Stimulus-independent thoughts (SITs) are streams of thoughts and images unrelated to immediate sensory input. Four experiments examined the contribution of aspects of working memory to production of SITs. In Experiments 1 and 2, interventions that were targeted on, respectively, phonological and visuospatial components of working memory both interfered with production of SITs, but there was evidence that these tasks also made demands on central executive resources. Experiments 3 and 4 specifically examined the hypothesis that production of SITs and control of nonproceduralized tasks both depend on central executive resources, and so should show mutual interference. In Experiment 3, prior practice on pursuit rotor and memory tasks reduced the interference with SITs from concurrent task performance. In Experiment 4, randomness within a task involving random-number generation was less when SITs were being produced concurrently than it was when they were not. The results suggest that production of SITs depends on central executive resources.  相似文献

Top-of-the-head worries were elicited from young people, grades 4 to 8, both before and after they completed quantitative risk assessments of specific health and environmental problems. Results revealed that many students carry a substantial worry burden that includes not only personal matters such as grades and social relations, but also concerns about death and about global issues such as homelessness and environmental degradation. The gender and grade differences that emerged were consistent with a developmental extension from self to societal perspectives. Differences in worry profiles from before to after the risk assessment interviews revealed some impact of recent exposure, as illustrated by a pre—post increase from 7% to 30% in students spontaneously expressing AIDS-related concerns. Implications of the breadth and severity of young people's concerns are discussed, as are the ambiguities inherent in standard assessment approaches.This research was supported by grants from the National Institute of Child Health and Human Development (HD27035) and the University of California Universitywide AIDS Research Program (R901040). We very much appreciate the cooperation of Sally Snyder and the Irvine Unified School District, Amy Watson and the Corinne A. Seeds University Elementary School, Trina Panaqua and the Bruin Kids of UCLA, and the Fernald Child Study Center. Special thanks are due to the 4th- through 8th-grade student participants. We are also grateful to Ellen Dellis, Virginia Elderkin-Thompson, Judy Hollingshead, Alison Holman, Judy Koch-Jones, and Kim Witte for their help with the interviews and to Tammy Merlo, Shealen Nash, and Beth Twambley for competent coding assistance. Finally, we thank the anonymous editorial reviewers for constructive comments on the nature of fear and worry.  相似文献

IMPLICIT MEMORY IN AMNESIC PATIENTS:   总被引:1,自引:0,他引:1  
Abstract— Amnesic patients generally exhibit spared priming effects on implicit memory tasks despite poor explicit memory In a previous study, we demonstrated normal auditory priming in amnesic patients on an identification-in-noise test in which the magnitude of priming is independent of whether the speaker's voice is the same or different at study and test In the present experiment, we examined auditory priming on a filter identification test in which the magnitude of priming in control subjects is higher when the speaker's voice is the same at study and test than when it is different Amnesic patients, by contrast, failed to exhibit more priming in a same-voice condition than in a different-voice condition Voice-specific priming may depend on a memory system that is impaired in amnesia  相似文献

This paper discusses issues relating to therapeutic practice based upon the narrative metaphor. A case of someone suffering the effects of Dissociative Identity disorder is used to illustrate the difficulties that clients can experience with the “expert” knowledge conception of therapy. The value of the “respectful” and “non-expert” emphasis of Narrative Practice emerges even when the therapist believes that he or she lacks expertise in the client's apparent “condition.” Three themes emanating from the case form the basis for the discussion: the client's experience of being recruited into accepting the diagnostic label of Dissociative Identity Disorder; the effects of being forced to accept a contract to eliminate self-abusive behaviour; and the therapist's dealing with a gun in the therapy room.  相似文献

This article describes marital therapy with a Holocaust survival couple in which the wife's demands for living bread plays a highly symbolic role in the marital dynamics. The author draws interesting parallels between the experience of the couple and the meaning of the therapy experience for herself.  相似文献

The authors describe and outline how art can be used in existential psychotherapy to help a couple or family uncover, discover, and make use of the meanings and meaning potentials to be found in marital and family life. In existential psychotherapy with couples and families, art can be used to help the members of the relationship notice meaning potentials in the future, honor meaning potentials that have been actualized and deposited in the past, and discover new ways to actualize meaning potentials in the here and now.  相似文献

Among the 200,000 immigrants who entered Israel in 1990 were a considerable number of families headed by single mothers. Their most prominent feature was the fact that a three-generation system—a single Soviet mother, her own mother, and a single child—formed the family unit. Rooted in changes occurring in the Soviet family life cycle over the past 70 years, this configuration is uniquely self-contained. This article is an early inquiry into a new family structure that will become part of the social fabric of the multi-ethnic society in Israel. The challenge will be to help in the absorption process by recognizing, encouraging, and facilitating the strengths this type of family brings with it and to plan support networks to substitute for those left behind.A previous version of this article was presented at the Third World Family Therapy Congress, June 2–6, 1991, Jyvaskyla, Finland.  相似文献

Recent speech research has begun to evaluate the internal structure of categories. In one such study, Kuhl (1991) found that discrimination was poorer for vowel stimuli that were more representative of the category (prototype, or P, set) than it was for less representative stimuli (nonprototype, or NP, set). This finding was interpreted as indicating that a category prototype may function as a “perceptual magnet,” effectively decreasing perceptual distance, and thus discriminability, between stimuli. The present study examines the function of prototypes in a musical category—another natural, but nonspeech category. Paralleling the Kuhl study, representative (P) and less representative (NP) sets of major triad stimuli were constructed, based on equal temperament. Musically experienced subjects rated the stimuli in each set for goodness as a major triad, with the highest rated stimulus serving as a prototype standard for a subsequent discrimination task. Results from the discrimination task demonstrated better performance in the P context than in the NP context. The current nonspeech results indicate that a prototype functions as an anchor rather than a magnet. In addition to providing a natural, nonspeech standard for comparison with speech findings, the results provide some important insights into the nature of musical categories.  相似文献
