De nuevo sobre la intensificación pragmática : revisión y propuesta
2021
Este artículo presenta una propuesta de caracterización de la intensificación desde una perspectiva pragmática con el objetivo de contribuir al establecimiento de una definición completa, delimitada y unitaria del fenómeno, que permita reconocer y discriminar los usos intensificaciones de otras categorías cercanas. Para ello, se revisan las principales aportaciones previas al estudio del fenómeno: desde las más extendidas, de carácter gramatical y semántico, a las más recientes de naturaleza pragmática.
 Se propone, por un lado, una explicación cognitiva y metarrepresentacional que define la intensificación como el intento lingüístico de un hablante por modificar los supuestos que le a…
A moderate diet restriction during pregnancy alters the levels of endocannabinoids and endocannabinoid-related lipids in the hypothalamus, hippocampu…
2017
Existe para su consulta material suplementario aportado por el editor. Undernutrition during pregnancy has been associated to increased vulnerability to develop metabolic and behavior alterations later in life. The endocannabinoid system might play an important role in these processes. Therefore, we investigated the effects of a moderate maternal calorie-restricted diet on the levels of the endocannabinoid 2-arachidonoyl glycerol (2-AG), arachidonic acid (AA) and the N-acylethanolamines (NAEs) anandamide (AEA), oleoylethanolamide (OEA) and palmitoylethanolamide (PEA) in the brain of newborn rat offspring. We focused on brain structures involved in metabolism, feeding behavior, as well as em…
Polyphenol-Rich Foods in the Mediterranean Diet are Associated with Better Cognitive Function in Elderly Subjects at High Cardiovascular Risk
2012
Brain oxidative processes play a major role in age-related cognitive decline, thus consumption of antioxidant-rich foods might help preserve cognition. Our aim was to assess whether consumption of antioxidant-rich foods in the Mediterranean diet relates to cognitive function in the elderly. In asymptomatic subjects at high cardiovascular risk (n = 447; 52% women; age 55-80 y) enrolled in the PREDIMED study, a primary prevention dietary-intervention trial, we assessed food intake and cardiovascular risk profile, determined apolipoprotein E genotype, and used neuropsychological tests to evaluate cognitive function. We also measured urinary polyphenols as an objective biomarker of intake. Asso…

Mediterranean Diet and Age-Related Cognitive Decline
2015
IMPORTANCE: Oxidative stress and vascular impairment are believed to partly mediate age-related cognitive decline, a strong risk factor for development of dementia. Epidemiologic studies suggest that a Mediterranean diet, an antioxidant-rich cardioprotective dietary pattern, delays cognitive decline, but clinical trial evidence is lacking. OBJECTIVE: To investigate whether a Mediterranean diet supplemented with antioxidant-rich foods influences cognitive function compared with a control diet. DESIGN, SETTING, AND PARTICIPANTS: Parallel-group randomized clinical trial of 447 cognitively healthy volunteers from Barcelona, Spain (233 women [52.1%]; mean age, 66.9 years), at high cardiovascular…
Designing ICTs for Users with Mild Cognitive Impairment: A Usability Study
2020
Background: Research has supported the cost-effectiveness of cognitive training tools enhanced by information and communication technologies (ICT) in several populations, including individuals with mild cognitive impairment (MCI) and age-related cognitive decline. The implementation of ICTs in this population, however, is sometimes challenging to their cognitive and age characteristics. Ultimately, this might compromise the effectiveness of ICT-enhanced therapies in this population. The aim of this study is to test the usability and acceptability of a European project prototype for elderly care, in an attempt to explore the ICT design needs of users with MCI. Methods: Participants were 28 i…
Associative and implicit memory performance as a function of cognitive reserve in elderly adults with and without mild cognitive impairment
2016
AbstractThis study aims to analyze implicit and explicit memory performance as a function of cognitive reserve (CR) in a healthy control group (N = 39) and a mild cognitive impairment (MCI) group (N = 37). Both groups were subdivided into high and low cognitive reserve, and were asked to complete an explicit and implicit associative recognition tasks. The results showed that the control group was able to learn both tasks (η2 = .19, p < .0001), and the high CR group fared better (η2 = .06, p < .05). The MCI sample, conversely, was unable to learn the implicit relationship, and showed very little learning on the explicit association task. Participants diagnosed with MCI showed little pl…

Aspectos del concepto de aprendizaje de las ciencias y el papel de la metacognición
1999
RESUMEN: En este artículo se aborda la perspectiva metacognitiva sobre el aprendizaje de las ciencias, se plantean los roles tanto de estudiantes como de profesores dentro de un modelo didáctico de aprendizaje y se clarifica lo que se debe entender por metacognitivo en el campo de la educación en ciencias.

Motivation and metacognition: more than an interrelation
2001
The aim of this article is to reflect on the possible relation between metacognition and motivation. Some aspects such as causality, locus of control or success expectancy can be conditioned by the metacognitive knowledge of students. We also establish a parallel between the development of metacognition and the characteristics of the kind of motivation in students. We incorporate this parallel with the learning styles that the students can apply in their studies.
