Einige (neuere) Bemerkungen zur freien Assoziation

Three aspects of free association, namely the technical aspect, the aspect of content and the processual aspect, are examined in terms of the ideological development of this concept, which is still central for psychoanalysis. Further, it is shown that the theoretical conception of free association and of its claim and scope as well as the communication of the fundamental rule have changed in the course of time. New studies in basic research could lead to a reassessment of free association.     

Skulking around the dinosaur: Eliciting cues to children's deception via strategic disclosure of evidence

Research has shown that cues to deception are more salient as an effect of strategic use of evidence (SUE) during interviews. This study examined the feasibility of the SUE‐technique for eliciting cues to children's deception. Experiment 1 investigated verbal cues to deception as a function of early vs. late disclosure of evidence. Eighty‐four children (12–14 years) either guilty or innocent of a mock crime were interviewed. As predicted, deceptive statements were significantly more inconsistent with the evidence than truthful statements, and this was more pronounced as a function of late compared to early disclosure of evidence. In Experiment 2, adult observers (N = 168) made veracity assessments of the videotaped statements. Observers in the late disclosure condition achieved an accuracy rate higher than chance (63.1%), whereas accuracy rates in the early disclosure condition were at chance level (56%). Accuracy rates were significantly higher for truthful (70.2%), than deceptive statements (48.8%). Copyright © 2009 John Wiley & Sons, Ltd.     

A new measure for dispositional optimism and pessimism in young children

We describe here a new test for dispositional optimism and pessimism in young children, the Parent‐rated Life Orientation Test of children (the PLOT) and assess its psychometric properties. Two hundred and twenty one mother–father pairs rated their children's (mean age = 8.1, SD = 0.3 years) dispositional optimism and pessimism using a new scale, the PLOT, including four optimism and four pessimism items. We associated the PLOT with parent‐rated self‐esteem (Behavioral Rating Scale of Presented Self‐Esteem in Young Children), social competence (Social Competence and Behaviour Evaluation Scale, the SCBE‐30), psychiatric symptoms (Child Behaviour Checklist, the CBCL) and temperament (Children's Behaviour Questionnaire, the CBQ) of the child. A confirmatory factor analysis (CFA) of the mother‐ and father‐rated PLOT revealed a significantly better fit for a two‐ over a one‐factor solution (p < 0.001). The optimism and pessimism subscales displayed good reliabilities, inter‐parental agreement and modest to moderate associations, in the expected direction, with the measures of self‐esteem, social competence, temperament and behaviour problems. To conclude, the PLOT shows good construct and convergent validity and reliability. The findings encourage its use to assess early emerging generalized expectancies of positive and negative outcomes in young children. Copyright © 2009 John Wiley & Sons, Ltd.     

Evidenzbasierte Psychotherapie der Depression

Depressive disorders are among the most frequent reasons for utilizing the health care system. Despite the availability of efficacious treatments and further advances throughout the last years, there is still a need for improving diagnostic and therapeutic procedures. A promising approach is the implementation of evidence- and consensus-based guidelines. The German “Nationale VersorgungsLeitlinie Unipolare Depression” are evidence- and consensus-based clinical practise guidelines for patients with unipolar depression. All relevant stakeholders have been involved in its development and have passed the final version at the end of 2009 to foster compliance throughout. The available evidence allows the derivation of differentiated treatment recommendations, also with regard to concomitant antidepressant medication or as alternative treatment options. In acute therapy watchful waiting over 14 days is recommended for mild depression and psychotherapy after persistence of symptoms. In cases of moderate depression, psychotherapy and pharmacotherapy are equally recommended, in cases of severe depression a combination of both is recommended.     

Response priming driven by local contrast, not subjective brightness

We demonstrate qualitative dissociations of brightness processing in visuomotor priming and conscious vision. Speeded keypress responses to the brighter of two luminance targets were performed in the presence of preceding dark and bright primes (clearly visible and flanking the targets) whose apparent brightness values were enhanced or attenuated by a visual illusion. Response times to the targets were greatly affected by consistent versus inconsistent arrangements of the primes, relative to the targets (response priming). Priming effects could systematically contradict subjective brightness matches, such that one prime could appear brighter than the other but could prime as if it were darker. Systematic variation of the illusion showed that response-priming effects depended only on local flanker-background contrast, not on the subjective appearance of the flankers. Our findings suggest that speeded motor responses, as opposed to conscious perceptual judgments, access an early phase of lightness and brightness processing prior to full lightness constancy.     

Continuity of father-rated temperament from infancy to middle childhood

Continuity of father-rated temperament in Finnish children (n = 115) aged from 6 months (the IBQ) to 5.5 years (the CBQ) was explored within the theoretical framework developed by Rothbart. Father-rated activity level, smiling and laughter and distress to limitations showed significant differential homotypic and heterotypic continuity, while soothability, duration of orienting and fear showed significant differential heterotypic continuity. On the level of latent superconstructs, father-rated positive and negative infant affectivity accounted for 5.1, 22.7 and 10.0% of the variance in childhood extraversion, effortful control and negative affectivity, respectively. Inter-parental comparisons (n = 109 family units) revealed that father-rated continuity was similar to mother-rated continuity. These findings give empirical credence to Rothbart's theory and to father-rated temperamental continuity from infancy onwards.     

The earliest electrophysiological correlate of visual awareness?

To examine the neural correlates and timing of human visual awareness, we recorded event-related potentials (ERPs) in two experiments while the observers were detecting a grey dot that was presented near subjective threshold. ERPs were averaged for conscious detections of the stimulus (hits) and nondetections (misses) separately. Our results revealed that hits, as compared to misses, showed a negativity around 180-350 ms at occipital and posterior temporal sites. It was followed by a positive wave after 400-500 ms, peaking at parietal sites. These correlates were not affected by a manipulation of attention. The early negativity, called 'visual awareness negativity' (VAN), may be a general, primary electrophysiological correlate of visual awareness. The present data show that it can be observed in response to appearance of a stimulus in visual awareness and that it generalizes across different manipulations of stimulus visibility.
