利他动机对中小学教师知识共享的影响——组织认同和组织支持感的调节作用

为探讨利他动机、组织认同和组织支持感对知识共享的影响,选取北京市不同学区的20所中小学校的教师进行问卷调查,使用利他行为问卷、组织认同问卷、组织支持感问卷和知识共享问卷获得有效数据1342份。结果发现：（1）中小学教师的利他动机对其知识共享具有显著的正向预测作用;（2）组织认同在中小学教师利他动机与知识共享之间起到调节作用;（3）组织支持感对中小学教师利他动机与组织认同对知识共享的交互效应具有高阶调节作用。本研究检验了个体因素（利他动机）与组织因素（组织认同、组织支持感）变量对知识共享的共同作用,对提升中小学教师知识共享具有一定的指导作用。

Rethinking Epistemic Relativism

“Relativism” is often treated as a dirty word in philosophy, but relativistic theories are not entirely unappealing—they have features that might be tempting if they weren't thought to be outweighed by problematic consequences. The aim of this paper is to rethink both our attitude to epistemic relativism and the basic features of the view itself. The paper discusses four objections and uses them to isolate five constraints on a more plausible epistemic relativism. It then sketches out a view that meets all of these constraints. This stratified epistemic relativism offers a complex, socially informed picture of justification that accounts for the many different kinds of roles that epistemic agents act, and think, in accordance with each day, and can serve as a starting point for constructing a more detailed epistemic relativism, which could secure its appealing benefits without incurring the costs traditionally associated with relativist views.     

The effects of a public address system on the off-task behavior of elementary physical education students

The purpose of this study was to determine the effects of teacher feedback delivered via a public address system on the off-task behavior of elementary-school physical education students. A multiple baseline design across three classes was used in this investigation. Results indicated a consistent decline in off-task behavior when the public address feedback system was used.     

Rewarded remembering: dissociations between self-rated motivation and memory performance

People often claim that they perform better in memory performance tasks when they are more motivated. However, past research has shown minimal effects of motivation on memory performance when factors contributing to item-specific biases during encoding and retrieval are taken into account. The purpose of the present study was to examine the generality of this apparent dissociation by using more sensitive measures of experienced motivation and memory performance. Extrinsic motivation was manipulated through competition instructions, and subjective ratings of intrinsic and extrinsic motivation were obtained before and after study instructions. Participants studied a series of words, and memory performance was assessed by content recall (Experiment 1) and source recall (Experiment 2). Both experiments showed dissociation between subjective ratings of extrinsic motivation and actual memory performance, so that competition increased self-rated extrinsic motivation but had no effects on memory performance, including source recall. Inconsistent with most people's expectations, the findings suggest that extrinsic motivation has minimal effects on memory performance.     

Affektive Interaktion zwischen Patienten und Therapeuten

Zusammenfassung Eine positive therapeutische Beziehung wird therapieschulenübergreifend als wichtige Voraussetzung für den Therapieerfolg angesehen. Meist wird jedoch in Studien lediglich die schriftliche Patienteneinschätzung erfasst. Nonverbale Aspekte der Interaktion zwischen Patienten und Therapeuten werden kaum untersucht. Aus einer Studie zur Vorhersage des Erfolgs stationärer Fokaltherapie werden affektive Interaktionsprozesse im Erstinterview exemplarisch zwischen einer erfolgreichen und einer nicht erfolgreichen Behandlung mit mikroanalytischen Verfahren (facial action coding system, FACS) verglichen. In der nicht erfolgreichen Therapie waren die mimischen Affektäußerungen reziprok; Therapeutin und Patientin zeigten ähnliche vorherrschende (sog. Leit-)Affekte. Erfolgreicher waren die Behandlungen, wenn die Therapeuten komplementäre Affektmuster zeigten. Implikationen für Behandlungstechnik, Supervision und Weiterbildung werden diskutiert.     

Academic Self-Schemas and their Self-Congruent Learning Patterns: Findings Verified with Culturally Different Samples

This paper reported two studies investigating high school students’ academic self-schemas in learning mathematics and their self-congruent learning engagement patterns. Using cluster analyses, Study 1 located two contrasting groups of students holding positive and negative self-schemas in learning mathematics among Chinese participants. MANOVA analyses showed that these two groups of Chinese schematic students differed from each other in the use of achievement goals, approaches to learning, and expected levels of performance. These findings were validated and extended in Study 2 using a culturally different sample, Australian students. Again, cluster analyses successfully classified Australian participants into positive and negative schematic clusters. It was also found that these two groups of schematic students approached learning mathematics in a self-congruent manner similar to those found in Study 1. The converging results in both studies lent empirical support to the theoretical formulation of positive and negative schematic students and the validity of using the self-schema concept to investigate motivation and learning. The differences in their learning engagement patterns were discussed in terms of students’ different academic self-schemas in learning mathematics.     

Changes in the structure of children's isometric force variability with practice

This study examined the effect of age and practice on the structure of children's force variability to test the information processing hypothesis that a reduction of sensorimotor system noise accounts in large part for age-related reductions in perceptual-motor performance variability. In the study, 6-year-olds, 10-year-olds, and young adults practiced on 5 consecutive days (15 trials/day), maintaining for 15-s trials a constant level of force (5 or 25% of maximum voluntary contraction) against an object using a pinch grip (thumb and index finger). With increasing age, the amount of force error and variability decreased, but the sequential structure of variability increased in irregularity. With practice, children reduced the amount of variability by changing the structure of the force output so as to be more similar to that of their older counterparts. The findings provide further evidence that practice-driven changes in the structure of force output, rather than a decline in the amount of white noise, largely account for age-related reductions in the amount of force variability.     

Motivating operations and terms to describe them: some further refinements

Over the past decade, behavior analysts have increasingly used the term establishing operation (EO) to refer to environmental events that influence the behavioral effects of operant consequences. Nonetheless, some elements of current terminology regarding EOs may interfere with applied behavior analysts' efforts to predict, control, describe, and understand behavior. The present paper (a) describes how the current conceptualization of the EO is in need of revision, (b) suggests alternative terms, including the generic term motivating operation (MO), and (c) provides examples of MOs and their behavioral effects using articles from the applied behavior analysis literature.     

THE EFFECT OF TOKEN REWARDS ON “INTRINSIC” MOTIVATION FOR DOING MATH

This study used a multielement baseline design to analyze the effects of token rewards delivered contingent upon completion of math problems by 2 middle-school boys. Time spent on math and number of work pages completed increased (with high accuracy) during reward conditions and were maintained during fading and withdrawal. At follow-up, time spent and work pages completed remained well above baseline for 1 boy and fell below for the other, while accuracy remained high and ratings of liking math were the highest possible for both boys. Overall, the results are inconsistent with warnings about use of token rewards to motivate children.
