La teoría de Piaget sobre el desarrollo del conocimiento espacial

Resumen

Este artículo presenta un resumen de la teoría de Piaget y sus colaboradores sobre el conocimiento del espacio. En primer lugar se analizan los aspectos principales de la teoría del desarrollo de las nociones espaciales en relación con el desarrollo cognitivo; se continúa con la descripción de los tipos de experimentos utilizados para el estudio del espacio topológico, espacio proyectivo y espacio euclidiano; se concluye poniendo de manifiesto la relevancia del trabajo piagetiano sobre las posteriores investigaciones acerca de la cognición espacial.     

The concept of love in a Spanish representative sample

The model of romantic love and the acceptance of related myths have been granted wide relevance in our context. It has also been suggested that the concept of love can play a role in the origin and maintenance of gender violence. As an initial step towards researching this relationship, the objective of this article is to study the prevailing concept of love in the Spanish population, as well as to analyze any differences that gender and age may introduce in this conception. A reduced version of the Love Attitudes Scale was administered to a representative sample of 1,351 people. Results show that both men and women widely accept the love styles Eros, Agape, Storge and Pragma, reject the Ludus style, and are indifferent to the Mania style. However, the order of preference for love styles is different for men and women and for different age groups. These results are analyzed and discussed.     

Implicit sequence learning in deaf children with cochlear implants

Deaf children with cochlear implants (CIs) represent an intriguing opportunity to study neurocognitive plasticity and reorganization when sound is introduced following a period of auditory deprivation early in development. Although it is common to consider deafness as affecting hearing alone, it may be the case that auditory deprivation leads to more global changes in neurocognitive function. In this paper, we investigate implicit sequence learning abilities in deaf children with CIs using a novel task that measured learning through improvement to immediate serial recall for statistically consistent visual sequences. The results demonstrated two key findings. First, the deaf children with CIs showed disturbances in their visual sequence learning abilities relative to the typically developing normal-hearing children. Second, sequence learning was significantly correlated with a standardized measure of language outcome in the CI children. These findings suggest that a period of auditory deprivation has secondary effects related to general sequencing deficits, and that disturbances in sequence learning may at least partially explain why some deaf children still struggle with language following cochlear implantation.     

BRIEF-P: analysis of executive functions according to informant / BRIEF-P: análisis de las funciones ejecutivas en función del informante

Abstract

Children progressively become more independent in their ability to control their own thoughts, actions and behaviour. This change can be associated with and linked to the development of executive functions, which are observed and contrasted by parents and teachers. The purpose of this study was to identify the perceptions that both parents and teachers have of the development of executive functions in children of different ages. Participants of the study included parents (N = 1,077), teachers (N = 902) and evaluated children (N = 1,979), whose ages ranged from two years to five years and 11 months. We applied the BRIEF-P test. Results showed that when comparing parents’ and teachers’ scores, there were statistically significant differences for all the clinical scales and indices. These data confirm that teachers are more sensitive to the development of executive functions than parents. We conclude that the BRIEF-P is an instrument that is sensitive to the development of executive functions and also to the informant interacting with the child.     

Effects of Training Volume on Hormones and Mood in Basketball Players

Mood and basal hormone levels were measured before and after a 4-month training period in 20 professional basketball players on 2 different teams. Training volume was daily quantified by intensities, showing that Team 1 trained nearly twofold the volume of Team 2. Apart from the lack of differences between teams in anthropometric and physical variables, results showed mood improvements in the total sample without differences between teams. However, cortisol levels decreased in Team 1 and increased in Team 2, while the free testosterone–cortisol ratio, free testosterone, prolactin, and luteinizing hormone did not show significant changes. Changes in cortisol were positively related to depression and negatively related to training volume. Results suggest that differences exist in sensitivity and/or timing of both psychological and hormonal responses to 2 given volumes of training.     

Generational Differences in Subjective Well-Being in Australia

We test for differences in subjective well-being across four pre-defined generations in Australia born between 1928 and 1994: The Lucky Generation, Baby Boomers, Generation X, and Generation Y. We focus on overall life satisfaction and range of domain satisfactions. We find that Baby Boomers are less satisfied with life than thosce born before and after them. We observe similar patterns when considering domains such as finances and housing. However, differences in satisfaction with employment opportunities show the opposite pattern, with Baby Boomers and Generation X’s reporting higher satisfaction as compared to the Lucky Generation and especially those from Generation Y. Family and labour marketcv status have greater effects than cohort of birth on many of the domains studied; however, the cohort effects are significant and non-negligible, particularly concerning satisfaction with life, employment opportunities, and housing.

     

Diferentes procedimientos de externalización de la representación espacial. Un estudio evolutivo con niños ciegos

Resumen

Este artículo analiza los problemas teóricos y metodológicos que plantea el estudio del conocimiento del entorno en las personas ciegas, desde una perspectiva evolutiva. En la primera parte se revisan los aspectos teóricos más importantes implicados en el estudio del desarrollo del conocimiento espacial, haciendo especial énfasis en los problemas derivados de la falta de visión. La segunda parte presenta los resultados de un estudio piloto en el que se investiga el desarrollo del conocimiento espacial en niños invidentes de ocho a catorce años. Se pone especial énfasis en la comparación entre diferentes técnicas de externalización susceptibles de ser utilizadas en invidentes.     

Inhibitory processes, working memory, phonological awareness, naming speed, and early arithmetic achievement

This study identified the cognitive processes that underlie the individual differences in early mathematical performance in elementary school children. Taking into account the Baddeley framework multicomponent model, the inhibitory processes, working memory, phonological awareness, and naming speed are considered to be related to early math learning. To examine this relationship, we compared the performance of a total of 424 typically developing middle-class children, aged between 4 and 7 years in a battery of cognitive and early numeric tests: The Utrecht Early Numeracy Test, the Rapid Automatized Naming Test, Spanish version of the Stroop task, the Numeracy Interference Test, Digit Span test, and Phonological Knowledge Test. The mean age of the participants was 72.21 months (sd = 14.8), and 48.6% were male and 51.4% were female. The results demonstrated that children performing worst on central executive, phonological processing, and inhibitory processes showed lower results in early mathematical tasks measured by The Utrecht Early Numeracy Test. Results supported the notion that the executive system is an important predictor of children's mathematical performance.
