The present research was concerned with identifying and validating the problematic interpersonal situations of male veteran drug addicts. In Study I, 20 addicts self-monitored the situations with which they had difficulty coping and their associated characteristics throughout a 2-week period. Fifty situations were obtained and then rewritten into specific interpersonal scenarios. In Study II, a second group of 36 addicts and a comparison group of 20 disabled veterans rated the commonality and difficulty of each scenario along seven-point scales. Univariate ANOVAs found that five scenarios received ratings greater than four on both scales and were associated with significantly higher ratings by the addicts. These preliminary scenarios may serve as role-play situations during social-skills assessment and training and may provide further information regarding the interpersonal determinants of relapse occasioned in the natural environment. The need for controlled comparison studies using behavioral measures and an overall improvement in the methodological rigor of research in the area is discussed.The authors acknowledge the editorial comments of Ted D. Nirenberg, Ph.D., on an earlier draft of this paper. Portions of these data were presented at the Fifth World Congress on Behavior Therapy, Washington, DC. 相似文献

孕前成瘾药物暴露不仅危害使用者的身体健康,而且会对子代的生理行为造成影响,近年来研究发现表观遗传机制在其中发挥重要作用。孕前成瘾药物暴露会对子代的成瘾易感性和焦虑样行为造成影响,引起子代的抑郁样行为和认知受损。这些现象可能是成瘾药物通过引起亲代生殖细胞内表观遗传修饰变化所致,其中包括印记基因、神经递质系统、BDNF三个方面的表观遗传修饰变化。此外,未来除了加强以上三个方面基因的研究,也需要增加其他方面基因的研究,以及寻找能预测子代异常行为的表观遗传生物标志物。 相似文献

A positive reinforcement contingency increased opioid abstinence during outpatient dose tapering (4, 2, then 0 mg/day during Weeks 1 through 3) in non‐treatment‐seeking heroin‐dependent volunteers who had been maintained on buprenorphine (8 mg/day) during an inpatient research protocol. The control group (n = 12) received $4.00 for completing assessments at each thrice‐weekly visit during dose tapering; 10 of 12 lapsed to heroin use 1 day after discharge. The abstinence reinforcement group (n = 10) received $30.00 for each consecutive opioid‐free urine sample; this significantly delayed heroin lapse (median, 15 days). 相似文献

全球化进程的加快和贸易战的发生让人们处于一种本体不安全的状态中,即人们的本体安全感受到了威胁。本文研究了消费者本体安全感威胁对家乡品牌偏好的影响。三项研究的结果表明,相比本体安全感没有受到威胁的个体,本体安全感受到威胁的个体对家乡品牌的偏好度更高,其中家乡依恋起到了中介作用。具体而言,本体安全感受到威胁的个体更倾向于依恋可以提供常规生活和构建个人身份的家乡,以此寻求本体安全感恢复,从而增加了对家乡品牌的偏好。实验结果还发现,自然栖息地情境展露在本体安全感威胁对家乡品牌偏好的作用中起到调节作用。具体而言,当展露于自然栖息地情境时,本体安全感受到威胁的个体能够通过对自然栖息地这一更广泛的地点依恋来对抗本体安全感威胁,不再需要寻求家乡依恋来缓解本体安全感威胁,从而使其在对家乡品牌和非家乡品牌的偏好上不再呈现出差异。本研究的发现丰富了现有本体安全感和品牌偏好的相关研究,为品牌提供了一种新的本土营销策略,具有丰富的理论贡献和管理启示。 相似文献

Navigation in the Morris swim task as a baseline for drug discrimination: a demonstration with morphine 下载免费PDF全文
Ziegler D Keith JR Pitts RC Galizio M 《Journal of the experimental analysis of behavior》2002,78(2):215-223
A morphine versus saline discrimination was demonstrated using the Morris swim task as the behavioral baseline. The apparatus was a large circular pool filled with water made opaque by floating polypropylene pellets. Rats were placed in the tank in randomly selected locations (12 trials per session) and could escape by swimming to a platform submerged 2 cm below the surface. Morphine (5.6 mg/kg) or saline was injected prior to training sessions. The position of the platform in a given session depended on the drug condition, thus forming the basis for discriminative responding. Three of the 4 rats acquired the discrimination, as evidenced by direct swims to the condition-appropriate platform. Generalization probe sessions were conducted following acquisition. Probe sessions were preceded by injections of morphine (0, 1.0, 3.0, 5.6, or 10.0 mg/kg) and involved placing the rat in the pool for 1 min without a platform. Swim patterns revealed a gradient, with probe swimming more concentrated in the area of the morphine platform position after higher morphine doses. In addition, dose-dependent increases in the likelihood of swimming first to the morphine-associated platform location were obtained. These results illustrate the generality of drug discrimination across different behavioral procedures, and of particular interest with respect to spatial learning, demonstrate interoceptive stimulus control of navigation. 相似文献

The purpose of the present study was to examine whether coping mechanisms predict physical health, after controlling for posttraumatic stress disorder (PTSD) symptom clusters in a non-clinical sample of adults. Data were collected from 483 adults through an online survey. Most of the participants (66.7%) reported lifetime exposure to at least one traumatic event. The final sample of this study included 319 trauma-exposed individuals. Results indicated that PTSD symptoms on the avoidance and hyperarousal clusters had significant positive relationships with self-reported physical health symptoms. After controlling for gender and PTSD, denial, behavioral disengagement, and self-blame significantly and positively predicted physical health symptoms. 相似文献

The effects of income (money available to spend during the experimental session) on human choice were examined in a concurrent-schedule arrangement. Subjects were 7 nicotine-dependent smokers, and reinforcers were puffs on the subject's usual brand of cigarette ("own") and puffs on a less preferred brand of cigarette with equal nicotine content ("other"). Across sessions, income varied and the price of the two reinforcers was held constant, with the other puffs one fifth the price of the own puffs. As income increased, consumption of own puffs increased while consumption of the less expensive other puffs decreased. These effects of income on choice were highly consistent across subjects. For some subjects, however, income had little effect on total puff consumption. Finally, an additional condition examined whether price and income manipulations would have functionally equivalent effects on choice by repeating an income condition in which the price of the other brand was increased. Although the increased price of the other puffs decreased their consumption in 4 subjects, 2 subjects showed increased consumption of the other puffs at the higher price. The results, when defined in economic terms, indicate that the own puffs were a normal good (consumption and income are directly related), the other puffs were an inferior good (consumption and income are inversely related), and the direct relationship between consumption of the other puffs and their price is defined as a Giffengood effect. The latter result also suggests that for these 2 subjects, price and income manipulations had equivalent effects on choice. These results extend findings from previous studies that have examined the effects of income on choice responding to human subjects and drug reinforcers, and provide a framework for further experimental tests of the effects of income on human choice behavior. Methodological and theoretical implications for the study of choice and for behavioral pharmacology are discussed. 相似文献

The purpose of the first experiment was to investigate whether diazepam could acquire anxiogenic properties by signalling an aversive event. Rats were trained in an operant chamber in the pentylenetetrazol (PTZ) model of anxiety. Thereafter the animals were divided into groups that received classical diazepam conditioning (Group 1), and conditioning of diazepam + tone (Group 2). In the test phase diazepam was injected prior to placement in the operant chamber. Group 2 selected the PTZ-appropriate lever more often than the other groups, indicating that the tone induced anxiety, and diazepam did not. Tones and shock may therefore be more easily associated than diazepam and shock. The second experiment investigated this. Rats were trained the same way as in the first experiment. Thereafter the experimental group received injections of a small dose of diazepam prior to a second injection of a large dose of diazepam. The hypothesis was that a compensatory anxiogenic conditional response to diazepam's anxiolytic effect should be elicited by the small dose. There were no differences between the groups in lever selection, indicating that a compensatory anxiogenic response was not elicited. 相似文献

Exposure therapy has demonstrated its efficacy in the treatment of pathological health anxiety—however, psychotherapy research reveals that many patients do not show a clinically significant change. Therefore, improvements are necessary to optimize psychotherapy for pathological health anxiety. Most treatment rationales refer to habituation during exposure as the central mechanism of change. However, there is evidence that extinction learning is mediated by inhibitory learning processes. Targeting these processes may help to improve treatment outcomes in pathological health anxiety. The aim of this review was to adapt, from the inhibitory learning approach and empirical findings, the most promising strategies for the exposure-based treatment of pathological health anxiety. The exposure-optimizing strategies adapted are expectancy violation, combination, variability in contexts and stimuli, affect labeling, and removal of safety signals. A case example illustrates how to implement these methods for patients with pathological health anxiety. 相似文献
