Using a school-based sample of Washington, DC, fifth graders (mean age 10.38, SD = 0.66) and their parents (N = 408), we examined associations of pubertal development with early adolescents' sexual and nonsexual risk behaviors and their caregivers' parenting behaviors; and of these risk behaviors with parenting behaviors. Youths reporting signs of pubertal development were more likely to engage in these risk behaviors than students reporting no signs. Pubertal development was not related to parenting behaviors; however, parents of youths who reported multiple nonsexual risk behaviors reported more parent-child communication about sexual topics. These results highlight the need to begin risk prevention efforts early, prior to pubertal development. Research is needed to understand how parents can help youths better cope with pubertal development to avoid involvement in sexual and nonsexual risk behaviors.  相似文献

Young and older adults studied word pairs and later discriminated studied pairs from various types of foils including recombined word-pairs and foil pairs containing one or two previously unstudied words. We manipulated how many times a specific word pair was repeated (1 or 5) and how many different words were associated with a given word (1 or 5) to tease apart the effects of item familiarity from recollection of the association. Rather than making simple old/new judgments, subjects chose one of five responses: (a) Old-Old (original), (b) Old-Old (rearranged), (c) Old-New, (d) New-Old, (e) New-New. Veridical recollection was impaired in old age in all memory conditions. There was evidence for a higher rate of false recollection of rearranged pairs following exact repetition of study pairs in older but not younger adults. In contrast, older adults were not more susceptible to interference than young adults when one or both words of the pair had multiple competing associates. Older adults were just as able as young adults to use item familiarity to recognize which word of a foil was old. This pattern suggests that recollection problems in advanced age are because of a deficit in older adults' formation or retrieval of new associations in memory. A modeling simulation provided good fits to these data and offers a mechanistic explanation based on an age-related reduction of working memory.  相似文献

Our contention is that all of the major arguments for abortion are also arguments for permitting infanticide. One cannot distinguish the fetus from the infant in terms of a morally significant intrinsic property, nor are they morally discernible in terms of standing in different relationships to others. The logic of our position is that if such arguments justify abortion, then they also justify infanticide. If we are right that infanticide is not justified, then such arguments will fail to justify abortion. We respond to those philosophers who accept infanticide by putting forth a novel account of how the mindless can be wronged which serves to distinguish morally significant potential from morally irrelevant potential. This allows our account to avoid the standard objection that many entities possess a potential for personhood which we are intuitively under no obligation to further or protect.  相似文献

Through stress generation, individuals’ own thoughts and behaviors can actually lead to increases in their experience of stress. Unfortunately, stress generation is especially common among individuals who are already suffering from elevated depressive symptoms. However, despite the acknowledgement that some individuals with depressive symptoms generate greater stress than others, few studies have identified specific factors that could exacerbate stress generation among individuals with depressive symptoms. The present study examines co-rumination as a factor that might exacerbate stress generation among adolescents with depressive symptoms using a short-term longitudinal design. Considering these processes among adolescents was critical given that many youth experience increases in depressive symptoms at this developmental stage and that co-rumination also becomes more common at adolescence. Participants were 628 adolescents (326 girls; 302 boys) who reported on their depressive symptoms, experiences of stress, and co-rumination with a best friend. Interpersonal stressors (peer and family stress) and non-interpersonal stressors (school and sports stress) were assessed. Consistent with past research, adolescents with depressive symptoms experienced greater interpersonal and non-interpersonal stress over time. Importantly, co-rumination interacted with both depressive symptoms and gender in predicting increases in peer stress. Depressive symptoms predicted the generation of peer stress only for girls who reported high levels of co-rumination with friends. Implications for protecting youth with depressive symptoms against stress generation are discussed.  相似文献

Much variability in social behavior is intra-individual; people vary their actions strategically across contexts. Yet most personality assessment methods are inter-individual; they chart between-person differences in average behavioral tendencies. The present research advanced novel idiographic assessment methods to predict intra-individual variability in a behavioral domain of long-standing interest to personality psychologists: humor. Individuals participated in three assessment sessions. Personal beliefs about reasons for using humor were assessed either idiographically or with respect to a nomothetic system of humor-related reasons for action. The subjective relevance of nomothetically- and idiographically-identified reasons to everyday social situations was assessed. Subsequently, participants reported their perceived likelihood of using humor in specific social contexts. As predicted, likelihood of humor use varied substantially as a function of the relevance of situations to idiographically-identified reasons, but did not vary as a function of the relevance of situations to reasons identified nomothetically. Implications for personality and assessment are discussed.  相似文献

Noninvasive prenatal testing (NIPT) allows for highly sensitive detection of Down syndrome early in pregnancy with no risk of miscarriage, therefore potentially increasing the number of pregnancies identified with Down syndrome. This study assesses how mothers of children with Down syndrome perceive NIPT, especially the impact they think it will have on their families and other families with children who have Down syndrome. Seventy-three self-reported mothers of children with Down syndrome responded to an anonymous online survey emailed to, and posted on, message boards of various Down syndrome support groups and networks. Data analysis included chi-square tests and thematic analysis. Fifty-nine percent of respondents indicated they would use NIPT in the future; respondents who had not used prenatal testing in the past were significantly less likely to report interest in using NIPT in the future than those who had prenatal testing previously (p?MOST important factor. They also highlight the need to provide a diagnosis of Down syndrome in a balanced and objective manner.  相似文献

In research on cognitive plasticity, two training approaches have been established: (1) training of strategies to improve performance in a given task (e.g., encoding strategies to improve episodic memory performance) and (2) training of basic cognitive processes (e.g., working memory, inhibition) that underlie a range of more complex cognitive tasks (e.g., planning) to improve both the training target and the complex transfer tasks. Strategy training aims to compensate or circumvent limitations in underlying processes, while process training attempts to augment or to restore these processes. Although research on both approaches has produced some promising findings, results are still heterogeneous and the impact of most training regimes for everyday life is unknown. We, therefore, discuss recent proposals of training regimes aiming to improve prospective memory (i.e., forming and realizing delayed intentions) as this type of complex cognition is highly relevant for independent living. Furthermore, prospective memory is associated with working memory and executive functions and age-related decline is widely reported. We review initial evidence suggesting that both training regimes (i.e., strategy and/or process training) can successfully be applied to improve prospective memory. Conceptual and methodological implications of the findings for research on age-related prospective memory and for training research in general are discussed.  相似文献

In reviews published more than 30 years ago, eight parameters important to the use of time-out were identified and available research was summarized. The purpose of the current paper is to provide an updated summary of existing research for each parameter of time-out. Within each parameter, we conducted a thorough review of the published literature and identified all peer-reviewed articles addressing each parameter. We identified and summarized a total of 46 articles across the eight parameters, including 32 not cited in previous reviews. Sufficient findings were available to draw conclusions regarding time-out warning, schedule of time-out, contingent versus noncontingent release, and duration. Tentative conclusions based on only a few studies could be drawn in regard to instructional versus physical administration and verbalized reason for time-out. No conclusions could be drawn regarding time-out signal and specific time-out location. While we know much more today regarding effective implementation of time-out, there is a clear need for further exploration within these identified parameters. In addition to summarizing the literature, we reviewed recommendations made by behavioral parent training programs, parenting books, and parenting Web sites, and compared how well their recommendations matched current research based on the conclusions drawn from our review. We found that parenting sources made strong and specific recommendations on several of the parameters that were either not consistent with available research or simply lacked a sufficient research base.  相似文献

The goal of the present study was to examine clinician, supervisor, and organizational factors that are associated with the intensity of evidence-based treatment (EBT) focus in workplace-based clinical supervision of a specific EBT, Trauma-Focused Cognitive Behavioral Therapy (TF-CBT). Supervisors (n = 56) and clinicians (n = 207) from mental health organizations across Washington State completed online self-report questionnaires. Multilevel modeling (MLM) analyses were used to examine the relative influence of nested clinician and supervisor factors on the intensity of EBT focus in supervision. We found that 33% of the variance in clinician report of EBT supervision intensity clustered at the supervisor level and implementation climate was the only significant factor associated with EBT supervision intensity. While individual clinician and supervisor factors may play a role in EBT coverage in supervision, our results suggest that an implementation climate that supports EBT may be the most critical factor for improving intensity of EBT coverage. Thus, implementation efforts that address the extent to which EBTs are expected, rewarded, and supported within an organization may be needed to support greater coverage of EBT during workplace-based supervision.  相似文献

What factors determine whether mixed-race individuals claim a biracial identity or a monoracial identity? Two studies examine how two status-related factors-race and social class-influence identity choice. While a majority of mixed-race participants identified as biracial in both studies, those who were members of groups with higher status in American society were more likely than those who were members of groups with lower status to claim a biracial identity. Specifically, (a) Asian/White individuals were more likely than Black/White or Latino/White individuals to identify as biracial and (b) mixed-race people from middle-class backgrounds were more likely than those from working-class backgrounds to identify as biracial. These results suggest that claiming a biracial identity is a choice that is more available to those with higher status.  相似文献
