Attention-Deficit/Hyperactivity Disorder (ADHD) is a prime candidate for exploration of gene-by-environment interaction (i.e.,
G x E), particularly in relation to dopamine system genes, due to strong evidence that dopamine systems are dysregulated in
the disorder. Using a G x E design, we examined whether the DRD4 promoter 120-bp tandem repeat polymorphism, previously associated with ADHD, moderated the effects of inconsistent parenting
and marital conflict on ADHD or Oppositional-Defiant Disorder (ODD). Participants were 548 children with ADHD and non-ADHD
comparison children and their parents. Homozygosity for the DRD4 promoter 120-bp tandem repeat insertion allele increased vulnerability for ADHD and ODD only in the presence of inconsistent
parenting and appeared to increase susceptibility to the influence of increased child self-blame for marital conflict on ADHD
inattention. DRD4 genotypes may interact with these proximal family environmental risk factors by increasing the individual’s responsivity
to environmental contingencies. 相似文献

Previous research has found that drinking establishments are often antecedent to sexual aggression outcomes. In this study, male participants were randomly selected from public houses (i.e., "pubs") and asked to imagine themselves in a hypothetical intimate encounter in which the female in the scenario stops consenting to sexual contact. Participants were given the option to continue making sexual advances up to and including sexual intercourse against the woman's will. It was hypothesized based on Alcohol Myopia Theory that participant blood alcohol concentration (BAC) levels would be associated with hypothetical sexual aggression when stereotypical cues of a woman's sexual availability (revealing clothing and alcohol use) were present in the scenario. Men's engagement in hypothetical sexual aggression was associated with BAC levels, but only when the woman was wearing revealing clothing. The sobriety of the female actor was not associated with sexual aggression. Results indicate that Alcohol Myopia Theory generalizes to a field setting. 相似文献

Extending the simultaneous-sequential paradigm to measure perceptual capacity for features and words
Scharff A Palmer J Moore CM 《Journal of experimental psychology. Human perception and performance》2011,37(3):813-833
In perception, divided attention refers to conditions in which multiple stimuli are relevant to an observer. To measure the effect of divided attention in terms of perceptual capacity, we introduce an extension of the simultaneous-sequential paradigm. The extension makes predictions for fixed-capacity models as well as for unlimited-capacity models. We apply this paradigm to two example tasks, contrast discrimination and word categorization, and find dramatically different effects of divided attention. Contrast discrimination has unlimited capacity, consistent with independent, parallel processing. Word categorization has a nearly fixed capacity, consistent with either serial processing or fixed-capacity, parallel processing. We argue that these measures of perceptual capacity rely on relatively few assumptions compared to most alternative measures. 相似文献

The present study reveals that Election Day differentially affects the color preferences of US Republicans and Democrats. Voters’ preferences for Republican red and Democratic blue were assessed, along with several distractor colors, on and around the 2010 interim and 2012 presidential elections. On non-Election Days, Republicans and Democrats preferred Republican red equally, and Republicans actually preferred Democratic blue more than Democrats did. On Election Day, however, Republicans’ and Democrats’ color preferences changed to become more closely aligned with their own party’s colors. Republicans liked Republican red more than Democrats did, and no longer preferred Democratic blue more than Democrats did. These results are consistent with the hypothesis that color preferences are determined by people’s preferences for correspondingly colored objects/entities (Palmer & Schloss in Proceedings of the National Academy of Sciences 107:8877–8882, 2010). They further suggest that color preferences are calculated at a given moment, depending on which color–object associations are currently most activated or salient. Color preferences are thus far more dynamic and context-dependent than has previously been believed. 相似文献

Two studies tested the hypothesis that SWB predicts unique variance in academic citizenship attitudes, even while accounting for personality traits. In Study 1, participants (n?=?2,566) completed an online questionnaire assessing their positive and negative affect, ACBs and personality. The results indicated that positive affect predicted consideration, civic virtue, and conscientiousness, whereas negative affect predicted citizenship conscientiousness and sportsmanship while controlling for personality. In Study 2, participants (n?=?260) completed measures of life satisfaction, ACBs and personality. The results showed that life satisfaction predicted all ACBs while controlling for personality. Based on these results, it can be concluded that SWB is an important predictor of ACBs. Implications for the selection of student aids in academic settings are discussed. 相似文献

One Woman's Development and Resilience in the Face of Complex Trauma: A Relational–Cultural Study of Growth Through Counseling 下载免费PDF全文
Molly Stehn 《Adultspan: Theory Research & Practice》2014,13(2):120-128
Many counselors feel pressure to use manualized treatment approaches because of pressure from 3rd‐party payers. Unfortunately, this is not always the best practice, especially in cases of complex trauma, in which a very strong therapeutic relationship is a vital component of successful treatment. Relational–cultural theory provides an alternative conceptual lens for treating complex cases and is a natural fit for counselors' professional identity. This case illustrates how a counselor used a relational–cultural conceptualization as a guide in treating a client with complex presenting concerns. 相似文献

Teaching college students to pour accurately using behavioral skills training: Evaluation of the effects of peer modeling 下载免费PDF全文
Excessive alcohol consumption among college students is a serious problem. Alcohol education courses, during which students are taught to free‐pour accurate servings of alcohol, have been proposed as one strategy to reduce this problem. However, few studies have evaluated the effects of peer models on free‐pour skill maintenance. We used a nonconcurrent multiple‐baseline across subjects design to assess the effects of peer modeling on maintenance of college students' (N = 19) pouring skills of a standard serving of beer immediately following Behavioral Skills Training (BST). Results indicated participants who inaccurately poured a standard serving of beer at baseline (n = 17) accurately poured following receipt of BST, and all participants (N = 19) maintained accurate pouring in the presence of peer confederate models who poured inaccurately or accurately. Results suggest BST is an efficient (i.e., low to no‐cost, requires no sophisticated laboratory space or software, and makes use of available and affordable materials) and effective tool for teaching college students to pour standard servings of beer and that the immediate introduction of inaccurately pouring peer models has little or no effect on skill maintenance. 相似文献
