Psychodynamische Kurzzeittherapie bei dependenter und vermeidender Persönlichkeitsstörung

Although dependent and avoidant personality disorders are frequent in patient populations, there are only few studies in which the efficacy of psychotherapeutic interventions for these two personality disorders was reviewed. The purpose of this study was to examine whether psychodynamic short-term therapy based on the model of the cyclic maladaptive pattern (CMP) is effective for reducing the mental impairment of patients diagnosed with a dependent or an avoidant personality disorder. Data were collected via a self-report scale (Symptom-Checklist, SCL) and expert ratings by therapists [Global Assessment of Functioning (GAF) Scale and Severity of Impairment-Score (Beeinträchtigungsschwere-Score, BSS)]. In the study 20 patients received 25 sessions of outpatient therapy. Mental impairment decreased significantly from the beginning to the end of the therapy; moreover this decrease remained stable over a 2-year period following completion of the therapy. The findings show that psychodynamic short-term therapy can lead to an enduring improvement in the mental health of patients with a dependent or an avoidant personality disorder.     

The anchoring bias reflects rational use of cognitive resources

Cognitive biases, such as the anchoring bias, pose a serious challenge to rational accounts of human cognition. We investigate whether rational theories can meet this challenge by taking into account the mind’s bounded cognitive resources. We asked what reasoning under uncertainty would look like if people made rational use of their finite time and limited cognitive resources. To answer this question, we applied a mathematical theory of bounded rationality to the problem of numerical estimation. Our analysis led to a rational process model that can be interpreted in terms of anchoring-and-adjustment. This model provided a unifying explanation for ten anchoring phenomena including the differential effect of accuracy motivation on the bias towards provided versus self-generated anchors. Our results illustrate the potential of resource-rational analysis to provide formal theories that can unify a wide range of empirical results and reconcile the impressive capacities of the human mind with its apparently irrational cognitive biases.     

Cell phone-induced ostracism threatens fundamental needs

Cell phones are useful tools with both practical and social benefits. However, using them in the context of face-to-face conversations may be problematic. We consider this behavior a form of ostracism and test its effects on the satisfaction of basic psychological needs for belonging, self-esteem, control, and meaningful existence. In Study 1 participants who recalled a time in which a friend was checking a cell phone during a serious conversation reported feeling more ostracized (ignored and excluded), greater pain, and threat to basic needs than participants recalling a conversation without a cell phone interruption or a control event. Study 2 replicated and extended this effect: Cell phone-induced ostracism’s effects were partially mediated by decreased feelings of relational evaluation, and threatened basic needs both in serious and casual conversation contexts. Findings from both studies also indicated that cell phone-induced ostracism hurts women more so than men.     

The development of a Spanish language version of the Worn Out scale of the General Well-Being Questionnaire (GWBQ)

The paper describes the development of a short Spanish-language version of the General Well-Being Questionnaire (GWBQ; Cox and Gotts, 1987), based on the 12 items of its Worn Out scale. Research has shown the English-version Worn Out scale to be sensitive to aspects of the design and management of work. This study aimed to test its cross-cultural consistency in a Spanish-language workplace context. The data were collected from a sample of 229 workers in Valencia (Spain). Confirmatory Factor Analyses showed the factorial validity, reliability, and concurrent validity of the new Spanish version to be adequate. The sensitivity of the new measure to safety behavior and the reporting of accidents was also assessed and shown to be good. The new questionnaire extends the usefulness of the parent questionnaire to occupational health psychology research in the Spanish language by offering a short assessment tool appropriate for workplace studies.     

Probabilistic inference in human semantic memory

The idea of viewing human cognition as a rational solution to computational problems posed by the environment has influenced several recent theories of human memory. The first rational models of memory demonstrated that human memory seems to be remarkably well adapted to environmental statistics but made only minimal assumptions about the form of the environmental information represented in memory. Recently, several probabilistic methods for representing the latent semantic structure of language have been developed, drawing on research in computer science, statistics and computational linguistics. These methods provide a means of extending rational models of memory retrieval to linguistic stimuli, and a way to explore the influence of the statistics of language on human memory.     

Rhythm deficits in 'tone deafness'

It is commonly observed that 'tone deaf' individuals are unable to hear the beat of a tune, yet deficits on simple timing tests have not been found. In this study, we investigated rhythm processing in nine individuals with congenital amusia ('tone deafness') and nine controls. Participants were presented with pairs of 5-note sequences, and were required to detect the presence of a lengthened interval. In different conditions the sound sequences were presented isochronously or in an integer-ratio rhythm, and these were either monotonic or varied randomly in pitch. It was found that the 'tone deaf' participants exhibited inferior rhythm analysis for the sequences that varied in pitch compared to those that did not, whereas the controls obtained equivalent thresholds for these two conditions. These results suggest that the rhythm deficits in congenital amusia result from the pitch-variations in music.     

Modeling human performance in statistical word segmentation

The ability to discover groupings in continuous stimuli on the basis of distributional information is present across species and across perceptual modalities. We investigate the nature of the computations underlying this ability using statistical word segmentation experiments in which we vary the length of sentences, the amount of exposure, and the number of words in the languages being learned. Although the results are intuitive from the perspective of a language learner (longer sentences, less training, and a larger language all make learning more difficult), standard computational proposals fail to capture several of these results. We describe how probabilistic models of segmentation can be modified to take into account some notion of memory or resource limitations in order to provide a closer match to human performance.     

Naturalistic Fallacy Errors and Behavioral Science News: The Effects of Editorial Content and Cautions on Readers' Moral Inferences and Perceptions of Contributors

People commonly overestimate the intensity of their emotions toward future events. In other words, they display an impact bias. This research addresses the question whether people learn from their experiences and correct for the impact bias. We hypothesize that athletes display an impact bias and, counterintuitively, that increased experience with an event increases this impact bias. A field study in the context of competitive track athletics supported our hypotheses by showing that athletes clearly overestimated their emotions toward the outcome of a track event and that this impact bias was more pronounced for negative events than for positive events. Moreover, with increased athletic experience this impact bias became larger. This effect could not be explained by athletes' forecasted emotions, but it could be explained by the emotions they actually felt following the race. The more experience athletes had with athletics, the less they felt negative emotions after unsuccessful goal attainment. These findings are discussed in relation to possible underlying emotion regulation processes.
