领导者底线心智对团队创新的双刃剑效应

底线心智是一种以获取底线利润结果为中心,而忽略其他一切竞争事项优先权(如企业社会责任、利益相关者权益、员工福利等)的单维思维模式。虽然底线心智可能导致管理者只注重绩效而忽视其他对企业有利的重要事项,甚至采取不道德的手段来实现目标,但研究也表明底线心智能够提高员工工作专注度进而提升绩效。为进一步推进底线心智双刃剑效应的研究,本文构建了领导者底线心智对团队创新双刃剑效应的影响机制模型,指出领导者底线心智一方面抑制了团队风险承担意愿,进而相比于探索式创新更有益于利用式创新;另一方面能够激发团队强迫激情,从而相比于团队创意产生更有利于团队创意实施。本文为深化底线心智领域的研究提供了参考,也为组织和领导者如何更好管理底线心智提供了重要建议。     

半个多世纪来中国人的心理与行为变化——心理学视野下的研究

半个多世纪以来, 史无前例的快速社会变迁对中国文化和中国人的心理与行为产生了广泛而深远的影响。现有研究探讨了中国人在十多个方面的心理和行为变化, 包括文化价值、人格特征、自我建构、人际信任、幸福感、情绪、动机、关系、心理健康以及其他社会态度和行为等。总体上, 这些研究勾画出了半个世纪以来中国人心理变化的总体倾向：(1)与现代社会相适应的个体主义价值和心理行为日益盛行; (2)传统社会所强调的集体主义价值虽日渐衰落, 但其部分仍在当代社会主流价值中占有一席之地; (3)多元文化共存将是当下和未来中国社会的重要特征。一些具体的变化还包括：中国人的一般信任在下降、幸福感先下降但近年来有上升的迹象、心理健康总体水平上升但是不同社会群体升降不一致、总体的负性情绪在增加、性观念更为开放和包容等。未来的研究应在广度(内容、领域)和深度(原因、机制和过程)上对现有研究进行拓展, 努力建构能同时解释心理和行为变化一般规律及中国人的变化独特性的理论。     

睾酮素与反社会倾向未成年犯的攻击行为：敌意注意偏向的中介和皮质醇的调节作用

为考察睾酮素与反社会倾向未成年犯攻击行为的关系,在整合攻击行为生物激素视角和社会认知视角的基础上,探究敌意注意偏向的中介作用与皮质醇的调节作用。对84名未成年犯的激素水平、敌意注意偏向以及攻击行为进行调查。结果显示：(1)敌意注意偏向(注意不稳定性、注意回避)在睾酮素对攻击行为的影响中起完全中介作用;(2)皮质醇调节睾酮素与敌意注意偏向的关系,仅在高皮质醇水平下,敌意注意偏向的中介效应显著。基于生物激素影响攻击行为的中介机制和调节机制,可尝试从增加对敌意刺激的注意回避和提高皮质醇水平两个方面对反社会倾向未成年犯的攻击暴力行为进行干预。     

高中生感知教师支持与学习投入的关系:学业自我效能感和成就目标定向的链式中介作用

采用感知教师支持、学习投入、学业自我效能感和成就目标定向问卷对498名高中生进行问卷调查,探讨感知教师支持对学习投入的影响,以及学业自我效能感和成就目标定向的链式中介效应。结果显示：（1）感知教师支持能通过学业自我效能感间接预测高中生学习投入,感知教师支持可以通过掌握趋近、表现趋近、表现回避间接预测高中生学习投入;（2）学业自我效能感→掌握趋近、学业自我效能感→表现趋近、学业自我效能感→表现回避三者分别在感知教师支持与学习投入之间起链式中介作用,学业自我效能感→掌握回避的中介效应则不显著。上述结果表明,感知教师支持不仅能分别通过学业自我效能感、掌握趋近、表现趋近、表现回避预测高中生学习投入,还能通过学业自我效能感和成就目标定向的链式中介作用间接预测高中生学习投入。     

创造性问题解决中的联想能力及其作用

长期以来,研究者一直认为联想能力与创造力之间存在着紧密的联系,但相关的实证研究并不能很好地支持这一论断,这可能是由于联想能力的界定不清所造成的。本研究梳理了以往研究中联想能力与创造力的关系,在此基础上辨析了联想能力测验所反映的实质,进一步提出了一个创造性问题解决中联想能力的作用模型：（1）联想能力主要作用于创造性问题解决中的重构阶段;（2）存在三种相对独立的联想能力,它们对空间类顿悟问题和言语类顿悟问题的影响不同;（3）联想内容中经验关系的联想能力与领域一般创造力关联最密切。     

Effects of neonatal cyproterone acetate administration on isolation-induced fighting behavior and mounting behavior in male and female TO strain albino mice

The effects of a single dose (1 mg) of cyproterone acetate administered on either day 1 or day 20 of life on the adult behaviors of male and female TO strain albino mice were studied. The mice were tested both in a “standard opponent”-type situation and in a similar test using a hormonally primed receptive female, after being gonadectomized and maintained with testosterone propionate as adults. Neonatal treatment with this compound had little effect on subsequent fighting behavior in either sex, but clear evidence was produced that this treatment masculinized the sexual behavioral potentialities of the females, an effect which was apparent in animals which had been injected on either day 1 or day 20 of life. Indications were obtained that females treated neonatally with cyproterone acetate were capable of differentiating between the male and female “opponents” in a manner similar to the male. The effects of this treatment on fighting behavior consequently appear to be dissimilar to the effects of neonatal castration in this species. However, the effects on mounting behavior in the females, evidenced in adulthood, seem Likely to be a consequence of the weak androgenic properties of the antiandrogen. The administration of cyproterone acetate neonatally appears to have a more dramatic effect on the adult weights of endocrine organs in females than in mates.     

The role of endocrines in isolation-induced intermale fighting in albino laboratory mice. I: PITUITARY-ADRENOCORTICAL INFLUENCES

Recent experiments concerning the possible role of components of the pituitary–adrenocortical axis (ACTH and glucocorticoids) in isolation-induced intermale fighting behavior in laboratory strains of mice are reviewed. A series of experiments which investigate factors that may influence the successful demonstration of this relationship are described. Differences in performances in standard-opponent tests of some outbred strains of albino mice are indicated, as well as an interesting positive correlation between the aggressiveness and the relative adrenal weights of the strains employed. Long-acting preparations of both ACTH and ACTH 4–10, injected throughout a period of isolation, suppressed fighting behavior in intact TO-strain mice in subsequent standard-opponent and trained-fighter tests. After it had been confirmed that vigorous isolation-induced fighting could be obtained in bilaterally castrated mice which had been subcutaneously implanted with testosterone pellets, the effects of long-acting preparations of ACTH, ACTH 4–10, ACTH 1–10, and ACTH 4–10 D-phe on the fighting behavior of such animals were studied. A significant suppression of fighting behavior was evident only with respect to ACTH, suggesting that ACTH 4–10 may have its action on this behavior in a manner rather different from that of the parent molecule. Some evidence was also obtained indicating that the zinc used in the preparation of long-acting injections of ACTH and its analogs may also cause a decline in the level of fighting behavior, in a standard-opponent test, in TO-strain mice which had been castrated and testosterone implanted. While such a finding does not affect the validity of the recorded behavioral influences of ACTH and ACTH 4–10 described earlier, it does seem likely that the presence of this substance in placebo injections would make the demonstration of the actions of the pep tides difficult, as there would be a low level of fighting in all categories. Rather less impressive results were obtained with respect to the influences of ACTH preparations and zinc on castrated—implanted CFW mice. The studies identify a number of the factors which may influence the successful demonstration of a relationship between the functioning of the pituitary—adrenocortical axis and isolation-induced agonistic behavior in the mouse. A number of general, if tentative, conclusions may also be listed. It seems likely, in spite of the interpretational difficulties caused by what seems to be a complex and rather unstable relationship, that ACTH and glucocorticoids may have profound influences on this type of fighting behavior in this species. One may also conclude that the evidence for an extraadrenal influence of ACTH on this behavior appears stronger as a result of these and related studies and that the actions of ACTH and its analogs on murine fighting behavior may be logically related to the actions of these compounds on the acquisition and extinction of conditioned avoidance reactions in hypophysectomized rats. The possible utility of such actions to the natural territorial habit of the adult male mouse is also indicated.
