In this work, we carried out a metaanalysis on gender differences in attitudes towards ICT, from a global perspective and exploring four dimensions: affective-emotional attitude, beliefs, self-efficacy, and mixed with each other. Through the collection of 55 studies providing 73 effect sizes based on a total sample of 21,325 working teachers, a negative effect was found, almost null (d=-0.0297) and not statistically significant. These results indicate that female teachers have a more positive attitude towards the educational use of ICT than male teachers. Independently, the dimensions affective-emotional attitude (d=-0.342), beliefs (d= 0.114), and selfefficacy (d= 0.273) produced significant effect sizes, although with small effects. The analysis of moderating variables showed that different moderators intervene significantly in the variability of effect sizes: continental origin of the teachers (emotional and beliefs dimensions); teacher's workplace (dimension self-efficacy); type of publication (emotional dimension) and validity of the instruments (emotional and beliefs dimension). With this meta-analysis, it is possible to take another step towards a better measurement and explanation of the attitudes that teachers have towards the use of new technologies in educational contexts.

Current research indicates that Lesbian, Gay, Bisexual, Transgender, Transsexual, and other LGBT+ people suffer the highest rates of bullying, while other studies suggest that this bullying does not occur based on the victim’s actual sexual orientation or gender identity, but because they do not fit into the traditional gender roles. The aim of the present study was to carry out a meta-analytical study on the prevalence of gender-based bullying against LGBT+ schoolchildren and adolescents in Spain. Methods: The review was carried out following the recommendations of the PRISMA group and allowing us to identify a total of 24 studies. All of these studies were published since 2008, and most of them conducted cross-sectional survey-type research. It was also found that the instrument used to assess bullying varied greatly among studies, resulting in an enormous heterogeneity of research on this topi...

However, the prevalence of sarcopenia may increase due to a range of other factors, such as sleep quality/duration. Therefore, the aim of the study is to conduct a systematic review with meta-analysis to determine the prevalence of sarcopenia in older adults based on their self-reported sleep duration. Methods: Three electronic databases were used—PubMed-Medline, Web of Science, and Cochrane Library. We included studies that measured the prevalence of sarcopenia, divided according to sleep quality and excluded studies (a) involving populations with neuromuscular pathologies, (b) not showing prevalence values (cases/control) on sarcopenia, and (c) not including classificatory models to determine sleep quality. Results: high prevalence values in older adults with both long and short sleep duration were shown. However, prevalence values were higher in those with inadequate sleep (<6–8 h or low efficiency) (OR 0.76; 95% CI (0.70–0.83); Q = 1.44...

Here, we aim to revise the concept of MCI and its subtypes, addressing the problems of classification not only from the psychometric point of view or by using alternative methods, such as latent class analysis, but also considering the absence of normative data. In addition to the well-known influence of certain factors on cognitive function, such as educational level and cultural traits, recent studies highlight the relevance of other factors that may significantly affect the genesis and evolution of MCI: subjective memory complaints, loneliness, social isolation, etc. The present work will contemplate the most relevant attempts to clarify the issue of MCI categorization and classification, combining our own data with that from recent studies which suggest the role of relevant psychosocial factors in MCI.

El contenido de este libro pretende ofrecer una introduccion de caracter general sobre la investigacion cientifica en el ambito de la psicologia, exponiendo la diversidad de estrategias de investigacion existentes en esta area. El objetivo del libro es proporcionar al lector un esquema conceptual que permita el analisis critico de la investigacion psicologica y una adecuada comprension de las aportaciones especificas de las diferentes estrategias de investigacion en los diversos campos de aplicacion en psicologia.

Basic fibroblast growth factor or fibroblast growth factor-2 (FGF2) is an anti-inflammatory, angiogenic, and neurotrophic factor that is expressed in many cell types, including neurons and glial cells. Here, we explored whether subcutaneous administration of FGF2 could have therapeutic effects in the APP 23 transgenic mouse, a model of amyloid pathology. FGF2 treatment attenuated spatial memory deficits, reduced amyloid-β (Aβ) and tau pathologies, decreased inducible nitric oxide synthase expression, and increased the number of astrocytes in the dentate gyrus in APP 23 mice compared with the vehicle-treated controls. The decrease in Aβ deposition was associated with a reduction in the expression of BACE1, the main enzyme responsible for Aβ generation. These results wer...

El objetivo del presente estudio es conocer las alteraciones en l a memoria de trabajo asociadas al proceso de envejecimiento, para poder seguir mejorando la calidad de vida de las personas mayores. La memoria de trabajo es un sistema de capacidad limitada que implica, por una parte, un almacenamiento temporal de cierta informacion y, por otra, la capacidad de ejecucion de una tarea de procesamiento (que requiere, a su vez, atencion, seleccion y manipulacion de determinados estimulos). Dicho sistema tiene importantes implicaciones en el funcionamiento cognit ivo del individuo, pues es utilizado en: razonamiento, calculo, lenguaje, jugar a las cartas, aprender a utilizar el ordenador, encontrar una direccion, etc., siendo uno de los sistemas que mas se ve afectado por el envejecimiento (Craik, 2000; Cr...

Through different subtests, the TAVEC allows verbal learning and episodic memory to be evaluated, an assessment that was carried out on a sample of 382 cognitive healthy Spanish individuals aged 60-90 years old. Unlike the participant's educational level, their age and sex significantly influenced performance in the TAVEC. We provide tables that allow the scaled scores obtained with this test to be adjusted for age and other tables with the relevant adjustments for sex. The normative data obtained in this study will help more precisely interpret the performance of older Spanish adults in the TAVEC, enhancing the utility of this neuropsychological test to evaluate verbal learning and episodic memory in clinical settings and in relation to healthy aging.
