动态范式中基于客体的返回抑制 ——是客体抑制还是空间抑制的动态更新？

对动态范式中基于客体的返回抑制进行了考察。实验1在双侧客体改变和不改变条件下考察了返回抑制效应,结果表明,在双侧客体改变条件下返回抑制仍然存在。实验2采用单侧客体变化技术对动态范式中基于客体的返回抑制进行了测量,结果发现,在有效线索化条件下,单侧客体改变和不改变条件下对靶子的反应时没有显著差异（p > 0.90）。这些结果表明动态范式中基于客体的返回抑制的机制是空间抑制的动态更新,而不是客体表征受到抑制     

知识图式对贝叶斯推理的影响

选取具有概率知识的大学生(专家)和没有概率知识的大学生(新手)为被试,进行贝叶斯推理中的概率估计,探讨知识图式对贝叶斯推理的影响。结果表明,具有概率知识背景的大学生比没有概率知识背景的大学生概率估计的准确性更高,反应时更长,说明知识图式影响概率信息的搜索和判断。     

Entrepreneurship,professionalism, leadership: A framework and measure for understanding boundaryless careers

We propose a person-centered framework for conceptualizing subjective careers in an increasingly boundaryless work context. Specifically, we argue that entrepreneurship, professionalism, and leadership (EPL) can serve as three key dimensions of subjective career space. We relate this framework to earlier macro-level national and organizational career models proposed by Kanter (1989) and Schein (1978). Our empirical study involving 10,326 Singaporean university students demonstrated that entrepreneurial, professional, and leadership career aspirations (including motivations, efficacies, and intentions) can be measured independently, that these career dimensions are independent of vocational interests, and that they are to some degree viewed as competing career alternatives. We also show that EPL motivation profiles can operationalize the boundaryless and protean career concepts. Individuals concurrently high in entrepreneurial, professional, and leadership career motivations, and those high in entrepreneurial and leadership motivations are highest in boundaryless and self-directed career attitudes, while those primarily motivated for professional careers hold the most traditional career attitudes. We conclude by discussing the potential of the framework for understanding human resource issues at organizational and national levels and for enhancing the study of entrepreneurship, professionalism, and leadership.

A confirmatory factor analytic approach on perceptions of knowledge and skills in teaching (PKST)

This paper reports the cross-validation of the factor pattern of the Perceptions of Knowledge and Skills in Teaching (PKST) survey, which was used to assess the self-perceived pedagogical knowledge and skills of pre-service and beginning teachers. The sample comprised 323 pre-service teachers enrolled in a 1-yr. post-graduate teacher education program in Singapore. The survey had 37 items distributed across six scales: student learning, lesson planning, instructional support, accommodating diversity, classroom management, and care and concern. A confirmatory factor analysis (CFA) was used to cross-validate the survey's factor pattern. The results showed that the model was an acceptable fit to the data. The PKST survey can thus be adapted by different teacher education programs to assess pre-service and beginning teachers' progress in developing their pedagogical knowledge and skills.     

Collaborative partner or social tool? New evidence for young children’s understanding of joint intentions in collaborative activities

Some children’s social activities are structured by joint goals. In previous research, the criterion used to determine this was relatively weak: if the partner stopped interacting, did the child attempt to re‐engage her? But re‐engagement attempts could easily result from the child simply realizing that she needs the partner to reach her own goal in the activity (social tool explanation). In two experiments, 21‐ and 27‐month‐old children interacted with an adult in games in which they either did or did not physically need the partner to reach a concrete goal. Moreover, when the partner stopped interacting, she did so because she was either unwilling to continue (breaking off from the joint goal) or unable to continue (presumably still maintaining the joint goal). Children of both age groups encouraged the recalcitrant partner equally often whether she was or was not physically needed for goal attainment. In addition, they did so more often when the partner was unable to continue than when she was unwilling to continue. These findings suggest that young children do not just view their collaborative partners as mindless social tools, but rather as intentional, cooperative agents with whom they must coordinate intentional states.     

Military training and personality trait development: does the military make the man, or does the man make the military?

Military experience is an important turning point in a person's life and, consequently, is associated with important life outcomes. Using a large longitudinal sample of German males, we examined whether personality traits played a role during this period. Results indicated that personality traits prospectively predicted the decision to enter the military. People lower in agreeableness, neuroticism, and openness to experience during high school were more likely to enter the military after graduation. In addition, military training was associated with changes in personality. Compared with a control group, military recruits had lower levels of agreeableness after training. These levels persisted 5 years after training, even after participants entered college or the labor market. This study is one of the first to identify life experiences associated with changes in personality traits. Moreover, our results suggest that military experiences may have a long-lasting influence on individual-level characteristics.     

无意识信息加工中的“完型”——无意识捆绑假说的新证据

采用连续闪烁范式(Continuous Flash Suppression,CFS)考察了无意识状态下完型能否发生.研究通过2(线条完整性)×2(意义破坏)×2(熟悉性)的被试内实验设计考察了8种条件下图片的突破抑制时间(Suppression Time,ST).结果发现:线条完整和意义未破坏的图片能更快地克服噪音图片的抑制进入意识;熟悉性不影响突破抑制时间.重要的是,不完整的图片也可以出现意义破坏效应.这表明即使在被抑制的状态下,不完整图形的信息也能够传达至与完型相关的高级视觉区域形成客体表征.研究为无意识捆绑假说(The Unconscious Binding Hypothesis)提供了新的实验证据.     

Attachment dynamics in a virtual world

The study investigated the transfer of attachment working models onto autonomous agents in a virtual social environment (VSE). Participants from a community sample (N = 422; mean age = 29 years; mean relationship duration = 4.8 years) encountered three attachment‐related key scenes in a VSE: a separation with a subsequent reunion, a conflict, and an illness. In these scenarios, participants gave instructions to the main character (the “protagonist”), who had a romantic relationship with one of the other agents (the “virtual spouse”). Recorded were numerous behaviors as well as emotions participants ascribed to the protagonist. Generally, participants' attachment styles correlated as predicted with their behavior toward the virtual spouse, with βs up to.42. Thus, the study demonstrates that internal working models are transferred to the virtual relationship. This approach opens new ways to investigate attachment‐related behavior by using VSEs that allow experimental variations of the virtual partner's reactions and other situational variables.
