Abstract Psychophysiological reactivity has been associated with heightened risk of coronary heart disease. Since behavioral processes may contribute to disease etiology, the possibility arises that they might also contribute to disease prevention. The capability of behavioral interventions to modify exaggerated reactivity in Type A men. was therefore, brought under experimental scrutiny. Subjects were 107 male managers. who met the following criteria: (1) no history or current signs of heart disease. (2) presence of Type A behavior pattern, and (3) exaggerated psychophysiological reactivity to mental stress. After matching for age and physical fitness level. participants were randomly assigned to one of three 10-week intervention programs: aerohic training, weight training and cognitive-behavioral stress management. Heart rate and blood pressure were monitored while challenging mental tasks were performed in pre-training and post-training laboratory sessions before and after the intervention programs. Although participants in the two physical activity programs showed the expected physical adaptations, no changes in psychophysiological reactivity were seen in the three groups. This negative result may indicate either that reactivity was not altered owing to the conditions of the present experiment, or that these behavioral interventions are truly without effect. 相似文献

A task force authorized by the Executive Council of the Association for Behavior Analysis International (ABAI) generated the statement below concerning the techniques called restraint and seclusion. Members of the task force independently reviewed the scientific literature concerning restraint and seclusion and agreed unanimously to the content of the statement. The Executive Council accepted the statement, and it was subsequently approved by a two-thirds majority vote of the general membership. It now constitutes official ABAI policy. The position statement is posted on the ABAI Web site (www.abainternational.org/ABA/statements/RestraintSeclusion.asp). The purpose of the position statement is to provide guidance to behavior analysts and other professionals interested in the position of ABAI on these controversial topics. In extreme cases, abuses of procedures erroneously used in the name of behavior analysis are not defensible. On the other hand, behavior analysts acting ethically and in good faith are provided with guidelines for sound and acceptably safe practice. To the extent that behavior-analytic positions influence public policy and law, this statement can be presented to officials and lawmakers to guide informed decision making. At the conclusion of the document, a bibliography is provided of articles and presentations considered by one or more task force members in developing the position statement. 相似文献

In order to fulfill ABET requirements, Northern Arizona University’s Civil and Environmental engineering programs incorporate
professional ethics in several of its engineering courses. This paper discusses an ethics module in a 3rd year engineering
design course that focuses on the design process and technical writing. Engineering students early in their student careers
generally possess good black/white critical thinking skills on technical issues. Engineering design is the first time students
are exposed to “grey” or multiple possible solution technical problems. To identify and solve these problems, the engineering
design process is used. Ethical problems are also “grey” problems and present similar challenges to students. Students need
a practical tool for solving these ethical problems. The step-wise engineering design process was used as a model to demonstrate
a similar process for ethical situations. The ethical decision making process of Martin and Schinzinger was adapted for parallelism
to the design process and presented to students as a step-wise technique for identification of the pertinent ethical issues,
relevant moral theories, possible outcomes and a final decision. Students had greatest difficulty identifying the broader,
global issues presented in an ethical situation, but by the end of the module, were better able to not only identify the broader
issues, but also to more comprehensively assess specific issues, generate solutions and a desired response to the issue. 相似文献

Basic research with pigeons on behavioral momentum suggests that differential reinforcement of alternative behavior (DRA) can increase the resistance of target behavior to change. This finding suggests that clinical applications of DRA may inadvertently increase the persistence of target behavior even as it decreases its frequency. We conducted three coordinated experiments to test whether DRA has persistence-strengthening effects on clinically significant target behavior and then tested the effectiveness of a possible solution to this problem in both a nonhuman and clinical study. Experiment 1 compared resistance to extinction following baseline rates of reinforcement versus higher DRA rates of reinforcement in a clinical study. Resistance to extinction was substantially greater following DRA. Experiment 2 tested a rat model of a possible solution to this problem. Training an alternative response in a context without reinforcement of the target response circumvented the persistence-strengthening effects of DRA. Experiment 3 translated the rat model into a novel clinical application of DRA. Training an alternative response with DRA in a separate context resulted in lower resistance to extinction than employing DRA in the context correlated with reinforcement of target behavior. The value of coordinated bidirectional translational research is discussed. 相似文献

Functional analysis can often be a lengthy process requiring time and resources not readily available to practitioners working with children who exhibit severe problem behavior. The interview‐informed synthesized contingency analysis (IISCA) was recently developed as an alternative functional analysis format that improved analytic efficiency by requiring only 25 min to conduct. Furthermore, a within‐session analysis of the first test session of the entire IISCA could reduce the process to as little as a single 5‐min session. We extended this previous research by conducting what was termed the single‐session IISCA with three boys who exhibited severe problem behavior. A function‐based treatment package, including reinforcement thinning, informed by the results of the single‐session IISCA nearly eliminated problem behavior for all three participants. We suggest that the single‐session IISCA could be a viable alternative to other functional analysis formats when time is limited. 相似文献

This study examined procedures for the assessment and treatment of automatically reinforced vocal stereotypy of a 6‐year‐old girl with autism. Stimulus assessments were conducted to identify toys that were correlated with higher rates of vocal stereotypy and toys that were not. A concurrent operants assessment identified preferred stimuli (toys that produced auditory stimulation), which were then used as reinforcers for the non‐occurrence of vocal stereotypy. A reversal design was used to compare the effects of a fixed time schedule of reinforcement (FT 1‐min) to differential reinforcement for the non‐occurrence of behavior (DRO) to reduce vocal stereotypy. Implementation of the FT schedule revealed no effect, whereas the DRO schedule led to a reduction in the target behavior during treatment sessions and across the school day. This study adds to the body of literature supporting the identification of matched stimuli to reduce non‐socially mediated problem behavior. Copyright © 2005 John Wiley & Sons, Ltd. 相似文献

It has been suggested that the performance of preferred modes of exercise will serve to maximize the affective response to exercise. Support has come from work that has shown the effect of exercise on affect to be mediated by enjoyment. However, there is a need to compare modes of exercise that differ in preference and enjoyment, yet are similar in intensity, duration and muscle group. This experiment was designed to achieve this aim. Thirty-four college-aged women completed 20 minutes of exercise on high and low preference modes of continuous exercise. Intensity was maintained at 65–75% of HRR. Affect was measured by the PANAS, collected prior to and at 5, 20, and 40 min post exercise. Results provided partial support for the hypothesis as mode preference moderated the improvement in positive affect, with no effect on the reduction in negative affect. Interestingly, regardless of mode preference, enjoyment ratings were found to mediate the change in both positive and negative affect. 相似文献
