In two human skin conductance conditioning experiments we investigated whether processing of stimulus compounds can be influenced by past experience. Participants were either pre-trained with a discrimination problem that could be solved elementally (A+, B−, AB+, C− in Experiment 1 and A+, AB+, C−, CB− in Experiment 2) or one that required a configural solution (AB+, BC−, CD+, DA− in Experiment 1 and A−, AB+, C+, CB− in Experiment 2). After pre-training, participants were shown an EX+, FX− discrimination. Subsequently, responding to individual components (E and F) was tested. After elemental pre-training, participants showed larger responses to the component from the previously reinforced compound (E) than to the component from the nonreinforced compound (F) whereas no such difference was found after configural pre-training. This means that the kind of pre-training influenced whether the later discrimination problem was processed elementally or configurally. The results indicate that organisms can flexibly process stimulus compounds in different ways. 相似文献

The primary purpose of the study was to test a hypothetical model for aggressive and delinquent conduct problems in adolescence. A total of 168 adolescents from 121 families were studied using several questionnaires and a semi‐structured interview. The following factors were considered: obstetric complications, temperament (novelty‐seeking), self‐esteem, family influences (perceived parenting, alcohol abuse/dependence of parents, antisocial personality disorder of the father) and peer‐group characteristics (peer rejection and membership in a deviant peer group). The evaluation methods applied included correlation analyses and testing of two hypothetical models using structural equation modeling. The correlation analyses revealed significant relationships between adolescent aggressive and delinquent behavioral problems and parental antisocial behavior; perceived parental rejection and low emotional warmth; adolescent novelty‐seeking, self‐esteem, peer rejection and peer deviance. The two empirical models, separately for aggressive and delinquent behavior problems, revealed direct relationships between paternal antisocial behavior, parental rejection, adolescent novelty seeking, peer deviance, peer rejection, and offspring aggression and delinquency. There were, however, two differences with respect to the relationships between peer rejection, peer deviance, aggression and delinquency. First, peer rejection was more strongly associated with aggressive behavior and only moderately linked to delinquency. Second, deviance in the peer‐group was found to be closely related with delinquency but only moderately with aggression. Our findings suggest that several pathways for aggressive and delinquent conduct problems are comparable while others were not. Regarding the findings of the empirical models, we conclude that only intervention measures that include parents, peers and individual adolescents may help decrease the incidence of aggressive and delinquent conduct problems.

Addiction develops on the basis of a psychic disorder but acquires relative autonomy. Therefore, psychodynamic therapy of addiction needs its own theoretical foundation and specific diagnostic instruments. The process of the subjective acceptance of the addiction by the addict himself is introduced as an important concept. The continuum of acceptance is differentiated into three levels: defense, acceptance, and compensation. It is argued that a specific diagnosis of acceptance connected with the system of Operationalized Psychodynamic Diagnostics (OPD) can contribute to a more differentiated therapy of addiction. A rating scale for the measurement of the acceptance of addiction is proposed. It defines the three levels mentioned above, divides each into two sub-levels and lists specific items. Questions of application are discussed. Clinical experience indicates that the application of the scale together with the OPD instruments improves the planning of addiction therapy. 相似文献

ALTSim is a MATLAB-based simulator of several associative learning models, including Pearce’s configural model, the extended
configural model, the Rescorla-Wagner model, the unique cue hypothesis, the modified unique cue hypothesis, the replaced elements
model, and Harris’s elemental model. It allows for specifying all relevant parameters, as well as exact stimulus sequences
by graphical user interfaces. It is an easy-to-use tool that facilitates evaluating and comparing the featured associative
learning models. ALTSim is available free of charge from www.staff.uni-marburg.de/~lachnit/ALTSim/. 相似文献

Stalking victims show a high level of psychological disturbance and frequently need professional help. Thus, stalking must be considered as a serious issue in the field of psychosocial care. However, specific intervention programs to support stalking victims are not available. This paper reports on a pilot project that offers therapeutic help to stalking victims via a structured outpatient group therapy approach. The program aims at setting up appropriate behavior patterns concerning contact with the stalker, strengthening the victims’ self-efficacy and developing coping strategies for stalking-related stress situations. To investigate the effectiveness of the group program, an evaluation study has been conducted using self-report inventories, interview data and biological parameters. Preliminary results from 4 completed groups with 13 participants, indicating that the approach is highly effective, are reported. The potential of the group approach to improve psychosocial care provision for stalking victims is discussed. The need to integrate psychotherapeutic approaches into a multi-professional support system for stalking victims, comprising legal counsel, police measures and psychosocial interventions, is emphasized. 相似文献

ABSTRACT— Stress affects memory, yet no study has investigated the effects of stress on memory inhibition: Remembering not only facilitates later recall, but also inhibits retrieval of related material, a phenomenon known as retrieval-induced forgetting. We investigated the effects of stress on this mechanism, which is thought to adaptively guide memory selection. Participants learned categorized lists and were then exposed to either a psychosocial laboratory stressor or a cognitively challenging control treatment. They then actively retrieved parts of the previously learned material. Finally, memory for all initially learned items was tested. In the stress group, unlike in the control group, intervening retrieval practice did not impair final recall. Moreover, salivary cortisol levels increased and psychological well-being decreased in the stress group only. Thus, psychosocial stress abolishes retrieval-induced forgetting. This effect may result from stress-induced hormone release from the hypothalamic-pituitary-adrenal (HPA) axis and may have implications for educational, legal, and clinical issues. 相似文献

Cultural perceptions by immigrant service providers and employers potentially shape the employment trajectories of immigrants. I examine perceptions of what motivates immigrants to participate in the Canadian labour market through a Vancouver-based interview survey with immigrant service providers, employment counsellors, NGO administrators and employers who service and/or employ newcomers from South Asia and the former Yugoslavia. The results reveal that multiple perceptions coexist. These perceptions project that immigrants work as a means of survival, a moral obligation, a quest for social distruction and an instrument of social integration. Our understanding of ethnic segmentation of immigrant labour should consider these perceptions. 相似文献

In order to investigate whether the Lidcombe Program effects a short-term reduction of stuttered speech beyond natural recovery, 46 German preschool children were randomly assigned to a wait-contrast group or to an experimental group which received the Lidcombe Program for 16 weeks. The children were between 3;0 and 5;11 years old, their and both of their parents’ native language was German, stuttering onset had been at least 6 months before, and their stuttering frequency was higher than 3% stuttered syllables. Spontaneous speech samples were recorded at home and in the clinic prior to treatment and after 4 months. Compared to the wait-contrast group, the treatment group showed a significantly higher decrease in stuttered syllables in home-measurements (6.9%SS vs. 1.6%SS) and clinic-measurements (6.8%SS vs. 3.6%SS), and the same increase in articulation rate. The program is considered an enrichment of currently applied early stuttering interventions in Germany.
Educational objectives: Readers will discuss and evaluate: (1) the short-term effects of the Lidcombe Program in comparison to natural recovery on stuttering; (2) the impact of the Lidcombe Program on early stuttering in German-speaking preschool children. 相似文献

Temperament profiles from infancy to middle childhood: development and associations with behavior problems 总被引:1,自引:0,他引:1
The authors applied I-States as Objects Analysis (ISOA), a recently proposed person-oriented analytic approach, to the study of temperament development in 921 Norwegian children from a population-based sample. A 5-profile classification based on cluster analysis of standardized mother reports of activity, sociability, emotionality, and shyness at ages 18 months, 30 months, 4-5 years, and 8-9 years was interpretable and highly replicable. The prevalence of temperament profiles changed markedly with age, and individual stability in temperament profiles was significant. Specific typical and atypical developmental sequences of profiles were identified. Selective patterns of concurrent group differences in externalizing and internalizing problems by temperament profiles were remarkably similar across ages. The findings to some degree support the notion that individual temperament-variable values take on meaning in relation to the whole individual configuration and indicate some lawfulness in temperament changes over time. Future person-oriented studies of temperament development should replicate the current results using multiple data sources, rigorous tests of gender differences, and latent group modeling.
