Factors and processes in children's transitive deductions

Transitive tasks are important for understanding how children develop socio-cognitively. However, developmental research has been restricted largely to questions surrounding maturation. We asked 6-, 7- and 8-year-olds (N?=?117) to solve a composite of five different transitive tasks. Tasks included conditions asking about item-C (associated with the marked relation) in addition to the usual case of asking only about item-A (associated with the unmarked relation). Here, children found resolving item-C much easier than resolving item-A, a finding running counter to long-standing assumptions about transitive reasoning. Considering gender perhaps for the first time, boys exhibited higher transitive scores than girls overall. Finally, analysing in the context of one recent and well-specified theory of spatial transitive reasoning, we generated the prediction that reporting the full series should be easier than deducing any one item from that series. This prediction was not upheld. We discuss amendments necessary to accommodate all our earlier findings.     

Hyperdimensional Perspectives in Out-of-Body and Near-Death Experiences

Recent theories of modern physics predict that the universe has more dimensions than are apparent to us. Many near-death experiencers report the perception that there are more dimensions than we are commonly aware of. These two statements might be related. This article examines the possibility of additional dimensions (hyperdimensions), what they would seem like, and whether they seem to be described by the unusual visual perspectives found in out-of-body and near-death experience accounts. I examine some implications of a hyperdimensional model of the universe.     

At the Edge of Eternity's Shadows: Scaling the Fractal Continuum from Lower into Higher Space

In this paper, I elaborate the hyperspatial implications of the fractal-scaling scheme that I introduced previously. Four case examples where out-of-body experiencers reported heightened and amplified visual capacities are correlated with this explanatory model. Three of these cases are identified as including an additional hyperspace signifier, the reported capacity to see through solid and opaque physical obstructions. One of these cases included yet another hyperspace signifier, the reported capacity to pass through such obstructions. Additional evidence supportive of this thesis is drawn from the literature on ecstatic experience, including out-of-body, near-death, and other varieties of mystical or visionary experience, and from that on psychedelic experience. Yet other hyperspace signifiers reported by ecstatic voyagers are also considered, including sensations of seeing outward spherically in 360 degrees and of seeing on all sides of three-dimensional solids simultaneously.     

初中生网络欺负的发展趋势：道德推脱、观点采择与共情关注的作用

以496名初中生为研究对象, 对其网络欺负行为进行为期2年的4次追踪测试, 同时测试其道德推脱、观点采择与共情关注。采用潜变量增长模型探讨初中生网络欺负行为的发展轨迹, 并分析道德推脱、观点采择与共情关注的影响。结果发现, (1)在2年时间内, 初中生网络欺负行为呈显著下降趋势, 起始水平与下降速度有显著负相关; (2)道德推脱能显著正向预测初中生网络欺负行为的起始水平, 负向预测其下降趋势; (3)观点采择能够显著负向预测初中生网络欺负行为的起始水平, 正向预测其下降趋势。上述结果肯定了道德推脱与观点采择对初中生网络欺负发展轨迹的预测作用, 以网络情境支持了道德推脱理论, 部分支持了社会信息处理模型。     

未来思维与问题性网络使用的关联机制:基于网络模型的分析*

缺乏未来的远见与思考是问题性网络使用（problematic internet use, PIU）发生发展的重要原因之一。而未来思维与PIU的相互作用尚不清楚。研究使用网络分析方法探讨未来思维的认知（未来情景思维、未来自我连续性和延迟折扣）、情感（预期愉悦）和个体差异成分（时间洞察力）与PIU的相互作用,并采用模拟算法识别PIU的最佳干预靶点。通过对2685名被试调查分析后发现:（1）未来思维的认知和情感成分以及未来积极洞察力与PIU呈显著负相关。（2）时间洞察力是PIU的远端因素,而未来思维的认知与情感成分在两者之间起中介作用。（3）预期清晰性是预防PIU恶化的最佳干预靶点,而未来自我生动性是促使PIU改善的最佳干预靶点。研究结果对于理解PIU的心理机制和制定干预策略具有重要意义。     

教改对教师工作生活质量影响的跨文化比较研究

本研究采用跨文化教育协作组(CCCRE)编制的访谈问卷,采用结构化访谈方式,通过跨文化教育研究协作对9个国家513名教师进行访谈调查。本文着重探讨了教改的种类、起因和角色特征对教师工作生活质量的影响。结果表明:1)教改类型对教师人际关系和职业发展的变化有显著影响2)教改起因对教师的时间利用和职业发展有显著影响,并在时间利用上显示出文化上的差异。3)我国教改在起因上表现出与总体趋同态势,但它们对教师的人际关系和职业发展的变化有更积极的影响。4)执行者是教师在教改中的主要角色,但这种角色对教师的工作生活质量没有显著影响。     

合作指数与社会距离对合作行为的影响

利用囚徒困境范式,考察了合作指数CI（0.1~0.9）与社会距离（亲密、陌生）对个体合作行为的影响。结果发现,社会距离和合作指数均会对合作行为产生影响,两者的交互效应不显著;合作率会受到合作指数的促进作用,但不会随合作指数的增高立即增长;在CI = 0.1~0.9这9个水平下,亲密被试间的合作率均显著高于陌生被试间的合作率。这一结果说明,合作指数对合作行为的促进作用存在阈值;社会距离缩小可促进个体的合作倾向增强,并更快地达到合作水平;合作指数与社会距离相互独立地影响合作行为。     

Odor as a conditioned inhibitor: Applicability of the Rescorla-Wagner model to feeding behavior

Hooded rats were given conditioned inhibition training in which the taste of saccharin alone was always followed by induced illness, but the taste of saccharin plus the odor of amyl acetate was not. In a series of three subsequent tests—summation, enhancement of conditioning, and retardation—it was demonstrated that the odor had acquired active inhibitory properties. The results paralleled those obtained with more traditionally studied stimuli and techniques and hence were found to be readily predictable from a recent model of conditioning set forth by Rescorla and Wagner (1972).     

Reconstruction of arbitrary versus logical sequences by preschool children

The ability of preschool children to construct and reconstruct ordered sequences was examined in a series of four experiments. In Expt. 1, the task was to copy, with the model present or absent, the order of items pegged on a clothesline. In Expts. 2–4, the subjects were required to reconstruct ordered series of pictures from memory. In all experiments, the orders were either logical or arbitrary. Reconstruction of an arbitrary series of events is within the problem solving capacity of 4-yr-old children if (a) reconstruction takes place in the presence of the model or follows immediately upon the removal of the model and (b) the original sequence is presented simultaneously. If, however, the lag between viewing and reconstruction is increased and/or the original set is not viewed simultaneously, as a unit, performance declines. The provision of an inherent order to the items within a set, either by introducing a connective narrative, or a depicted logical sequence, is sufficient to maintain that order over time and to provide a unifying cohesion to the items when viewed successively.
