This paper describes the psychotherapy of a patient whose treatment had an effect of overtaxing the emotional capability of the therapist to bear the work. The patient experienced efforts to contain her violent reactions as an annihilation and repetition of the most injurious actions of her caregivers in her childhoodPlease check the given section headings are ok.Please provide Organization/University name to add in the corresponding details of the author “Stuart D. Perlman”. The therapist provided special responses, inspired by the work of Sándor Ferenczi, which were found to help the patient discriminate between her parents and the therapist and begin a healing process.  相似文献

The paper identifies aspects of subtle social aggression in the school environment that can make children and staff feel quite miserable and unsafe, and which will thus likely impair a child's capacity to learn, and a teacher's capacity to teach. Unaddressed power dynamics created by the interaction and attitudes of those in the social context are defined, and the interpersonal dynamics of the abdicating bystander described. A randomized controlled trial of an intervention for elementary schools is described briefly, which attempts to modify social aggression.  相似文献

The aim of this essay is to establish the logically necessary preconditions for the existence of self-awareness in an artificial or a natural agent. It examines the terms agent , situated , embodied , embedded , and representation as employed ubiquitously in cognitive science, attempting to clarify their meaning and the limits of their use. It discusses the minimal conditions for an agent's environment constituting a 'world' and rejects most, though not all, types of virtual world. It argues that to qualify as genuinely situated an agent should function in real time within the dynamic world we inhabit, or some close simulacrum of it. It shows that embodied agents will possess or evolve local coordinate systems, or points of view, locating, identifying, and interacting with objects relative to their current position in space-time, and it discusses various types of embodiment, arguing that most current situated and embodied systems are too limited to be candidates for even the most minimal claim to self-identity. It argues that a truly autonomous agent has to be active in its participation with the world, able to synthesize and order its internal representations from its own point of view, and that to do this effectively the agent will have to be embedded. To this end it proposes a six-point definition of embeddedness. Ultimately it argues for a philosophical-cum-cognitive-science model of the self that satisfies essential elements of both sets of definitions of the term.  相似文献

The relation between reaction time and the number of elements in a response has been shown to depend on whether simple or choice RT paradigms are employed. The purpose of the present study was to investigate whether advance information about the number of elements is the critical factor mediating the influence between reaction time and response elements. Participants performed aiming movements that varied in terms of the number of elements and movement amplitude. Prior to the stimulus, advance information was given about the number of elements and movement amplitude, movement amplitude only, number of elements only, or no information about the response. Reaction time and movement time to the first target increased as a function of number of elements only when the full response or the number of elements was specified in advance of the stimulus. The implication of these results for current models of motor programming and sequential control of aiming movements are discussed.  相似文献

Matching methods such as nearest neighbor propensity score matching are increasingly popular techniques for controlling confounding in nonexperimental studies. However, simple k:1 matching methods, which select k well-matched comparison individuals for each treated individual, are sometimes criticized for being overly restrictive and discarding data (the unmatched comparison individuals). The authors illustrate the use of a more flexible method called full matching. Full matching makes use of all individuals in the data by forming a series of matched sets in which each set has either 1 treated individual and multiple comparison individuals or 1 comparison individual and multiple treated individuals. Full matching has been shown to be particularly effective at reducing bias due to observed confounding variables. The authors illustrate this approach using data from the Woodlawn Study, examining the relationship between adolescent marijuana use and adult outcomes.  相似文献
