DOES SENSITIVITY TO MAGNITUDE DEPEND ON THE TEMPORAL DISTRIBUTION OF REINFORCEMENT?

Our research addressed the question of whether sensitivity to relative reinforcer magnitude in concurrent chains depends on the distribution of reinforcer delays when the terminal-link schedules are equal. In Experiment 1, 12 pigeons responded in a two-component procedure. In both components, the initial links were concurrent variable-interval 40-s variable-interval 40-s, and the terminal links were both 20-s interval schedules in which responses were reinforced by either 4-s of grain in one, or 2-s of grain in the other. The only difference between the components was whether the terminal-link schedules were fixed interval or variable intervals. For all subjects, the relative rate of responding in the initial links for the terminal link that produced the 4-s reinforcer was greater when the terminal links were fixed-interval schedules than when they were variable-interval schedules. This result is contrary to the prediction of Grace's (1994) contextual choice model, but is consistent with both Mazur's (2001) hyperbolic value-added model and Killeen's (1985) incentive theory. In Experiment 2, 4 pigeons responded in a concurrent-chains procedure in which 4-s or 2-s reinforcers were provided independently of responding according to equal fixed-time or mixed-time schedules. Preference for the 4-s reinforcer increased as the variability of the intervals comprising the mixed-time schedules was decreased. Generalized-matching sensitivity of initial-link response allocation to relative reinforcer magnitude was proportional to the geometric mean of the terminal-link delays.

Relative Value Units: Using the New “Currency” for Measuring Clinical Productivity in a Productivity/Incentive Plan

This paper presents an overview of a productivity/incentive plan for faculty in an academic medicine center's department of behavioral medicine and psychiatry. The model utilizes the Resource-Based Relative Value Scale (RBRVS) for its measurement of clinical productivity. The paper provides an introduction to RBRVS terminology and how the RBRVS system was developed. The productivity/incentive plan developed for the Department of Behavioral Medicine and Psychiatry, West Virginia University School of Medicine, Morgantown, is described. The advantages and limitations of utilizing Relative Value Units (RVUs) in a productivity model are discussed. The paper may provide helpful insights to those charged with developing productivity/incentive plans at other academic health science centers.     

Two Kinds of Organic Unity

This paper distinguishes two interpretations of G. E. Moore's principle of organic unities, which says that the intrinsic value of a whole need not equal the sum of the intrinsic values its parts would have outside it. A holistic interpretation, which was Moore's own, says that parts retain their values when they enter a whole but that there can be an additional value in the whole as a whole that must be added to them. The conditionality interpretation, which has been defended by Korsgaard, says that parts can change their values when they enter wholes, so no additional value is needed. The paper shows that the two interpretations, which differ on such apparently important issues as the nature of intrinsic value, can always yield the same conclusions about the overall value in a state of affairs, so there is in that sense nothing to choose between them. At the same time, though, the differences between the interpretations make sometimes one and sometimes the other more appropriate for expressing a given evaluative view. In this last connection the paper considers views about beauty, posthumous achievement, vices of disproportion, deserved and compassionate pain, and undeserved and malicious pleasure.     

Mother–child disputes as arenas for fostering negotiation skills

Valsiner's concepts of the zone of free movement (ZFM) and the zone of promoted actions (ZPA) were applied to mother-child disputes to study how mothers discharge their role as experts in negotiation. Twenty mothers of 3-5-year-olds each reported 20 disputes, 10 in which the mother was making a request and 10 in which she was refusing her child's request. The disputes were analysed sequentially using four models, preservation, copycat, reward/punishment, and provision of a rationale. The results showed that perseveration and copycat models were more likely to apply when there was negative affect. Mother's re-requests fitted the reward/punishment model whereas mother's refusals better fitted the provision of a rationale model. Information from follow-up interviews supported the notion that requests and refusals are being socialized differently. The results imply that, whereas children's requests and refusals are within the ZFM, only their requests are within the ZPA.     

Behavioral economics

Economics, like behavioral psychology, is a science of behavior, albeit highly organized human behavior. The value of economic concepts for behavioral psychology rests on (1) their empirical validity when tested in the laboratory with individual subjects and (2) their uniqueness when compared to established behavioral concepts. Several fundamental concepts are introduced and illustrated by reference to experimental data: open and closed economies, elastic and inelastic demand, and substitution versus complementarity. Changes in absolute response rate are analyzed in relation to elasticity and intensity of demand. The economic concepts of substitution and complementarity are related to traditional behavioral studies of choice and to the matching relation. The economic approach has many implications for the future of behavioral research and theory. In general, economic concepts are grounded on a dynamic view of reinforcement. The closed-economy methodology extends the generality of behavioral principles to situations in which response rate and obtained rate of reinforcement are interdependent. Analysis of results in terms of elasticity and intensity of demand promises to provide a more direct method for characterizing the effects of “motivational” variables. Future studies of choice should arrange heterogeneous reinforcers with varying elasticities, use closed economies, and modulate scarcity or income. The economic analysis can be extended to the study of performances that involve subtle discriminations or skilled movements that vary in accuracy or quality as opposed to rate or quantity, and thus permit examination of time/accuracy trade-offs.     

社会价值取向与损失情境对不同时间压力下双人社会困境中合作行为的影响

为揭示双人社会困境中合作行为的影响因素,选取四种不同类型的双人社会困境,采用实验法考察社会价值取向与损失情境对不同时间压力下合作行为的影响。结果显示,亲社会个体的合作率显著高于亲自我个体的合作率,收益情境下的合作率显著高于损失情境下的合作率,在社会困境中双方冲突程度越大合作率越低;此外,高时间压力提升了亲自我个体在囚徒困境以及收益情境下信任困境中的合作率,同时降低了亲自我个体在损失情境下最大差异困境中的合作率。结果表明,社会价值取向、收益损失情境以及困境冲突程度均对合作行为的发生具有影响作用,而时间压力对合作行为的作用也同样受到三者的影响。这些发现能够为合作行为自动性的理论分歧提供新的证据。     

Does forgiving in a collectivistic culture affect only decisions to forgive and not emotions? REACH forgiveness collectivistic in Indonesia

According to some theorising, in collectivistic societies, forgiveness is mainly enacted to maintain relationships, not engender emotional transformation. This present study was designed to explore whether forgiveness affects decisional and emotional forgiveness in Indonesia, a country categorised as collectivistic. The evidence-based REACH Forgiveness psychoeducational group intervention was adapted to collectivistic culture (REACH forgiveness collectivistic; REACH-FC), and its efficacy was assessed in a randomised controlled trial. Undergraduates in Indonesia (N = 97; 24 male; 73 female; ages 16–21) were randomly assigned within a 2 × 3(S) quasi-experimental repeated-measures design comparing immediate treatment (IT) and waiting list (WL) conditions [Condition (IT, WL) × Time ([S] 3 time points). Harmonious value, a personality variable assessing the strength of participants' desire for group harmony, was the covariate. The condition × time (S) interactions for both decisional and emotional forgiveness were significant, challenging some previous literature. Clearly, not all forms of collectivism have similar effects when individuals and communities deal with transgressions.
