A systematic review of published and unpublished English language articles identified 14 studies containing 18 comparisons between functional family therapy (FFT) and another condition in the treatment of adolescent disruptive behavior and substance use disorders. In 11 of these comparisons, assignment to conditions was random, while nonrandom assignment occurred in seven studies. For both random and nonrandom comparisons, separate meta‐analyses were conducted for subgroups of studies depending on the type of comparison group used. Data from studies of untreated control groups (CTL), treatment as usual (TAU), and well‐defined alternative treatments (ALTs) were analyzed separately. Effect sizes from these six meta‐analyses were as follows: random assignment FFT versus CTL (k = 3, d = 0.48, p < .01); random assignment FFT versus TAU (k = 3, d = .20, ns); random assignment FFT versus ALT (k = 5, d = .35, p < .05); nonrandom assignment FFT versus CTL (k = 2, d = .90, ns); nonrandom assignment FFT versus TAU (k = 2, d = .08, ns); and nonrandom assignment FFT versus ALT (k = 3, d = .75, p < .001). These results provide support for the effectiveness of FFT compared with untreated controls and well‐defined ALTs, such as cognitive behavior therapy, other models of family therapy, and individual and group therapy for adolescents. 相似文献

为探讨应变率显像(SRI)技术评价尿毒症左心室射血分数(EF)正常患者左心室局部功能的价值,对41例尿毒症EF正常患者及20例健康自愿者左心室心肌纵向SRI曲线进行分析,测量各曲线收缩峰值应变率(SRs)、舒张早期峰值应变率(SRe)、舒张晚期峰值应变率(SRa)并计算SRe/SRa。结果显示,尿毒症组左心室各节段SRs、SRe、SRe/SRa均低于对照组(P0.05)。因此,尿毒症EF正常患者已经存在局部心肌舒缩功能障碍,并且这种障碍可以被SRI技术敏感、定量地评价。 相似文献

Ethics and Intuitions 总被引:1,自引:0,他引:1

For millennia, philosophers have speculated about the origins of ethics. Recent research in evolutionary psychology and the
neurosciences has shed light on that question. But this research also has normative significance. A standard way of arguing
against a normative ethical theory is to show that in some circumstances the theory leads to judgments that are contrary to
our common moral intuitions. If, however, these moral intuitions are the biological residue of our evolutionary history, it
is not clear why we should regard them as having any normative force. Research in the neurosciences should therefore lead
us to reconsider the role of intuitions in normative ethics. 相似文献

A study was conducted to examine the hypothesis that matching (vs. mismatching) the source of a persuasive message to the functional basis of recipients’ attitudes may lead to positively biased processing. Under conditions conducive to effortful processing, high and low self-monitors were presented with a persuasive message ascribed to a source that either matched or mismatched the functional basis of their attitudes (i.e., an expert source for low self-monitors and an attractive source for high self-monitors). The message content was either unambiguous strong, unambiguous weak, or ambiguous. As predicted, given an ambiguous message biased processing led to more agreement when the source matched (vs. mismatched) attitude functions. In contrast, an unambiguous strong message led to more agreement than an unambiguous weak message regardless of source matching (unbiased processing). Results are discussed with respect to the role of the activation and use of heuristics in biased processing. 相似文献

While a substantial body of research has investigated the effects of aerobic exercise on cognitive performance, few have monitored exercise‐concurrent cognitive processes via electroencephalography and fewer still using an event‐related potential (ERP) approach. As such, little is known regarding how the temporal dynamics of cognitive processing are influenced during aerobic activity. Here, we aimed to elucidate the influence of aerobic exercise on the temporal dynamics of concurrent visual working memory (VWM) performance. Participants performed a VWM retro‐cue task at rest and during aerobic exercise across two postural modalities: seated (using a stationary bicycle) and standing upright (using a treadmill). Three consecutive phases of the VWM processing pipeline were assessed by means of lateralized ERPs: access of VWM representations, response selection, and response execution. Aerobic exercise and upright posture were found to have significant effects on VWM performance, facilitating processing speed in the retro‐cue task. This facilitation arose primarily at an intermediary stage between the phases of accessing VWM representations and response selection. Our findings hold implications not only for understanding the influence of aerobic activity on VWM, but also for contemporary models of VWM that are built exclusively on data recorded during stationary, seated conditions. 相似文献

Paired muscle stimulation is used clinically to facilitate the performance of motor tasks for individuals with motor dysfunction. However, the optimal temporal relationship between stimuli for enhancing movement remains unknown. We hypothesized that synchronous, muscle stimulation would increase the extent to which stimulated muscles are concurrently prepared for movement. We validated a measure of muscle-specific changes in corticomotor excitability prior to movement. We used this measure to examine the preparation of the first dorsal interosseous (FDI), abductor digiti minimi (ADM), abductor pollicis brevis (APB) muscles prior to voluntary muscle contractions before and after paired muscle stimulation at four interstimulus intervals (0, 5, 10, and 75 ms). Paired muscle stimulation increased premovement excitability in the stimulated FDI, but not in the ADM muscle. Interstimulus interval was not a significant factor in determining efficacy of the protocol. Paired stimulation, therefore, did not result in a functional association being formed between the stimulated muscles. Somatosensory potentials evoked by the muscle stimuli were small compared to those commonly elicited by stimulation of peripheral nerves, suggesting that the lack of functional association formation between muscles may be due to the small magnitude of afferent volleys from the stimulated muscles, particularly the ADM, reaching the cortex. 相似文献

Parent-infant interactions are one of the most critical and enduring aspects of infants’ experience. Qualities of parent-infant interactions are related to social-emotional and cognitive developmental outcomes, yet how parent-infant interactions shape the functional organization of the brain is only beginning to be understood. Functional connectivity provides information about how brain regions communicate. Patterns of functional connectivity, thus far understudied in infants, have emerged as markers of abnormalities in the organization of the brain in at-risk infants as well as individuals with neurodevelopmetnal and neurodegenerative disorders. The current study sought to inform our understanding of relations between qualities of parent-infant interactions and functional connectivity. We report relations between responsiveness, reciprocity, and emotional tone and functional connectivity in theta, alpha, beta, and gamma in infants ranging from 6 to 11 month of age (N = 51). Results showed frontal-posterior connectivity in theta was inversely related to all three dimensions of parent-infant interactions. Gamma and alpha connectivity were positively associated with responsiveness and emotional tone, respectively. Results are discussed in the context of the experience-dependent nature of brain development, emphasizing how parent-infant interactions might be leveraged to structure early organization of the brain to foster healthy social-emotional and cognitive developmental outcomes. 相似文献

自尊稳定性(自尊在短期内波动的幅度)是一种具有重要心理功能的人格特质, 它既不同于自尊水平, 也区别于情境性自尊, 但在理论和测量上却与后两者具有密不可分的联系。然而, 由于目前人们对于自尊稳定性的认知神经机制知之甚少, 所以并不清楚它与自尊水平在生理机制上的关系是什么, 更不了解它会如何调节情境性自尊。鉴于此, 本研究计划将自尊稳定性、自尊水平和情境性自尊置于整合的认知神经加工模型(神经内分泌-脑-行为)之中, 通过融合心理测量、脑成像与应激诱发等多种技术指标, 力争全方位、多角度揭示自尊稳定性的认知神经机制, 及其与自尊水平、情境性自尊间的区别和联系。 相似文献

不同类型的体育锻炼对各种群体的多种认知功能均具有促进作用, 而相关的生理机制也在不同水平得到研究。在微观水平, 体育锻炼有利于脑细胞的营养供给和能量代谢, 并且能促进神经元的存活和突触生成。在宏观水平, 体育锻炼不仅能够提升海马和小脑等脑结构的体积, 还影响脑区激活水平和脑区间功能连接。值得注意的是, 体育锻炼对认知的促进效应受到诸多因素的影响, 比如个体差异、时间, 以及体育锻炼和认知刺激的相互作用等, 这些影响因素也为在两个水平上系统地阐明体育锻炼促进认知的脑机制提供了新的视角。 相似文献
