The aim of this study was to investigate, within a social comparison framework, the causal relationship between adolescents’ use of sexually explicit Internet material (SEIM) and their sexual satisfaction. In addition, we tested which adolescents were most susceptible to a potential influence of SEIM on sexual satisfaction. Between May 2006 and May 2007, we conducted a three‐wave panel survey among 1,052 Dutch adolescents aged 13–20. Structural equation modeling revealed that exposure to SEIM consistently reduced adolescents’ sexual satisfaction. Lower sexual satisfaction (in Wave 2) also increased the use of SEIM (in Wave 3). Moderator analyses showed that the negative effect of SEIM on sexual satisfaction was stronger for adolescents who had no or limited sexual experience as well as for adolescents who perceived the majority of their peers to be sexually inexperienced. The effect of exposure to SEIM on sexual satisfaction did not differ among male and female adolescents. 相似文献

Solving formal analogy problems requires the identification of an initial term and the transformation that occurs between the initial two terms as well as the determination of the final term. Experiment 1 tested 24‐month‐olds' ability to determine final terms when they were shown the initial term and told the transformation that was to occur. Children selected their responses from an array of two principled distracters. The children were able to determine the correct final term when they were given information about the initial term and transformation. Experiment 2 tested 24‐month‐olds' ability to solve final‐term problems, partial analogies, and complete analogies. The children solved all the three types of problems. 相似文献

AbstractThis ethnographic case study explores the dynamic and fluid development of one African-American student’s bilingual/biliterate identity through her enrollment in a Spanish-English Dual Language Education program. We integrate the frameworks of identity in interaction and monoglossic and raciolinguistic language ideologies to understand how this student approaches her Spanish language and literacy development from kindergarten to grade 5. The study documents the fluid nature of the focal student, Tamara’s, identity as she journeyed from a Spanish enthusiast in kindergarten who embraced her emerging bilingualism/biliteracy to a student who seemed to question her identity as Spanish literate person. Specifically, we examine her affective response to developing bilingualism and biliteracy. We identify three paradoxical influences, or double-binds, in how she was differently positioned across multiple interactions as a bilingual African-American student. 相似文献

ABSTRACTDevelopment of autobiographical memory is as a gradual process beginning in early childhood and continuing through late adolescence. Substantial attention has been paid to early childhood when first personal memories are formed; less attention has been focused on the flourishing of memories from the late preschool years onward. We addressed this void with a three-year cohort-sequential study of age-related changes in the length, completeness, and coherence of autobiographical narratives by children 4–10 years. We also examined the unique and combined variance in autobiographical narrative explained by children’s own language, maternal narrative style, domain-general cognitive abilities, non-autobiographical story recall, and memory-specific skills. There was substantial growth in autobiographical narrative skill across the 4–10-year period. Non-autobiographical story recall was a strong concurrent and cross-lagged predictor for all autobiographical narrative measures. Memory-specific and domain-general cognitive abilities systematically predicted narrative completeness and coherence but not length. Children’s language and maternal narrative style did not contribute additional variance when these predictors were considered. The findings highlight that age-related changes in autobiographical memory are the results of combined contributions of a variety of domain-general and domain-specific predictors. 相似文献

Theories are needed to explain and predict health behavior, as well as for the design and evaluation of interventions. Although there has been a history of developing, testing, applying, and refining health behavior theories, debates and limitations in evidence exist: The component of theories which, for example, predicts change should be better elaborated so that we can more easily understand what actually drives behavior change. Theories need to be empirically testable in two ways. Theories need to specify a set of changeable predictors to describe, explain, and predict behavior change, and they should enable us to design an effective intervention that produces exactly those changes in behavior that are predicted by the relevant theory. To make this possible, theories need to be specified in such a way that they can be rigorously tested and falsified. Moreover, for the design of theory-based interventions it must be possible to derive change techniques from the theory and to use them to generate changes in behavior. Based on eight state-of-the-science articles that make conceptual and empirical contributions to the current debate on health behavior theories, various approaches are discussed to gain further insights into explaining and changing health behaviors and the iterative process of theory development. 相似文献
