社会动机与“自我-他人”对创造性表现的影响

以往研究发现个体为自己和为他人的创造表现存在差异,但研究结论不一致。另外,考虑到社会动机是影响“自我-他人”表现的重要因素,本研究采用2（社会动机：亲社会、利己）×2（“自我-他人”：自我、他人）混合实验设计,考察社会动机与“自我-他人”如何来影响创造性表现。结果发现,亲社会组创造性表现的新颖性、有效性和总分均高于利己组,支持了动机性信息加工理论。自我组在创造性表现的新颖性和总分上高于他人组,这与解释水平理论的观点不一致。矛盾的原因可能是在东方“紧”文化背景下,人们按照社会认可的价值体系来为他人创造时,人们对新颖性的态度是谨慎的,因此为自我创造比为他人创造更加新颖。     

薪酬水平和薪酬差距对企业运营结果影响的元分析

以国内外113篇企业薪酬水平和薪酬差距领域的实证研究(254个效应值, 438880家企业)为样本, 采用基于结构方程模型的元分析方法检验了企业平均薪酬水平、垂直薪酬差距和水平薪酬差距对企业创新、绩效和离职等运营结果的影响。元分析结果显示, 平均薪酬水平不仅能够显著提升企业的创新和绩效水平, 也会抑制企业内部的离职水平; 垂直和水平薪酬差距对企业绩效的主效应并不显著, 但其对企业创新具有显著的抑制作用, 并能够显著提升企业的离职水平。进一步的调节效应检验表明, 国家地域因素调节了薪酬水平与企业绩效之间的关系, 即中国企业的平均薪酬水平对企业绩效的促进作用显著高于美国企业。研究结果对于企业的薪酬管理具有一定的借鉴意义。     

Detecting objects is easier than categorizing them

Two experiments compared performance in an object detection task, in which participants categorized photographs as objects and nonobject textures, and an object categorization task, in which photographs were categorized into basic-level categories. The basic-level categorization task was either easy (e.g., dogs vs. buses) or difficult (e.g., dogs vs. cats). Participants performed similarly in the detection and the easy-categorization tasks, but response times to the difficult-categorization task were slower. This latter finding is difficult to reconcile with the conclusions of Grill-Spector and Kanwisher (2005) who reported equivalent performance on detection and basic-level categorization tasks and took this as evidence that figure-ground segregation and basic-level categorization are mediated by the same mechanism.     

Impact of a System of Care on a Community's Children's Social Services System

Researchers and practitioners have questioned how the implementation of a system of care influences the broader context of children's social services within a community. We examined the impact that the Dawn Project system of care had on children's services in Marion County, Indiana. A series of semi-structured interviews were conducted in order to gain a broad understanding of stakeholder perspectives related to how system-level and other community leaders viewed system of care influences. Qualitative analyses uncovered several common themes including positive impact at the community level, challenges to implementation, and feelings of ambivalence related to program impact. Results were generally positive and suggested that most respondents saw core system of care principles beginning to emerge within the community related to the establishment of the care system. In addition, challenges to implementing the system of care also were uncovered, including some underlying resistance to system-level changes. Implications from our study highlight the importance of continuously working to enhance strengths and collaboration among systems, integrate and coordinate across systems and services, and authentically involve families at all levels.     

The social-encoding benefit in face recognition is generalized to other-race faces

Faces are visual stimuli that convey rich social information. Previous experiments found better recognition for faces that were evaluated based on their social traits than on their perceptual features during encoding. Here, we ask whether this social-encoding benefit in face recognition is also found for categories of faces that we have no previous social experience with, such as other-race faces. To answer this question, we first explored whether social and perceptual evaluations for other-race faces are consistent and valid. We then asked whether social evaluations during encoding improve recognition for other-race faces. Results show that social and perceptual evaluations of own- and other-race faces were valid. We also found high agreement in social and perceptual evaluations across individuals from different races. This indicates that evaluations of other-race faces are not random but meaningful. Furthermore, we found that social evaluations facilitated face recognition regardless of race, demonstrating a social-encoding benefit for both own- and other-race faces. Our findings highlight the role of social information in face recognition and show how it can be used to improve recognition of categories of faces that are hard to recognize due to lack of experience with them.     

Cocaine and food deprivation: effects on food-reinforced fixed-ratio performance in pigeons.

Key pecking by 6 pigeons was maintained by a fixed-ratio 30 schedule of food presentation while body weights were 80% of free-feeding weights. Acute administration of cocaine (0.3 to 13.0 mg/kg, i.m.) dose-dependently decreased response rates. Dose-effect curves were shifted to the right when 3 of the 6 pigeons were maintained at 70% of free-feeding weights and were shifted to the left when the other 3 pigeons were maintained at 90% of free-feeding weights. Then a dose of cocaine that initially decreased response rates by more than 95% of control rates was administered before each daily session. Comparable degrees of tolerance to these rate-decreasing effects developed in the two groups. The rate at which responding recovered was relatively rapid for pigeons in the 70% free-feeding-weight group and was slower for 2 of the 3 pigeons in the 90% free-feeding-weight group. When body weights were then increased from 70% to 80% or were decreased from 90% to 80% of free-feeding weight, performance was disrupted initially only for pigeons whose weight went from 70% to 80% of free feeding. In the present experiment the degree of deprivation may have indirectly influenced the degree of tolerance that developed to cocaine's response rate-decreasing effects because it directly influenced the dose chosen to be administered chronically. The degree of deprivation appeared to have a more direct influence on the rate at which tolerance developed.     

Genetic counseling for the next 25 years: Models for the future

Currently, two trends pose particular challenges for genetic counseling: (1) spin offs from the Human Genome Project leading to new diagnostic genetic tests far in advance of any cures; and (2) an increasing and diversified client population. These trends will lead to changes in both genetic service delivery systems and the development of alternative models of the genetic counseling process itself. Two models that could be adapted for genetic counseling are: the mutual participation model and the life history narrative model. Technological advances present ethical dilemmas and raise many questions. Already, improved detection of genes for predisposing conditions has entered clinical medicine requiring renewed ethical appraisals of genetic testing. Integration of genetic counseling (and required pre-screening education) into primary care settings involves time constraints and the involvement of health care personnel with less training in genetics. Alternative approaches are beginning to be discussed. Innovative genetic counselors with expanded visions of counseling goals and practices will play an increasingly important role in the future of genetic counseling.     

Evaluation of human consciousness level by means of “automated fluctuation analysis” of high frequency electroencephalogram fitted by double Lorentzians

Since Berger’s discovery of the electroencephalogram (EEG), its analysis has been generally restricted to the visual range (upmost 100Hz) and has ignored higher frequency components. One reason should be that there are no reliable methods to distinguish the brain potentials from muscle activity. We have introduced fluctuation analysis, which is popular method especially in the field of basic physiology to clinical electrophysiology. In our previous study, it was declared that power spectral density (PSD) of human high frequency EEG was composed of double Lorentzians and vanished into white level within 1kHz. Then the purpose of this study is to elucidate the “Automated Fluctuation Analysis,” which enables us to evaluate these higher frequency components and its physiological meaning especially focused on conscious level from wakefulness to sleep stage 1. Seventy-four scalp recording EEGs in twenty normal subjects were studied. In short, “Automated Fluctuation Analysis” is made of three steps: amplification of EEG signal, A/D conversion and Fast Fourier Transform by signal processor and extraction of Lorentzian parameters. PSD of high frequency EEG was displayed on log-log graph and the algorithm fit to the following Lorentzian formula were mathematically based on Brown & Dennis. S(f)=S1/ [1+(f/fc₁)²] + S2/ [1+(f/fc₂)²], where S(f) is PSD (μ V²/Hz) at each frequency (f;Hz), S1 and S2 are the plateau level or zero-frequency power of the initial and second Lorentz, and fc₁ and fc₂ are the corner or half-power frequency of the initial and second Lorentz, respectively. As results, during wakefulness the PSD of high frequency EEG activity was composed of double Lorentzian fluctuations and the power distribution of S1 value in topographical display was frontal dominant. This pattern of S1 value disappeared and S2 value became lower during sleepiness and the second Lorentz disappeared during sleep.     

未来时间距离对自我行为表征的影响：评价内容效价的作用

先前研究表明,对于自我行为,相对于近期过去,个体对远期过去正性行为的表征更倾向于特质性和抽象性,但对负性行为的表征未获得明确的类似效应（申之美等,2010）。本研究以特质性和行动性行为描述句子为实验材料,通过两个实验考察了未来时间距离对自我正性行为和负性行为的表征特征的影响,以进一步探讨评价内容的效价特性对于建构水平的心理距离效应的调节作用。实验结果发现,相对于近期未来,被试对远期未来自我的正性行为更倾向于抽象的特质性表征,但在负性行为上未获得类似效应。个体对未来自我行为的正性期待和负性回避倾向可能是自我行为表征缺乏距离效应的心理机制。
