This paper reviews the literature on performance on standard neuropsychological tests among individuals with posttraumatic stress disorder (PTSD). Of 19 studies, 16 reported impairment of attention or immediate memory (or both); however, most of these studies included PTSD patients with significant psychiatric comorbidity, so that the extent to which the observed deficits are specifically attributable to PTSD remains unclear. Other potential confounds, including medical illness, substance abuse, and motivational factors, further preclude definitive conclusions at present. Results of structural and functional neuroimaging studies of PTSD are also summarized. Two studies have reported correlations between hippocampal volume and cognitive findings in PTSD patients; functional studies have indicated specific findings in limbic regions, although the relationship of these results to neuropsychological performance remains to be explored.  相似文献

This paper outlines a constellation around birth in our society that is related to advanced western medicine and the way that families move around the globe. It describes a brief therapy with a three-year-old child who was diagnosed as autistic, and a mother who resorted to 'heroic' defences against the anxiety of being unsupported in a strange country. The therapist undertook to process the catastrophic experiences of the birth as expressed in the child's play and transform the accompanying monstrous fantasies into human experiences and thoughts. By providing a maternal container for both mother and child, the therapist was able to dissolve the couple's negative enmeshment and help create a space in the mother's mind in which she could process her own feelings, and thereby process and understand the child's feelings and communications.  相似文献

Children with attention deficit hyperactivity disorder (ADHD) are often treated with central nervous system stimulants, making the evaluation of medication effects an important topic for applied behavior analysts. Because assessment protocols emphasize informant reports and direct observations of child behavior, little is known about the extent to which children themselves can accurately report medication effects. Double-blind placebo-controlled procedures were used to examine whether 6 children with ADHD could recognize the effects of their medication. The children were given math worksheets to complete for 15 min during each of 14 sessions while on medication and placebo. Children completed a self-evaluation form at the end of each session, and ratings were compared to observed behavior and academic performance. Results indicated that 3 children were able to accurately report their medication status at levels greater than chance, whereas the accuracy of reports by all children was related to dosage level, differences in behavior, and the presence of adverse effects. The implications of these results for placebo-controlled research, self-monitoring of dosage levels, and accuracy training are discussed.  相似文献

Out of the many aspects of posttraumatic adaptation the role of self-process is emphasized, where self is conceptualized as the representation of social interaction: Not only the messages conveyed by others, but also a person's inner response to that messages, forms ongoing self-processes. Traumatic experiences lead to distorted self-processes, to a great extent due to posttraumatic inner dialogues. Therapeutic implications and experiences from Bosnia are discussed, where this model has been applied.  相似文献

Abstract:  Taking inspiration from a quotation by Lao Tzu, this paper considers 'reverie' as a dynamic process of containment as well as a state of mind. Reverie as a quality of thought akin to prayer is explored in the relationship between self and other. In infant observation, the paper contemplates the development of a baby's capacity to reach beyond the personal world to an archetypal experience of being held, where the creation of an internal space in mind could indicate the beginnings of spiritual awareness. 'Maternal/analytic reverie' views the passage of unconscious communication between patient and analyst as the result of a 'window' opening in the meniscus of the analyst's self. 'Paternal/supervisory reverie' reflects on the impact on a patient of an extra containing mind of a supervisor. 'Archetypal reverie' considers the transforming impact of numinous dreams on the psyche, and reflects on the power of prayer. Drawing on clinical examples from these four areas, the aim is to demonstrate the usefulness of the 'void within' and the perceptive function of emptiness in the 'doors and windows' of our mind.  相似文献

Four experiments examined the role of correlations between dynamic and static parts on 12- to 16-month-olds' ability to learn the identity of agents and recipients in a simple causal event. Infants were habituated to events in which objects with a dynamic or static part acted as an agent or a recipient and then were tested with an event in which the part-causal role relations were switched. Experiment 1 revealed that 16-month-olds, but not 12-month-olds, associate a dynamic part with the role of agent and a static part with the role of recipient. Experiment 2 showed that 12- and 16-month-olds do not associate a static part with the role of agent or a dynamic part with the role of recipient. Experiment 3 demonstrated that 14-month-olds will learn the relations presented in Experiment 1 and Experiment 2. Experiment 4 revealed that 12-month-olds were able to discriminate the two geometric figures in the events. The results are discussed with respect to infants' developing ability to attend to correlations between dynamic and static cues and the mechanism underlying early object concept acquisition.  相似文献

Simultaneous visual discrimination in Asian elephants   总被引:3,自引:0,他引:3  
Two experiments explored the behavior of 20 Asian elephants (Elephas aximus) in simultaneous visual discrimination tasks. In Experiment 1, 7 Burmese logging elephants acquired a white+/black- discrimination, reaching criterion in a mean of 2.6 sessions and 117 discrete trials, whereas 4 elephants acquired a black+/white- discrimination in 5.3 sessions and 293 trials. One elephant failed to reach criterion in the white+/black- task in 9 sessions and 549 trials, and 2 elephants failed to reach criterion in the black+/white- task in 9 sessions and 452 trials. In Experiment 2, 3 elephants learned a large/small transposition problem, reaching criterion within a mean of 1.7 sessions and 58 trials. Four elephants failed to reach criterion in 4.8 sessions and 193 trials. Data from both the black/white and large/small discriminations showed a surprising age effect, suggesting that elephants beyond the age of 20 to 30 years either may be unable to acquire these visual discriminations or may require an inordinate number of trials to do so. Overall, our results cannot be readily reconciled with the widespread view that elephants possess exceptional intelligence.  相似文献

Organizational measurement is necessary for managing incremental improvements or change efforts. Some have argued that indicators of financial performance measure the past and should be joined by "lead" measures such as management development and customer relations, assumed to be drivers of performance. Approaches of "lead" measures have met criticism for not contributing to operational management. The present is an empirical case study where measures from a customer satisfaction survey and a management assessment instrument were analyzed and compared to actual measures of financial performance. The effects of measures obtained seem to depend on the interpretations and reflection taking place in the organization. The pursuit of "lead" indicators did not seem to drive results. Counter-intuitively, higher scores on these measures were related to poorer financial performance. The explication of and reflection on the underlying dynamic seemed to turn the development in a profitable direction.  相似文献

The emergence of human communication systems is typically investigated via 2 approaches with complementary strengths and weaknesses: naturalistic studies and computer simulations. This study was conducted with a method that combines these approaches. Pairs of participants played video games requiring communication. Members of a pair were physically separated but exchanged graphic signals through a medium that prevented the use of standard symbols (e.g., letters). Communication systems emerged and developed rapidly during the games, integrating the use of explicit signs with information implicitly available to players and silent behavior-coordinating procedures. The systems that emerged suggest 3 conclusions: (a) signs originate from different mappings; (b) sign systems develop parsimoniously; (c) sign forms are perceptually distinct, easy to produce, and tolerant to variations.  相似文献
