Risk behavior during adolescence results in substantial morbidity and mortality. Sensation seeking consistently relates to engagement in risk behavior, but the psychological mediators of this relationship remain unclear. The current study demonstrates that adolescents’ judgments of the costs versus benefits of risk behavior were a significant mediator of this relationship. Participants were 406 racially and ethnically diverse adolescents ages 12-17 (M = 14.5, SD = 1.7; 48.3% female) who participated in a larger multi-site investigation of personality and neurocognitive predictors of risk behavior. Data were collected via self-report in a single laboratory session. Mediation of the relationship of sensation seeking to risk behavior was tested using structural equation modeling. Results indicated that higher levels of sensation seeking predicted weighing the benefits of risk behavior higher than its costs, which in turn predicted higher levels of risk behavior. Implications of these findings for understanding mechanisms underlying adolescents’ risk behavior and directions for future research are discussed. 相似文献
Effects of sex and handedness on the production of spontaneous and click-evoked otoacoustic emissions (OAEs) were explored in a non-hearing impaired population (ages 17-25 years). A sex difference in OAEs, either produced spontaneously (spontaneous OAEs or SOAEs) or in response to auditory stimuli (click-evoked OAEs or CEOAEs) has been reported in infants and children, but healthy young adults seldom have been the target of study. In the current data, a robust sexual dimorphism was confirmed, with women producing more numerous and stronger SOAEs, and CEOAEs with greater response amplitude compared to men. A right-ear advantage was found for the number of SOAEs produced and, in women, for SOAE power. Although handedness did not moderate the ear asymmetry in production, exploratory analyses revealed that departures from strong right hand preference were associated in the present sample with reduced numbers or strengths of OAEs. The results are discussed with respect to differential exposure to androgens during prenatal development. 相似文献
The experiments conducted aimed to investigate whether reduced accuracy when counting stimuli presented in rapid temporal sequence in adults with dyslexia could be explained by a sensory processing deficit, a general slowing in processing speed or difficulties shifting attention between stimuli. To achieve these aims, the influence of the inter-stimulus interval (ISI), stimulus duration, and sequence length were evaluated in two experiments. In the first that used skilled readers only, significantly more errors were found with presentation of long sequences when the ISI or stimulus durations were short. Experiment 2 used a wider range of ISIs and stimulus durations. Compared to skilled readers, a group with dyslexia had reduced accuracy on two-stimulus sequences when the ISI was short, but not when the ISI was long. Although reduced accuracy was found on all short and long sequences by the group with dyslexia, when performance on two-stimulus sequences was used as an index of sensory processing efficiency and controlled, group differences were found with presentation of stimuli of short duration only. We concluded that continuous, repetitive stimulation to the same visual area can produce a capacity limitation on rapid counting tasks in all readers when the ISIs or stimulus durations are short. While reduced accuracy on rapid sequential counting tasks can be explained by a sensory processing deficit when the stimulus duration is long, slower processing speed in the group with dyslexia explains the greater inaccuracy found as sequence length is increased when the stimulus duration is short. 相似文献
Successful communication requires that individuals attend to the perspective of their conversational partners and use this information to modify their behavior accordingly. This paper presents a framework by which to understand children’s communicative perspective-taking skills and, within this framework, outlines three routes by which children’s communicative perspective-taking performance can be disrupted. First, children may have difficulty in communicative contexts due to deficits in mentalizing ability whereby they are unable to appreciate another’s perspective. Second, children may have intact mentalizing abilities but do not have the cognitive skills to support the use of this information when generating communicative behaviors. Third, decreased social exposure may lead to exacerbated deficits in either mentalizing ability or the use of mentalistic information within communicative contexts. Patterns within both typical and atypical populations (i.e., autism, ADHD, and mood disorders) are reviewed. 相似文献
Elder mistreatment is now recognized as a worldwide social problem occurring in all racial and ethnic groups. The research on elder mistreatment started in the late 1970s and expanded its focus to ethnic elderly groups including Asian elders in the mid-1980s. Many researchers have explored the issues of elder mistreatment in conjunction with Asian elders’ culture and immigration backgrounds. This article reviews the state of the literature on elder mistreatment among Asians living in Asia or abroad to identify future directions of research, prevention, intervention, and policy. This research indicates that prevention, education, and intervention must take into account the cultural backgrounds of Asian elders and their family members. There is clearly a need for greater research into appropriate elder mistreatment prevention and intervention with Asian elders and their family members. 相似文献
Judgment is widely recognized as an important executive function, and deficits in judgment can lead to health risks, safety concerns, and hospitalizations. Surprisingly, relatively few tests of judgment have been developed specifically for older adults—a population particularly vulnerable to executive and functional declines. The Kitchen Picture Test (KPT) is a new screening measure of practical judgment. In two independent studies (Study 1, N = 99 nursing home patients; Study 2, N = 163 nursing home and assisted living patients), psychometric analyses confirmed strong evidence for reliability, construct validity, and predictive validity. A receiver operating characteristic (ROC) curve was calculated from sensitivity and 1-specificity values for diagnoses of dementia versus no dementia. A KPT cut score can be used for identifying persons to be referred to appropriate health-care professionals who have specific expertise in the evaluation and treatment of cognitive impairment. 相似文献
This paper provides a sketch of an agent-centered way of understanding and answering the question, “What’s wrong with that?” On this view, what lies at the bottom of judgments of wrongness is a bad attitude; when someone does something wrong, she does something that expresses a bad, or inappropriate, attitude (where inappropriateness is understood, tentatively, as a failure to recognize the separateness of others). In order to motivate this account, a general Kantian agent-centered ethics is discussed, as well as Michael Slote’s agent-based ethics, in light of analysis of the grounding role of attitudes in the evaluation of two core cases. In light of these discussions, it is argued that there are advantages to preserving the grounding of the appropriateness of attitudes in facts about their objects (as opposed to Slote’s sentimentalism), while cutting such an agent-centered ethics away from a Kantian grounding. 相似文献

Youth who experience aggression at the hands of peers are at an increased risk for a variety of adjustment difficulties, including depressive and anxiety symptoms and lower self-esteem. The links between peer victimization and internalizing problems are robust, but less work has been done to identify individual-level protective factors that might mitigate these outcomes. The current study investigated whether hope served as a moderator of the prospective links from peer victimization to depressive and anxiety symptoms and self-esteem during adolescence. Participants included 166 high school students (64% female; 88% Black/African American). Youth completed self-report measures at three different time points across the Spring semester of an academic year. As predicted, hope interacted with peer victimization to predict changes in depressive and anxiety symptoms over the course of the semester. That is, for youth with low levels of hope, peer victimization predicted more stable patterns of depressive and anxiety symptoms. For adolescents with average levels of hope, however, peer victimization did not influence anxiety and depressive symptoms over time. Finally, for adolescents with high levels of hope, peer victimization predicted greater decreases in anxiety symptoms over time. Hope did not interact with peer victimization to predict self-esteem. Rather, hope uniquely predicted higher levels of self-esteem, whereas peer victimization uniquely predicted lower levels of self-esteem. The current study provides initial support for the notion that hope can serve as a protective factor among youth who are victims of peer aggression.
