Validity and Application of Computer-simulated Scenarios in Personnel Assessment

In Germany computer-simulated scenarios have been applied in personnel management for several years. Their goals are either to assess how potential managers cope with complex and connected problem states (job aptitude testing aspect) or to provide feedback on manager strengths and weaknesses in dealing with complexity, and how to modify these when necessary (training aspect). This paper presents and evaluates those scenarios that have been subjected to validity studies.     

Before and After the German Reunification: Changes in Observers' Commentaries on Achievements in a Natural Experiment1

East Germany (EG) and West Germany (WG) had been divided by the inner-German frontier for more than 4 decades. In 1989, the frontier fell, and in 1990, East and West Germany were reunified. To study differences in attributional patterns as a consequence of this political change, the attributions of WG TV-sport commentators during the 1988 and 1992 Olympic Games were analyzed for their frequency and antecedents. Results show an increase in internal and stable attributions after success in contrast to failure attributions; the former to a greater extent in 1992. In 1988 and in 1992, the positive achievements of EG athletes were attributed more often to internal causes than were the positive achievements of WG athletes. In 1992, attributions for EG athletes were more likely to be stable than in 1988.     

Cognitive and affective experiences of minority and majority members: The role of group size, status, and power

Four studies examined cognitive and affective experiences of minority and majority members. We predicted and found that minority members were more cognitively preoccupied with their group membership and experienced less positive affect as a consequence of their group membership than majority members. The first experiment established these effects with numerical minority and majority groups. The second experiment ruled out status as an explanatory variable, and the third experiment uncovered the role of power in the differential cognitive and affective experiences of minority and majority members. The final field study substantiated the ecological robustness of the experimental findings and provided further evidence for the role of power. The interrelation of status and power is discussed as well as the phenomenology of being a minority member.     

On the determination of autistoid organizations in non-autistic adults

Psychogenic autistic phenomena occurring in non-autistic adults are being increasingly discussed in the psychoanalytical literature. The author endeavours to determine autistoid organizations, which are understood to be a particular form of pathological retreat. Together with the use of autistic objects, two-dimensional levelling out, the failure of unconscious communication, and of projective identification, a characteristic of these retreats is that they are meant to afford protection against paranoid-schizoid fears of the external and unintegrated states of the internal world. The formation of such autistic reactions should be sought not only in traumatic separations and the inadequate containment of primary objects, but also in constitutional weakening. Intolerance accompanying projective identification and damage to primal fantasies/preconceptions are discussed. In conclusion, a clinical illustration with autistoid and hypochondriacal retreats clarifies some of the aspects discussed.     

Kosteneffektivität ambulanter Psychotherapie

Background

There is a lack of cost-effectiveness analyses (CEA) of psychotherapeutic treatments.

Material and methods

Cost-effectiveness analysis was applied to a sub-sample of 122 psychotherapy outpatients who participated in a large longitudinal study on outpatient psychotherapy (TRANS-OP study). Participants received either psychodynamic psychotherapy (PD, n=69) or cognitive behavioral therapy (CBT, n=53). Effectiveness (change in symptomatic impairment over 2 years) was assessed via the German version of the Outcome Questionnaire (OQ-45.2). Direct health care costs during a 2-year period (psychotherapy and other health care utilizations) were obtained from health insurance claims. Cost-effectiveness analysis methods included incremental cost-effectiveness ratios (ICER) and the net benefit regression approach.

Results

Cost-effectiveness analyses showed no significant differences between the two treatments, neither head-to-head, nor with regard to advantages in certain subgroups of psychotherapy outpatients. A slight dominance of CBT in costs was not maintained after controlling for covariates.

Conclusion

Provided that pivotal covariates such as treatment need are taken into account, cost-effectiveness analyses can contribute to a more equitable distribution of psychotherapeutic resources.     

Bidimensional regression: assessing the configural similarity and accuracy of cognitive maps and other two-dimensional data sets

Bidimensional regression is a method for comparing the degree of resemblance between 2 planar configurations of points and, more generally, for assessing the nature of the geometry (Euclidean and non-Euclidean) between 2-dimensional independent and dependent variables. For example, it can assess the similarity between location estimates from different tasks or participant groups, measure the fidelity between cognitive maps and actual locations, and provide parameters for psychological process models. The authors detail the formal similarity between uni- and bidimensional regression, provide computational methods and a new index of spatial distortion, outline the advantages of bidimensional regression over other techniques, and provide guidelines for its use. The authors conclude by describing substantive areas in psychology for which the method would be appropriate and uniquely illuminating.     

Evidence of separable spatial representations in a virtual navigation task

Three experiments investigated spatial orientation in a virtual navigation task. Subjects had to adjust a homing vector indicating their end position relative to the origin of the path. It was demonstrated that sparse visual flow was sufficient for accurate path integration. Moreover, subjects were found to prefer a distinct egocentric or allocentric reference frame to solve the task. "Turners" reacted as if they had taken on the new orientation during turns of the path by mentally rotating their sagittal axis (egocentric frame). "Nonturners," by contrast, tracked the new orientation without adopting it (allocentric frame). When instructed to use their nonpreferred reference frame, both groups displayed no decline in response accuracy relative to their preferred frame; even when presented with reaction formats based on either ego or allocentric coordinates, with format unpredictable on a trial, both groups responded highly accurately. These findings support the assumption of coexisting spatial representations during navigation.
