Many psychoanalysts treat individuals who are simultaneously in couples therapy or whose partners are in individual therapy. If such cases stall, some analysts may seek consultation from a colleague, though most have accepted the tacit historical prohibition against communication between therapists treating members of the same family. Experience, however, suggests that a certain form of communication between such therapists can have a powerfully enhancing effect on the concurrent therapies. After a review of the literature, the advantages, disadvantages, and impediments to collaborative cross-communication are examined. A model is then presented for use in ongoing discussion between therapists, and is illustrated with two clinical examples. The proposed model centers on the transference-countertransference configurations within the therapeutic field, and serves as an organizer highlighting areas for discussion.  相似文献

Electronic journal (e-journal) publishing has started to change the ways we think about publishing. However, many scholars and scientists in the mind and brain sciences are still ignorant of the new possibilities and ongoing debates. This paper will provide a summary of the issues involved, give an update of the current discussion, and supply practical information on issues related to e-journal publishing and self-archiving relevant for the mind and brain sciences. Issues such as differences between traditional and e-journal publishing, open archive initiatives, worldwide conventions, quality control, costs involved in e-journal publishing, and copyright questions will be addressed. Practical hints on how to self-archive, how to submit to the e-journal Psycoloquy, how to create an open research archive, and where to find information relevant to e-publishing will be supplied.  相似文献

A recent study published in Perception & Psychophysics (Donnelly, Found, & Miller, 1999) employs response time (RT) variances (in the form of standard deviations) in addition to mean RTs. Variances can contribute greatly to model testing. However, there is a danger of perpetuating the kinds of logical and methodological errors that have long attended research employing mean RTs alone. This commentary clarifies the theoretical and methodological issues, points out some new results concerning variability in search processes, and indicates how to resolve the global and specific challenges associated with identifying psychological mechanisms.  相似文献

Young children experience difficulties establishing conceptual representations of color compared with everyday objects. We argue that comparing the development of color cognition to that of familiar objects is inappropriate since color is a perceptual attribute that can be abstracted from an object and by itself lacks functional significance. Instead, we compared the recognition, perceptual saliency, and naming of color to that of three other perceptual object attributes (motion, form, and size) in 47 children aged 2 to 5 years as a function of language age. Results revealed that, although color was perceptually salient relative to the other visual attributes, no selective impairment to color cognition (recognition and naming) was found relative to the three other visual attributes tested. Thus, when the appropriate comparisons are made, we find no special delay in the development of color conceptualization. Furthermore, the striking disparity between perceptual saliency and cognition of color in our youngest age groups suggests that perceptual saliency has little influence on the conceptual development of color.  相似文献

One of the relics of positivism has been an underappreciation of the moral and ethical dimensions of psychoanalytic theory and practice. In a positivist metapsychology, cure and therapeutic gain were often defined instrumentally, with relatively little consideration given to aspects of human experience (e.g., moral, cultural, spiritual) that did not fit within a positivist framework. Conceptual and paradigmatic shifts in psychoanalysis have occurred, in part, because of the inability of the classical model to provide a language that adequately captures deeply felt human values and beliefs. Aided by hermeneutic and postmodern influences, many contemporary psychoanalytic theories are beginning to focus greater attention on the notion that analytic therapy is empowered by a set of ethical convictions, beliefs, and commitments, which are tied to a certain understanding of the good life. Along these lines, the author argues that developing a fresh understanding of the moral and ethical dimensions of psychoanalysis requires elaborating a new ontology of human subjectivity and social life. The author offers a sketch of how this gargantuan task might be started by integrating psychoanalysis within a hermeneutic perspective on dialogue, by suggesting that it would be helpful to view psychoanalysis as promoting Aristotelian practical wisdom or phronesis, and by rethinking psychoanalytic theory and interpretation as a form of practice.  相似文献

This study evaluated the effects of three popular physical activities on the psychological well-being of university students. 44 students in three physical activity classes enrolled in the Fitness for Life Program at Montana State University which included circuit training, weight training, and racquetball were administered the Profile of Mood States scale 5 min. before and 5 min. after one bout of physical activity. Two of the three activities appeared to be associated positively with scores on certain subscales. The results supported positive psychological well-being of students after physical activity. Implications for research are presented.  相似文献

Unit recordings and lesion studies have implicated the cerebellum as an essential site for the acquisition and maintenance of the conditioned eyeblink response. The current study looked at the neural characteristics of conditioned stimulus (CS) processing in the interpositus nucleus of the cerebellum after training New Zealand white rabbits (Oryctolagus cuniculus) in one of two conditioning paradigms: (a) compound conditioning (CMP), a compound CS consisting of light and tone paired with an air puff unconditioned stimulus (US); or (b) stimulus compounding (ALT), alternating blocks of tone CS and light CS trials paired with the air puff US. Single unit responses were recorded during five sessions after the animals had reached an asymptotic level of responding. Animals were tested for behavioral and neural responses to CS alone trials that included tone alone, light alone, and compound tone-light trials. For the CMP group, the compound CS elicited 80 to 90% conditioned eyeblink responses (CRs), whereas the individual tone and light CSs elicited only 40 to 50% CRs. For the ALT group, all three CSs (tone, light, and compound) elicited very high levels of responding of at least 80% CRs. For the CMP group, there were roughly equal numbers of cells responding to all of the CSs. This includes cells that responded exclusively to one, and only one, of the three stimuli and also those cells that responded to combinations of two or more. Cells from the ALT group were far more likely to respond exclusively to only one of the CSs. Both the behavioral and physiological results suggest that the compound tone-light stimulus was processed as a distinct stimulus, separate from the component tone and light. These results are discussed in the context of multisensory processing.  相似文献

The Vanderberg-Kuse Mental Rotation Test is a standard test of mental rotation ability. Recent experiments have demonstrated that mental rotation is a complex cognitive process wherein different subprocesses (focused attention, visual scanning, perceptual decision, visual memory) play important roles in performance. We classified the population as good and poor rotators by performance of mental rotation (ns = 47: 22 men and 25 women, respectively; mean age: 20.7 yr.). To examine differences cognitive subprocesses of mental rotation of these two groups were compared. There were significant differences between poor and good rotators in performance on Raven's test and the Pieron Focused Attention test scores. The good rotators scored better because their perceptual decision-analytical intelligence (Raven) and focused attention scores were higher.  相似文献

Categorical perception of facial expressions is studied in high-functioning adolescents with autism, using three continua of facial expressions obtained by morphing. In contrast to the results of normal adults, the performance on the identification task in autistic subjects did not predict performance on the discrimination task, an indication that autistic individuals do not perceive facial expressions categorically. Performance of autistic subjects with low social intelligence was more impaired than that of subjects with higher social IQ scores on the expression recognition of unmanipulated photographs. It is suggested that autistic subjects with higher social intelligence may use compensatory strategies that they have acquired in social training programs This may camouflage the deficits of this subgroup in the perception of facial expressions.  相似文献

Personality Factors and the Short-Term Variability in Subjective Well-Being   总被引:7,自引:0,他引:7  
The present study used a sample of 60 college students and an intensive longitudinal approach to investigate the variability in subjective well-being (SWB). At the beginning of the semester students provided information related to their personalities, while throughout the semester they provided SWB data on a weekly basis. Considerable between-student and within-student variability in SWB was found. Multiple regression analyses revealed that personality-based models were useful in explaining the variability in SWB. Conscientiousness and the Chance component of locus of control were found to be statistically significant independent personality predictors of variability in SWB. Specifically, students high in conscientiousness and high in external locus of control experienced more variability in SWB over the study period.  相似文献
