The patterns of interaction between analyst and analysand are discussed with special reference to the participation of both analyst and analysand in the analytic dialogue. The analyst's participation and interaction with the analysand can take place in one or all of the threefold constituents of the analytic relation—transference (and countertransference), real relation, and alliance. Although these components are continually present and mutually interactive in the analytic process, they can be differentiated in the diversity of patterns of interaction and their implications for technical aspects of the analytic process. Although transference and countertransference hold the primary place in analytic interest, other aspects deserve proper emphasis and exploration insofar as they make substantive and significant contributions to the effectiveness or ineffectiveness of the analytic process. The nature and quality of their influence on patterns of interaction are discussed as well as implications of their respective roles in the analytic process.

As laboratorians relate analytic performance to medical goals, they face complex choices among competing subjective and objective criteria for the assessment of acceptable analytic error. Defining desirable performance as some fraction of physiologic variability provides potentially excessive benchmarks for quality. More important than the recognition of health are the clinical decisions which deal with diseases, particularly the latters' degrees of severity and the different medical actions these prompt. It is equally essential to take into account the reasoning by which physicians arrive at these decisions, since their mental processes condition desirable performance goals. Considering these modalities, a universal model of analytic performance requirements uniformly applicable to all measured parameters clearly cannot be devised. Rather, tolerance limits for analytic error must be tailored to specific medical problems. To facilitate this seemingly Herculean task, this paper develops concepts and principles derived from operation research, and illustrates their application by three examples. The generic conclusion evidenced by the latter is that the linkage between analytic performance goals and medical strategies is reciprocal, namely that outcome can just as well be optimized by tailoring medical strategy to existing analytic performance as by adapting analytic performance to medical strategy.  相似文献

In this article the author discusses the problems and dilemmas created by patients who are chronically late for analytic hours or frequently absent from them. The discussion focuses on a single case study, in which this phenomenon was a predominant feature of the analytic process. The author explores some of the issues, dynamic and defensive, underlying such behavior as well as motivational components involving unresolved oedipal issues and powerful unsatisfied narcissistic needs. The temporal difficulties of patients such as this one demonstrate the role of time as a point of conjunction of aspects of the analytic relation involving the temporal dimension of the real structure of the analytic situation and its intersection with transferential and alliance considerations. The analytic task is to balance the temporal requirements of the analytic process against the array of the patient's infantile and narcissistic needs on one hand and legitimate claims for autonomy and freedom on the other.

There is a notable lack of interest in the daydream, whether in clinical work, in the literature, or in psychoanalytic teaching, compared with the attention received by nocturnal dreams, fantasy activity, and other psychoanalytic material. This neglect of daydreams may be related to the apparent infrequency with which patients report them in analytic treatment. Possible explanations for the unavailability of daydreams as analytic material are examined. The paper offers detailed clinical material that will provide some of the necessary analytic data with which to begin an exploration of the nature of daydreams and their role in the analytic process.  相似文献

Introduction.     
The editor of this special issue on child analytic work briefly characterizes the focus of the included works. This special issue on child analytic work contains articles on child psychoanalysis, childhood play, the role of the parent in child work, and the analytic process. Two book reviews complete the picture. Child psychoanalysis richly rewards us and stimulates us toward continuous exploration, development, and understanding.

With the use of the criterion of privileged axes, 6 experiments with 96 undergraduates showed that analytic processing of saturation and brightness, prototypical integral dimensions, does sometimes occur. However, it was less frequent and less successful than the analytic processing of separable dimensions. Findings identify several factors that influence whether analytic processing occurs: (a) stimulus factors such as the magnitude of dimensional differences; (b) task factors, including the degree to which analytic processing is encouraged by instructions or by implicit task demands and the amount of time available for processing; and (c) S factors, particularly the amount of experience that the perceiver has had with the stimuli in tasks that encourage stimulus analysis.
