Parent–adolescent conflict poses risk for youth maladjustment. One potential mechanism of this risk is that stress in the form of increased arousal during conflict interactions results in adolescents’ impaired decision-making. However, eliciting consistent adolescent stress responses within laboratory-based tasks of parent–adolescent conflict (i.e., conflict discussion tasks) is hindered by task design. This limitation may stem from how conflict topics are assessed and selected for discussion. Within a sample of 47 adolescents (ages 14–17) and parents, we investigated whether a modified version of a conflict discussion task could elicit physiological (i.e., arousal) and behavioral (i.e., hostility) displays of adolescents’ conflict-related stress responses. We assessed parent–adolescent conflict via structured interview to identify topics for dyads to discuss during the task. We randomly assigned dyads to complete a 5-min task to discuss either a putatively benign topic (i.e., control condition) or a conflict topic while undergoing direct assessments of continuous arousal. Trained raters coded dyad members’ hostile behavior during the task. Adolescents in the conflict condition exhibited significantly greater levels of arousal than adolescents in the control condition. We observed an interaction between discussion condition and baseline conflict. Specifically, higher baseline conflict predicted greater hostile behavior for adolescents in the conflict condition, yet we observed the inverse relation for adolescents in the control condition. Our modified laboratory discussion task successfully elicited both physiological and behavioral displays of adolescent conflict-related stress. These findings have important implications for leveraging experimental paradigms to understand causal links between parent–adolescent conflict and adolescent psychopathology, and their underlying mechanisms.  相似文献

A great deal of research has investigated weight as a predictor for bullying victimization. However, weight is rarely examined in light of its potential role in explaining bullying perpetration, despite the fact that the definition of bullying typically requires a power imbalance, which can refer to either social power or physical size. Using negative binomial regressions, we investigated weight as a predictor of overt and relational bullying behaviors for a sample of 3208 6th–8th graders from 11 schools in a northeastern state. We examined whether this relationship differs by gender, and we explored whether objective size or perception of size is more predictive of perpetration. We also examined whether certain protective factors, like a positive school environment, moderated the effect of weight on bullying perpetration. We found that students who reported a higher BMI engaged in more overt, but not relational, bullying perpetration. Interestingly, students with misperceptions about their weight reported higher levels of both types of bullying perpetration, while students reporting a more positive school climate engaged in less overt and relational bullying. We also found gender differences in that girls are statistically more likely to commit overt bullying if they have a higher BMI. Our results suggest that prevention programs should address weight as a predictor of bullying behaviors, especially for girls, but also that body image and misperception of weight are important topics for prevention programs.  相似文献

Previous research on the treatment of pica (i.e., the ingestion of inedible objects) is limited compared to research on the treatment of other types of severe problem behavior. This study involved the use of differential reinforcement of alternative behavior, with a discard response as the alternative behavior, to treat pica presented by a 13‐year‐old girl with an autism spectrum disorder. We extended previous research by thinning the schedule of reinforcement for the alternative response. Substantial reductions in pica were obtained. Limitations and future directions in the treatment of pica are discussed.  相似文献

Living in disorganized neighborhoods characterized by high levels of poverty, crime, violence, and deteriorating buildings has been associated with increased alcohol consumption and mental health problems. Data drawn from the Seattle Social Development Project (N = 790), a theory‐driven longitudinal study originating in Seattle, WA, were used to estimate trajectories of Alcohol Use Disorder (AUD) symptoms from age 21 to 39. Time‐varying measures of neighborhood disorganization, psychological distress, and sociodemographic factors were associated with deviations from average AUD symptoms at each wave. Results indicated that, on average, AUD symptoms decreased as individuals got older. Living in more disorganized neighborhoods and experiencing psychological distress was associated with increased AUD symptoms after accounting for average reductions from AUD symptoms over time and time‐varying measures of relevant sociodemographic factors. Results of mediation analysis suggested that psychological distress is a mechanism by which disorganized neighborhoods increased risk of AUD from age 21 to 39.  相似文献

Despite the large body of literature investigating drug use, limited research has explored both the individual and structural dimensions of drug use, and an even smaller number of studies have focused on drug use in the Asian context. The current study draws on self-reported survey data on marijuana, methamphetamine, and opium use among offenders in South Korea. We apply four major theoretical perspectives to understand predictors of drug use in this context. Results demonstrate the link between methamphetamine use and unemployment and find strong predictability of social learning variables. Limitations and implications of the current study are discussed.  相似文献

Electronic data collection and participant pool management tools give researchers new ways to conduct research. The current study investigated the equivalency of in-person and online administrations of the Right-Wing Authoritarianism, Social Dominance Orientation, and Modern Racism scales across three modalities (administration in person, online through Sona Systems, and online through Mechanical Turk). Results indicate that in-person administration was largely equivalent to the randomly assigned online sample (Sona Systems) in terms of their intercorrelations, mean scores, variability, and reliability. However, the Sona sample consistently responded with strong attitudes for all measures, suggesting that social desirability may be decreased when completing these measures online. In addition, the Mechanical Turk sample differed in many ways from both in-person and Sona administration; although this nonequivalence is at least partially explained by sample demographic differences, other considerations may have exacerbated nonequivalence, including prior exposure to the measures and a desire to respond correctly.  相似文献

Online comprehension of naturally spoken and perceptually degraded words was assessed in 95 children ages 12 to 31 months. The time course of word recognition was measured by monitoring eye movements as children looked at pictures while listening to familiar target words presented in unaltered, time-compressed, and low-pass-filtered forms. Success in word recognition varied with age and level of vocabulary development, and with the perceptual integrity of the word. Recognition was best overall for unaltered words, lower for time-compressed words, and significantly lower in low-pass-filtered words. Reaction times were fastest in compressed, followed by unaltered and filtered words. Results showed that children were able to recognize familiar words in challenging conditions and that productive vocabulary size was more sensitive than chronological age as a predictor of children's accuracy and speed in word recognition.  相似文献

The AMA Council on Ethical and Judicial Affairs (CEJA) has written a position paper on how social medical use challenges medical professionalism. The report offers persuasive ethical and practical guidelines for nonclinical internet use, specifically for social networking. This commentary provides a framework from which to apply these guidelines, but adds that there may be important situations in which physicians are not able to act in accordance. The guidelines call for professional reporting of questionable online portrayals or behaviors, but this commentary argues that this may be not only cumbersome to implement, but may violate aspects of constitutional rights. While online social networking may in many ways be a new application of old challenges, there may be other aspects that require novel approaches to medical professionalism.  相似文献

Intentions have been shown to be more accessible (e.g., more quickly and accurately recalled) compared to other sorts of to-be-remembered information; a result termed an intention superiority effect (Goschke & Kuhl, 1993). In the current study, we demonstrate an intention interference effect (IIE) in which color-naming performance in a Stroop task was slower for words belonging to an intention that participants had to remember to carry out (Do-the-Task condition) versus an intention that did not have to be executed (Ignore-the-Task condition). In previous work (e.g., Cohen et al., 2005), having a prospective intention in mind was confounded with carrying a memory load. In Experiment 1, we added a digit-retention task to control for effects of cognitive load. In Experiment 2, we eliminated the memory confound in a new way, by comparing intention-related and control words within each trial. Results from both Experiments 1 and 2 revealed an IIE suggesting that interference is very specific to the intention, not just to a memory load.  相似文献
