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.

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

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

The authors present the historical analysis of one of the central questions in psychology: how and why the nonautomatic, psychological level of regulation (in contrast to automatic physiological processes) emerges both in evolution and in everyday context of activity. They discuss several approaches (by Lipps, Groos, Stern, James, Dewey, Claparède, Pavlov, and Leontiev) that culminated in the system of ideas developed by Galperin, one of the key figures in the cultural -historical activity theory. The authors analyze the relation of Galperin's ideas to Vygotsky's theoretical framework and then focus on Galperin's account of the origin and functions of mental activity. Galperin's contribution is highly relevant for understanding the role of psychological regulation and for contemporary research on cognition, consciousness, and conscious awareness.  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

The aim of this work was to obtain an abridged form of the Adolescent Coping Scale (Spanish version) that included items representative of the various factorial dimensions identified as stable. The scale (80 items) was administered to 800 Argentine adolescents. Factor analyses, principal axes and oblimin solution, were performed. An abridged scale was obtained, consisting of 46 items that were grouped into 11 dimensions: Cognitive Redefinition, Self-Blame, Fatalism, Evasion Through Amusement, Problem-Focused Coping (which includes requests for information and action), Evasion Through Physical Activity, Emotional Support, Emotional Discharge and Somatization, Anxiety, Isolation, and No Action. The reliability coefficients were found to be satisfactory.  相似文献

Processing of temporal information: Evidence from eye movements   总被引:1,自引:0,他引:1  
In two experiments, we recorded eye movements to study how readers monitor temporal order information contained in narrative texts. Participants read short texts containing critical temporal information in the sixth sentence, which could be either consistent or inconsistent with temporal order information given in the second sentence. In Experiment 1, inconsistent sentences yielded more regressions to the second sentence and longer refixations of it. In Experiment 2, this pattern of eye movements was shown only by readers who noticed the inconsistency and were able to report it. Theoretical and methodological implications of the results for research on text comprehension are discussed.  相似文献
