GENERATING HYPOTHESES ABOUT THE FUNCTION OF STUDENT PROBLEM BEHAVIOR BY OBSERVING TEACHER BEHAVIOR

We examined whether, as predicted by research on child effects, we could generate hypotheses about the function of student problem behavior by observing the amount of attention teachers provided to students. In the first phase of the study, we observed the amount of attention teachers distributed among small groups of students who exhibited problem behavior in individual or small-group instructional settings (problem behavior presumably maintained by attention or escape). Based on the amount of attention each student received, we generated hypotheses about the function of his or her problem behavior. In the second phase of the study, we determined the accuracy of these predictions by conducting a brief functional assessment with each student. Results confirmed that, for 14 of the 15 students, we were able to generate accurate hypotheses about the function of their problem behavior. These results suggest the potential efficacy of using the amount of attention teachers distribute among groups of students to generate empirically based hypotheses about the function of student problem behavior maintained by attention and/or escape. These results also illustrate the efficiency of this procedure; by observing teacher behavior, we were able to generate hypotheses about the function of problem behavior for several students at one time.     

频率差异假设和长时记忆的视优效应

本文包括长时记忆视优效应的三项实验。实验一使用汉语为学习材料,北京人与广东人为被试;实验二使用英语为学习材料、美国人与中国人为被试;实验三使用日语为学习材料、日本人为被试。三项实验都有视觉、听觉两种呈现方式。三项实验的结果都有利于证明频率差异假设,即如果在书面言语中经验某字词的频率高于在口语中经验该字词的频率,则该字词的视觉呈现优于听觉呈现。     

Positive Interpretation Bias Predicts Longitudinal Decreases in Social Anxiety

Theoretical models of social anxiety suggest that distorted interpretation processes contribute to its development and maintenance, although the pathways through which this occurs are not well understood. Therefore, the present longitudinal study sought to determine whether negative interpretation bias, positive interpretation bias, and interpretation inflexibility (the degree to which participants correctly revise initial interpretations) predict changes in social anxiety over time. In an important advance over prior studies, individual differences in working memory capacity (WMC) were accounted for, as WMC is thought to play a crucial role in the generation and maintenance of interpretation biases. Following a baseline assessment of social anxiety, interpretation biases, and WMC, participants completed follow-up assessments of social anxiety both 2 weeks (n = 106) and 4 weeks (n = 96) later. After controlling for baseline social anxiety and WMC, greater positive interpretation bias was found to predict lower social anxiety at both follow-ups. Neither negative interpretation bias nor interpretation inflexibility was significantly associated with follow-up social anxiety. These results provide support for greater positive interpretation bias as a facilitator of decreases in social anxiety and a potential target for clinical intervention.     

The Multiplicative AHP,SMART and ELECTRE in a Common Context

This paper presents a comparative study of three popular methods for multicriteria decision analysis based on a particular model of human preferential judgement. Since decisions are invariably made within a given context, we model relative preferences as ratios of increments or decrements in an interval on an axis of desirability. Next we sort the ratio magnitudes into a small number of categories, represented by numerical values on a geometric scale. We explain why the analytic hierarchy process (AHP) and the French collection of ELECTRE methods, typically based on pairwise comparison methods, are concerned with categories of ratio magnitudes, whereas the simple multiattribute rating technique (SMART) essentially uses orders of magnitude of these ratios. This phenomenon provides a common basis for the analysis of the methods in question and for a cross-validation of their results. We illustrate the approach via a well-known case study, the choice of a location for a nuclear power plant. We conclude by discussing the scope of the comparative study. © 1997 John Wiley & Sons, Ltd.     

Attachment Relationships as Predictors of Cognitive Interpretation and Response Bias in Late Adolescence

We investigated behavioural and cognitive representations of attachment style. Specifically, we sought to test continuity in attachment style and whether participants' perceptions of their attachments to parents, peers, and romantic partners would predict cognitive interpretation and responses to 12 ambiguous situation scenarios. Participants were 161 undergraduate students (17–20 years) who completed the Parental Bonding Instrument, the Attachment Style Questionnaire and the Inventory of Parent and Peer Attachment (peer subscale). Participants then indicated whether they interpreted ambiguous situations as threatening versus non-threatening and how they would respond (proactively, aggressively, or avoidantly). Regression analyses revealed that insecure parental attachments were the main predictor of participants' interpretations and their planned responses, followed by romantic attachments. Peer attachments played little role in the predictions. These results suggest that interpretation of situations and subsequent plans of action may be influenced by attachment related experiences. We discuss our findings in terms of their relevance to attachment theory and their application to our understanding of the concepts of attachment in development of interpersonal relationships.     

How to Regulate a Practice: The Case of Cosmetic Surgery

How should a practice, subservient to a public good, be regulated in order to guarantee fair access without encouraging improper claims? In the first place, a clear understanding of the goal of the practice is indispensable for knowing what criteria the regulation must contain. As to the purely formal aspect, the regulation of any practice must include both general rules and particular instances. Finally, to resolve conflicts, committees in which different kinds of expertise are represented should be installed. These three theses are illustrated by the Dutch regulation for cosmetic surgery.     

Realism in energy transition processes: an example from Bohmian quantum mechanics

In this paper we study in details a system of two weakly coupled harmonic oscillators from the point of view of Bohm’s interpretation of quantum mechanics. This system may be viewed as a simple model for the interaction between a photon and a photodetector. We obtain exact solutions for the general case. We then compute approximate solutions for the case where one oscillator is initially in its first excited state (a single photon) reaching the other oscillator in its ground state (the photodetector). The approximate solutions represent the state of both oscillators after the interaction, which is not an eigenstate of the individual hamiltonians for each oscillator, and therefore the energies for each oscillator do not exist in the Copenhagen interpretation of Quantum Mechanics. We use the approximate solutions that we obtained to compute Bohmian trajectories and to study the energy transfer between the oscillators. We conclude that, even using the Bohmian view, the energy of each individual oscillator is not well defined, as the nonlocal quantum potential is not negligible even after the coupling is turned off.     

The propensity theory: a decision-theoretic restatement

Probability theory is important because of its relevance for decision making, which also means: its relevance for the single case. The propensity theory of objective probability, which addresses the single case, is subject to two problems: Humphreys’ problem of inverse probabilities and the problem of the reference class. The paper solves both problems by restating the propensity theory using (an objectivist version of) Pearl’s approach to causality and probability, and by applying a decision-theoretic perspective. Contrary to a widely held view, decision making on the basis of given propensities can proceed without a subjective-probability supplement to propensities.     

组织中的社会交换：由直接到间接

社会交换理论被引用来研究组织中的两种交换：员工与所在组织之间的交换——“感受组织支持”（POS）和员工与直接上司之间的交换——“领导—成员交换”（LMX）。以往的研究侧重于“直接交换”,即：从POS和LMX到员工工作产出的直接回归。该文以员工的组织情感承诺和工作满意感为中介变量,考察POS和LMX对员工工作产出的间接影响。在919份有效问卷的基础上,通过结构方程模型的比较,结果发现：组织情感承诺和工作满意感的确可以在POS和LMX与员工工作产出之间承担全部或部分中介的角色。这说明,员工与组织之间、上司与下属之间的交换只有小部分是“直接交换”,大部分则属于“间接交换”。最后,作者讨论了这些新发现的理论意义和实践意义,并指出了该研究的不足之处。
