A large body of research demonstrates a strong social component to people's pain experiences and pain‐related behaviours. We investigate this by examining the impact of social‐influence processes on laboratory‐induced pain responses by manipulating the social‐categorical relationship between the person experiencing pain and another who offers reassurance. We show that physiological arousal associated with laboratory‐induced pain is significantly lower in normal, healthy participants following reassurance about the pain‐inducing activity when that reassurance comes from an in‐group member in contrast to reassurance from an out‐group member and a no reassurance control. These data are consistent with predictions derived from self‐categorization theory, providing convincing empirical support of its analysis of social influence using a non‐reactive measure. These data also represent a clear advance within the pain literature by identifying a possible common process to the social‐psychological component of pain responses.

The legal system has been preparing for an explosion of epigenetic issues in public health, environmental regulation and litigation. So far, this explosion has been muted, and for now epigenetic data protection merely seems to be “enjoying” the same technological and legal challenges experienced by other clinical and research data. However, three areas of development suggest where epigenetic data protection may prove problematic. This article examines these three issues, noting the rapid expansion of research based on EMR-sourced clinical data, the large number of data protection models that can apply to genetic data (including point-of-use prohibitions on discrimination and confidentiality), and the increasing and controversial dangers of deidentified information being reidentified.

The benefits of humor are briefly reviewed, and the ways in which humor can be effectively used in the client—counselor relationship are explored (i.e., using humor as a diagnostic tool and as a therapeutic tool). Finally counseling vignettes are provided and admonitions regarding the improper application of humor in counseling are reviewed.  相似文献

In the current study, we examined the utility of a procedure consisting of noncontingent reinforcement with and without response cost in the treatment of inappropriate vocalizations maintained by automatic reinforcement. Results are discussed in terms of examining the variables that contribute to the effectiveness of response cost as treatment for problem behavior maintained by automatic reinforcement.  相似文献

Choice between sucrose and wheel-running reinforcement was assessed in two experiments. In the first experiment, ten male Wistar rats were exposed to concurrent VI 30 s VI 30 s schedules of wheel-running and sucrose reinforcement. Sucrose concentration varied across concentrations of 2.5, 7.5, and 12.5%. As concentration increased, more behavior was allocated to sucrose and more reinforcements were obtained from that alternative. Allocation of behavior to wheel running decreased, but obtained wheel-running reinforcement did not change. Overall, the results suggested that food-deprived rats were sensitive to qualitative changes in food supply (sucrose concentration) while continuing to defend a level of physical activity (wheel running). In the second study, 15 female Long Evans rats were exposed to concurrent variable ratio schedules of sucrose and wheel-running, wheel-running and wheel-running, and sucrose and sucrose reinforcement. For each pair of reinforcers, substitutability was assessed by the effect of income-compensated price changes on consumption of the two reinforcers. Results showed that, as expected, sucrose substituted for sucrose and wheel running substituted for wheel running. Wheel running, however, did not substitute for sucrose; but sucrose partially substituted for wheel running. We address the implications of the interrelationships of sucrose and wheel running for an understanding of activity anorexia.  相似文献

We conducted an analysis of precurrent skills (responses that increase the effectiveness of a subsequent or \"current\" behavior in obtaining a reinforcer) to facilitate the solution of arithmetic word (story) problems. Two students with developmental disabilities were taught four precurrent responses (identifying the initial value, change value, operation, and resulting value) in a sequential manner. Results of a multiple baseline design across behaviors showed that the teaching procedures were effective in increasing correct performance of each of the precurrent behaviors with untaught problems during probes and that once the precurrent behaviors were established, the number of correct problem solutions increased.  相似文献

This study investigated the relationship between recall of real‐life pretrial publicity (PTP) in a high‐profile fraud case and subsequent reasoning about the trial evidence and verdict decisions. Tracking the reasoning and verdict judgments of 50 mock jurors during a video simulation of the trial material, the effect of factual recall of PTP was compared with recall indicating an affective or evaluative response from the PTP. Affective/evaluative recall, but not factual recall, was significantly associated with anti‐defendant reasoning and confidence in guilt. This effect was partially mediated by reasoning developed during the course of evidence presentation. The potentially prejudicial effect of affective/evaluative recall of PTP is discussed in terms of it activating an explanatory structure that frames evidence interpretation.  相似文献

Six male albino rats were placed in running wheels and exposed to a fixed-interval 30-s schedule of lever pressing that produced either a drop of sucrose solution or the opportunity to run for a fixed duration as reinforcers. Each reinforcer type was signaled by a different stimulus. In Experiment 1, the duration of running was held constant at 15 s while the concentration of sucrose solution was varied across values of 0, 2.5. 5, 10, and 15%. As concentration decreased, postreinforcement pause duration increased and local rates decreased in the presence of the stimulus signaling sucrose. Consequently, the difference between responding in the presence of stimuli signaling wheel-running and sucrose reinforcers diminished, and at 2.5%, response functions for the two reinforcers were similar. In Experiment 2, the concentration of sucrose solution was held constant at 15% while the duration of the opportunity to run was first varied across values of 15, 45, and 90 s then subsequently across values of 5, 10, and 15 s. As run duration increased, postreinforcement pause duration in the presence of the wheel-running stimulus increased and local rates increased then decreased. In summary, inhibitory aftereffects of previous reinforcers occurred when both sucrose concentration and run duration varied; changes in responding were attributable to changes in the excitatory value of the stimuli signaling the two reinforcers.  相似文献

The interplay between two perspectives that have recently been applied in the attitude area—the social identity approach to attitude‐behaviour relations (Terry & Hogg, 1996 ) and the MODE model (Fazio, 1990a )—was examined in the present research. Two experimental studies were conducted to examine the role of group norms, group identification, attitude accessibility, and mode of behavioural decision‐making in the attitude‐behaviour relationship. In Study 1 (N = 211), the effects of norms and identification on attitude‐behaviour consistency as a function of attitude accessibility and mood were investigated. Study 2 (N = 354) replicated and extended the first experiment by using time pressure to manipulate mode of behavioural decision‐making. As expected, the effects of norm congruency varied as a function of identification and mode of behavioural decision‐making. Under conditions assumed to promote deliberative processing (neutral mood/low time pressure), high identifiers behaved in a manner consistent with the norm. No effects emerged under positive mood and high time pressure conditions. In Study 2, there was evidence that exposure to an attitude‐incongruent norm resulted in attitude change only under low accessibility conditions. The results of these studies highlight the powerful role of group norms in directing individual behaviour and suggest limited support for the MODE model in this context.
