Didactic transposition of the biodiversity concept. A study of Spanish high-school textbooks
2021
Este trabajo estudia la presencia y complejidad en el tratamiento del concepto de diversidad biológica en libros de texto de educación secundaria, tanto de la obligatoria (ESO) como del bachillerato de España. Se recopilaron trabajos científicos de la «comunidad de expertos» con el objetivo de definir el ámbito conceptual de la biodiversidad, que actúa de vigilante epistemológico en el proceso de transposición didáctica. Los resultados mostraron una multiplicidad de definiciones de la biodiversidad en libros de texto, con un fuerte predominio de reducción a la idea de número de especies (riqueza), lo que pone en evidencia su desactualización. A la luz de este estudio, el listado de contenid…
Use of Caffeine for Cognitive Enhancement
2015
Abstract Pharmacological cognitive enhancement (CE) refers to the use of divergent psychoactive substances with the purpose of enhancing one's own cognition (e.g., increasing vigilance, concentration, memory). The group of substances for CE includes divergent over-the-counter drugs. Caffeine-containing products such as coffee, caffeinated drinks, and caffeine tablets are integral part of this group of substances. Furthermore, prescription drugs as well as illicit drugs belong to this group of CE substances (e.g., [psycho-]stimulants, modafinil). The use of caffeine in normal healthy subjects has very limited procognitive effects. However, there are few procognitive effects in healthy but sl…
Source unreliability decreases but does not cancel the impact of social information on metacognitive evaluations
2015
International audience; Through metacognitive evaluations, individuals assess their own cognitive operations with respect to their current goals. We have previously shown that non-verbal social cues spontaneously influence these evaluations, even when the cues are unreliable. Here, we explore whether a belief about the reliability of the source can modulate this form of social impact. Participants performed a two-alternative forced choice task that varied in difficulty. The task was followed by a video of a person who was presented as being either competent or incompetent at performing the task. That person provided random feedback to the participant through facial expressions indicating ag…
Relaciones entre neurocognición, procesamiento emocional y funcionamiento social en la esquizofrenia
2017
Resumen: En la esquizofrenia se presentan una serie de déficits cognitivos que han hecho que la investigación y la práctica profesional actual se centren en el estudio de la neurocognición y la cognición social. Estos déficits tienen importantes implicaciones en el funcionamiento social. El objetivo del presente trabajo es analizar la relaciones entre neurocognición, cognición social, evaluada con tareas de reconocimiento de la emoción, y funcionamiento social. Sesenta personas con diagnóstico de esquizofrenia han formado la muestra y las áreas evaluadas han sido: funcionamiento ejecutivo y flexibilidad cognitiva, atención y vigilancia, memoria, velocidad de procesamiento, identificación y …
Fatigue while driving in a car simulator : effects on vigilance performance and autonomic skin conductance
2010
In this vigilance research the effect of fatigue on driver’s voluntary reaction times (RT) and autonomic skin conductance (SC) was studied. Participants (n=17) drove approximately 3 hours in a simulator responding simultaneously on a peripheral visual vigilance task (PVVT). RTs were classified into 5 quintiles according to their latency. Also misses and misclassifications were explored. Results indicated that RTs increased linearly over time. SC amplitudes differed significantly between RT quintiles. Vigilance performance was the best when arousals were frequent but their magnitude remained relatively low. Frequent and high amplitude arousals in turn were associated with the worst performan…
Sport participation and vigilance in children: Influence of different sport expertise
2018
PURPOSE: The present study aimed to investigate the relationship between different types of sport expertise (externally-paced vs. self-paced sports) and vigilance performance in children by evaluating the cardiovascular fitness level of the participants. METHODS: Three groups of children (11.0 ± 0.2 years) differentiated in terms of their regular sport participation (football players, n = 20; track and field athletes, n = 20; non-athletic controls, n = 20) took part in the study. In one session, participants performed the Leger Multi-stage fitness test to estimate their aerobic fitness level. In another session, participants completed the Psychomotor Vigilance Task (PVT) to evaluate their v…
Decision-making Styles in Adolescent Offenders and Non-offenders: Effects of Emotional Intelligence and Empathy
2021
The literature indicates that adolescents with delinquent behavior have greater difficulty making rational decisions and show lower emotional intelligence and empathy. Decision-making is a set of complex processes associated with neurobiological, cognitive, emotional, and social factors which help regulate and guide behavior, which could be influenced by emotional intelligence and empathy. A comparative, correlational, and predictive study was conducted to analyze relationships and influence of emotional intelligence and empathy in decision-making styles in adolescent offenders and non-offenders. 808 Colombian adolescents between 14 and 18 years of age participated (50p offenders). The resu…
