This paper addresses some of the dynamics, resistances, and transference and countertransference considerations in group psychotherapy with eating disordered patients. Several resistances are delineated, including guilt over being helped, the recreation of early problems around control and forced feeding, and withdrawal as a defensive operation. A brief vignette is presented which highlights the demand on the part of the therapist as well as the patient to contain and manage feelings rather than acting on them. Lastly, the author argues that group participation helps the patient to identify, articulate, and accept feelings and to promote assertiveness.This paper is based on a presentation given at the Training Institute for Mental Health on May 11, 1991. 相似文献

Honeybees (Apis mellifera) were classically conditioned with odor as conditioned stimulus (CS), sucrose as unconditioned stimulus (US), and proboscis extension as response. The purpose of Experiment 1 (Ns = 26 and 27) was to look for facilitation of forward conditioning by CS-US overlap, but rapid conditioning without overlap left little room for improvement. In 2 further experiments, CS and US were simultaneous, and response to odor alone was measured in subsequent tests. In Experiment 2, a Simultaneous group (N = 25) responded more to the training odor than did an Unpaired control group (N = 25). In Experiment 3, a differentially conditioned Simultaneous group (N = 29) responded more to an odor paired with sucrose in training (S+) than to an odor presented alone (S-). The implications of the results for the problem of the role of amount of reward in honeybee learning are considered. 相似文献

Postinstitutional arrests and state hospitalizations of 191 patients placed on conditional release (CONREP group) were compared to those of 44 patients released from the same California state hospital with no aftercare due to expiration of commitment terms (MAXOUT group). The two groups were not randomly determined but were comparable in demographic characteristics and rates of preprogram arrest. The CONREP group had a significantly lower community-period arrest rate than did the MAXOUT group (p <.001). Survival rate analyses, using time until arrest and time until revocation as dependent variables, suggested that revocations during the first 240 days of community re-entry reduced the potential arrest rate within the CONREP group. Results were discussed in terms of the “criminalization hypothesis” as well as the crime-preventive possibilities of the conditional release mechanism. 相似文献

Human analog tests of object permanence were administered to various breeds of adult dogs (Canis familiaris). Experiment 1 showed that the performance of terriers, sporting, and working dogs did not differ. Dogs succeeded in solving invisible displacement problems, but performance was lower than in visible displacement tests. Familiarity with the task had some influence because invisible displacement tests were more successful if they were preceded by visible displacement tests. In Experiment 2, odor cues from the target object and the hiding screens were available or were masked. Results confirmed that success was lower in invisible than in visible displacement tests and that these problems were solved on the basis of representation of visual information rather than on the basis of olfactory cues or of local rule learning. Dogs are compared with other species that display Stage 6 object permanence. 相似文献

This study attempted to apply the relative deprivation theory to preferential selection research. Two questions were addressed
in this context: First, does preferential selection cause feelings of injustice or deprivation? and, second, can the magnitude
of such feelings of injustice be predicted? A questionnaire was designed to assess fairness perceptions of all types of selection
outcomes: preferential selection; together with selection involving discrimination against minorities and selections without
either forms of discrimination. Results showed that preferential selection caused feelings of injustice. The level of felt
injustice associated with preferential selection was identical to that due to discrimination against minorities. Further,
the magnitude of felt injustice due to preferential selection could be predicted by the size of the discrepancy in “performance-relevant
merits” between the selected minority candidate and the unsuccessful majority candidate. The study also compared effects of
the “self-other” comparison process, used in previous relative deprivation research, and a “other-other” comparison process
on justice perception. Implications of the results for the application of relative deprivation theory to preferential selection
research were discussed. 相似文献

Measures of spatial cognition, neighborhood knowledge, and neighborhood use from the research described by Walsh, Krauss, and Regnier (1981) were examined to determine if laboratory tests of spatial cognition were significant predictors of older adults' use of their neighborhoods. The overall results show that laboratory-based measures of spatial cognition and subjects' knowledge of their neighborhoods are both significant predictors of their use of neighborhood goods and services. The ability to learn and remember the location and orientation of objects, when contextual cues were not provided at test, was more predictive of the participants' neighborhood use than either the participants' number of years in the neighborhood or their mobility. Spatial memory as measured by the Educational Testing Service Building Memory task predicted neighborhood knowledge, which was predictive of neighborhood use. 相似文献

Elders exposed to either progressive or imaginal relaxation procedures reported significant relaxation effects and showed improvement on measures of personal functioning. The results of the Physical Assessment Scale of the Relaxation Inventory indicated that relaxation responses were acquired within and across sessions. Large, consistent changes in relaxation occurred in all 4 sessions. The Symptom Checklist-90-R, which measures self-reported personal adjustment, showed significant positive changes following relaxation training and at 1-month follow-up. Elders who imagined muscle tension release profited as much as those engaged in actual muscle tension-release activities. This finding is of importance for older adults who may experience physical limitations that contraindicate muscle-tension-release procedures. 相似文献

Confirmatory factor analysis of Wallston's Multidimensional Health Locus of Control Scale and Krantz's Health Opinion Survey was conducted using 197 nondiabetic and 171 diabetic older adults. Qualified support was found for the 3-factor structure of the Wallston measure when applied to older adults. The Krantz model provided a less-than-adequate representation of the older sample's data. When the items from these 2 measures were combined, a 4-factor structure was found. Multisample simultaneous factor analyses using LISREL revealed that the factor structures of the Wallston and the Krantz measures fit the diabetic and the nondiabetic samples fairly equivalently. Despite the similarities in factor structures, diabetic individuals reported greater belief in powerful others and less desire for behavioral involvement in the health-care process than did nondiabetics. 相似文献
