Inventar zur therapeutischen Beziehung (ITB)

A successful psychotherapy requires a good therapeutic relationship. An adequate operationalization by German diagnostic instruments has to be improved. A new instrument for measuring the therapeutic relationship from the patient’s perspective is presented. It is suitable for various therapeutic orientations, integrates current empirical findings in a broad theoretical framework and corrects methodological deficits of the existing German questionnaires. The therapeutic relationship questionnaire (ITB) was developed with a sample of 44 therapists and 519 inpatient, outpatient and day clinic patients. The ITB findings confirm a very good reliability (internal consistency and retesting reliability). There is initial evidence for convergent, divergent and differential validity and for associations with therapy effects. The ITB is an economic instrument that in contrast to other questionnaires measures a general factor which could be replicated in several confirmatory and exploratory factor analyses.     

Configurations of unemployment,reemployment, and psychological well-being: A longitudinal study of unemployed individuals in Portugal

This study examined how four different configurations of unemployment and reemployment (defined by history of past unemployment and unemployment/reemployment 3 years later) related to changes in psychological well-being. The longitudinal sample consisted of 566 Portuguese men and women who were unemployed at the beginning of the study. Using true change score models, we found that individuals who reported a long period of unemployment at T1 but were reemployed at T2 showed meaningful gains in positive affect and life satisfaction compared to those who had a shorter history of unemployment and were reemployed. An examination of gender differences revealed that the women who were reemployed after a long history of unemployment showed the greatest relative gains in positive affect. We conclude by noting limitations of this research and suggesting future research to address these limitations.     

Recurrence plot analyses suggest a novel reference system involved in newborn spontaneous movements

The movements of newborns have been thoroughly studied in terms of reflexes, muscle synergies, leg coordination, and target-directed arm/hand movements. Since these approaches have concentrated mainly on separate accomplishments, there has remained a clear need for more integrated investigations. Here, we report an inquiry in which we explicitly concentrated on taking such a perspective and, additionally, were guided by the methodological concept of home base behavior, which Ilan Golani developed for studies of exploratory behavior in animals. Methods from nonlinear dynamics, such as symbolic dynamics and recurrence plot analyses of kinematic data received from audiovisual newborn recordings, yielded new insights into the spatial and temporal organization of limb movements. In the framework of home base behavior, our approach uncovered a novel reference system of spontaneous newborn movements.     

End-state comfort in bimanual object manipulation

The present experiment investigated the sensitivity for end-state comfort in a bimanual object manipulation task. Participants were required to simultaneously reach for two bars and to place the objects' ends into two targets on the table. The design of the experiment allowed to dissociate the relative roles of initial means (e.g., the selection of grips) and final postures (e.g., the anticipation of end-states). The question of interest was whether affording different grip patterns for the two hands would introduce a bias away from reaching end-state comfort. Results revealed a strong sensitivity for end-state comfort, independent of the required grip patterns. In particular, end-state comfort was preferred even if this meant selecting different initial means (i.e., different grips) for the two hands. Hence, end-state oriented action planning appears to dominate interaction costs that may result from motor-related, intermanual interference. We infer that movement planning is constrained by action goals (e.g., a comfortable end-posture for both hands), but largely unaffected by the type of motor actions necessary to achieve these goals.     

Sex-specific differences in olfactory sensitivity for putative human pheromones in nonhuman primates

In humans, the volatile C19-steroids androsta-4,16-dien-3-one (AND) and estra-1,3,5(10),16-tetraen-3-ol (EST) have been shown to modulate autonomic nervous system responses, and to cause hypothalamic activation in a gender-specific manner. Using two conditioning paradigms, the authors here show that pigtail macaques and squirrel monkeys of both sexes were able to detect AND and EST at concentrations in the micromolar and mM range, respectively. Male and female spider monkeys, in contrast, differed markedly in their sensitivity to these two odorous steroids, with males not showing any behavioral responses to the highest concentrations of AND tested and females not responding to the highest concentrations of EST. These data provide the first examples of sex-specific bimodal distributions of olfactory sensitivity in a nonhuman primate species.
