Behavioural factors underlying innovative problem-solving differences in an avian predator from two contrasting habitats

Animal Cognition - Innovative behavior is considered one of the main factors facilitating the adaptation of animals to urban life. However, the relationship between urbanization and innovativeness...     

The Role of Hope, Spirituality and Religious Practice in Adolescents’ Life Satisfaction: Longitudinal Findings

This longitudinal study presents the first examination of the relation between hope, spirituality, religious practice and life satisfaction of students in Portugal. A sample of 227 adolescents aged 15–19 completed the Portuguese versions of the Children Hope Scale, Students’ Life Satisfaction Scale and a single item for each spirituality and religious practice variable. The results from the cross-sectional and longitudinal analyses suggest that hope and spirituality, but not religious practice, were strongly linked to adolescents’ life satisfaction. Hope significantly predicted life satisfaction at a single time point, 6-months and 1-year later, and spirituality scores added significant variance beyond hope scores. All the variables demonstrate moderate to high stability across 6-months and 1-year time frame; no significant changes were found between the variables across the administrations. These results parallel recent studies of adult and child life satisfaction and suggest strategies to promote life satisfaction in adolescents.     

Estrategias de comprensión del lenguaje. El desarrollo de la capacidad metalingüística

RESUMEN

Es este un artículo dedicado a la capacidad metalingüística, en la compresión de lenguaje, en el que se precisan algunas de las ideas de anteriores trabajos, sobre la génesis de la capacidad metalingüística del niño. Se basa el trabajo en la necesidad de emplear claves contextuales en las funciones de compresión (de la distinción sujeto-objeto, en este caso). La investigación presentada permite establecer varios niveles en las estrategias de compresión y captación de errores lingüísticos, centrándose especialmente en un nivel “intermedio” de desarrollo de la competencia metalingüística, caracterizado por respuestas oscilatorias entre los niños que requieren claves contextuales (aunque sean internas) para permitir la comprensión y aquellos otros, de nivel “formal”, en que dichas claves ya no son necesarias y de una captación consistente de los errores lingüísticos.     

Reference and ethnic-group terms

The increasingly pluralistic character of modern societies has led to questions, not only about the proper use of ethnic-group terms, but also about the correct semantic analysis of them. Here I argue that ethnic-group terms are analogous to other linguistic expressions whose extension is fixed in the way suggested by a causal theory of reference. My view accommodates precisely those scenarios of communication involving ethnic-group terms that will be seen puzzling to Fregeans. At the same time, it undermines the plausibility of skepticism about those terms.     

Psychometric properties of the Escala de Autoeficacia para el Afrontamiento del Estrés (EAEAE)

This paper presents the theoretical construct of and an instrument for its assessment, the Escala de Autoeficacia para el Afrontamiento del Estrés (EAEAE; in English, Coping with Stress Self-Efficacy Scale), as well as the results obtained concerning its psychometric properties from an adult population. 812 individuals, aged 18 to 64 years old ( M = 26.46, SD = 9.93, 62.6% females and 37.4% males), recruited from various contexts, participated in this study. Participants completed the EAEAE along with other measures of constructs theoretically related to this specific self-efficacy. The EAEAE shows appropriate reliability in its complete form as well as in its two subscales of Efficacy Expectations and Outcome Expectations, and adequate factorial construct validity (which reveals the bi-dimensionality of the instrument), and convergent validity with the remaining measures. The characteristics of brevity and ease of application of the scale, in addition to its adequate psychometric properties, indicate that the EAEAE is an appropriate tool to assess and investigate coping with stress self-efficacy in research as well as clinical settings.     

Parenting styles

Parental educational styles constitute one of the key elements of family socialization. The aim of the present essay is to present the results of a research project carried out in the Principality of Asturias (Spain) among 2,965 families with children of infant and primary-school age (5-8 years old). This research attempts to analyse, among other aspects, parental behaviour tendencies in child upbringing. The analysis of the results obtained allows us to: 1) identify the most common attitudinal and behavioural tendencies of parents in the upbringing of their children; 2) determine how many people have a well defined parental style, and delimit their socio-educational characteristics. Lastly, we consider the need to change some parental behaviour patterns and stress the importance of family education programmes, with the aim of promoting appropriate parenting models and modifying or improving current practices.     

Physical self-concept, anxiety, depression, and self-esteem in children with cancer and healthy children without cancer history

The main purpose of this study is to test if children with cancer receiving chemotherapy show a poorer physical self-concept, less self-esteem and more anxiety and depression than healthy children (with no cancer history) within the same age range (9-16 years old) and social condition. Furthermore, the capacity of self-concept and self-esteem to predict emotional distress is analyzed. The Spanish versions of PSDQ, CDI and STAIC were administered to 30 children with cancer and 90 healthy children. Except for the health and flexibility dimensions in the PSDQ, no significant differences between groups were found. Self-esteem was the best predictor of depression, whereas health and self-concept predicted anxiety.     

Processing two tasks with varying task order: central stage duration influences central processing order

In a recent study, Sigman and Dehaene (2006, PLoS Biology, 4, 1227–1238) reported that perceptual processing duration influences processing order of two tasks in the psychological refractory period paradigm (PRP). The present study examines whether the duration of central processes also influences processing order. For this purpose, we employed letter tasks with different central processing durations and varied task order in the PRP. In one part of the experiment, a tone discrimination task was combined with a similar time-consuming letter discrimination task. In the other part, the tone task was combined with a more time-consuming letter task, which required a mental rotation of the letter thereby prolonging central processing. If the duration of central processes influences processing order, participants should perform the tone task first more often when it is presented with the more time-consuming mental rotation task, than when it is presented with the similar time-consuming letter task. The results clearly confirm this prediction and thus show that not only perceptual processing duration but also central processing duration affects processing order in a dual-task situation. We suggest that the reported effect mirrors a tendency of participants to minimize total reaction time to both tasks by reducing slack time.     

Father involvement and marital relationship during transition to parenthood: differences between dual and single-earner families

Research into the process of becoming mother or father shows very conclusively that this important life transition is accompanied by both a decrease in marital quality and a more traditional division of labour. In this paper these changes are analyzed with special emphasis on the relationships between them and exploring the role played in this process by the mother's work status. Results showed a significant link between the development of marital quality and violated expectations regarding father involvement on childrearing. Dual-earner families were characterized by a specific pattern of changes, with greater stability than single-earner families in marital and parental roles during transition to parenthood and a significant role played by spouse support as a partner, but not as a parent.
