Warmup in avoidance as a function of time since prior training

On avoidance procedures, rats and pigeons typically show warmup effects, characterized by improving performance within sessions and loss of the improvement (“warmup decrement”) between sessions. Between-session losses were examined by varying the time between periods of avoidance training. In one experiment, rats lived fulltime in conditioning chambers while intermission intervals were varied. In a second experiment, the animals lived in home cages between sessions; timeout intervals were introduced at midession, producing recurrence of warmup in the second half-session. In both experiments, the warmup decrements increased substantially as the timeout or intersession intervals were increased from zero to 30 minutes. With intervals of 60 or 120 minutes, the decrements approached or exceeded those obtained with intervals of a day or more. When avoidance was interposed between appetitive sessions, the appetitive responding was disrupted, but this seemed unrelated to the warmup or to the proficiency of avoidance. The warmup in avoidance shares characteristics with transient punishment effects, with the Kamin effect, and with habituation phenomena, but it is premature to assume that they reflect common processes.     

ACCEPTABILITY OF ALTERNATIVE TREATMENTS FOR DEVIANT CHILD BEHAVIOR

The acceptability of alternative treatments for deviant child behavior was evaluated in two experiments. In each experiment, clinical cases were described to undergraduate students along with four different treatments in a Replicated Latin Square Design. The treatments included reinforcement of incompatible behavior, time out from reinforcement, drug therapy, and electric shock and the treatments were described as they were applied to children with problem behaviors. Experiment 1 developed an assessment device to evaluate treatment acceptability and examined whether treatments were rated as differentially acceptable. Experiment 2 replicated the first experiment and examined whether the severity of the presenting clinical problem influenced ratings of acceptability. The results indicated that treatments were sharply distinguished in overall acceptability. Reinforcement of incompatible behavior was more acceptable than other treatments which followed, in order, time out from reinforcement, drug therapy, and electric shock. Case severity influenced acceptability of alternative treatments with all treatments being rated as more acceptable with more severe cases. However, the strength of case severity was relatively small in relation to the different treatment conditions themselves which accounted for large portions of variance.     

Selective punishment of interresponse times

Lever pressing by two squirrel monkeys was maintained under a variable-interval 60-second schedule of food presentation. When response-dependent electric shock was made contingent on comparatively long interresponse times, response rate increased, and further increases were obtained when the minimum interresponse-time requirement was decreased. When an equal proportion of responses produced shock without regard to interresponse time, rates decreased. Thus, shock contingent on long interresponse times selectively decreased the relative frequency of those interresponse times, and increased the relative frequency of shorter interresponse times, whereas shock delivered independent of interresponse times decreased the relative frequency of shorter interresponse times while increasing the frequency of longer ones. The results provide preliminary evidence that interresponse times may be differentiated by punishment, further supporting the notion that interresponse times may be considered functional units of behavior.     

Choice, changeover, and travel: A quantitative model

Six pigeons were trained on concurrent variable-interval schedules in which responding on fixed-interval schedules was required to give access to the alternate schedule. Responding on the concurrent schedules was not allowed, after changing over had commenced, until the changeover schedule had been completed. In Parts 1 to 3 of the experiment, the changeover fixed-interval schedules were equal and were 0 s, 10 s, and 20 s, respectively. In each part, the relative frequency of reinforcement obtained on the concurrent schedules was varied over at least five conditions. In Part 4, the concurrent schedules were equal, and one changeover fixed-interval schedule was twice the other. Under these conditions, the absolute sizes of the changeover schedules were varied. Increasing the changeover requirement from 0 s to 10 s (Parts 1 and 2) resulted in increases in the sensitivity of behavior allocation to reinforcers obtained, but no further increase was obtained when the changeover schedules were increased to 20 s (Part 3). In Part 4, performance was biased towards the concurrent schedule that took less time to enter. These results are consistent with a subtractive punishment model of travel in which the degree of punishment is measured by the number of reinforcers apparently lost from a schedule when the subject changes to that schedule. Absolute times spent on the main keys could be accurately described by a previous model of changeover performance.     

Changes in a multiple-response repertoire during response-contingent punishment and response restriction: Sequential relationships

A multiple-response baseline of four activities was established using gerbils as subjects. When one of the baseline responses was punished (Experiment 1) or restricted (Experiments 2 and 3), only the most probable of the alternative baseline responses increased. The response most likely to follow the punished or restricted responses during baseline sessions was also suppressed during subsequent punishment or response-restriction treatment.     

Punitive emotions and norm violations

The recent literature on social norms has stressed the centrality of emotions in explaining punishment and norm enforcement. This article discusses four negative emotions (righteous anger, indignation, contempt, and disgust) and examines their relationship to punitive behavior. I argue that righteous anger and indignation are both punitive emotions strictly speaking, but induce punishments of different intensity and have distinct elicitors. Contempt and disgust, for their part, cannot be straightforwardly considered punitive emotions, although they often blend with a colder form of indignation to favor low-cost, indirect, and collective forms of punishment such as mockery, exclusion, and ostracism.     

Blame,desert and compatibilist capacity: a diachronic account of moderateness in regards to reasons-responsiveness

This paper argues that John Fischer and Mark Ravizza's compatibilist theory of moral responsibility cannot justify reactive attitudes like blame and desert-based practices like retributive punishment. The problem with their account, I argue, is that their analysis of moderateness in regards to reasons-responsiveness has the wrong normative features. However, I propose an alternative account of what it means for a mechanism to be moderately reasons-responsive which addresses this deficiency. In a nut shell, while Fischer and Ravizza test for moderate reasons-responsiveness by checking how a mechanism behaves in a given time slice across other possible worlds, on my account we should ask how that mechanism behaves in this world over a span of time – specifically, whether it responds to reasons sufficiently often. My diachronic account is intended as a drop-in replacement for Fischer and Ravizza's synchronic account.     

中俄处罚人体器官移植犯罪法规比较与思考

人体器官移植为20世纪生物工程领域中具有划时代意义的技术。我国是世界上第二大人体器官移植国,然而近年来非法器官移植现象日益增多,我国现行法规对人体器官移植犯罪惩处力度不够。器官移植应依法进行,为了给我国人体器官移植犯罪科学立法提供借鉴,通过比较分析,发现俄罗斯器官移植犯罪直接入刑法,我国器官移植犯罪为间接入刑,规定不完善,配套法律缺失,附加民事责任不具体,没有对被害人的赔偿条款。建议我国刑法设置非法器官移植犯罪,并附加具体的民事责任。     

Punishment under threat: The role of personality in costly punishment

It is often assumed that people engage in costly punishment of third parties for prosocial reasons. In this study, we examined to what extent people engage in costly punishment of third parties in response to a perceived punishment threat rather than due to prosocial reasons. Using a modified public goods game with a punishment stage, we show that personality plays an important role in determining which of these processes drive costly punishment. We found that Honesty-Humility, which is related to prosociality, facilitates costly punishment independent of expected punishment to oneself, while Emotionality, which is related to fearfulness, facilitates punishment that is mediated by expected punishment. Agreeableness, which is related to anger and displaced aggression, had no effect on costly punishment.     

Racialized Religion and Judicial Injustice: How Whiteness and Biblicist Christianity Intersect to Promote a Preference for (Unjust) Punishment

America's judicial system is both exceptionally punitive and demonstrably unjust toward racial minorities. While these dual realities are structured into America's institutions, we propose they are also partially sustained by the intersection of ideologies that are both racialized and sacralized. Using multiple waves of the General Social Surveys and a unique measure that asks Americans to choose between two forms of judicial injustice (wrongful conviction or erroneous acquittal), we examine how white racial identity intersects with biblical literalism to bolster America's bent toward unjust punitiveness. In the main effects, Americans who affirm biblical literalism are more likely to show a preference for convicting the innocent, as are whites compared to Black Americans. Examining interaction effects, however, we find whiteness moderates the influence of biblical literalism such that only white biblical literalists (as opposed to non‐white biblical literalists or white non‐biblical literalists) are more likely to prefer wrongful conviction. Indeed, in our full model, being a white biblical literalist is the strongest predictor of preferring wrongful conviction. We theorize that preference for wrongful conviction over erroneous acquittal stems, at least in part, from the combination of sacralized authoritarianism and perceived racial threat.
