Grammatical Aspect in Early Child Mandarin: Evidence from a Preferential Looking Experiment

The study assessed 30-month-old Mandarin-speaking children’s awareness of aspectual distinctions involving the perfective marker le and the imperfective marker zhe in a preferential looking experiment. In the experiment, we presented our child subjects with a choice between two video clips (one depicting a closed event and the other depicting an on-going event), in the presence of an auditory stimulus (either the le sentence, the zhe sentence or the control sentence without any aspect marker). Children’s looking behavior in the task was recorded and analyzed. The results revealed 30-month-old children’s emerging sensitivity to the aspectual contrast between le and zhe. This was manifest by an increase in looking to the closed event when hearing the le sentence and an increase in looking to the on-going event when hearing the zhe sentence. The absence of le or zhe in the control sentence did not result in any increase or decrease in looking to either event. We also found that the effect of le on children’s looking behavior was immediate whereas the effect of zhe was late. We attributed this difference to the facilitative role of le in children’s sentence processing as well as their preference for the event boundary. The results lend support to the continuity view that functional morphemes like aspect markers are available to children early in language development.     

Multiple attentional control settings at distinct locations without the confounding of repetition priming

An attentional control setting (ACS), which is based on the task goal, induces involuntary attentional capture by a stimulus possessing a target-defining feature. It is unclear whether ACSs are maintained for multiple targets defined as conjunctions of a color and location. In the present study we examined the possibility of local ACSs for dual targets defined as combinations of color and location, using different paradigms: visual search in Experiment 1, and spatial cueing in Experiment 2. In Experiment 1, a distractor captured attention only when its features matched the ACSs. Likewise, in Experiment 2, a significant attentional capture effect was found only with a matching cue, whose color and location were in line with the conjunction of the target definition. Importantly, the identical pattern of attentional capture was also obtained for a neutral-color target, which was unlikely to be primed by any color of the cue. Thus, these findings imply that the attentional bias depending on the match between the cue and target did not result from cue–target repetition priming. The present study highlights that top-down attentional control can be set flexibly to accomplish a complex task goal efficiently.     

Balance,Proprioception, and Gross Motor Development of Chinese Children Aged 3 to 6 Years

The authors' aim was to find the features of balance, proprioception, and gross motor development of Chinese children 3–6 years old and their correlations, provide theoretical support for promoting children's motor development, and enrich the world theoretical system of motor development. This study used a Tekscan foot pressure measurement instrument (Tekscan, Inc., Boston, MA), walking on a balance beam, Xsens 3-dimensional positional measuring system (Xsens Technologies, Enschede, the Netherlands), and Test of Gross Motor Development-2 to assess static balance, dynamic balance, knee proprioception, and levels of gross motor development (GMD) of 3- to 6-year-old children (n = 60) in Beijing. The results are as follows: children had significant age differences in static balance, dynamic balance, proprioception, and levels of GMD; children had significant gender differences in static balance, proprioception, and levels of GMD; children's static balance, dynamic balance, and proprioception had a very significant positive correlation with GMD (p < .01), but no significant correlation with body mass index.     

A Systematic Comparison of African American and Non-African American Patients on Psychosocial Aspects of Hepatitis C Infection

The purpose of this study was to compare African American and non-African American hepatitis C virus (HCV) patients on self-reported symptoms of HCV liver disease and psychosocial characteristics commonly affected by it in a sample of 309 patients enrolled in a randomized controlled trial. African Americans (n = 196) rated a higher reliance on religion/spirituality for coping with HCV compared to non-African Americans. This study’s findings are a basis for encouragement of public health efforts and programs to seek partnerships with African American faith and religious communities to identify and treat undiagnosed cases of HCV and promote HCV awareness.     

大学生的冲动性特质与自杀意念的关系:一个有调节的中介模型

以应激-易感模型为依据考察冲动性特质与自杀意念的关系,并在此基础上提出一个有调节的中介模型,探讨负性生活事件影响的中介作用以及家庭环境的调节作用。采用巴瑞特冲动性量表、青少年生活事件量表、家庭环境量表、贝克自杀意念量表对902名大学生进行集体施测,旨在考察负性生活事件的影响对大学生冲动性特质与自杀意念的中介作用以及家庭环境的调节作用,结果表明:(1)冲动性特质和负性生活事件的影响能正向预测大学生的自杀意念;(2)负性生活事件的影响在冲动性特质和自杀意念之间起中介作用;(3)负性生活事件影响的中介作用和冲动性特质的直接作用受家庭环境的调节。这些结果对于综合解释环境与个体因素对自杀意念的作用与机制具有重要意义。     

No evidence for unethical amnesia for imagined actions: A failed replication and extension

In a recent study, Kouchaki and Gino (2016) suggest that memory for unethical actions is impaired, regardless of whether such actions are real or imagined. However, as we argue in the current study, their claim that people develop “unethical amnesia” confuses two distinct and dissociable memory deficits: one affecting the phenomenology of remembering and another affecting memory accuracy. To further investigate whether unethical amnesia affects memory accuracy, we conducted three studies exploring unethical amnesia for imagined ethical violations. The first study (N = 228) attempts to directly replicate the only study from Kouchaki and Gino (2016) that includes a measure of memory accuracy. The second study (N = 232) attempts again to replicate these accuracy effects from Kouchaki and Gino (2016), while including several additional variables meant to potentially help in finding the effect. The third study (N = 228) is an attempted conceptual replication using the same paradigm as Kouchaki and Gino (2016), but with a new vignette describing a different moral violation. We did not find an unethical amnesia effect involving memory accuracy in any of our three studies. These results cast doubt upon the claim that memory accuracy is impaired for imagined unethical actions. Suggestions for further ways to study memory for moral and immoral actions are discussed.     

Dynamic Creative Interaction Networks and Team Creativity Evolution: A Longitudinal Study

To assess the dynamical effects of creative interaction networks on team creativity evolution, this paper elaborates a theoretical framework that links the key elements of creative interaction networks, including node, edge and network structure, to creativity in teams. The process of team creativity evolution is divided into four phases, including formation, growth, maturity and decline/restart. The importance of domain‐relevant knowledge, creativity‐relevant skill, interaction frequency, interaction length, network density and closeness centrality are emphasized in specific phases of team creativity evolution in a complex creative context. To test our assumptions, a longitudinal study of creative teams in a “Challenge Cup” Creative Business Plan Competition for university students is performed and the full networks of 17 creative entrepreneur teams are mapped. Both static comparison and dynamic analysis are conducted to analyze the relationship between creative interaction networks and team creativity evolution. For specific phases of team creativity evolution, we find confirmation of our predictions. The implications of dynamic creative interaction networks for all the phases of creative teams from formation to decline/restart are discussed.     

选择与坚持:跨期选择与延迟满足之比较

做出选择与坚持选择是决策活动的两个重要阶段。跨期选择源于经济学领域对成人对发生在不同时间点的结果"做出选择"过程的研究;延迟满足则源于心理学领域对儿童为获得未来较大收益而抵制当前诱惑的"坚持选择"过程的研究。二者均致力于研究与时间相关的决策活动,从不同视角关注个体的冲动性与自我控制,但鲜见学者对二者异同的系统比较。本文着重从研究方法、认知机制与神经基础入手探讨了二者的异同,冀为两个研究领域协同发展、共同促进人类远见的培养与实践提供科学的理论支持。     

德行领导与员工不道德行为、利他行为:道德推脱的中介作用

以道德推脱理论为基础,运用问卷调查法,通过对776名员工的调查,探讨了德行领导对员工不道德行为和利他行为的影响及道德推脱在这一影响中的中介作用。研究发现:(1)德行领导会抑制员工不道德行为的产生、促进员工利他行为的出现;(2)道德推脱会促进员工不道德行为的产生、抑制员工利他行为的出现;(3)德行领导通过道德推脱的完全中介作用负向影响员工的不道德行为,通过道德推脱的部分中介作用正向影响员工的利他行为。
