This study examines associations between childhood maltreatment and developmental trajectories of sexual risk behaviors (SRBs) in a sample of 882 sexually active adolescent girls, predominantly Hispanic or Black, assessed every 6 months between 13 and 23 years. Latent profile analyses revealed four distinct maltreatment profiles: Low Maltreatment (76%), Moderate Emotional Neglect Only (15%), Severe Physical/Emotional Abuse (3%), and Severe Sexual Abuse (6%). Multilevel growth analyses showed the Moderate Emotional Neglect Only and Severe Sexual Abuse profiles exhibited more SRBs starting in late adolescence, and the Severe Sexual Abuse profile also exhibited a faster increase than the Low Maltreatment profile. Understanding heterogeneity within maltreated populations may have important implications for healthy sexual development.  相似文献

Longitudinal twin data were analyzed to investigate the etiology of the stability of genetic and environmental influences on word reading and reading comprehension, as well as the stability of those influences on their relationship. Participating twin pairs were initially tested at a mean age of 10.3 years, and retested approximately five years later. Both word reading and comprehension were found to be highly stable, and genetic influences were primarily responsible for that stability. In contrast to studies with younger participants, no unique genetic influences were observed at follow-up testing in this older sample. High genetic correlations were obtained between word reading and reading comprehension at both ages, indicating common genetic influences. However, significant genetic influence on comprehension was also observed, independent of that on word reading. Although the phenotypic relation between the two measures appeared to decline across time, the genetic etiology of this relation was highly stable.  相似文献

A significant gap in emerging literacy intervention with preschoolers relates to a skill that is crucial to later reading comprehension–the ability to engage in inferencing. This article presents a theoretical rationale for fostering inferential language during book sharing with preschool children, and provides research‐based ideas for how this can be best accomplished. It is suggested that, at the preschool level, children can be supported in their ability to make inferences about stories read aloud to them by having adults ask both literal and inferential questions that, first and foremost, relate to the causal structure of stories. Additionally, questions focused on informational and evaluative inferences serve to further enhance story comprehension. A rubric for connecting such questions to the elements of story grammar is offered, and a specific example from a published preschool level storybook is provided. © 2008 Wiley Periodicals, Inc.  相似文献

Parenting has a significant and lasting impact on child development. From birth, parents must sensitively and appropriately attend to their infant’s emotional expressions and vocalizations. Accumulating evidence indicates that these infant cues of emotion attract more attention than equivalent adult cues in parents as well as non-parents. We review this evidence and suggest that infant cues hold high incentive value and elicit motivated attention (i.e., enhanced processing of motivationally relevant stimuli), which in turn promotes approach motivation and thus caregiving responses. Further, we discuss data suggesting that infant cues are salient for non-parents, with increasing motivated attention to infant cues in the transition to parenthood. This increase may depend on interactions between the dopamine reward system and the neuropeptide oxytocin. Therefore, we also explore the human and non-human data that support this association and consider potential sources of variability in motivated attention in parents.  相似文献

Children's literacy environments and early word recognition subskills   总被引:1,自引:0,他引:1  
First-grade children completed a battery of tasks that included standardized measures of word recognition and spelling, measures of phonological and orthographic processing skill, and a short indicator of exposure to print via home literacy experiences. Phonological and orthographic processing skill were separable components of variance in word recognition. Orthographic processing ability accounted for variance in word recognition ability even after the variance in three phonological processing measures had been partialed. Additionally, variance in orthographic processing ability not explained by phonological abilities was reliably linked to differences in print exposure. The print exposure measure was not, however, linked to the measures of phonological processing. This finding was unexpected but it is consistent with some previous research. The theoretical implications of this result are discussed.  相似文献

To understand both immediate and longer-term effects of a short duration, interpretive wildlife tourism program, we studied responses from participants in a sea turtle watch program. This program comprised an interpretive presentation followed by an opportunity to view a nesting loggerhead sea turtle (Caretta caretta). We conducted 37 programs in 2013 and 2014, for 843 participants, of whom 70.5% were able to see a nesting turtle. We measured participant attitudes, knowledge, intention to act, and long-term behavior change. Initial participant responses indicated prior interest in nature and environmental topics, and a knowledge base focused on biological sea turtle information. After the interpretive presentation, participants chose to provide conservation-related information as opposed to natural history-related information. Intention to engage in conservation behaviors was high following the turtle watch experience, regardless of whether a turtle was seen. The conservation value of our turtle watch program is expressed through conservation-focused knowledge acquisition by participants and their high post-program intention to engage in behaviors benefiting sea turtles, both of which precede long-term behavior change in an interdisciplinary model of behavior change.  相似文献

This paper reports part of a larger study into the learning of the general public during visits to an interactive science centre. Much previous research on visitors' learning has focused on students, whereas the explainers, who have most interaction with visitors, have rarely been used as a data source. Reported here are the views of a representative sample of explainers from a science centre. Data were collected through interviews and conclusions scrutinised by a wider group of explainers. The findings suggest that explainers believe that first, visitors have fun at the centre; second, learning is not the main purpose of the visit; third, their own role is to facilitate understanding of the exhibits, not to teach; fourth, learning occurs when visitors relate experiences at the centre to experiences in the outside world; fifth, analogies facilitate understanding; and sixth, incidental learning, unrelated to the intention of an exhibit, often occurs. Specializations: interactive science and technology centres. Specializations: gender issues and assessment in science and technology education.  相似文献

Parental support has been an increasingly essential part of New Zealand early childhood (EC) education services over the last 20 years. This support has taken many shapes and forms over this time period, and has depended on the differing philosophies of the EC education services. What this support ‘looks like’ and how it is delivered is directly connected to the goals and aims of these services. This paper will discuss the results from a small qualitative study that looked at how three New Zealand EC centres—two kindergartens and one child care centre—supported family resilience; that is, the ability of an individual and family to ‘cope’ with and ‘recover’ from significant adversity or stress, in ways that are not only effective but may result in increased ability to ‘respond’ to and ‘protect’ their families from future adversity. From semi‐structured interviews with teachers, parents, and family support services associated with each of the three centres, the concept of planned parent education programmes, as meaningful support, is re‐examined in the light of the ideas of a ‘gossip’ or a ‘good yack’. This research was funded by the New Zealand Ministry of Social Development.  相似文献
