Developmental pattern of digit span in Spanish population

This study examined in a Spanish population the developmental pattern of digit span, as an index of one of the components of Baddeley's working memory--the phonological loop. A verbal digit span was administered to 570 participants ranging from 5 to 17 years old. The results indicated that the digit memory span increases until age 17 as opposed to Anglo-Saxon data--where it is established that this span reaches a peak by age 15. Additionally, these results were compared to the performance in the same task of healthy elderly, Alzheimer disease patients, and Frontotemporal dementia patients, examined in a previous study. The analysis shows that the phonological loop is affected by age and not so much by dementias.     

Is dyslexia a visual perceptive disorder? New empirical data

Several studies have shown that a phonological deficit is the origin of developmental dyslexia, because dyslexics have important difficulties in mapping orthographic to phonological codes. However, visual criteria are still used for the diagnosis of dyslexia and to develop methods of intervention. This study attempts to determine whether there are visual problems in dyslexic children. To this aim, dyslexic children and children without reading difficulties, matched by chronological age, participated in two experiments. One study was based on the Reversal test and the other was a visual decision task in which participants had to decide whether two letters were the same or different. There were 40 pairs of letters, to measure reaction times and mistakes. The results showed that dyslexics had similar performance to controls in the detection of different visual stimuli. Developmental dyslexics do not appear to have visual perceptual problems, but a particular difficulty to retrieve the phonological code of graphemes.     

Cross cultural differences in unconscious knowledge

Previous studies have indicated cross cultural differences in conscious processes, such that Asians have a global preference and Westerners a more analytical one. We investigated whether these biases also apply to unconscious knowledge. In Experiment 1, Japanese and UK participants memorized strings of large (global) letters made out of small (local) letters. The strings constituted one sequence of letters at a global level and a different sequence at a local level. Implicit learning occurred at the global and not the local level for the Japanese but equally at both levels for the English. In Experiment 2, the Japanese preference for global over local processing persisted even when structure existed only at the local but not global level. In Experiment 3, Japanese and UK participants were asked to attend to just one of the levels, global or local. Now the cultural groups performed similarly, indicating that the bias largely reflects preference rather than ability (although the data left room for residual ability differences). In Experiment 4, the greater global advantage of Japanese rather English was confirmed for strings made of Japanese kana rather than Roman letters. That is, the cultural difference is not due to familiarity of the sequence elements. In sum, we show for the first time that cultural biases strongly affect the type of unconscious knowledge people acquire.     

Agentic and Communal Personality Traits: Their Associations with Depression and Resilience among Transgender Women

Research reports the perpetuation of communal traits by transgender women, possibly to affirm their core gender identity. Transgender women in the United States are nearly 6 times more likely than the general population to experience significant depressive symptoms. Studies among non-transgender individuals in the United States demonstrate that agentic traits are associated with less depressive symptoms, while studies on communal traits are more inconsistent in their association with indicators of depression. Our study’s central objective was to examine the associations of agency and communion with depression and resilience (i.e., personal competence and acceptance of self and life) among transgender women living part-time and full-time in the female gender role. Participants in the United States were recruited through online and offline purposive sampling. One hundred and twenty-two transgender women (primarily Caucasian; ages ranging from 22 to 75) completed a web-based questionnaire. Results indicated that agentic and communal traits were significantly associated with decreased symptoms of depression and increased levels of resilience. One component of resilience – acceptance of self and life – mediated the relationship between agentic/communal traits and depression, however, for communal traits this pattern was only found for transgender women living in the female role full-time. There were no significant differences on depressive symptoms and one component of resilience - personal competence – among transgender women living full-time compared to transgender women living in the female role part-time. Transgender women living full-time in the female gender role reported higher levels of agentic/communal traits and acceptance of self and life compared to those living part-time in the female gender role. Our findings are discussed in the context of mental health among transgender women.     

Parental and Secondary School Teachers’ Perceptions of ICT Professionals, Gender Differences and their Role in the Choice of Studies

The influence of parents and teachers in the decisions made by adolescents regarding study options has not been widely documented in Spain. The main aim of this qualitative study consisted of analyzing the opinions of parents and secondary school teachers about their role in the different academic and professional choices boys and girls make. Seven focus groups (4 with 27 parents and 3 with 22 secondary school teachers) from 5 schools located in urban and rural areas of Catalonia (Spain) were carried out in order to explore how both groups perceive Information and Communication Technology (ICT) professionals, gender differences in study options and their own role in adolescents’ choice of study options. Our findings show that parents and teachers hold stereotypes about ICTs and consider that gender does not condition adolescents’ study choices. Both groups saw themselves as playing a secondary role in adolescents’ academic and professional choices. Some gender differences among parents and teachers emerged regarding their perception of the ICT professionals and their own role and of others in shaping adolescents’ study choices.?The findings and their practical implications are discussed.     

Work-family and family-work conflict: does intrinsic-extrinsic satisfaction mediate the prediction of general job satisfaction?

The objective of this study is to analyze the mediating role of intrinsic and extrinsic job satisfaction in the relationship between the 2 dimensions of work-family conflict-family interfering with work (FIW) and work interfering with family (WIF)-and general job satisfaction. Step-by-step hierarchical regression analyses were carried out on a sample of 151 men and women from a Spanish public organization. The results confirmed the mediating role of intrinsic job satisfaction in the case of FIW. This highlights the importance of taking into account the level of satisfaction with the intrinsic facets of one's job as a measure for understanding why FIW has a negative impact on general job satisfaction.     

An Inferential Conception of the Application of Mathematics

A number of people have recently argued for a structural approach to accounting for the applications of mathematics. Such an approach has been called “the mapping account”. According to this view, the applicability of mathematics is fully accounted for by appreciating the relevant structural similarities between the empirical system under study and the mathematics used in the investigation of that system. This account of applications requires the truth of applied mathematical assertions, but it does not require the existence of mathematical objects. In this paper, we discuss the shortcomings of this account, and show how these shortcomings can be overcome by a broader view of the application of mathematics: the inferential conception.
