In two experiments, fear was conditioned to the situational cues in one compartment of a hurdle-jumping apparatus and was then extinguished. Subsequently, either one shock (Experiment 1) or three or nine shocks (Experiment 2) were given in a situation distinctively different from that in which conditioning and extinction had taken place. Although some associative strength between the situational cues and fear was shown to have remained after extinction, in neither experiment did the postextinction-shock treatment increase the fear elicited by these cues: Escape-from-fear performance was no better in the shocked groups than in control groups given no additional shock. Thus, the nonassociative hypothesis which postulates that inflating the value of the representation of the UCS with shock-alone presentations can reinstate the extinguished fear of a stimulus was not supported. Rather, the results showed that, after extinction, an increase in fear of a simulus depended on further conditioning to that stimulus. The data also indicated that the nonvisual components of the situational cues predominated over the visual component.  相似文献

To evaluate a contingency interpretation of conditioned inhibition (CI), rats were given “explicity unpaired” training in which the locus and duration of a CS within the inter-US (shock) interval were systematically manipulated for different groups. Summation and retardation tests in Experiment 1 indicated that stronger CI resulted from both a backward and a trace CS than from a midlocus CS of equal or greater duration. Complementing these findings, the same tests in Experiment 2 showed that, by comparison with novel-stimulus controls, CI developed to a trace CS but not to a mid-locus CS, nor to a trace CS that was accompanied by an immediate signal for the US. These findings argue against a contingency interpretation of CI and favor a contiguity interpretation stressing the short-term rehearsal of stimulus events. Such rehearsal of the US allows a backward CS, but not a mid-locus CS with an extended US-CS interval, to be discriminated as a signal for nonreinforcement, and thus to develop as a conditioned inhibitor. Similarly, excitatory conditioning to the memory trace of a CS allows the nominal trace CS to develop as a signal for nonreinforcement, and thus as a conditioned inhibitor, but not when its memory trace is overshadowed by another CS that immediately precedes the US. In short, the development of CI is facilitated when excitation is mediated by the memorial processing of either the US or a discrete CS for the US rather than by contextual cues.  相似文献

This study extends prior research on the intergenerational transmission of relationship instability by examining parents' history of on-off relationships as a predictor of emerging adults' own cycling (i.e., breaking up and renewing with the same romantic partner). Data were collected at a large mid-western university from 702 emerging adults (18–25 years old). Multinomial logistic regression was used to predict the likelihood that participants had cycled in a past or current relationship. Results show that parental cycling increased the likelihood of offspring cycling in a past or current relationship relative to never cycling, and greater uncertainty about the future of the relationship was a mechanism through which such transmission occurred. Findings from this study demonstrate that parental relationship instability can even be consequential for the transient relationships within emerging adulthood, making family history a productive area to explore for practitioners working with cyclical partners and/or emerging adults.  相似文献

This article offers an overview of the 11th Assembly of the World Council of Churches, which met in Karlsruhe, Germany, in August–September 2022. It sets out the context in which the assembly took place, the main issues discussed, and perspectives for the future. The article argues that the assembly in Karlsruhe demonstrated that the ecumenical movement still is alive and can offer enormous potential in a world at the brink of a new East–West divide, facing a significant weakening of multilateral structures of cooperation, and even the threat of nuclear war. Moreover, the Karlsruhe assembly demonstrated that on subjects such as the Middle East, peace ethics, and nationalism, and in the deep commitment and spiritual life of its participants, the ecumenical movement is vital and vibrant and represents a countercultural force against rigid nationalisms.  相似文献

This is the message of the Ecumenical Youth Gathering held in advance of the 11th Assembly of the World Council of Churches, which met in Karlsruhe, Germany, in August–September 2022. In their message, the youth voiced a series of laments, and recognized and prayed for justice, forgiveness, and reconciliation of the wounds the church has inflicted and continues to inflict in the world, and they called on the WCC to provide a meaningful space for an equal representation of young people in all its processes.  相似文献

This paper explores the vertices of Jung's, Anzaldúa's and Benjamin's distinct ontologies and the way in which they connect in the shared recognition that what has been estranged in human history is enigmatically lodged in the world's fabric today. Cultural distress, in other words, is the outcome of what has become repudiated in the self and the collective across time. From this perspective, the paper argues that we have a collective responsibility to listen to the claims of the dead laid bare in moments of contemporary real-world danger and it elaborates the psychical dimensions of being that are cultivated in times of danger. The author contends that these psychical presences are the dead of human history including our ancestral heritage that linger and possibly may penetrate our awareness. They haunt and hold a potential to animate our movement towards a sublimatory process that can be seen as a precursor to social responsiveness and action. The author explores this through her own experience with an example of the spawning of spiritual activism within the socio-political maelstrom of AIDS.  相似文献

The scientific realism debate in philosophy of science raises some intriguing methodological issues. Scientific realism posits a link between a scientific theory's observational and referential success. This opens the possibility of testing the thesis empirically, by searching for evidence of such a link in the record of theories put forward in the history of science. Many realist philosophers working today propose case study methodology as a way of carrying out such a test. This article argues that a qualitative method such as case study methodology is not adequate for this purpose, for two reasons: to test scientific realism is to pose an effects-of-causes question, and observational and referential success are quantities that theories possess to a greater or lesser degree. The article concludes that an empirical test of scientific realism requires a quantitative method.  相似文献

The convergence of dance art and therapeutic culture engendered the development of dance-movement therapy in the mid to late 20th century internationally. This article traces the sociopolitical, institutional, and aesthetic influences that coalesced in this process by contrasting histories of dance-movement therapy in Hungary and in the United States. The professionalization dance-movement therapy, through which it established its own theory, practice, and training institutions, occurred first in the United States in the late 1940s. Modern dancers in the United States began to conceptualize their activity as therapeutic, and the dancer as a (secular) healer, a therapist. The influx of therapeutic concepts into the field of dance is viewed as an example of therapeutic discourse permeating various areas of life in the 20th century. The Hungarian case provides a contrasting history of therapeutic culture, one that deviates from the predominant view of the phenomenon as a product of the global spread of Western modernization and the growth of free-market capitalism. Hungarian movement and dance therapy indeed developed independently from its American predecessor. Its history is intimately tied to the sociopolitical context of state-socialist period, particularly to the institutionalization of psychotherapy in public hospitals, and to the adaptation of Western group psychotherapies within the informal setting of the “second public sphere.” The legacy of Michael Balint and the British object-relations school provided its theoretical framework. Its methodology was rooted in postmodern dance. The methodological differences between American dance-movement therapy and the Hungarian method reflects the shift in dance aesthetics that occurred internationally between 1940 and 1980s.  相似文献
