Incarcerated Violent Offenders' Ability to Avoid Revealing Their Potential for Violence on the Rorschach and the MMPI–2

Recently, Hartmann and Hartmann (2014) Hartmann, E., &; Hartmann, T. (2014): The impact of exposure to Internet-based information about the Rorschach and the MMPI–2 on psychiatric outpatients' ability to simulate mentally healthy test performance, Journal of Personality Assessment, 96, 432–444. doi:10.1080/00223891.2014.882342.[Taylor &; Francis Online], [Web of Science ®] , [Google Scholar] found that psychiatric outpatients, both with and without access to Internet-based information about the Rorschach Inkblot Method (RIM; Weiner, 2003 Weiner, I. B. (2003). Principles of Rorschach interpretations (2nd ed.). Mahwah, NJ: Erlbaum. [Google Scholar]) and the MMPI–2 (Butcher, Dahlstrom, Graham, Tellegen, &; Kaemmer, 1989 Butcher, J. N., Dahlstrom, W. G., Graham, J. R., Tellegen, A., &; Kaemmer, B. (1989). Manual for the Restandardized Minnesota Multiphasic Personality Inventory: MMPI–2. An administration and interpretive guide. Minneapolis: University of Minnesota Press. [Google Scholar]), were unable to imitate healthy test performance on these tests. We replicated the study by administering the RIM and the MMPI–2 to 63 incarcerated violent offenders using similar testing conditions. As in the previous study, comparisons were made not only among the 3 subgroups of incarcerated offenders, but also between these offender groups and the group of nonpatients examined in the previous study. On the RIM, Internet-coached and uncoached “faking good” offenders produced records with significantly higher F% and X–% and significantly lower M, m, SumC, X+%, P, AG, and COP than nonoffenders under standard instructions (effect sizes between d = 0.24 and d = 2.39). For AgC, AgPot, AgPast, and TCI% there were no significant differences between the faking offenders and the nonoffenders under standard instructions. On the MMPI–2 clinical scales, there were no significant differences between the faking good groups and the nonoffenders under standard instructions, except on Hs, Pd, and Sc. Both faking groups were identifiable by their high L scale scores. Although both faking groups managed to avoid giving responses with aggressive and generally psychopathological content on the RIM, they were unable to produce test profiles demonstrating healthy test performance on any of the tests; nevertheless, Internet-based test information might weaken test validity.     

Stabilizing and Changing Phenomenal Worlds: Ludwik Fleck and Thomas Kuhn on Scientific Literature

In the work of both Ludwik Fleck and Thomas Kuhn the scientific literature plays important roles for stability and change of scientific phenomenal worlds. In this article we shall introduce the analyses of scientific literature provided by Fleck and Kuhn, respectively. From this background we shall discuss the problem of how divergent thinking can emerge in a dogmatic atmosphere. We shall argue that in their accounts of the factors inducing changes of scientific phenomenal worlds Fleck and Kuhn offer substantially different approaches, and we shall discuss in which respects their approaches may be compatible.

Do targets of workplace bullying portray a general victim personality profile?

The aim of this study is to examine differences in personality between a group of bullied victims and a non-bullied group. The 144 participants, comprising of 72 victims and a matched contrast group of 72 respondents, completed Goldberg's (1999) International Personality Item Pool (IPIP). Significant differences emerged between victims and non-victims on four out of five personality dimensions. Victims tended to be more neurotic and less agreeable, conscientious and extravert than non-victims. However, a cluster analysis revealed that the victim sample can be divided into two personality groups. One cluster, which comprised 64% of the victim sample, do not differ from non-victims as far as personality is concerned. Hence, the results indicate that there is no such thing as a general victim personality profile. However, a small cluster of victims tended to be less extrovert, less agreeable, less conscientious, and less open to experience but more emotional unstable than victims in the major cluster and the control group. Further, both clusters of victims scored higher than non-victims on emotional instability, indicating that personality should not be neglected as being a factor in understanding the bullying phenomenon.     

The asymptotic bias of minimum trace factor analysis, with applications to the greatest lower bound to reliability

In theory, the greatest lower bound (g.l.b.) to reliability is the best possible lower bound to the reliability based on single test administration. Yet the practical use of the g.l.b. has been severely hindered by sampling bias problems. It is well known that the g.l.b. based on small samples (even a sample of one thousand subjects is not generally enough) may severely overestimate the population value, and statistical treatment of the bias has been badly missing. The only results obtained so far are concerned with the asymptotic variance of the g.l.b. and of its numerator (the maximum possible error variance of a test), based on first order derivatives and the asumption of multivariate normality. The present paper extends these results by offering explicit expressions for the second order derivatives. This yields a closed form expression for the asymptotic bias of both the g.l.b. and its numerator, under the assumptions that the rank of the reduced covariance matrix is at or above the Ledermann bound, and that the nonnegativity constraints on the diagonal elements of the matrix of unique variances are inactive. It is also shown that, when the reduced rank is at its highest possible value (i.e., the number of variables minus one), the numerator of the g.l.b. is asymptotically unbiased, and the asymptotic bias of the g.l.b. is negative. The latter results are contrary to common belief, but apply only to cases where the number of variables is small. The asymptotic results are illustrated by numerical examples.This research was supported by grant DMI-9713878 from the National Science Foundation.     

Predicting proactive behaviour at work: Exploring the role of personality as an antecedent of whistleblowing behaviour

This paper reports on the role of personality as an antecedent of proactive behaviour at work in the form of whistleblowing. In the interest of triangulation, two studies were used, along with two personality measures. The results of Study 1, conducted among 503 municipality employees, show that the NEO Five‐Factor Inventory dimensions of extraversion and agreeableness are significantly associated with whistleblowing, with odds ratios of 1.13 and 0.91, respectively. The result from Study 2, conducted among a representative sample of employees, shows that the circumplex of interpersonal problems dimension domineering was significantly associated with whistleblowing, with an odds ratio of 1.66. The results suggest that personality, in the form of high extraversion and dominance and low agreeableness, do play a role as antecedents of whistleblowing.

Body satisfaction during pregnancy

The current study examines how body satisfaction of pregnant women compares to that of nonpregnant women. The sample included 68 pregnant and 927 nonpregnant young women who participated in a population-based longitudinal study examining eating and weight concerns in young adults. Body satisfaction was assessed using a 10-item modified version of the Body Shape Satisfaction Scale. The longitudinal design allowed for the assessment of body satisfaction among women both prior to and during their pregnancy. Mean body satisfaction was higher in pregnant women (32.6, 95% CI: 30.7-34.5) than nonpregnant women (29.6, 95% CI: 29.1-30.1) with moderate effect size 0.32, after adjusting for body satisfaction and body mass index prior to pregnancy, indicating that pregnant women experienced a significant increase in body satisfaction from the time prior to their pregnancy (p=.003) despite weight gain. These findings have important implications for clinicians delivering weight-related messages to women during pregnancy.     

Increased activation in superior temporal gyri as a function of increment in phonetic features

A common assumption is that phonetic sounds initiate unique processing in the superior temporal gyri and sulci (STG/STS). The anatomical areas subserving these processes are also implicated in the processing of non-phonetic stimuli such as music instrument sounds. The differential processing of phonetic and non-phonetic sounds was investigated in this study by applying a “sound-morphing” paradigm, where the presence of phonetic features were parametrically varied, creating a step-wise transition from a non-phonetic sound into a phonetic sound. The stimuli were presented in an event-related fMRI design. The fMRI-BOLD data were analysed using parametric contrasts. The results showed a higher sensitivity for sounds containing phonetic features compared to non-phonetic sounds in the middle part of STG, and in the anterior part of the planum temporale (PT) bilaterally. Although the same areas were involved in the processing of non-phonetic sounds, a difference in activation was evident in the STG, with an increase in activation related to increment of phonetic features in the sounds. The results indicate a stimulus-driven, bottom-up process that utilizes general auditory resources in the secondary auditory cortex, depending on specific phonetic features in the sounds.     

Global optimality of the successive Maxbet algorithm

The Maxbet method is an alternative to the method of generalized canonical correlation analysis and of Procrustes analysis. Contrary to these methods, it does not maximize the inner products (covariances) between linear composites, but also takes their sums of squares (variances) into account. It is well-known that the Maxbet algorithm, which has been proven to converge monotonically, may converge to local maxima. The present paper discusses an eigenvalue criterion which is sufficient, but not necessary for global optimality. However, in two special cases, the eigenvalue criterion is shown to be necessary and sufficient for global optimality. The first case is when there are only two data sets involved; the second case is when the inner products between all variables involved are positive, regardless of the number of data sets.The authors are obliged to Henk Kiers for critical comments on a previous draft.
