信息过少容易使人成为井底之蛙, 不利于做出高质量的决策; 那拥有更多信息是否就能做出更高质量、有远见的决策呢?已有研究发现海量信息导致注意资源稀缺, 注意资源对跨期决策至关重要, 但海量信息如何影响跨期决策的内在机制尚不明确。本研究基于注意资源的理论视角提出:海量信息加剧注意资源的稀缺, 一方面当前信息捕获过多注意资源, 导致指向未来的注意资源减少, 造成模拟未来不清晰、预测未来不准确, 意图形成减少; 另一方面增加对时间紧迫性的关注, 减少为长远未来做计划的意愿, 导致在跨期权衡中更偏好近期选项。长期导向的特质可以使个体将注意聚焦于长远收益, 做出更有远见的决策。研究结果将科学地解释海量信息影响跨期决策的内在机制, 并为进一步探讨助推海量信息环境下有远见的跨期决策提供理论与实证依据。 相似文献

Psychodiagnostic testing is being belabored by behavioristic psychologists for being a poor predictor of behavior and by humanistic psychologists for being a discriminatory procedure. It is also being alleged that psychodiagnosis serves little purpose, is tied to an anachronistic model of diagnosis, and is no longer being used or taught to any great extent. These criticisms are refuted by a clarification of the role psychodiagnostic assessment serves in personality appraisal, and survey data are adduced to indicate that psychodiagnosis is very much alive and well in contemporary clinical psychology. 相似文献

Background
Low birth weight and low 5-min Apgar scores have been associated with developmental delay, while older maternal age is a protective factor. Little is known about trajectories and predictors of developmental skills in infant twins, who are generally born with lower birth weights, lower Apgar scores and to older mothers.Methods
Developmental skills were assessed at 3, 6, 9, 12, 18 and 24 months using the Ages and Stages Questionnaires in 152 twins from the Birmingham Registry for Twin and Heritability Studies. Multilevel spline and linear regression models (adjusted for gestational age, gender, maternal age) were used to estimate developmental trajectories and the associations between birth weight, maternal age and Apgar scores on developmental skills.Results
Twins performed worse than singletons on communication, gross motor, fine motor, problem solving and personal-social skills (p < 0.001). Twins caught up around 6 months (score within −1 standard deviation of norm), except on gross motor skills, which did not catch up until after the age of 12 months. A one-year increase in maternal age was significantly associated with decreases in gross motor and personal–social z-scores of up to −0.09, whereas one unit increases in Apgar score increased z-scores up to 0.90 (p < 0.01).Conclusions
Healthy twins should be considered at a higher risk for developmental delay. Whether these results are comparable to preterm singletons, or whether there are twin-specific issues involved, should be further investigated in a study that uses a matched singleton control group. 相似文献295.

We introduced facial electromyography as a tool for predicting advantaged group members' engagement in antidiscrimination action on behalf of a disadvantaged outgroup. Heterosexual men's corrugator supercilii (brow “frowning” muscles) activity while viewing videos of male–male and male–female couples interacting was measured. Corrugator (negative affect) response to male–male versus male–female targets, but not self-reported attitudes toward gay men, predicted number of flyers calling for action to reduce antigay violence and discrimination that participants privately took to distribute. Our discreet behavioral measure mirrored real-life collective action possibilities such as voting against laws prohibiting same-sex marriage in the privacy of one's voting booth. 相似文献

An extensive body of literature has documented executive function (EF) impairments in children with fetal alcohol spectrum disorders (FASD); however, few studies have aimed specifically at improving EF. One treatment program that shows promise for children with FASD is the Alert Program for Self-Regulation®, which is a 12-week treatment specifically designed to target self-regulation, a component of EF. The present study sought to examine if Alert would produce improvements in self-regulation that would generalize to other aspects of EF, behavior, and social skills in children with FASD. Twenty-five children aged 8–12 years diagnosed with an FASD were assigned in alternating sequence to either an immediate treatment (TXT) or a delayed treatment control (DTC) group. Both groups received a comprehensive evaluation of EF at baseline and upon completing therapy (TXT), or after a 12- to 14-week interval from baseline (DTC). Parents also completed questionnaires assessing EF and behavior at both time points. For the TXT group only, parent questionnaires were readministered at 6-month follow-up. At the 12-week follow-up, the TXT group displayed significant improvements in inhibitory control and social cognition. Parents of children in the TXT group reported improved behavioral and emotional regulation, as well as reduced externalizing behavior problems. These behavioral improvements along with further improved parent-rated inhibitory control was maintained at the 6-month follow-up. The EF disabilities in children with FASD can be remediated through a targeted treatment approach aimed at facilitating self-regulation skills. 相似文献

Individual social differences have been addressed in recent studies, and the oxytocin receptor gene (OXTR) is the major candidate in explaining various social phenotypes. To study the association between a well-known haplotype (rs53576) of OXTR and children's prosocial behavior and its relationship with theory of mind (ToM) ability, 87 children (aged 3 to 5 years old) participated in 3 prosocial tasks and ToM performance experiments. Participants who were homozygous for the G allele (GG) exhibited more prosocial behaviors than did those with 1 or 2 copies of the A allele (AA), and GG carriers also displayed better ToM ability than did AA individuals. Further tests showed differences between genotypes in helping and comforting, albeit not in sharing. The results demonstrated that OXTR rs53576 was related to individual differences in ToM and was associated with prosocial behavior. 相似文献

药物成瘾会导致相关神经环路的结构和功能长期改变.大量新的研究证据表明,在DNA序列不变的情况下,药物成瘾可通过影响不同亚型DNA甲基转移酶(DNMTs)的表达,使脑内多个相关核团发生DNA甲基化以及基因表达的改变,进而导致神经元功能的可塑性变化.因此,DNA甲基化被视作导致成瘾行为长期存在的可能机制之一.结合近几年来的重要发现,本文将重点讨论相关脑区的DNA甲基化在成瘾行为发生发展过程中的作用,以及成瘾药物影响DNA甲基化水平的可能机制,并试图提出可深入的研究展望. 相似文献

了解医生护士对PICC告知态度。自设问卷调查北京市两所医院执行PICC操作科室医生护士。医生护士认为操作前应向患者告知并签署同意书,部分原因有统计学差异;临床主要采取“医生告知、护士实施”模式;双方均倾向于降低自身法律风险的告知模式,赞成国家出台护士进行特殊告知的法律文件。建议现阶段采取医护共同告知模式。 相似文献
