Quarreling couples caught in destructive patterns of communication often cause difficult situations during couple therapy. Such communication patterns range from pure verbal humiliation and insults up to outbursts of violence. In order to remain capable of therapy, psychotherapists must know the underlying mechanisms that provoke and maintain the destructive viscious circles. Moreover, they must have at their disposal the required explanatory ideas and practical intervention strategies for de-escalation and interruption of these destructive patterns. 相似文献

The current debate in medical ethics on placebos focuses mainly on their use in health research. Whereas this is certainly
an important topic the discussion tends to overlook another longstanding but nevertheless highly relevant question, namely
if and how the placebo effect should be employed in clinical practice. This paper describes the way the placebo effect is
perceived in modern medicine and offers some historical reflections on how these perceptions have developed; discusses elements
of a definition of the placebo effect; and suggests some conditions under which making use of the therapeutic potential of
the placebo effect can be ethically acceptable, if not warranted.
An earlier version of this paper was presented at an international conference, “Placebo: Its Action and Place in Health Research
Today,” held in Warsaw, Poland on 12–13 April, 2003.

In adults, three phenomena are taken to demonstrate an experience effect on face recognition: an inversion effect, a non-native face effect (so-called 'other-race' effect) and their interaction. It is crucial for our understanding of the developmental perception mechanisms of object processing to discover when these effects are present in childhood. Three- to 5-year-old Caucasian children (N = 64) were asked to recognize upright and inverted Caucasian and Asian faces. Recognition was tested with a forced-choice procedure. Overall performance improved with age. However, there was an interaction between the inversion and non-native effects that did not change with age between ages 3 and 5: (a) the inversion effect with native (Caucasian) faces was larger than with non-native (Asian) faces, and (b) upright native faces were recognized better than upright non-native faces. These results show that face orientation and morphology constrain face processing in 3- to 5-year-olds. The first 3 years of life during which the brain and the environment interact are sufficient to build a face-processing system that constrains recognition. 相似文献

Zusammenfassung Untersuchungen zu Häufigkeit, Verlauf und Ursachen psychischer Erkrankungen bei Arbeitnehmern sind rar. Die Gründe hierfür liegen sowohl auf Seiten der Arbeitsmedizin, die psychosoziale Aspekte wenig berücksichtigt, als auch bei der Psychotherapie, die zu wenig auf die Arbeitssituation eingeht. Die wenigen aussagekräftigen Untersuchungen legen bei Arbeitnehmern eine ähnlich hohe Prävalenz und Behandlungsbedürftigkeit nahe wie in der Allgemeinbevölkerung. Von den Folgen einer störungsinadäquaten Therapie psychischer Erkrankungen sind Arbeitnehmer in besonderem Maße betroffen, da die Erkrankungen nicht nur zu erheblichem persönlichem Leid führen, sondern durch Chronifizierung zu enormen Kosten in der medizinischen Versorgung beitragen. Außerdem sind sie durch krankheitsbedingte Fehlzeiten und (Früh-)Berentungen auch die Ursache weit reichender Produktionsausfälle in der Wirtschaft. Obwohl eine Reihe von Maßnahmen der betrieblichen Gesundheitsförderung zur Besserung der psychischen Befindlichkeit von Arbeitnehmern verfügbar sind, werden sie gegenwärtig noch zu selten eingesetzt und noch weniger evaluiert.

Valence of distractor words increases the effects of irrelevant speech on serial recall 总被引:3,自引:0,他引:3
Participants memorized target words in silence or while ignoring neutral or valent (positive or negative) distractor words that could be either possessor-relevant or other-relevant. Distractor words impaired recall performance, but valent distractor words caused more disruption than neutral distractors, and negative distractors caused more disruption than positive distractors. The results are problematic for explanations of the irrelevant speech effect within working memory models that do not specify an explicit role of attention in the maintenance of information for immediate serial recall. 相似文献

On doing two things at once: Temporal constraints on actions in language comprehension 总被引:1,自引:0,他引:1
In two experiments, we investigated how text comprehension is influenced by the interaction between the properties of actions and the temporal relations specified by adverbs. Participants read short narratives describing a protagonist who performed two actions that involved similar sensorimotor systems (e.g., chopping wood and painting a fence) or different ones (e.g., whistling a melody and painting a fence). The actions were described as simultaneous or successive by means of the temporal adverbs while and after, respectively. Comprehension, both in Spanish and in English, was markedly impaired (longer reading times and lower subjective coherence) for sentences including the adverb while and actions involving the same sensorimotor system. However, when one of the same sensorimotor system actions was described as a mental plan (e.g., chopping wood and thinking of painting a fence), comprehension was equally easy with the adverbs while and after. These results are compatible with a revised version of the indexical hypothesis that specifies how comprehension is guided by syntax and embodied constraints within multiple noninteracting mental spaces. 相似文献

The male-offspring biased visual kin recognition in chimpanzees (Pan troglodytes) reported by L. A. Parr and F. B. M. de Waal (1999) was replicated with human (Homo sapiens) participants and a principal components analysis (PCA) of pixel maps of the chimpanzee face photos. With the same original materials and methods, both humans and the PCA produced the same asymmetry in kin recognition as found with the chimpanzees. The PCA suggested that the asymmetry was a function of differences in the distribution of global characteristics associated with the framing of the faces in the son and daughter test sets. Eliminating potential framing biases, either by cropping the photos tightly to the faces or by rebalancing the recognition foils, eliminated the asymmetry but not human participants' ability to recognize chimpanzee kin. 相似文献

Dogs can use a variety of experimenter-given cues such as pointing, head direction, and eye direction to locate food hidden under one of several containers. Some authors have proposed that this is a result of the domestication process. In this study we tested four captive fur seals in a two alternative object choice task in which subjects had to use one of the following experimenter-given cues to locate the food: (1) the experimenter pointed and gazed at one of the objects, (2) the experimenter pointed at only one of the objects, (3) the experimenter gazed at only one of the objects, (4) the experimenter glanced at only one of the objects, (5) the experimenter pointed and gazed at one of the objects but was sitting closer to one object than to the other, (6) the experimenter pointed only with the index finger at one of the objects, (7) the experimenter presented a replica of one of the objects. The fur seals were able to use cues which involved a fully exposed arm or a head direction, but failed to use glance only, the index finger pointing and the object replica cues. The results showed that a domestication process was not necessary to develop receptive skills to cues given by an experimenter. Instead, we hypothesize that close interactions with humans prior to testing enabled fur seals to use some gestural cues without formal training. We also analyzed the behavior of the seals depending on the level of difficulty of the task. Behavioral signs of hesitation increased with task difficulty. This suggests that the fur seals were sensitive to task difficulty. 相似文献
