环境条件和兴趣对大学生妥协决策的影响

研究旨在考察个体在选择职业时是否会为了更好的环境条件(组织、城市)而降低对兴趣的要求。对63名大学生被试开展了两个实验,采用在环境条件和兴趣水平上有不同程度差异的职位配对来模拟两难决策。结果发现:(1)对不同组织声望和兴趣水平的职位的选择无性别差异;(2)组织声望差距、组织声望差距与兴趣差距的交互作用能显著预测职位的选择;(3)对不同城市级别和兴趣水平的职位的选择有性别差异,男生比女生更少放弃兴趣;(4)兴趣差距、城市级别差距与兴趣差距的交互作用能预测男生的选择,只有兴趣差距能预测女生的选择。结论:个体会为了更好的环境而或多或少在兴趣方面妥协。     

词素认知加工的理论模型及研究范式

自上世纪七十年代以来,随着视觉词汇加工领域的研究,多词素词的认知加工引起了研究者的广泛关注。文章对三十年来的研究进行综述和系统梳理,重点讨论词素在多词素词认知加工中的作用。虽然对词素加工的本质 (形或义的激活)仍未达成共识,但词素语义能否在多词素词加工的早期阶段得到激活已成为现今研究的焦点问题之一。相关研究大致可分为三个对立阶段：分解论与整体论之争、词素形式论与语义论之争、先形后义激活论与形义同时激活论之争。本文最后指出该研究领域尚未解决的问题并对未来研究进行了展望。     

组织心理所有权、基于组织的自尊对积极组织行为的影响

采用自编的组织心理所有权、基于组织的自尊和积极组织行为等有效量表调查45家生产型企业共2566名员工,以检测组织心理所有权、基于组织的自尊对积极组织行为的影响。结果发现组织心理所有权、基于组织的自尊和积极组织行为之间有显著的正相关,组织心理所有权、基于组织的自尊对积极组织行为有显著正向预测作用,其中基于组织的自尊在组织心理所有权与积极组织行为之间起显著的部分中介作用。尤其是对组织及个人声誉或成就的心理所有权感对员工积极组织行为各个因素有显著正预测作用,基于组织的自尊在投入行为、主动行为和谋取人际和谐行为上影响效应更为显著。这意味着增强员工组织心理所有权感,培育员工主人翁意识和组织归属感,重视基于组织的自尊,提升员工的组织价值感和自豪感等措施有利于提升企业组织和个体绩效。     

抑郁症状阳性人群的初始沙盘特征

采用病例对照研究设计,探讨抑郁症状阳性人群初始沙盘特征。结果显示：抑郁症状阳性组在总数、动物、人物、建筑物、交通工具、植物类沙具使用少于对照组;抑郁症状阳性组沙盘空间领域使用少于对照组;抑郁症状阳性组在从哪里开始、对沙的态度、有无蓝色露底、是否使用桥、自己感觉是否满意、自我像是否在其中和主题场景上与对照组比较差异有统计学意义;沙盘主题特征回归分析显示进入抑郁症状阳性回归方程的沙盘主题特征变量有忽视、威胁、流动和能量。抑郁症状阳性人群在沙盘游戏中有特征性表现,初始沙盘具有临床心理评估的功能和价值。     

Reception of Morse code through motional, vibrotactile, and auditory stimulation

The potential for communication through the kinesthetic aspect of the tactual sense was examined in a series of experiments employing Morse code signals. Experienced and inexperienced Morse code operators were trained to identify Morse code signals that were delivered as sequences of motional stimulation through up-down displacements (roughly 10 mm) of the fingertip. Performance on this task was compared with that obtained for both vibrotactile and acoustic presentation of Morse code using a 200-Hz tone delivered either to the fingertip through a minishaker or diotically to the two ears under headphones. For all three modalities, the ability to receive Morse code was examined as a function of presentation rate for tasks including identification of single letters, random three-letter sequences, common words, and sentences. Equivalent word-rate measures (i.e., product of percent correct scores and stimulus presentation rate) were nearly twice as high for auditory presentation as for vibrotactile stimulation, which in turn was about 1.3 times that for motional stimulation. The experienced subjects outperformed the inexperienced subjects by amounts that increased with task complexity. For example, the former were able to receive sentences at 18 words/min with motional stimulation, whereas the latter, following 75 h of training, were unable to perform this task. The present results and those of other research with tactual communication systems are compared, particularly regarding estimates of information-transfer rates.     

Global-local processing impacts academic risk taking

Research has shown that academic risk taking—the selection of school tasks with varying difficulty levels—affords important implications for educational outcomes. In two experiments, we explored the role of cognitive processes—specifically, global versus local processing styles—in students’ academic risk-taking tendencies. Participants first read a short passage, which provided the context for their subsequent academic risk-taking decisions. Following which, participants undertook the Navon’s task and attended to either global letters or local letters only, i.e., were either globally or locally primed. The effects of priming on academic risk taking were then assessed using a perception-based measure (Experiment 1) and a task-based measure (Experiment 2). Experiment 1 provided preliminary evidence, which Experiment 2 confirmed, that globally focused individuals took more academic risk than did locally focused individuals after controlling for participants’ need for cognition (how much they enjoy effortful cognitive activities). Additionally, the inclusion of and comparisons with a control group in Experiment 2 revealed that locally focused participants drove the observed effects. The theory of predictive and reactive control systems (PARCS) provides a cogent account of our findings. Future directions and practical applications in education are discussed.     

Psychological and Sociocultural Adaptation of Children Adopted from Russia and their Associations with Pre-Adoption Risk Factors and Parenting

We investigated academic and behavioral outcomes of internationally adopted children and the associations between these outcomes and age at adoption, time spent in the adoptive family, and parenting. At two time points (T1 and T2, ~15 months apart), we examined early academic skills (school readiness), and parent-reported behavioral adjustment (internalizing and externalizing behavior) and adaptive functioning of a sample of 75 children (45.9% boys, mean age?=?5.17 years) adopted from Russia into US families. We also collected parents’ self-assessments of their parenting at T1. Children who were adopted at a younger age showed higher levels of early academic skills. Correlations between age at adoption and other outcomes were overall small and mostly non-significant. However, adoptees’ academic and behavioral progress differed notably in several respects. Specifically, adoptees improved in early academic skills over time, whereas, as a group, their adaptive functioning and behavioral adjustment remained stable within the normal range. Early academic skills were not related to behavioral adjustment at each time point and over time. The time spent in the adoptive family was positively related to early academic skills at T2. Whereas outcomes showed little to no relation to parenting as reported by mother and father separately, higher discrepancies between mothers' and fathers' reports of positive parenting were related to higher levels of behavioral symptoms and lower levels of adaptive skills at T2. These differential results may be explained in part by drawing upon the notion of dissociated domains of psychological and sociocultural adaptation and acculturation, outlined in the immigration literature. These results also bring to light the possible importance of between-parent consistency in parenting for adoptees’ behavioral outcomes.     

顿悟问题解决不同阶段中工作记忆的作用

该研究探讨了顿悟问题解决不同阶段中工作记忆的作用。在实验1中,以87名大学生为被试,使用多种工作记忆广度任务和言语顿悟任务,探讨了工作记忆对于言语顿悟问题解决不同阶段的影响;在实验2中,以119名大学生为被试,使用多种工作记忆广度任务和空间顿悟任务,探讨了工作记忆对于空间顿悟问题解决不同阶段的影响。研究结果表明,初始搜索阶段与重构阶段是相对独立的两个阶段;工作记忆对于顿悟问题解决的不同阶段有着不同的影响,它主要影响顿悟问题解决的初始搜索阶段,工作记忆能力越强,初始搜索阶段所需时间越少;工作记忆对于顿悟问题解决的重构阶段无显著影响,这一点支持了关于重构内在机制的特殊过程观。
