Response Form, Force, And Number: Effects On Concurrent-schedule Performance

Six hens responded on concurrent variable-interval (key-peck) variable-interval (door-push) schedules of reinforcement in which the second-order (fixed-ratio) requirements on the alternatives (Experiment 1) or the required door forces (Experiment 2) were varied. The key-peck and door-push response (measured as fixed-ratio completion) and time data were well described by the generalized matching law. However, the manipulations of fixed-ratio requirement and required response force differed in their effects. The manipulations of fixed-ratio size affected the response and time measures differently, producing fairly constant, multiplicative biases only in terms of response allocation. It was argued that variations in fixed-ratio size necessarily change the time allocated to that response unit, and thus changes in time bias were not necessarily a fundamental effect of changing the ratio. In contrast, the changes in response bias were a fundamental result of changes in ratio size. The response-force manipulations produced similar bias shifts in terms of response and time allocation, but they appeared to combine with relative reinforcement rate to affect choice interactively. Specifically, behavior appeared to be biased towards the least effortful (i.e., key-peck) response, but the increases in door force had a larger effect on bias when the hens were making this response infrequently (on a lean schedule). The different effects of the fixed-ratio and response-force manipulations on concurrent performance were partially accounted for by the differing times required to complete each response unit under those manipulations, but this would not account for the interaction. The interaction would be consonant with increased response effort decreasing the effective value of the associated reinforcement schedule.     

What 4′33″ Is

What is John Cage's 4′33″? This paper disambiguates this question into three sub-questions concerning, respectively, the work's ontological nature, the art form to which it belongs, and the genre it is in. We shall see that the work's performances consist of silence (rather than containing environmental sounds), that it is a work of performance art (rather than music), and that it belongs to the genre of conceptual art. Seeing the work in these ways helps us to understand it better, and promises to assuage somewhat the puzzlement and irritation of those who are at first resistant to its charms.     

个体近似数量系统与其数学能力之间的关系：发展研究的证据

Change and Management of Complex Services: The Ethno-narrative Form to Support Good Living and Working Together

Nowadays, managing change in complex services requires that middle management re-designs its objects and professional practices, in order to cope with new needs. It seems therefore crucial to activate training settings that allow managers to: (1) develop research and analytical skills on their own work practices and professional objects; (2) face and manage conflict, related to every change, that represents an opportunity to reflect and review one's own practices; and (3) build new and shared repertories of managerial practices, able to support a better form of living and working together within the management community. Moving from these hypotheses, inside the setting of a training intervention conducted in an educational service, the article discusses a specific tool used to generate opportunity of exchange, and reflection, within a challenging framework of change.     

Eye Movements in Strategic Choice

In risky and other multiattribute choices, the process of choosing is well described by random walk or drift diffusion models in which evidence is accumulated over time to threshold. In strategic choices, level‐k and cognitive hierarchy models have been offered as accounts of the choice process, in which people simulate the choice processes of their opponents or partners. We recorded the eye movements in 2 × 2 symmetric games including dominance‐solvable games like prisoner's dilemma and asymmetric coordination games like stag hunt and hawk–dove. The evidence was most consistent with the accumulation of payoff differences over time: we found longer duration choices with more fixations when payoffs differences were more finely balanced, an emerging bias to gaze more at the payoffs for the action ultimately chosen, and that a simple count of transitions between payoffs—whether or not the comparison is strategically informative—was strongly associated with the final choice. The accumulator models do account for these strategic choice process measures, but the level‐k and cognitive hierarchy models do not. © 2015 The Authors.

支付与报复：成本形式对第三方惩罚的影响

第三方惩罚不仅对惩罚成本的数量敏感,也对成本形式敏感。在保持成本数量相等的情况下,不同形式的惩罚成本会对第三方惩罚的频率产生不同影响。相较支付形式,当惩罚成本采取报复形式时,被试的第三方惩罚频率显著下降。进一步的实验表明,惩罚频率的变化并非因为不同的成本形式所隐含的风险水平有所差异,而是因为被试对不同的成本形式赋予了不同的主观价值。进一步探索更多形式的惩罚成本是未来研究的重要方向。     

中国青少年积极发展量表（简版）的编制：基于一个大样本数据

中国青少年积极发展量表是一个多维度的测评青少年发展过程中积极特性（即品格、能力、自信和联结）的量表,共98个项目。为提高量表的应用推广性,本研究基于一个大样本数据（n=16317, M_年龄=13.13岁, SD=2.52岁）创建了一个该量表的简化版本。通过一系列的验证性因素分析、项目筛选、信效度检验以及交叉验证,简化后量表共48个项目。结果显示,简版量表与原始完整版量表有足够的概念重合度和剖面相似性,且具有可以接受的信效度和测量结构的等值性。     

作文前计划的时间因素对前计划效应的影响

采用自然实验与实验室实验相结合的方法,通过两个实验探讨作文前计划的时间因素对前计划效应的影响。结果发现,作文方式决定前计划用时,前计划用时影响前计划效应,前计划效应决定前计划形式的作用。这一结果表明,在既有前计划又有外部视觉表征的情况下,前计划本身在前计划时限与前计划形式的关系中起着决定性的作用。因为前计划的存在,使外部视觉表征的作用呈现出更为复杂的情况,从而表现为长时限前计划即充分前计划条件下,外部视觉表征具有重要意义,短时限前计划即不充分前计划条件下,计划比外部视觉表征更具价值。
