Base-rate neglect as a function of base rates in probabilistic contingency learning

When humans predict criterion events based on probabilistic predictors, they often lend excessive weight to the predictor and insufficient weight to the base rate of the criterion event. In an operant analysis, using a matching-to-sample paradigm, Goodie and Fantino (1996) showed that humans exhibit base-rate neglect when predictors are associated with criterion events through physical similarity. In partial replications of their studies, we demonstrated similar effects when the predictors resembled the criterion events in terms of similarly skewed base rates. Participants' predictions were biased toward the more (or less) frequent criterion event following the more (or less) frequent predictor. This finding adds to the growing evidence for pseudocontingencies (Fiedler & Freytag, 2004), a framework that stresses base-rate influences on contingency learning.     

Individual differences, intelligence, and behavior analysis

Despite its avowed goal of understanding individual behavior, the field of behavior analysis has largely ignored the determinants of consistent differences in level of performance among individuals. The present article discusses major findings in the study of individual differences in intelligence from the conceptual framework of a functional analysis of behavior. In addition to general intelligence, we discuss three other major aspects of behavior in which individuals differ: speed of processing, working memory, and the learning of three-term contingencies. Despite recent progress in our understanding of the relations among these aspects of behavior, numerous issues remain unresolved. Researchers need to determine which learning tasks predict individual differences in intelligence and which do not, and then identify the specific characteristics of these tasks that make such prediction possible.     

The Meaning of “Existence” and the Contingency of Sense

In this paper I argue first for a revisionary ontology, that is, for an understanding of “existence” as the property of a field not to be empty. In this context, I distinguish between “metaphysics” (the theory of totality or of fundamental reality) and “ontology” (the systematic investigation into the meaning of “existence”). In the second part, I provide a sketch for a corresponding revisionary theory of the modalities in light of the new ontology proposed.     

Effects of the good behavior game across classroom contexts

The Good Behavior Game (GBG), a well‐researched classroom group contingency, is typically played for brief periods of time, which raises questions about the effects on subsequent contexts. This study used a multiple baseline design and showed that when the GBG was implemented in one context, behavior improved in only that context. Behavior improved in the subsequent activity only when the GBG was implemented.     

Programming a randomized dependent group contingency and common stimuli to promote durable behavior change

Low levels of academic engagement may impede students’ acquisition of skills. Intervening on student behavior using group contingencies may be a feasible way to increase academic engagement during group instruction. The current study examined the effect of a randomized dependent group contingency on levels of academic engagement for second‐grade participants receiving small‐group reading and writing instruction. The results showed that a randomized dependent group contingency increased the academic engagement of primary participants and several of the other participants during small‐group instruction. The findings also showed that high levels of academic engagement were maintained when common stimuli were present and the dependent group contingency was withdrawn.     

Step it up! Using the good behavior game to increase physical activity with elementary school students at recess

We evaluated the effects of a modified version of the Good Behavior Game (GBG) on the number of steps taken by students during school recess. We divided a class into two teams, and awarded the team with the highest step counts at the end of each game raffle tickets for a school‐wide lottery. The GBG was compared to recess periods without the game using an alternating‐treatments design. Students took more steps while playing the GBG than they did during recess periods without the game.     

ETERNITY,TIME, AND SPACE

Abstract. The concepts of space and time are important in physics and geometry, but their definition is not the exclusive prerogative of those sciences. Space and time are important for ordinary human experience, as well as for philosophy and theology. Samuel Clarke, Gottfried Wilhelm Leibniz, Isaac Newton, Immanuel Kant, and Albert Einstein are important figures in shaping our understandings of space, time, and eternity. The author subjects their arguments to critical examination. Space is neither an infinite and empty receptacle (Newton) nor a system of relations in the mind (Leibniz). Infinite space and time can be interpreted as expressing God's eternity and omnipresence in relating to the creation (Clarke), but such an interpretation is enhanced by Kant's thinking, to clarify that even though time and space are differentiated in individual events, the whole is at the same time present. Even human experience recognizes this wholeness, and for God eternity is the simultaneous presence and possession of the wholeness. The temporal existence of finite entities is also related to a future participation in God's eternal life. Concepts of contingency are brought into the discussion as well.

群体多样性研究迄今为止已经取得了丰硕的研究成果, 但是群体多样性对群体过程和群体效能的影响机制仍然存在大量不甚明了的地方。本文首先回顾群体多样性近期的研究进展, 在此基础上着重阐述基于群体断层理论的多样性研究的一系列理论成果和实证结论, 强调对最佳设计的理解和引入情境因素的考察。本文最后将讨论多样性研究和群体断层理论未来的发展趋势, 并就多样性研究成果对管理实践的启示做出分析。     

情绪词对新异刺激喜好度变化的调节机制

通过三个实验探讨了情绪词的情绪信息对新异刺激喜好度变化的调节机制。实验采用评价条件化(Evaluative Conditioning)范式, 将新异刺激(相当于条件刺激, CS)与情绪词(相当于无条件刺激, US)配对呈现, 最后测量被试对新异刺激的喜好程度。三个实验通过设置表面故事, 控制新异刺激与情绪词间的配对关系, 并改变任务的加工深度, 揭示了情绪词调节新异刺激喜好度变化的机制。研究结果表明, 情绪词对新异刺激喜好度的调节不依赖于对刺激间偶联关系的意识以及被试的任务状态, 是一种自下而上的自动化的联想学习过程。     

Contingency, Education, and the Need for Reassurance

This short paper is a response to Richard Smith’s ‘Abstraction and finitude: education, chance and democracy’. In his paper Smith contends that a rationalist agenda dominates education and democracy today, and that this agenda by rendering us insensitive to the tragic dimension of life, breeds a sense of hubris, or arrogance towards fate which is fuelled by an inordinate confidence in our knowledge. In the worlds of education and politics it has led to an obsession with management and transparency, and to students who fear to take risks. As a specific example of this, he takes up the recent fixation in universities with learning how to learn, which he says leads to an over-emphasis on skills in the curriculum, and to an ‘audit’ culture. While sympathising with much of his analysis of the latter, my counter-suggestion is that the contemporary world lacks anything but a sense of the contingency of things, to the contrary, that at the heart of its mangerialist culture and its performatist ethos lies the need for reassurance. My response focuses on the politics of the self-directed learner that lies at the heart of the lifelong learning literature, on learning how to learn, on the notion of transparency and on the transparent society, and on the politics of contingency and scepticism.
