A large body of research has documented a relation between the executive cognitive functions (ECFs) and interpersonal aggressive behavior. A predominant theory proposes that individuals with poor ECFs are more aggressive because they are unable to inhibit impulsive behaviors. However, evidence for this relationship is typically indirect. In this study, 46 healthy men and women completed measures of ECF, the Taylor Aggression Paradigm, and the Go/No‐Go discrimination task, a behavioral measure of impulsivity. Also, impulsiveness of participant responses during the aggression task was directly assessed by measuring latency of responses to provocation (“set‐time”). It was hypothesized that low‐quartile–scoring ECF men and women would perform more aggressively and more impulsively than high‐quartile peers. Consistent with expectations, results indicated that ECF was related to aggression and to impulsivity on the Go/No‐Go task. However, low‐ECF men and women did not have shorter set‐times; in fact, on this task, low‐ECF participants' behavioral decisions seemed slightly slower than those of high‐ECF participants. In light of these results, the authors speculate that a social information‐processing problem may mediate the ECF aggression relationship rather than altered impulsivity per se. Aggr.

许多研究显示, 冲动性与尼古丁、可卡因、海洛因等药物成瘾显著相关, 但它对吗啡成瘾的影响尚未见到报道。本实验考察冲动性对吗啡诱导的条件性位置偏爱及行为敏感化的影响。实验采用延迟奖赏模型将大鼠的冲动性区分为高、中、低三个水平, 每个水平设置吗啡处理组和盐水处理组。结果发现:动物对吗啡诱导的条件性位置偏爱的程度表现为低冲动组>中冲动组>高冲动组, 并且中、低冲动组动物形成了条件性位置偏爱而高冲动组没有形成这种偏爱; 在行为敏感化表达期, 与相应的盐水组比较, 高、中冲动组动物的吗啡运动激活效应显著, 而低冲动组没有达到显著水平。这些结果提示, 条件性位置偏爱任务中, 动物的冲动性越高, 吗啡的强化效应越低; 行为敏感化任务中, 动物的冲动性越高, 吗啡的运动激活效应越高。由此可见, 动物的冲动性对吗啡诱导的条件性位置偏爱及行为敏感化的影响存在差异。 相似文献

This paper analyzes the results of an 18 month study of a variety of participants involved in written reflection on their learning, both in classes at two universities in the Southern US or in voluntary focus groups. The purpose of the study was to analyze the effects of including autobiographical tools in written reflection. Participants used three tools from the genre of autobiography as they reflected on their learning inside either course content, internship experiences, experiential learning, or goal-setting. Over 500 samples were gathered, offering a large data set for analysis of what kinds of best practice produce quality reflective writing. Through analysis of the data and student surveys and interviews, results show increased attention to critical thinking and metacognition; expressed flexibility, adaptability, and ability to handle ambiguity; and value in connection to others/empathy-building as a result of incorporating autobiographical tools in reflective prompts. The study indicated that reflections using the same autobiographical tool over the course of several sessions seemed to produce deeper levels of reflection and more engagement with the autobiographical tool. Of the three autobiographical tools used in the study, the tool that seemed most helpful to participants was reflection as storytelling that revealed aspects of the self. 相似文献

Socially prescribed perfectionism (SPP) is often considered as a key risk factor for disordered eating (DE). However, current conceptualizations of SPP largely assume that this perfectionism pressure is non‐specific (i.e., a global pressure), despite research indicating that for females experiencing DE, female‐dominated groups impose this pressure (as a perceived norm). Furthermore, this relationship may be mediated by a negative reaction to this pressure, in the form of impulsivity (or negative urgency). To date, no research has investigated whether the relationship between SPP and DE is mediated by negative urgency, nor has there been research clarifying how in‐group identification relates to DE, independent of SPP and negative urgency. To address these gaps, we assessed these variables in 147 female dieters (Mage = 25.12 years, SD = 3.08) using a cross‐sectional design. Consistent with our hypotheses, negative urgency fully mediated the link between female‐based SPP and disordered eating, while female‐based in‐group affect (identification) was predictive of disordered eating (although the latter relationship was not sustained in a multiple regression model). These findings suggest that the SPP from other women may relate to DE through increasing negative urgency, and that the link between in‐group (female) affect and DE may be better explained by SPP's link to DE. 相似文献

This paper offers two new arguments for a version of Reflection, the principle that says, roughly, that if one knew now what
one would believe in the future, one ought to believe it now. The most prominent existing argument for the principle is the
coherence-based Dutch Strategy argument advanced by Bas van Fraassen (and others). My two arguments are quite different. The
first is a truth-based argument. On the basis of two substantive premises, that people’s beliefs generally get better over
time and that being a person requires having knowledge of this fact, it concludes that it is rational to treat your future
selves as experts. The second argument is a transcendental one. Being a person requires being able to engage in plans and
projects. But these cannot be meaningfully undertaken unless one has Reflection-like expectations about one’s future beliefs.
Hence, satisfaction of Reflection is necessary for being a person. Together, the arguments show that satisfaction of Reflection
is both rational and necessary for persons.

Three participants with moderate to profound mental retardation were exposed to choices between an immediate small amount and a delayed larger amount of a preferred reinforcer. All participants initially showed a relatively high preference for the smaller reinforcer, suggesting impulsive choice making. However this preference reversed, suggesting self-control, when the larger reinforcer was available immediately and, over time, its delay was gradually increased. Results highlight the potential utility of incorporating concurrent activities into self-control training paradigms. 相似文献

Individuals draw on a variety of cognitive strategies—some active, some passive—as a way of coping with stress and dysphoria. Previous research suggests that the impact of rumination—one such strategy—on depression depends on whether rumination takes the passive form of brooding versus the more active form of reflection. This study tests whether brooding and reflection explain the effects of passive versus active coping responses, respectively, on depressive symptoms. In an undergraduate sample (n=284), brooding partially mediated the relationship between passive coping and depressive symptoms, whereas reflection did not. Reflection moderated the relationship between active coping and symptoms, such that low active copers who were high in reflection endorsed more symptoms than those low in reflection. Brooding and reflection may operate within cognitive–behavioural response pathways characterised by an active/passive distinction. Whether reflection is maladaptive likely depends on the active nature of the surrounding coping response. 相似文献

This study examined the extent to which rumination and depression share genetic and environmental influences in a community sample of adult twins (N = 663). Twins completed multiple rumination questionnaires, a depressive symptoms questionnaire and a diagnostic interview. Rumination was moderately heritable (h2 = .37–.41 for the latent variable) and substantially influenced by nonshared environmental factors, and these results were consistent across different measures. Nonshared environmental influences on rumination were larger for women than men. Depressive symptoms and diagnosis were influenced by genetic and nonshared environmental factors (h2 = .30–.45). The genetic correlations between rumination and depression were moderate to large (rA = .40–.82), suggesting that a substantial proportion of the genetic influences on rumination overlap with those on depression. Results were similar when examining self-reported depressive symptoms and interview-based diagnosis of major depressive disorder. These results highlight the importance of rumination in the integration of cognitive and genetic models of depression risk. 相似文献

In this pilot study, differences in inattention, impulsivity, and hyperactivity as well as demographic factors were investigated in a community sample of 8- through 11-year-olds, approximately half of whom had experienced child abuse or neglect. Parents completed the Attention Deficit Hyperactivity Disorder Test, the SNAP-IV, the Brief Betrayal Trauma Survey – Parent version, and additional questions. Abused children had more severe impulsivity and inattention, but not hyperactivity, symptoms. Abused boys and girls had a similar age of onset of symptoms, whereas nonabused girls had a much later age of onset than nonabused boys. ADHD is a significant problem among maltreated children. These data support large scale studies investigating possible differences in etiology, presentation, and treatment. 相似文献
