Entstehung und Verlauf der Panikstörung

Zusammenfassung Das Konzept der Panikstörung ging ursprünglich auf neurobiologische Modellvorstellungen zurück, die rasch von verhaltenstherapeutischen Ansätzen aufgegriffen und differenziert wurden, während die Rezeption durch psychoanalytische Ansätze zurückhaltend erfolgte. In dieser Übersicht werden aktuelle neurobiologische, verhaltenstherapeutische und psychodynamische Modelle dargestellt. Neurobiologische Ansätze beschreiben die zentrale und periphere Fehlsteuerung des Stresshormonsystems. Verhaltenstherapeutische Modelle erklären die Aufrechterhaltung der Störung durch konditionierte Furchtreaktionen, Fehlinterpretation körperlicher Sensationen bzw. dispositionale Angstsensitivität. Neuere psychodynamische Konzepte beschreiben mangelnde Toleranz für intensive Affekte und Trennungserfahrungen aufgrund unsicherer Objektbeziehungsrepäsentanzen als Ursachenfaktoren für Panik. Sie schaffen damit Verbindungen zu tierexperimentellen und neurobiologischen Studien, die die Bedeutung vorzeitiger Trennungserfahrungen für lebenslang erhöhte Stressreagibilität und Furchtsamkeit herausgearbeitet haben. Neurobiologische, verhaltenstherapeutische und psychodynamische Ansätze ergänzen sich beim Verständnis dieses heterogenen Krankheitsbildes.     

The implicit association test as a general measure of similarity.

The Implicit Association Test (IAT) is widely used as a measure of semantic similarity (i.e., associations in semantic memory). The results of previous research and of a new study show that IAT effects can, however, also be based on other types of similarity between stimuli. We therefore put forward the hypothesis that the IAT provides a general measure of similarity. Given that similarity is highly dynamic and context-dependent, our view that the IAT measures similarity is compatible with existing evidence showing that IAT effects are highly malleable. We provide further evidence for this in a new study in which the outcome of an IAT depended on whether the perceptual or functional characteristics of the stimuli were made salient.     

Implicit attentional orienting in a target detection task with central cues

Studies using Posner’s spatial cueing paradigm have demonstrated that participants can allocate their attention to specific target locations based on the predictiveness of preceding cues. Four experiments were conducted to investigate attentional orienting processes operating in a high probability condition (cues 75% predictive) as compared to a low probability condition (cues 50% predictive) using various types of centrally-presented cues. Spatially-informative cues (arrows and circles with gaps) resulted in cueing effects (CEs) for both probability conditions, with significantly larger CEs in the high probability conditions than the low probability conditions. Participants in the high probability conditions reported little or no awareness of cue–target probabilities after task completion. Our results provide support for an implicit learning account of the proportion valid effect under experimental conditions involving spatially-informative central cues and relatively short stimulus onset asynchronies (SOAs).     

Analogical insight: toward unifying categorization and analogy

The purpose of this paper is to present two kinds of analogical representational change, both occurring early in the analogy-making process, and then, using these two kinds of change, to present a model unifying one sort of analogy-making and categorization. The proposed unification rests on three key claims: (1) a certain type of rapid representational abstraction is crucial to making the relevant analogies (this is the first kind of representational change; a computer model is presented that demonstrates this kind of abstraction), (2) rapid abstractions are induced by retrieval across large psychological distances, and (3) both categorizations and analogies supply understandings of perceptual input via construing, which is a proposed type of categorization (this is the second kind of representational change). It is construing that finalizes the unification.     

A formal framework for modelling the developmental course of competence and performance in the distance,speed, and time domain

The developmental course in the distance–speed–time domain is still a matter of debate. Traditional stage models are contested by theories of continuous development and adaptive thinking. In the present work, we introduce a formal framework for modelling the developmental course in this domain, grounding on Competence-based Knowledge Space Theory. This framework, as a more general case, widely includes assumptions and facets of previous models and covers empirical findings collected based on different experimental paradigms. By a distinction of latent competences and observable performance, model validation is not bound to a certain experimental paradigm and no one-to-one correspondence between competences and tasks is required. Therefore, the framework has the potential to bridge the gap between stage models and models of continuous development. The approach also precisely defines misconceptions, for example overgeneralization, and empirically investigates their occurrence. In the present work, we established a prototypical model for the development of understanding the distance–speed–time system. We extended this model with definitions based on different perspectives of overgeneralization. The assumptions of the model and its extensions were examined on the basis of the results of two empirical investigations using six judgment task types. The results yielded a reasonably good fit of model and data. No evidence was found for the occurrence of overgeneralization in this domain. The theoretical model and empirical results are discussed with respect to their relationship to other developmental models and theories.     

Positive and negative effects of family involvement on work-related burnout

We aimed to explain the influence of family involvement on feelings of burnout among employees who combine work and family tasks. As proxies for family involvement, we used the family structure (partner, number and age of children) and family tasks (e.g. hours spent on household chores). We compared conflict theory and enrichment theory, and investigated how well they explain the relationship between family involvement and feelings of burnout. Based on a sample of 1046 employees at 30 Dutch organizations, the results showed that the presence of young children and doing more household chores were positively related to feelings of burnout, whereas having children reduced employees’ feelings of burnout. We also investigated interaction effects of gender and gender-role norms. We conclude that family life can reduce work-related burnout and that for men, the relationship between family involvement and feelings of burnout differs depending on whether they have traditional or modern gender-role norms.     

Social environment and reproduction in female European rabbits (Oryctolagus cuniculus): benefits of the presence of litter sisters

The authors investigated in an observational study the consequences of the presence of litter sisters on the social interactions and on reproductive performance of young female European rabbits (Oryctolagus cuniculus) from a population living under seminatural conditions. In early winter, when all young females were settled in a social group, they were characterized by the presence or absence of litter sisters in their groups. Females with litter sisters in their groups displayed significantly more positive social interaction with females of their social group compared to females without sisters, whereas this difference was mainly due to the high frequency of positive social interactions among the respective sisters. Such differences between the females of both categories were already apparent during the animals' juvenile phase, before the females integrated into a particular group: females which later had litter sisters in their group showed more positive social behavior than females which later no longer had litter sisters. During their first breeding season, females with litter sisters present generally started to breed earlier by an average of 14 days. A more favorable social environment might have possibly facilitated the earlier onset of breeding in females with present litter sisters by attenuating the negative consequences of stress.     

Redemptive Experience in Relational Family Therapy: A Christian Perspective

We all long for relationships with others, because only in connecting with others can we develop our intrapsychic structure and become functional adults. We are psychologically predisposed to have a constant connection with others and are driven toward relationships with others. Our deepest yearnings are therefore devoted to building solid dialogue as the means of becoming fully human. We, therefore, consciously or unconsciously, long for a relationship where we can experience happiness, satisfaction and, above all, redemption or salvation from our dreads, miseries and unhappiness. In this article we presuppose that a therapeutic relationship, demonstrated in a psychoanalytic setting, namely in relational family therapy, can contain redemptive dimensions in which the inextinguishable longing for salvation is always present.

Ego depletion and aggressive behavior: Is the inhibition of aggression a limited resource?

If self‐regulation is a limited resource, the capacity to inhibit aggressive behavior should be lower among people who have already exercised self‐regulation. In Experiment 1, participants who had to resist the urge to eat tempting food later reacted more aggressively to an insult than other participants who were allowed to eat as much as they wanted. In Experiments 2 and 3, some participants had to self‐regulate by making themselves concentrate on a boring film and stifling their physical and facial movements, and afterward they, too, responded more aggressively than controls. Experiment 3 also showed that the results were not due to differential moods and that one act of self‐regulation (unrelated to aggression) was sufficient to enhance subsequent aggressive responses toward the experimenter.

When accurate and inaccurate eyewitnesses look the same: a limitation of the ‘pop‐out’ effect and the 10‐ to 12‐second rule

Research has found support for a ‘pop‐out effect’ that occurs when witnesses who accurately identify a criminal from a lineup are faster and uses more automatic processing than inaccurate witnesses who misidentify a foil. We present evidence that this finding may not occur with biased lineups. Witnesses to a mock theft were asked to make a lineup identification and three types of witnesses were compared: (1) accurate witnesses who identified a thief, (2) inaccurate witnesses who misidentified a foil who was more similar looking to the thief than the other lineup foils and (3) inaccurate witnesses who misidentified a foil who was not more similar in appearance to the thief than the other lineup foils. Accurate witnesses who identified the thief and inaccurate witnesses who misidentified a foil more similar to the thief than the other lineup foils were indistinguishable; both were faster, used more automatic recognition processes and were more confident than inaccurate witnesses who identified other foils.
