This paper describes a family who had been known to the professional caring agencies for some five years. At the time of treatment, the family had fifteen-year old twin sons whose frequently aggressive behaviour was the focus of the referred problem. It was agreed that the author would attempt to work with this family should they be re-referred, with a view to offering an alternative mode of treatment. A structural framework of therapy was tried, but very shortly therapeutic attempts to help solve the problems were assimilated by the family and seemed to serve only to ensure their continuation. At this point, a powerful paradoxical intervention was tried in order to free both family and therapists from perpetuating a 'more of the same'. This tactic allowed time for treatment from a more structural base to continue. In this context, consideration is given to the nature of pathological and therapeutic double binding. Some of the difficulties inherent in attempting new methods of treatment from within a traditional casework setting with its statutory responsibilities are also discussed. 相似文献

This paper considers some of the pitfalls of a single-model approach to family therapy. It does not argue a 'right' way of practising family therapy, but proposes that the therapist needs to have available a range of approaches on which to draw. This also raises certain problems for training in family therapy, which are highlighted. A case is discussed in the light of a number of perspectives, to demonstrate how approaches can be used in complementary fashion. Finally, reference is made to some of the agency constraints which also make it difficult to practise any one model in a 'pure' form. 相似文献

When a target stimulus in a predesignated location is identified by a keypress response, responses are slightly faster if noise stimuli in adjacent locations are identical to the target than if they are a different stimulus assigned to the same response (a repeated-stimulus superiority effect). An exception to this result has been found in experiments that used randomly intermixed letter and digit stimuli. These experiments showed slower responding for identical noise than for nonidentical, response-compatible noise (a repeated-stimulus inferiority effect). The present study investigated these phenomena in three experiments. Experiments 1 and 2 established that both the superiority and inferiority effects can be obtained in the same experiment. They also provided evidence that the repeated-stimulus inferiority effect is a function of the intermixing of letters and digits and not of the larger target-set size that has been used for mixed lists. Experiment 3 demonstrated that, with unmixed presentation, the repeated-stimulus superiority effect is enhanced by an increase in the number of stimuli assigned to each response. The experiments are consistent with accounts that attribute the repeated-stimulus superiority effect to competition that occurs when different internal recognition responses are activated. Moreover, the experiments suggest that the repeated-stimulus inferiority effect has its basis in processes that occur subsequent to feature extraction. 相似文献

In sign languages, the task of communicating a shape involves drawing in the air with one moving hand (Method One) or two (Method Two). Since the movement path is iconic, method choice might be based on the shape. In the present studies we aimed to determine whether geometric properties motivate method choice. In a study of 17 deaf signers from six countries, the strongest predictors of method choice were whether the shape has any curved edges (Method One), and whether the shape is symmetrical across the Y‐axis (Method Two), where the default was Method One. In a second study of ASL dictionary entries for which the movement path of the sign is iconic of an entity's shape, the same predictors surfaced. These tendencies are captured in the Lexical Drawing Principle, which is coherent with biological constraints on movement in general. Drawing in the air with two hands, however, is costly, both cognitively and biomechanically. Furthermore, it distinguishes signers from non‐signers, who draw shapes with only one hand. Signers assume this extra cost in the lexicon because of the enhanced iconicity the possibility of two hands offers; they assume it in drawing shapes in the air because they apply the same linguistic principle they use in the lexicon. Additionally, having a choice of methods allows the signer to benefit from over‐specification in providing redundant information about the shape, enhancing comprehensibility and resolving ambiguity. 相似文献
