Coaching

Coaching ist in Wirtschaftsunternehmen weit verbreitet. Angesichts der stetig steigenden Ver?nderungsgeschwindigkeit der Arbeits- und pers?nlichen Lebenswelten suchten zun?chst Führungskr?fte professionelle Coaches, die ihnen als vertraute Gespr?chspartner zur Seite standen. Coachingma?nahmen werden aber auch zunehmend von Politikern, Medienvertretern, Künstlern und Freiberuflern nachgefragt.

Isomorphism and Equational Equivalence of Continuous λ-Models

We will present several results on two types of continuous models of -calculus, namely graph models and extensional models. By introducing a variant of Engeler's model construction, we are able to generalize the results of [7] and to give invariants that determine a large family of graph models up to applicative isomorphism. This covers all graph models considered in the litterature so far. We indicate briefly how these invariants may be modified in order to determine extensional models as well.Furthermore, we use our construction to exhibit graph models that are not equationally equivalent. We indicate once again how the construction passes on to extensional models.     

Influence of win-loss ratio on performance,satisfaction and preference for opponents

Hypotheses about the preference for opponents in competitive situations, about performance under various win-loss ratios, and about task and opponent satisfaction under various win-loss ratios were tested. A 5 × 5 latin square with four replications and a repeated measure factor of trials was the design used with 20 female college students as subjects. The five different win percents were W₁₀, W₃₀, W₅₀, W₇₀, and W₉₀. A manipulative maze task was used with subjects receiving 20 trials against each of five confederate opponents. Results indicated that (a) when a person knows little or nothing about her ability level she initially prefers to compete with opponents of low ability but with each subsequent contest opponents of higher ability levels are preferred; (b) subjects performed better in the W₅₀ condition; (c) task satisfaction is higher when the percent of wins is equal to or greater than the percent of losses; and (d) opponent satisfaction is greater for opponents who perform equal to or better than the subject.     

The use of modeling to increase independent behavior

Three experiments were conducted aimed at increasing independence via use of modeling procedures in, respectively, two samples of neurotic outpatients and a sample of psychiatric inpatients. Significant gains in independence emerged in all three investigations. Subsidiary findings are reported regarding the operation in clinical contexts of ‘modeling-enhancers’ of demonstrated effectiveness in laboratory settings.     

Optimal designs for the generalized partial credit model

Analysing ordinal data is becoming increasingly important in psychology, especially in the context of item response theory. The generalized partial credit model (GPCM) is probably the most widely used ordinal model and has found application in many large-scale educational assessment studies such as PISA. In the present paper, optimal test designs are investigated for estimating persons’ abilities with the GPCM for calibrated tests when item parameters are known from previous studies. We find that local optimality may be achieved by assigning non-zero probability only to the first and last categories independently of a person's ability. That is, when using such a design, the GPCM reduces to the dichotomous two-parameter logistic (2PL) model. Since locally optimal designs require the true ability to be known, we consider alternative Bayesian design criteria using weight distributions over the ability parameter space. For symmetric weight distributions, we derive necessary conditions for the optimal one-point design of two response categories to be Bayes optimal. Furthermore, we discuss examples of common symmetric weight distributions and investigate under what circumstances the necessary conditions are also sufficient. Since the 2PL model is a special case of the GPCM, all of these results hold for the 2PL model as well.     

Resilients,Overcontrollers, and Undercontrollers: The replicability of the three personality prototypes across informants

The study of patterns in personality structure reveals three replicable prototypes: Resilients, Overcontrollers, and Undercontrollers. The three prototypes were first identified in children using ratings based on the California Child Q‐set (see Block, 1971). Only recently, the three prototypes were replicated in self‐reports on questionnaires intended to assess the Big Five (see e.g. Asendorpf, Borkenau, Ostendorf, & van Aken, 2001). This paper addresses the question of whether the three prototypes are replicable across different data sources. Cluster structures in self‐, peer, and behaviour ratings, all based on the Big Five, were examined in a sample of 600 monozygotic and dizygotic twins ranging in age from 18 to 70 years. The three prototypes could be clearly identified in the self‐reports only, whereas in ratings by others only the Resilient prototype could be replicated. In both peer and behaviour ratings, the second and the third cluster reflected a Non‐desirable and an Average type. The analysis of cross‐data consistency revealed only moderate agreement in assignments of individual subjects to types. The findings suggest that personality types depend strongly on personality measures and informants. Copyright © 2003 John Wiley & Sons, Ltd.     

Facing Europe: visualizing spontaneous in-group projection

Individuals perceive their own group to be more typical of a shared superordinate identity than other groups are. This in-group projection process has been demonstrated with both self-report and indirect measures. The two studies reported here extend this research to the visual level, specifically, within the domain of faces. Using an innovative reverse-correlation approach, we found that German and Portuguese participants' visual representations of European faces resembled the appearance typical for their own national identity. This effect was found even among participants who explicitly denied that one nation was more typical of Europe than the other (Study 1). Moreover, Study 2 provides experimental evidence that in-group projection is restricted to inclusive superordinate groups, as the effect was not observed for visual representations of a category ("Australian") that did not include participants' in-group. Implications for the in-group projection model, as well as for the applicability of reverse-correlation paradigms, are discussed.
