家庭支持型主管行为与双职工夫妻的婚姻满意感:一个积极溢出-交叉模型

为了揭示家庭支持型主管行为(FSSB)对双职工夫妻双方婚姻满意感的影响及作用机制,本研究结合资源-获取-发展观和基于关系支持的积极发展模型,从夫妻互动(相互支持)的角度构建了一个积极溢出-交叉模型。运用结构方程模型对370对双职工夫妻配对数据进行分析,结果表明:(1)FSSB与我国双职工夫妻双方的婚姻满意感均正相关;(2)FSSB可通过增加员工的工作-家庭增益促进员工夫妻间相互支持的互惠效应,进而提升员工夫妻双方的婚姻满意感;(3)夫妻双方所获得的FSSB均可通过促进丈夫的婚姻满意感进而提升妻子的婚姻满意感。本研究提示,增加FSSB能有效促进双职工夫妻间的相互支持、提升夫妻双方的婚姻满意感。     

冰毒使用者抑制控制的损伤、可逆性及干预策略

冰毒使用的危害日益凸显,受到社会的普遍关注。行为、认知和脑功能的研究结果一致表明:长期的冰毒使用会导致使用者的抑制控制受损,包含一般抑制控制损伤以及药物相关线索条件下的损伤。这些损伤与前额脑区的异常密切相关,对冰毒使用者的行为和认知能力产生不良影响。目前,这些损伤只能部分恢复,因此,改善冰毒使用者抑制控制的干预策略成为热点。未来研究可以从不同药物成瘾者的差异性、多药物使用模式以及有区别的运动干预等方面对冰毒使用者的抑制控制损伤进行深入研究。     

CS-dependent response probability in an auditory masked-detection task: considerations based on models of Pavlovian conditioning.

Experimental studies were performed using a Pavlovian-conditioned eyeblink response to measure detection of a variable-sound-level tone (T) in a fixed-sound-level masking noise (N) in rabbits. Results showed an increase in the asymptotic probability of conditioned responses (CRs) to the reinforced TN trials and a decrease in the asymptotic rate of eyeblink responses to the non-reinforced N presentations as a function of the sound level of the T. These observations are consistent with expected behaviour in an auditory masked detection task, but they are not consistent with predictions from a traditional application of the Rescorla-Wagner or Pearce models of associative learning. To implement these models, one typically considers only the actual stimuli and reinforcement on each trial. We found that by considering perceptual interactions and concepts from signal detection theory, these models could predict the CS dependence on the sound level of the T. In these alternative implementations, the animals response probabilities were used as a guide in making assumptions about the "effective stimuli".     

Rasmussen's syndrome: intractable epilepsy and progressive neurological deterioration from a unilateral central nervous system

Rasmussen's syndrome (chronic encephalitis with epilepsy) is a rare neurological disorder of unknown cause characterized by severe epilepsy, hemiplegia, dementia, and inflammation of the brain, and progressive functional and structural destruction of a single cerebral hemisphere. While one mechanism underlying the pathogenesis of Rasmussen's encephalitis has been hypothesized to be mediated by production of excitotoxic GluR3 autoantibodies to the a-amino-3-hydroxy-5-methylisoxazole-4-propionic acid (AMPA) receptor, other neuropathological etiologies have also been indicated. Proposed therapies have included antiepileptics, steroids, antiviral agents, alpha-interferon, and immunoglobulin. The mainstay of therapy is surgical hemispherectomy. To date, no medical therapies have permanently halted neurologic deterioration.     

复合伤的"复合效应"中线性与非线性的辩证关系

复合伤的“复合效应”是非线性观在医学研究领域中的一个范例。它不仅具有重要的实际价值,而且具有较高的理论意义。复合伤效应不是单纯的“加重效应”,而是“复合效应”,即可加重,不加重,以至减轻。复合伤的复合效应规律的基本特征和本质是非线性特征,而复合效应中线性与非线性特征的关系是辩证统一的。     

基于文本阅读的间接接触也可改善公众对残疾人的态度

以镶嵌残疾人图片的正性行为描述性信息为文本阅读材料,以大学生为被试,采用概念启动范式,考察了健全人对残疾人态度改善的可能性.研究结果表明,阅读残疾人正性行为描述性材料不仅可以降低健全人对残疾人的负性认知评价,而且可以提高其对残疾人的钦佩感和减弱其对残疾人的嫌弃感,同时也可提高健全人对该类人群的积极趋近行为和减弱对该类人群的消极趋近和消极回避行为,从而证明基于文本阅读的间接接触可改善公众对残疾人的负性态度的假设.因此,创造条件鼓励残疾人尽力发挥其积极的社会功能,引导和塑造其身残志不残的品质,有助于改善健全人对该类人群的消极态度.     

Learning More About and With the Face–Name Mnemonic Strategy

With the face–name mnemonic strategy, choosing and using ‘prominent’ facial features in interactive images can be difficult. The temptation is to stray from less‐than‐distinctive facial features and instead to associate an individual's name clue with an additional concrete detail (e.g., a headband). To examine this issue, undergraduates viewed face photographs with or without additional details under one of three conditions: own best method, fully imposed mnemonic, and partially imposed mnemonic. Experiment 2 examined a somewhat parallel situation that occurs when applying the strategy to abstract artwork (paintings with less familiar, less concrete elements) versus applying it to representational artwork (paintings with more familiar concrete elements). Our findings suggest that some pictorial stimuli (e.g., facial photos with details; representational paintings) are easier to work with mnemonically than are others (e.g., facial photos by themselves; abstract art). Moreover, in both experiments, mnemonic students displayed performance advantages on both immediate and delayed tests. Copyright © 2014 John Wiley & Sons, Ltd.
