The Development of Impulse Control and Sensation‐Seeking in Adolescence: Independent or Interdependent Processes? 下载免费PDF全文
Elizabeth P. Shulman Kathryn Paige Harden Jason M. Chein Laurence Steinberg 《Journal of research on adolescence》2016,26(1):37-44
This study examines whether changes in impulse control and sensation‐seeking across adolescence and early adulthood reflect independent or interdependent developmental processes. Data are drawn from a national longitudinal study (N = 8,270; 49% female; 33% Black, 22% Hispanic, 45% non‐Black, non‐Hispanic). An autoregressive latent trajectory model is used to test whether development in one trait influences development in the other. Although levels of these traits are inversely correlated, we do not find evidence that change over time in either trait is influenced by the prior level of the other. This failure to reject the null hypothesis is consistent with the view that sensation‐seeking and impulse control are the products of distinct neuropsychological systems that develop independently of one another. 相似文献

This article examines the prevalence of intimate partner violence (IPV) among a national sample of Internet-recruited U.S. men who have sex with men (MSM) (n = 1,575), and associations between reporting of IPV, minority stress, and sexual risk-taking. Five outcomes are examined: experiences of physical and sexual violence, perpetration of physical and sexual violence, and unprotected anal intercourse (UAI) at last sexual encounter. MSM who reported experiencing more homophobic discrimination and internalized homophobia were more likely to report experiences of IPV. The results point to the need for prevention messages to address the external and internal stressors that influence both violence and sexual risk among MSM. 相似文献

How peer groups contribute to educational outcomes has long interested researchers. However, the possibility that peer groups dominated by either low- or high-achieving youth can have substantively different effects on achievement has been largely ignored. In this paper, we show that while being embedded in a high-achieving network of friends is not associated with increased own achievement, being embedded in a low-achieving network is associated with decreased own achievement. In additional analyses, we present evidence that these associations are at least in part due to influence, as opposed to only selection effects or shared environment. We also examine whether the structure of the network in which a student is embedded might affect their educational achievement. We show that achieving at higher levels positively predicts how centrally located a student is in their network, but being more centrally located does not predict concurrent achievement. This finding suggests that the behavior of individuals is affecting the formation of network structure and not the reverse. 相似文献

Using a convenience sample of 318 undergraduate and graduate social work students (193 women and 125 men) from a public university in India, this study examined the differences between Indian social work students' perceptions toward the role of government in addressing social issues in India. Using Predictive Analytics Software (PASW) 18, several statistical procedures were conducted to analyze the relationship between social work students' demographic variables and their perceptions of the government's role in addressing social issues in India. The results indicated that older social work students were more likely to perceive that the government should ensure equal opportunities for citizens. Female social work students were more likely to perceive that the government should ensure housing for citizens. BSW students were more likely to perceive that the government should ensure employment of citizens. Macro social work students were more likely to perceive that the government should ensure equal opportunities, housing, food, employment, and health insurance for citizens. The findings of this study may help social work educational administrators and faculty in India to develop a curriculum that provides social work students with the opportunity to critically examine the complex relationship between age, gender, marital status, number of children, socioeconomic status, educational status, area of concentration, and the role of the government in addressing social issues. Doing so will prepare social work students and professionals to think and engage in a manner that will allow them to challenge and advocate for a change to the status quo. 相似文献

Clinical studies of children in international adoption reveal unique patterns of psychological adjustment to permanent family care. Pre‐adoption history often includes early object loss, medical and nutritional deprivation, multiple care‐giving disruptions, and the lack of primary care‐giving relationships. These factors and the age at the time of adoption are risks to positive emotional and cognitive development. Adoptive parents may be unprepared for the resulting developmental problems. Most significantly, parents and children are often at different points in readiness to establish an attachment relationship. The parents are eager to claim their child, but the child is unready to respond because of emotional fragility and lack of previous attachment experiences. Two clinical vignettes illustrate the importance of a developmental and medical framework in assessing the unique needs of these survivor children, as well as the necessity of an empathic therapeutic holding environment that can sustain the emerging family attachments under stress. The psychological impact of cross‐cultural adoption and traumatic early beginnings reverberates across time but with empathic parental care and treatment recovery can be significant. 相似文献

ABSTRACT African American adolescents continue to be disproportionately impacted by HIV, sexually transmitted infections (STIs), and unanticipated pregnancies. In-depth, face-to-face interviews among a convenience sample of 32 African American adolescents (16 male and 16 female) were used to explore the reasons why some adolescents decided to engage in sex while others chose to delay sexual debut. Data were analyzed using a thematic analysis. Among the overall sample, psychological motivations, external pressure, physical pleasure seeking, and relationship-related motivations were the major themes cited for engaging in sex by participants and their friends. External support, motivation to avoid negative consequences, not feeling ready or lacking interest in sex, and having negative views about sex were among the major reasons for delaying sex. Several of the emergent themes showed gender differences. Suggestions for future research include the need for sexual education, and STI/HIV prevention programs that are gender sensitive and flexible enough to accommodate multiple factors related to sexual debut. 相似文献

Abstract The authors examined a proposed profile of eating-related behaviors, associated features, developmental issues, and help-seeking behavior among college women, using an eating disorder response program. The most common symptom scenario was a pattern of regular binge eating, together with daily exercise and occasional purging. The most common associated features were distressing or dysfunctional overconcern about body image and self-esteem, usually with day-to-day stress and intermittent depression. The women who fit this pattern also presented developmental issues of perfectionism, conflictual relationships with parents, and struggles for independence; and they tended to be ambivalent about seeking services. Implications for practice, including the need to develop a framework for eating disorder responses on campus that includes preventive programs and developmental interventions to target emerging and moderate concerns are discussed; limitations and the preliminary nature of the findings are explicated. 相似文献

We present a new method for deriving the stationary distribution of an ergodic Markov process of G/M/1-type in continuous-time, by deriving and making use of a new representation for each element of the rate matrices contained in these distributions. This method can also be modified to derive the Laplace transform of each transition function associated with Markov processes of G/M/1-type. 相似文献

Alcohol consumption and its relationship to gambling was examined in a statewide New Mexico survey in 1996 and 1998. Data
regarding both drinking habits and gambling behavior were obtained from a stratified random sample of the adult population
(N = 2674) across the entire State of New Mexico via phone survey. These surveys were carried out shortly after a period when
New Mexico experienced an initial surge in the legalized gaming industry. Fifty-seven percent of survey respondents reported
drinking in the past month, while 43.1% reported no drinking in the past 30 days. Results show that while the number of days
in the past 30 that a person drinks is significantly correlated with some types of gambling behavior (e.g., in 1998, drinking
more days was associated with more card gambling and sports gambling), it is the amount of alcohol consumed per occasion that
is associated with more gambling behavior. For example, in both 1996 and 1998, drinking more per occasion was associated with
more sports betting, dice gambling, number/lottery gambling, gambling using machines, and paper game gambling (e.g., pull
tabs, punchboard). These results suggest that problem gambling behavior is not affected as much by the number of occasions
on which one consumes alcohol, as by the amount of alcohol consumed per occasion. 相似文献
