Exposure plus response prevention has been demonstrated to be effective in the treatment of bulimia nervosa. However, when done individually, it is labor intensive and cost-ineffective. In the present study exposure plus response prevention was used in the context of a 6-wk., 12-session behavioral group. In addition to the exposure plus response-prevention component, other techniques included self-monitoring, cognitive restructuring, eating-habit stabilization and problem-solving. Eight bulimic women, vomiting a minimum of five times per week for at least a year, participated in the group. At the end of treatment significant reductions in bingeing and vomiting behaviors were reported by all but one subject, substantiated by significantly lower depression scores (Beck Depression Inventory) and binge-eating scores (Binge Eating Scale). At 6 mo. and 1 yr. posttreatment, 6 of 8 subjects reported averaging less than one binge-purge episode per week, one subject continued unchanged, and one subject had relapsed. A group of wait-list control subjects reported essentially no change in binge-purge frequency over the treatment period. Exposure plus response prevention conducted in a behavioral group context appears to be a cost-effective alternative to individual treatment. 相似文献

Traditional studies of deterrence have focused on punishment with less regard for the rewards of both crime and noncrime. Influenced by work in economics and behavioral psychology, more recent studies have departed from tradition by incorporating rewards for crime. To this extent, they should be regarded as advances over the more traditional approaches. Notwithstanding these advances, variations in both the probability and magnitude of reward for noncrime have not been systematically included in these more recent theories of choice. In an attempt to determine whether opportunities for noncrime are either central or trivial to the criminal decision-making process, the present study fitted two alternative models to experimental data involving risk-taking: (a) the economic utility model employed by Piliavin, Gartner, Thornton, and Matsueda (1986) in their study of criminal choice; and (b) the satisfaction balance model developed by Gray and Tallman (1984). Results showed that while both models explained significant amounts of variation in the dependent variable, the Gray-Tallman model provided a substantially better fit of the data. Despite limitations inherent in experimental studies as, for example, limitations surrounding the issue of external validity, the findings strongly suggest that opportunities for noncrime are as important as rewards and costs for crime in the process by which criminal decisions are made. 相似文献

The belief-in-equality construct is defined as the belief that general ability and potential are widely distributed throughout the human population, rather than being limited to an elite minority. Data from a 21-item belief-in-equality inventory and from two construct-validation tasks were gathered using a liberal-arts undergraduate sample of 201 students. Of the two validation tasks, one indicated strong construct validity ( p < .015), however, the second one produced correctly patterned but insignificant results. The results showed that leaders with a high belief in equality put more funds into training their subordinates and had a tendency to delegate more authority to them than leaders with a weak belief in equality. 相似文献

The purpose of this study was to investigate the relationship between disordered eating, the Superwoman ideal, competitiveness, and achievement motivation. The EAT-26, Personality Research Form (Achievement scale), and Self-Roles Inventory were administered to 69 10–12th-grade girls (69.6% White, 11.6% Hispanic, 5.8% Black, 5.8% Asian, 7.2% no information on ethnicity). EAT-26 scores were not significantly associated with attending an academically competitive high school, having a high achievement motivation, or considering a number of roles as important to one's sense of self (adherence to the Superwoman ideal). EAT-26 scores were significantly higher among the girls attending the average high school. It is important to conduct further investigations of the Superwoman ideal since it has been posited as a risk factor for eating disorders, but has been the focus of only a few empirical studies. 相似文献

Fifteen tension headache subjects were allocated to one of three groups: direct EMG feedback (from a site corresponding to the source of pain), indirect EMG feedback (from a site not corresponding to the source of the pain) and relaxation instructions. There were two base-line, six treatment and one post-treatment sessions. No significant differences were found between base-line and post-treatment EMG levels, for any of the groups; however, some significant reductions in levels were obtained within sessions. EMG levels recorded during headache attacks did not differ significantly from levels recorded during base-line. Frequency and intensity of headaches were significantly reduced, particularly in the relaxation group. At follow-up this improvement was maintained for subjects with forehead pain, but differences between the groups had disappeared. 相似文献

College students in two psychology courses estimated their confidence in passing and their anticipated score for three examinations. On the first examination the results from both courses supported the prediction that women, compared to men, would be less confident of passing, would predict lower scores, and would underestimate their obtained scores. These sex differences disappeared, as predicted, on the second and third examination for the course, in which the situation remained relatively constant over the term. However, contrary to predictions, the sex differences were maintained over all three examinations for the second course, which involved different instructors for each exam. Thus, the effects of feedback on performance expectancies seem to be vulnerable to situational changes. 相似文献

Different groups of rats received different numbers of compound CS (light/noise) conditioning trials in the CER procedure. The amount of suppression evident to the single elements of the compound decreased as a function of the number of previous compound trials. This loss of CR strength was interpreted as a configuring effect. Further experimental comparisons indicated that the configuring effect could not be readily explained in terms of a generalization decrement or a stimulus novelty hypothesis. 相似文献

Five pigeons were given single-stimulus training on an 8-sec differential-reinforcement-of-low-rate schedule followed by steady-state generalization training using 12 wavelength stimuli. Three birds had a high percentage of reinforced responses on the training schedule and flat generalization gradients of total responses. The birds with fewer reinforced responses had much steeper generalization gradients. Generalization gradients plotted as a function of both stimulus wavelength and interresponse time showed that for most birds, stimulus control was restricted to responses with long interresponse times. Responses with very short interresponse times were not under stimulus control and there was some evidence of inhibitory control of short interresponse times. Interresponse-times-per-opportunity functions, plotted as a function of stimulus wavelength, showed that stimulus wavelength controlled the temporal distribution of responses, rather than the overall rate of response. The data indicate that the differential-reinforcement-of-low-rate schedule generates several response categories that are controlled in different ways by wavelength and time-correlated stimuli, and that averaging responses regardless of interresponse-time length obscures this control. 相似文献

School psychologists serving a national, systematic sample of public elementary and secondary schools were surveyed regarding recent referrals. Most referrals were initiated by school staff members (75% of referrals), and the majority occured initially through formal mechanisms (55% of referrals). Most informal requests for assistance or information eventually became, or were thought likely to become, formal referrals. In 92% of cases, the referral agent's initial communication with the psychologist included some designation of what the pupil was doing or not doing that was viewed as problematic. Poor academic performance was of primary concern in 52% of referrals and social/emotional problems in 31%. More boys were referred than girls, and one-half of referrals from the elementary grades involved pupils in grades K-2. Frequency of referral and reason for referral were not independent of pupil's grade or sex. Reason for referral was independent of time of year (October vs. May) and geographical region. 相似文献
