The structure of depressive symptom patterns was investigated in a community sample of 344 women between the ages of 51 and 92 who were administered the SCL-90-R Depression and Additional Symptoms Scales. Confirmatory factor analysis was used to test alternative measurement hypotheses implied by clinical formulations of depressive symptom patterns among elderly persons. The findings show support for the hypothesis that 2 somewhat different depressive syndromes, along with 4 more delimited forms of distress, underlie symptom-reporting patterns. Implications of these findings for future research on the relation between aging and depression are discussed.  相似文献

Twenty normotensive subjects participated on a voluntary basis in an experiment designed to study the effects of specific suggestions on blood pressure (BP). After an induction procedure, the experimental group received suggestions presumed to be relatively nonactivating, although capable of lowering or raising BP. A control group was used to record the BP changes over time. All subjects met for one session. Eight subjects from the experimental group met for a second session. Both adaptation and induction resulted in significant BP decreases. A specific suggestion to increase BP gave a significant result when compared to the induction point. There was no significant change from induction to the BP decrease suggestion. Both systolic and diastolic BP behaved in the same way. A second experimental session resulted in no significant change compared with the first session. Also, no significant difference was found in suggestibility scores from the first to the second session. The results are in line with previously published studies.  相似文献

Abstract. The shift from a pre-Copernican to a Copernican world view has caused an ever increasing sense of homelessness for the idea of a theistically conceived God. This paper first traces the historical development of this problem and its implications for the Christian faith. Next it presents some historically evolved "rescue" attempts and examines them critically. Then follows an inquiry concerning the biblical understanding of God's relation to space and a critical presentation of some contemporary proposals to make God's presence intelligible. In conclusion we propose a dimensional model of relating God and the world, a model which allows for a reasonable discourse of God's immanence and transcendence.  相似文献

This paper dwells upon formal models of changes of beliefs, or theories, which are expressed in languages containing a binary conditional connective. After defining the basic concept of a (non-trivial) belief revision model. I present a simple proof of Gärdenfors's (1986) triviality theorem. I claim that on a proper understanding of this theorem we must give up the thesis that consistent revisions (additions) are to be equated with logical expansions. If negated or might conditionals are interpreted on the basis of autoepistemic omniscience, or if autoepistemic modalities (Moore) are admitted, even more severe triviality results ensue. It is argued that additions cannot be philosophically construed as parasitic (Levi) on expansions. In conclusion I outline somed logical consequences of the fact that we must not expect monotonic revisions in languages including conditionals.I wish to thank Peter Gärdenfors for a number of helpful comments, André Fuhrmann and Wolfgang Spohn for extensive discussion of parts of this paper, and Winfred Klink for kindly checking my English.  相似文献

Summary The Structural Memory, a network model for human perception of serial objects, such as series, is presented. Our theoretical assumptions originate from the Structural Information (Theory (SIT) (Buffart & Leeuwenberg, 1983; Leeuwenberg, 1969), a theory concerning the perceptible structures in an object and the human preference for one of these structures. A symbolic notation of such a perceptible structure in an object is called a representation. For a given maximum number of symbols we can generate all representations automatically. From this procedure we define G(eneration)-relations between the representations. We also define S(tructure)-relations based upon the structures described by the representations. The representations and relations can be seen as respectively the nodes and links in a network. This network is the basis for the Structural Memory. We therefore assign an activation value to each representation in the network, expressing the strength of the preference for the described structure at a certain moment. By means of a process model we are able to make predictions for the strength of the preference for a perceptible structure in an object. The process is only based upon the network structure, because of a relation found between the preference measure, used in SIT, for a perceptible structure in an object and the number of G- and S-relations of the corresponding representation in the network. It is shown that with two of these process models some experiments by Van Leeuwen and Buffart can be simulated.  相似文献

Background

Since 2010 a total of 15 individually justified, therapeutically accompanied treatment-free intervals from antiandrogenic treatment (ADT) have been carried out in the Forensic Therapeutic Outpatient (FTA) department in Berlin.

Material and methods

This article describes the conditions under which a responsible and legally justifiable cessation of ADT can be carried out.

Results

In all 15 of the investigated stable, forensically rehabilitated patients who had been on long-term psychotherapeutic treatment, no criminally prognostic or clinically relevant destabilization has so far occurred, which would have necessitated cessation of the treatment-free interval with resumption of the antiandrogenic depot medication.

Conclusion

The short-term experiences from the clinical aftercare practice have so far shown that in a strictly structered aftercare setting with continuous clinical monitoring, it is possible to withdraw even long-standing antiandrogenic medication. This is important not least to attest the argumentation for a removal of supervision of conduct in case destabilization does occur. Further long-term longitudinal investigations will be the subject of later publications.

Both phonological and phonetic priming studies reveal inhibitory effects that have been interpreted as resulting from lexical competition between the prime and the target. We present a series of phonetic priming experiments that contrasted this lexical locus explanation with that of a prelexical locus by manipulating the lexical status of the prime and the target and the task used. In the related condition of all experiments, spoken targets were preceded by spoken primes that were phonetically similar but shared no phonemes with the target (/bak/–/dεt/). In Experiments 1 and 2, word and nonword primes produced an inhibitory effect of equal size in shadowing and same–different tasks respectively. Experiments 3 and 4 showed robust inhibitory phonetic priming on both word and nonword targets in the shadowing task, but no effect at all in a lexical decision task. Together, these findings show that the inhibitory phonetic priming effect occurs independently of the lexical status of both the prime and the target, and only in tasks that do not necessarily require the activation of lexical representations. Our study thus argues in favour of a prelexical locus for this effect.  相似文献

We here present the development and validation of the Verbal Affective Memory Test-24 (VAMT-24). First, we ensured face validity by selecting 24 words reliably perceived as positive, negative or neutral, respectively, according to healthy Danish adults’ valence ratings of 210 common and non-taboo words. Second, we studied the test's psychometric properties in healthy adults. Finally, we investigated whether individuals diagnosed with Seasonal Affective Disorder (SAD) differed from healthy controls on seasonal changes in affective recall. Recall rates were internally consistent and reliable and converged satisfactorily with established non-affective verbal tests. Immediate recall (IMR) for positive words exceeded IMR for negative words in the healthy sample. Relatedly, individuals with SAD showed a significantly larger decrease in positive recall from summer to winter than healthy controls. Furthermore, larger seasonal decreases in positive recall significantly predicted larger increases in depressive symptoms. Retest reliability was satisfactory, rs?≥?.77. In conclusion, VAMT-24 is more thoroughly developed and validated than existing verbal affective memory tests and showed satisfactory psychometric properties. VAMT-24 seems especially sensitive to measuring positive verbal recall bias, perhaps due to the application of common, non-taboo words. Based on the psychometric and clinical results, we recommend VAMT-24 for international translations and studies of affective memory.  相似文献
