The decline of aggressiveness in male mice during group caging as determined by punishment delivered by the cage mates

Group-housed rodents are generally less aggressive than isolated counterparts. The present study examined the role of defeat by cage mates as a reason for this decline in aggressiveness. In Experiment I, highly aggressive isolated male mice were introduced into aggressive or nonaggressive resident groups. The intruder's level of aggressiveness directed toward a group-housed standard opponent declined more rapidly after daily exposure to the aggressive than to the nonaggressive groups. Intruders in the aggressive groups received more attacks from their cage mates, and delivered fewer attacks to them than did the intruders in the nonaggressive groups. In Experiment II, the intruders lived for seven days in small wire net cages in the middle of the group cages. Their level of aggressiveness toward standard opponents decreased little during the preexposure but after being put freely into the groups, their aggressiveness declined to a minimal level within a day. Experiment III showed that when the wire net protection in the middle of the cage was installed after the group caging experience, the aggressiveness of the intruders did not return to the isolation level as effectively as it did in isolation. This is explained by the aggression-inhibiting content that the cues from the cage mates have acquired during group caging. The decline of aggressiveness in male mice during group caging is determined by punishment delivered by the cage mates.

SIDE EFFECTS OF THERAPEUTIC PUNISHMENT ON ACADEMIC PERFORMANCE AND EYE CONTACT

The effects of therapeutic punishment delivered following inappropriate behavior on the academic responding and eye-to-face contact of 2 persons with developmental handicaps was examined using a counterbalanced alternating treatment design. Each subject was sequentially taught by two therapists each day. While one of the therapists taught the subject, the second therapist stood in close proximity directly behind the subject. During baseline, neither therapist delivered punishment following inappropriate behavior. During the treatment condition, one of the therapists delivered all punishment regardless of whether she was teaching or standing behind the subject. The therapist who delivered all punishment for 1 subject did not deliver any punishment for the other subject. During the last condition, the therapist delivering all punishment was reversed for 1 of the subjects. The results indicated that the task being taught was mastered by each subject only when the therapist delivering punishment was teaching. Data collected also indicated that each subject made more eye-to-face contact when the therapist delivering all punishment was teaching. Although neither therapist had to deliver punishers often, punishment had to be administered less often when the therapist teaching the subject was also the therapist delivering punishment.     

Punishment of an alternative behavior generates resurgence of a previously extinguished target behavior

Resurgence is often defined as the recurrence of an extinguished behavior when a more recently reinforced alternative behavior is also extinguished. Resurgence has also been observed when the alternative behavior is devalued by other means (e.g., reinforcement rate or magnitude reductions). The present study investigated whether punishment of an alternative behavior would generate resurgence. A target response was reinforced during Phase 1 and then extinguished in Phase 2 while an alternative response was reinforced. During Phase 3, response‐dependent foot shocks were superimposed on the schedule of reinforcement for the alternative response and shock intensity was escalated gradually across sessions. Resurgence of the target response was reliably observed, mostly at higher intensities. The effect was replicated in two subsequent exposures to the sequence of conditions, with resurgence tending to occur at the lowest foot shock intensity. These results suggest that devaluation of an alternative behavior via punishment can generate resurgence. Although it is difficult to reconcile the overall pattern of results with Bouton's context account, these findings are consistent with the suggestion that resurgence results from a “worsening of conditions” for the alternative behavior and with the formalization of that suggestion in terms of a choice‐based matching‐law account (i.e., Resurgence as Choice).     

Child Outcomes of Nonabusive and Customary Physical Punishment by Parents: An Updated Literature Review

This article updates the only previous systematic literature review of child outcomes of nonabusive and customary physical punishment by parents. The outcomes differ by methodologic, child, and subcultural factors as well as by how the physical punishment was used. All six studies that used clinical samples (including four randomized clinical studies) and all three sequential-analysis studies found beneficial outcomes, such as reduced noncompliance and fighting, primarily when nonabusive spanking was used to back up milder disciplinary tactics in 2- to 6-year olds. Five of eight longitudinal studies that controlled for initial child misbehavior found predominantly detrimental outcomes of spanking. However, those detrimental outcomes were primarily due to overly frequent use of physical punishment. Furthermore, apparently detrimental outcomes have been found for every alternative disciplinary tactic when investigated with similar analyses. Such detrimental associations of frequent use of any disciplinary tactic may be due to residual confounding from initial child misbehavior. Specific findings suggest discriminations between effective and counterproductive physical punishment with young children. More research is needed to clarify the role of spanking and alternative disciplinary tactics in control system aspects of parental discipline.     

论西方主流正义概念发展中的嬗变与综合（下）

在西方思想中,正义概念自产生以来历经了许多演变。从希腊神话、梭伦、柏拉图、亚里士多德一系的主流希腊思想,接通中世纪基督教的良心观念,经注入自然法的启蒙观念,汇合为自由主义的体系,并在此母体上吸收社会主义思想的部分影响,这构成了西方正义概念迄今发展的主脉。许多思想与观念都对正义的概念发生深刻影响。它的种种涵义是从它产生以来在整个西方历史中逐步增添、发展、补充进去的。在这些历史的嬗变中也不断产生新的综合形式。大致地说,在它产生于希腊思想之后,在基督教教义、自然法理论、近现代自由主义与社会主义的观念基础上都产生着新的综合。罗尔斯公平的正义的理论是西方概念在当代的一个最重要的综合。     

“金钱-环境”复合收益的风险决策:价值取向的影响

现实中的环境决策,往往要在多个由"金钱-环境"复合而成的结果间做选择。人们如何对异质复合结果进行评估与选择,是决策研究面临的新课题。本研究着重考察个体金钱取向和环境取向的相对强度对复合收益风险决策的影响。结果表明,无论是采用自陈量表(实验1)或内隐联想测验(实验2)来测量价值取向,还是采用混词造句任务(实验3)来启动价值取向,均发现价值取向相对强度对复合风险决策有显著影响。(1)相比于金钱取向占优的个体,环境取向占优的个体在进行复合风险决策时更偏好环境风险较小的复合选项;(2)在复合选项等价匹配任务中,环境取向占优的个体会赋予复合选项中的环境收益以更高权重,倾向于用更多的金钱收益来弥补环境收益的风险折扣;(3)在复合收益风险概率匹配任务中,环境取向占优的个体更倾向于为获取倍增的环境收益而承担更大的复合收益风险。作为对复合结果风险决策的首次探索,本研究初步回答了不同价值取向的个体在金钱-环境复合风险决策中更倾向于规避什么风险、拿什么冒险以及为什么冒险等问题,为今后进一步开展复合决策研究打下了理论和方法基础。     

Race for Power in Public Good Games with Unequal,Unstable Punishment Power

Decentralized punishment can maintain contributions to a public good at a high level. This positive effect holds even for situations involving inequality in punishment power, meaning that the relative costs for punishment differ between persons. We extend this line of research by examining the additional influence of instability of and thus potential competition for punishment power in public good experiments. As in previous research, inequality is operationalized by assigning the role of a ‘strong player’ to one group member, who can punish others at a reduced cost compared to other players. Instability is operationalized by the fact that the role assignment can change across rounds and is contingent on behavior in previous rounds. Three experiments show that under unequal, unstable (punishment‐) power, individuals behave more competitively and engage in a race for power resulting in detrimental effects for the group. Specifically, we find that (i) unstable power goes along with a disproportionate use of punishment; (ii) not inequality by itself but rather the combination of instability and inequality causes this effect; and (iii) this excessive use of punishment is found not only when the role of the strong player is assigned to individuals who previously behaved rather selfishly but also when prosocial behavior leads to the top, speaking for a generalizability of our findings. Implications for organizational settings are discussed. Copyright © 2016 John Wiley & Sons, Ltd.     

Self-punishment promotes reconciliation with third parties by addressing the symbolic implications of wrongdoing

Self-punishment is a highly costly—and potentially harmful—way transgressors can respond to a wrongdoing. In this research, we propose that people might punish themselves in part because it has a communicative social function. Three studies using hypothetical vignettes showed that self-punishment facilitates reconciliation with third party observers by addressing the symbolic implications of wrongdoing. Specifically, self-punishment establishes a moral value consensus and/or diminishes offender status/power, and through this, increases third party perceptions of justice and transgressor remorse, and the third party's willingness to reconcile. This effect was robust to manipulations designed to make third parties question the sincerity of the self-punisher's intention. Self-punishment thus serves a beneficial interpersonal function by repairing social bonds between transgressors and their peers.     

Stimulus control and generalization of point-loss punishment with humans

Two experiments demonstrated stimulus control and generalization of conditioned punishment with humans. In both studies, responses first were reinforced with points exchangeable for money on a variable-interval schedule in the presence of one line length (S(D)). Next, a second line length was introduced, and point loss followed every response in the presence of that line (S(D)p). In the final training condition, points were deducted at session end. Response rate was lower in the presence of the S(D)p despite equal rates of points for money in the presence of both stimuli. In generalization testing for Experiment 1, the two lines were included in a 10-line continuum; S(D)p fell in the middle and the trained SD was at one end. Lines were presented randomly, and point delivery and loss contingencies were as in training but with points available in the presence of all lines. For all subjects, response rates were lowest around S(D)p and increased towards the SD end of the continuum. Because testing included only one or two lines beyond S(D), this pattern did not rule out S(D) generalization. Thus, in Experiment 2, stimuli beyond S(D) were added to generalization tests. Response rates did not decrease as a function of distance from S(D), clarifying the demonstration of punishment generalization.
