Effects of Noncontingent Reinforcement and Choice of Activity on Aggressive Behavior Maintained by Attention

Functional assessments identified that the grabbing behavior of a 24‐year‐old man with intellectual disability was maintained by social positive reinforcement, that is, attention. Aggression was more likely to occur when his social environment changed from high to low attention. An intervention that combined extinction with activity choice and noncontingent reinforcement was most effective at reducing grabbing. The intervention and beneficial effects were maintained over 17 months, although staff retraining was required at 6 and 16 months. Retraining was implemented successfully when aggression increased and procedural integrity had declined. Copyright © 2011 John Wiley & Sons, Ltd.     

正强化和负强化:概念、争议与神经机制

1975年,Michael首次正式提出应放弃"正强化"和"负强化"术语的使用,引起对"正强化和负强化是否本质上具有区别"这一问题的关注和争议。正负强化究竟本质上是否有区分、如何区分、以及区分它们的意义等问题,得到了众多行为心理学家的深入探讨。多数学者再度阐明正强化和负强化具有不同的心理机制,加以区分具有重要应用意义,主张沿用对它们的区分。最近,对正负强化神经机制的研究取得突破性进展,进一步揭示它们具有截然不同的神经相关过程。我们建议,分析强化作用进行时,机体是否在环境条件作用下已经偏离了基础、正常的心理稳态,有助于规范理解强化物启动的是正还是负强化的神经过程。     

Effects of Fixed-Time Reinforcement Delivered by Teachers for Reducing Problem Behavior in Special Education Classrooms

The effects of fixed-time (FT) reinforcement schedules on the disruptive behavior of 4 students in special education classrooms were studied. Attention provided on FT schedules in the context of a multiple-baseline design across participants substantially decreased all students’ challenging behavior. Disruptive behavior was maintained at levels lower than baseline throughout reinforcement thinning and follow-up phases. The results extend existing literature on the use of FT schedules of reinforcement and provide evidence that FT schedules of reinforcement can be practical to implement in special educational classroom settings.     

Signaled Delay of Reinforcement: Effects of Postconditioning Manipulation of Context Associative Strength on Instrumental Performance

Two experiments examined the influence of postconditioning treatments of contextual cues on instrumental responding acquired with a signaled delay of reinforcement schedule. In Experiment 1, mere exposure to the conditioning context after instrumental training resulted in an attenuated response rate during an extinction test. In the second experiment, responding was decreased by exposure to the contextual cues or sessions in which signaled noncontingent reinforcements occurred. The greatest response decrement, however, occurred following unsignaled noncontingent food presentations. The results are discussed with respect to the different roles of contextual cues on operant responding.

Evaluating Treatments for Functionally Equivalent Problem Behavior Maintained by Adult Compliance with Mands During Interactive Play

A primary goal of behavioral interventions is to reduce dangerous or inappropriate behavior and to generalize treatment effects across various settings. However, there is a lack of research evaluating generalization of treatment effects while individuals with functionally equivalent problem behavior interact with each other. For the current study, the severe problem behavior of two participants with developmental disabilities was targeted for assessment and treatment. Results of a functional analysis indicated that for both participants, problem behaviors occurred when destructive behavior produced reinforcement of participant mands . The use of a multiple schedule that alternated between differential reinforcement of other behaviors and differential reinforcement of alternative behavior (mands) was sufficient to produce a significant reduction in problem behavior for one participant; the addition of differential reinforcement of alternative behaviors via compliance was necessary for the second participant. Extended treatment sessions, which focused on interaction between the two participants, involved one therapist concurrently implementing each participant’s treatment while they were directed to play with one another (a situation that previously evoked problem behavior). Results show that each participant’s treatment produced low to zero rates of problem behavior even during extended interactions.

The Effects of Positive and Negative Placebos on Human Memory Performances

Two experiments investigated the possible effects of memory-enhancing and memory-impairing placebo capsules (which participants believed to contain active drugs) on participants' performance in a delayed free recall task. In both experiments participants were randomly assigned to either control, positive, or negative placebo conditions, and their memory performance was tested prior to (baseline trial) and after (test trial) the administration of the placebo. Different patterns of results emerged for positive and negative placebos for actual memory performance measures. Whereas negative placebo produces standard placebo effects by impairing both free recall and accuracy scores on test trial, positive placebo does not affect either of these measures (null placebo effect). On the other hand, both positive and negative placebos produce standard placebo effects with respect to participants' self-reports of perceived changes in memory performance: those in the positive placebo group tend to report that the “drug” improved their performance, and those in the negative group tend to report that it impaired it.     

Effects of Positive and Negative Behavioral Feedback on Subsequent Attitude-Related Action

ABSTRACT This study examined the effect of positive and negative behavioral feedback on subsequent behavior The results indicate that positive and negative feedback concerning how well individuals have acted on their attitudinal in the past have different effects on subsequent behavior These effects are moderated by individual differences in self-monitoring and in the frequency with which an individual has acted on his or her attitude in the past–variables which can be seen as reflecting differences in the extent to which individuals see themselves as persons who act on their attitudes, either in general or in regard to a specific attitudes domain Implications of the findings for understanding the literature on labeling and on feedback about energy use are discussed, as are the practical implications for using behavioral feedback in an effort to increase attitude-related action     

Third Party Power: Some Negative Effects of Positive Incentives

The present study simulated an organizational dispute to examine the effects of reward and coercive third party power on negotiator concessions and negotiator perceptions of the third party. The results indicated that the possibility of third party rewards inhibited negotiator concessions, and the possibility of third party punishments facilitated concessions. This effect was enhanced by negotiator limit. When negotiators had high limits, they made the fewest concessions if the third party could compensate; when negotiators had low limits, they made the greatest concessions if the third party could press. Taken together, the results suggest that negotiators sometimes use concession making as a strategy to affect third party behavior. When negotiators want third parties to provide compensation, as when they have high limits, they reduce their concession making as a way of eliciting the compensation; when they want to avoid third party behavior that is punitive, and they have low limits and room to make concessions, they hasten their concessions to reach agreement quickly and thereby stem the third party's involvement.     

The Effects of Positive Peer Reporting as a Class-Wide Positive Behavior Support

School-wide, selective, and individual positive behavioral supports are critical elements of a comprehensive, tiered model of service delivery. Positive peer reporting (PPR) involves brief, highly structured sessions during which peers are provided the opportunity to praise the behavior of target students. PPR procedures were modified in this study to provide all children in a classroom the opportunity to provide or receive peer praise. The effects of class-wide PPR on teacher-recorded critical events were evaluated using a multiple baseline design across two classrooms. Results indicated marginal improvement across the two settings, as well as supplemental measures of behavior outside of the classroom and class-wide sociometric nominations. Implications for future research and emerging models of school-wide PBS are discussed.     

Preference Assessment for Dimensions of Reinforcement to Inform Token Economies Targeting Problem Behavior

The purpose of the current two-experiment study was to examine the use of a preference assessment for dimensions of reinforcement to inform an effective token economy arrangement. Three participants diagnosed with developmental disabilities who engaged in negatively reinforced problem behavior participated in this study. During Experiment 1, a preference assessment for four dimensions of reinforcement (i.e., quality, immediacy, magnitude, and rate) occurred to inform a more- and less-preferred token economy arrangement. During Experiment 2, a treatment evaluation compared these two token economy arrangements. Results for all three participants showed lower rates of problem behavior under the more-preferred token economy arrangement compared to the less-preferred token economy arrangement. Rates of task completion were higher under the more-preferred token economy arrangement for one of the three participants. Results are discussed in terms of their practical implications for clinicians and educators implementing token economies to manage problem behavior.     

Under Pressure: The Effects of Stress on Positive and Negative Relationship Behaviors

This study investigates the effects of acute stress on positive and negative relationship behaviors, specifically assurances and attention to alternatives. A sample of 129 college students were randomly assigned to either a high or low stress condition, then were led to believe they had the opportunity to interact with attractive potential relationship partners and list compliments about their current partner. Results indicated that those in the high stress condition gave their partner fewer assurances and paid more attention to alternatives. These results suggest that when individuals experience acute stress, they may engage in fewer positive relationship behaviors and more behaviors that are potentially harmful to their relationship.     

The Effects of a Diversity Learning Experience on Positive and Negative Diversity Perceptions

Using a pretest-posttest research paradigm, we administered the Reaction-To-Diversity Inventory to students enrolled in a workplace diversity course at a regional Midwestern university. Our results show that the diversity experience produced an increase in the number of positive and negative perceptions students associated with workplace diversity. Gender also played a significant role in determining diversity perceptions. We discuss the implications of our findings for the design, implementation, and evaluation of diversity learning experiences in academic and corporate settings.     

Positive and Negative Hypothesis Testing by Cooperative Groups

In a rule induction problem positive hypothesis tests select evidence that the tester expects to be an example of the correct rule if the hypothesis is correct, whereas negative hypothesis tests select evidence that the tester expects to be a nonexample if the hypothesis is correct. Previous research indicates the general effectiveness of a positive test strategy for individuals, but there has been very little research with cooperative groups. We extend the analysis of Klayman and Ha (Psychological Review, 1987) of ambiguous verification or conclusive falsification of five possible types of hypotheses by positive and negative tests by emphasizing the importance of further examples following hypothesis tests. In two experiments four-person cooperative groups solved rule induction problems by proposing a hypothesis and selecting evidence to test the hypothesis on each of four arrays on each trial. In different conditions the groups were instructed to use different combinations of positive and negative tests on the four arrays. Positive tests were more likely to lead to further examples than negative tests, and the proportion of correct hypotheses corresponded to the proportion of positive tests, in both experiments. We suggest that positive tests are more effective than negative hypothesis tests in generating further evidence, and thus in inducing the correct rule, in experimental rule induction tasks with a criterion of certainty imposed by the researcher.     

Determ inants of Positive and Negative Generation Effects in Free Recall

Better retention of self-produced as opposed to experimenter-presented material is called generation effect ; the reverse phenomenon is the negative generation effect. Both are found in intentional-learning experiments in which generating versus reading is manipulated between subjects. The present article presents an overview of those findings and aims at clarifying the conditions under which these effects emerge. Experiments 1 and 2 demonstrate that if cuetarget relations are manipulated within one list, a negative generation effect in free recall can be obtained for all items, no matter which cue-target relation they bear. In Experiment 3, cue-target relations were manipulated between lists. Here, a negative generation effect in free recall was found only in lists in which items were cued with words that mismatched the intertarget relations, whereas a positive generation effect was observed in those lists in which the generation cues matched the inter-target relations. A subsequent cued-recall test demonstrated that in cases of mismatch of relations, participants in the generate condition process cue-target relations at the expense of inter-target relations. The three-factor theory can be integrated with the task-demand account in a transfer-appropriate processing framework to accommodate these findings.     

Positive and Negative Effects of Monitoring Popular Films for Historical Inaccuracies

History educators often use popular films in the classroom to teach critical thinking through an exercise that involves identifying historical inaccuracies in the films. We investigated how this exercise affects the acquisition of true and false historical knowledge. In two experiments, subjects studied texts about historical topics and watched clips from corresponding films. Each film contained one piece of information that contradicted the text (i.e. misinformation). Some subjects received instructions to monitor for inaccuracies in the films. After a delay, they were tested on the texts. Monitoring instructions did not reduce subjects' acquisition of misinformation, and even when subjects successfully detected the inaccuracies, they sometimes still reproduced the misinformation. However, when they received feedback about the inaccuracies, the production of misinformation was substantially reduced. Overall, these findings indicate that educators should provide feedback when using popular films for this critical thinking exercise so that students do not acquire false knowledge.

Appetitive and Aversive Reinforcement Schedule Effects on Behavior: A Systematic Replication

Three male volunteers lived for six successive days within a laboratory environment programmed for continuous residence. During days when subjects' work on a multiple task performance battery had the effect of preventing reductions in accumulated group earnings, all subjects complained, one subject stopped working, and another subject's productivity declined. When identical work had the effect of incrementing group earnings, such byproducts of aversive control were absent. These results extend the generality of previous analyses of reinforcement schedule effects on behavior and thereby demonstrate their reliability. The reactions of the subjects to the aversive reinforcement schedule were similar to the reactions of the crew manning the last Skylab mission.

Mood and Organizational Citizenship Behavior: The Effects of Positive Affect on Employee Organizational Citizenship Behavior Intentions

This study, involving 139 employees from a variety of industries, organizations, and positions in Singapore, measured the effects of mood on the intentions of employees to contribute actions that are organizationally desirable but are not part of their formal job requirements (organizational citizenship behavior). After effects of established patterns of historical organizational citizenship behavior, demographic characteristics, and employee positive and negative affectivity had been controlled, stepwise regression analysis revealed that the amount of positive affect currently experienced by an employee significantly influenced the employee's intention to perform specific acts of organizational citizenship.
