An evolutionary perspective on stress responses, damage and repair

2022

Variation in stress responses has been investigated in relation to environmental factors, species ecology, life history and fitness. Moreover, mechanistic studies have unravelled molecular mechanisms of how acute and chronic stress responses cause physiological impacts (‘damage’), and how this damage can be repaired. However, it is not yet understood how the fitness effects of damage and repair influence stress response evolution. Here we study the evolution of hormone levels as a function of stressor occurrence, damage and the efficiency of repair. We hypothesise that the evolution of stress responses depends on the fitness consequences of damage and the ability to repair that damage. To o…

Different Endurance Exercise Modalities, Different Affective Response: A Within-Subject Study

2021

Affect experienced during an exercise session is supposed to predict future exercise behavior. However, empirical evidence reveals high variability in affective response to different exercise modalities. Thus, the purpose of the present study was to compare acute affective response and its variation during three different endurance exercise modalities: (a) moderate-intensity continuous exercise (MICE), (b) vigorous-intensity continuous exercise (VICE), and (c) high-intensity interval exercise (HIIE). Using the dual-mode theory as a theoretical framework, cognitive and interoceptive factors were considered as potential predictors of in-task affective response. In a within-subject design, 40 …

Changes in students’ understanding of and visual attention on digitally represented graphs across two domains in higher education : a postreplication…

2020

Domain-specific understanding of digitally represented graphs is necessary for successful learning within and across domains in higher education. Two recent studies conducted a cross-sectional analysis of graph understanding in different contexts (physics and finance), task concepts, and question types among students of physics, psychology, and economics. However, neither changes in graph processing nor changes in test scores over the course of one semester have been sufficiently researched so far. This eye-tracking replication study with a pretest–posttest design examines and contrasts changes in physics and economics students’ understanding of linear physics and finance graphs. It analyze…

Wider Letter-Spacing Facilitates Word Processing but Impairs Reading Rates of Fast Readers

2020

Previous reports of improved oral reading performance for dyslexic children but not for regular readers when between-letter spacing was enlarged led to the proposal of a dyslexia-specific deficit in visual crowding. However, it is in this context also critical to understand how letter spacing affects visual word recognition and reading in unimpaired readers. Adopting an individual differences approach, the present study, accordingly, examined whether wider letter spacing improves reading performance also for non-impaired adults during silent reading and whether there is an association between letter spacing and crowding sensitivity. We report eye movement data of 24 German students who sile…

Recognition of briefly presented familiar and unfamiliar faces

2009

Early processing stages in the perception of familiar and unfamiliar faces were studied in four experiments by varying the type of available facial information in a four alternative forced choice recognition task. Both reaction time and recognition accuracy served as dependent measures. The observed data revealed an asymmetry in processing familiar and unfamiliar faces. A markedly weak inversion effect and strong blurring effect suggest a limited usage of spatial relations within early processing stages of unfamiliar faces. Recognition performance for whole familiar faces did not deteriorate due to blurring or the presentation of isolated internal features, suggesting a low level of represe…

The perceptions of parents of children with cancer about changes in family relations

2012

Objetivos: conocer cómo perciben los padres los cambios producidos en las relaciones familiares debidos a un cáncer pediátrico. Método: Se ha utilizado una metodología de investigación grupal (grupos de autoayuda) y cualitativa (análisis del discurso de los participantes en las sesiones grupales). La muestra la constituyen 22 madres/padres cuyos hijos hace más de dos años que han contraído la enfermedad. Las sesiones grupales se realizaron en la sede de ASPANION (Asociación de padres de niños oncológicos de la Comunidad Valenciana) en Valencia. Resultados: Se constata cómo la enfermedad cambia las relaciones: – Con la pareja: redistribución de roles, diferentes formas de reaccionar y de asu…

Playing Roles in Work and Family: Effects of Work/Family Conflicts on Job and Life Satisfaction Among Junior High School Teachers

2021

Junior high school teachers play an essential role in education. How to relieve the worries of teachers, that is, the pressure they face in the fields of work and family, has increasingly become an urgent problem. Based on the COR theory, this study aims to investigate the effects of two types of work/family conflicts (i.e., work-family conflict and family-work conflict) on teachers’ job and life satisfaction. We adopted a handy sample method and collected a total of 560 junior high school teachers data. The results confirmed that both work-family and family-work conflicts are not significantly related to junior high school teachers’ job satisfaction and life satisfaction directly. However,…

A CUDA-based implementation of an improved SPH method on GPU

2021

We present a CUDA-based parallel implementation on GPU architecture of a modified version of the Smoothed Particle Hydrodynamics (SPH) method. This modified formulation exploits a strategy based on the Taylor series expansion, which simultaneously improves the approximation of a function and its derivatives with respect to the standard formulation. The improvement in accuracy comes at the cost of an additional computational effort. The computational demand becomes increasingly crucial as problem size increases but can be addressed by employing fast summations in a parallel computational scheme. The experimental analysis showed that our parallel implementation significantly reduces the runti…

Un estudio piloto sobre el efecto diferencial de la fatiga por conducción en personas mayores

2011

Hay indicios de que la fatiga, uno de los principales efectos de la conducción prolongada, es más notable en mayores. El presente artículo recoge un estudio sobre el efecto de la conducción prolongada utilizando un simulador, en un grupo de sujetos mayores de 55 años. Los sujetos fueron evaluados médica y psicológicamente antes y después de la prueba de conducción. Se aplicaron las pruebas médicas de tensión arterial, pulso y saturación de oxígeno en sangre y como prueba psicológica, el Driver-Test. Resultados preliminares indican que existe una disminución del rendimiento después de conducir, afectando especialmente a la capacidad de toma de decisiones. Some evidences show that fatigue, th…
