National Socialism destroyed the integrity and substance of Psychoanalysis in Germany for a long time to come. The author was among those responsible for the reintroduction of psychoanalytic knowledge and in the organization of psychoanalytic institutions. In this article she tells about the difficulties in reestablishing psychoanalysis in the new Federal Republic, where it met considerable resistance and obstacles. In particular the author gives credit to the significant contribution of German and Austrian emigrants as well as that of psychoanalysis in Anglosaxon countries, especially the London "Schools" of Anna Freud and Melanie Klein.  相似文献

As the analyst makes the correct interpretations of resistance in the opening phase of an analysis, the patient begins to feel understood, often for the first time. This feeling allays anxiety and depressive affects, and the patient comes to experience the analyst as a soother. These initial exchanges may lay the foundation for a positive transference which acts as a buffer against turbulent transferences. In some patients this positive transference develops rapidly, often with prompt symptom remission. In others--children as well as adults--the analyst must persistently interpret defensive regressions before a stable, positive transference can emerge. In either case, in order to avoid the analysis of conflict, some patients become resistant to the analysis of the wish to be soothed. Many of these patients have had a childhood filled with traumatic parental stimulation or rejection. Two clinical accounts illustrate these contentions.  相似文献

This study was designed to investigate the comparability of the original MMPI (1950) and the MMPI-2 (1989) with a psychiatric patient population. 34 male and 3 female patients, shortly after admission to one of two acute psychiatry units, completed the old and revised versions of the MMPI. Paired t tests indicated but scant differences for raw scores, while many more differences were found among T scores for validity, clinical, and supplemental scales. Analyses, however, showed all scales on the two forms to be highly correlated. Analysis of the high-point and two-point codes across the two administrations also showed relative stability, although the proportion of Scales 2 (Depression) and 8 (Schizophrenia) decreased, while those for Scales 6 (Paranoia) and 7 (Psychasthenia) increased markedly in the MMPI-2 protocols. Examination of each version's discriminability among mood- and thought-disordered subsamples suggested that the MMPI provides slightly better delineation between diagnostic classes. Discriminant function analyses showed that there were essentially no differences between the two forms in the accurate classification of clinical and nonclinical groups. The findings reported here provide support for the MMPI-2; despite modification, the newer form retains the advantages of the original MMPI. Differences found here may be unique to psychiatric patients and their patterns of MMPI/MMPI-2 equivalence and may not generalize to other special populations.  相似文献

The purpose of the present study was to investigate differences in demoralization between those who live in single-person households and those who live in households with others in a random sample of 8,634 urban adults. Responses to the 26-item Psychiatric Epidemiologic Research Interview did not substantiate that adults who live alone are more likely to be demoralized than those who live with others, until age and gender are considered. Men who live alone scored higher on demoralization than men who live with others, yet women who live with others scored higher on demoralization than those who live alone. An interaction for living arrangement and age group on demoralization was also observed.  相似文献

Freud revised his theory of dreams significantly. First, he discovered the role of the id in dreaming. He hypothesized that the function of dreaming is to gratify an infantile sexual wish, in accordance with the pleasure principle, and thereby to preserve sleep. However, he learned later that anxiety generated by recent events plays a greater role in stimulating dream formation than he had thought and that some dreams actually generate anxiety. These clinical observations caused him, in large part, to revise his theories of dreaming, of anxiety, and of the mental apparatus.  相似文献

Investigation of the role of 5-hydroxytryptophan (5-HT), which functions as a modulator in the central nervous system, across behavioral contexts suggests that a general principle of transmitter function may be derived that is independent of specific behaviors and specific neural loci. A functional principle of 5-HT action in neural information processing in the central nervous system is proposed. Extremes deviations in 5-HT activity result in biases in information processing that may have direct effects on behavior. Such biases may predispose to pathological conditions such as violent suicide and aggression.  相似文献

In this paper we study the acquisition of German noun plurals in relation to the question of how children represent regular and irregular inflection. Pinker and Prince (1992) have demonstrated several dissociations between regular and irregular inflection in the English past tense system. However, in English, the default status of -ed is confounded with its high frequency; therefore inflectional systems other than English past tense formation must be examined. The noun plural system in German is particularly interesting, because most nouns have irregular plurals in German and the regular (default) plural is less frequent than several of the irregular plurals. Thus it is unclear how a language learner determines whether German even has a regular plural, and if so what form it takes. Based on longitudinal data from impaired and unimpaired monolingual German-speaking children, we find a striking, statistically significant correlation: plural affixes that are used in overregularizations, namely -n or -s, are left out within compounds. This correlation shows that even impaired children are sensitive to the distinction between regular and irregular morphology. We propose a linguistic analysis of the correlation in terms of Kiparsky's (1982, 1985) level-ordering model plus an additional ordering condition on affixes: default (regular) affixes cannot serve as input to compounding processes.  相似文献

In this paper we address the question how in language production conceptual structures are mapped onto lexical items. First we describe the lexical system in a fairly abstract way. Such a system consists of, among other things, a fixed set of basic lexical entries characterized by four groups of information: phonetic form, grammatical features, argument structure, and semantic form. A crucial assumption of the paper is that the meaning in a lexical entry has a complex internal structure composed of more primitive elements (decomposition). Some aspects of argument structure and semantic form and their interaction are discussed with respect to the issue of synonymy. We propose two different mappings involved in lexical access. One maps conceptual structures to semantic forms, and the other maps semantic forms to conceptual structures. Both mappings are context dependent and are many-to-many mappings. We present an elaboration of Levelt's (1989) model in which these processes interact with the grammatical encoder and the mental lexicon. Then we address the consequences of decomposition for processing models, especially the nature of the input of lexical access and the time course. Processing models that use the activation metaphor may have difficulties accounting for certain phenomena where a certain lemma triggers not one, but two or more word forms that have to be produced with other word forms in between.  相似文献

Recent studies, mostly performed on bulimic outpatients, did not find consistent predictors of treatment outcome in bulimia nervosa. This is the first study to investigate anamnestic and clinical factors predictive of the short-term outcome of hospital treatment in 31 female bulimia nervosa patients with a mean age of 22.9 yr. Treatment outcome was assessed by several self-rating instruments measuring different features of the specific and unspecific psychopathology of bulimia nervosa. The most relevant predictors of the outcome of the 8-week hospital treatment were duration of previous inpatient treatments for bulimia, the intensity of anorexic tendency and the pretreatment level of depression. The majority of predictors tested did not show a strong relationship to treatment outcome. The findings are discussed in relation to results of other studies as well as to possible implications for treatment and research.  相似文献
