazgo preferidos y exhibidos con los resultados del comportamiento organizacional. Un enfoque alternativo explora cómo y por qué los valores culturales influyen diferencialmente en la relación entre la calidad de las relaciones líder-subordinado (LMX) y lo…

Within-student variability in learning experiences, and teachers’ perceptions of students’ task-focus

2016

In order to advance models of educational processes (intraindividual, intensive longitudinal), we propose a model in which we specify state and trait constructs, and an intraindividual variability construct. In our ecological momentary assessment study, we investigated how trait-level and intraindividual variability of students’ learning experiences (intrinsic and extrinsic motivation, task difficulty, effort exertion, help-seeking and competence evaluations) converged with teacher-reported student task-focus. 285 primary school students’ (Years 5 and 6) completed the Learning Experience Questionnaire using handheld computers, on average 13.6 learning episodes during one week (SD = 4.6; Ran…

What factors relate to three profiles of perception of motor competence in young children?

2022

The study aims were to 1) examine profiles of perception of motor competence (PMC) in relation to actual motor competence (AMC), i.e. under-estimators (UEs), realistic estimators (REs) and over-estimators (OEs) and 2) investigate associations between the profiles and selected socioecological factors at the individual, family and environmental levels. PMC (Pictorial Scale of Perceived Movement Skill Competence) and AMC (Test of Gross Motor Development-Third Edition) were administered to a representative sample of children from 37 childcare centres in Finland (n=441;6.2±0.6yrs;52% boys). Socioecological factors were investigated using a parental questionnaire. The three profiles were formed b…

Effect of consumers’ origin on perceived sensory quality, liking and liking drivers: A cross-cultural study on European cheeses

2021

Abstract We aim at studying consumers’ Perceived Sensory Quality (PSQ) concept. We manipulated a priori both familiarity (contrast local vs. foreign cheeses) and quality level (contrast PDO or traditional cheeses vs. their non-PDO and/or industrial counterpart). The study was run in four European countries. Thus, eight cheeses (one PDO or traditional cheese and one non-PDO cheese from each of the four European countries) were assessed by a total of 438 consumers (from 100 to 120 consumers from each region) in terms of PSQ and liking. The cheeses were also described by a trained panel. PSQ depended on both consumers’ and cheeses’ origin. The main finding is that in the three countries with P…

The impact of sugar and fat reduction on perception and liking of biscuits

2014

Abstract Reducing the fat and/or sugar content in biscuits can be a way to improve their nutritional composition. Seventy-nine consumers of biscuits were recruited to study the impact of these reductions on liking and perception. Four categories of products were selected from a wide range of biscuits available at the French market. Three to six variants of each type of biscuit were produced based on reduced content of sugar, fat or both. Consumers tested the samples under laboratory conditions (6 sessions), recording their liking during initial sessions and crispiness, sweetness and fat perception during latter sessions. Sugar-reduced biscuits were perceived as less sweet than standard bisc…

It's Sad but I Like It The Neural Dissociation Between Musical Emotions and Liking in Experts and Laypersons

2016

Emotion-related areas of the brain, such as the medial frontal cortices, amygdala, and striatum, are activated during listening to sad or happy music as well as during listening to pleasurable music. Indeed, in music, like in other arts, sad and happy emotions might co-exist and be distinct from emotions of pleasure or enjoyment. Here we aimed at discerning the neural correlates of sadness or happiness in music as opposed those related to musical enjoyment. We further investigated whether musical expertise modulates the neural activity during affective listening of music. To these aims, 13 musicians and 16 non-musicians brought to the lab their most liked and disliked musical pieces with a …
