Hierarchical modeling of paired comparison data

The method of paired comparisons belongs to a small group of techniques that provide explicit information about the consistency of individual and aggregated choices. This article investigates the link between the individual- and group-level judgments by extending R. D. Luce's (1959) model, which was originally developed for individual choice behavior, to a mixed-effects paired comparison model. It is shown that standard multilevel software for binary data can be used to estimate the model. The interpretation of the paired comparison parameters and statistical model tests are discussed in detail. An extensive analysis of an experimental study illustrates the usefulness of a hierarchical approach in modeling multiple pairwise judgments.     

The role of attribution of motivation in producing postsuppressional rebound

Three studies demonstrated that postsuppressional rebound (PSR) may be both reduced and enhanced by manipulating people's attributions about why they experience difficulty during suppression. Telling participants that suppression failures indicate a high motivation to use the suppressed construct produced more PSR than telling them that suppression failures indicate a low motivation to use the construct (Study 1). Telling participants that an external stimulus would make suppression easy produced more PSR than telling them that it would make suppression difficult (Study 2). Telling participants that suppressing a stereotype is difficult and unindicative of prejudice eliminated PSR (Study 3). These results support the notion that PSR occurs because people infer from the difficulty experienced during suppression and from suppression failures that they are motivated to use the suppressed construct.     

Set-Theoretic Absoluteness and the Revision Theory of Truth

We describe the solution of the Limit Rule Problem of Revision Theory and discuss the philosophical consequences of the fact that the truth set of Revision Theory is a complete 1/2 set.     

Familial correlates of social anxiety in children and adolescents

Retrospective studies suggest a relationship between parental rearing practices and social phobia. The present study investigated whether socially anxious children perceive their current parental rearing as rejecting, overprotective, and lacking emotional warmth, and as emphasizing the importance of other's opinion, and de-emphasizing social initiatives and family sociability. Furthermore, we examined whether parents of socially anxious children report to rely on such rearing practices, and suffer themselves from social fears. A regression analysis as well as extreme group comparisons were applied. Little support was found for the presumed role of the assessed family rearing aspects in the development of social anxiety in children. Solely family sociability (children's and mothers' report) and children's perception of overprotection of the mother predicted social anxiety in the regression analysis. Given the influence of the mentioned rearing practices, social anxiety of the mother still significantly predicted social anxiety of the child. In the extreme group comparisons, differences in the expected direction were found between socially anxious and normal children on parental rejection, emotional warmth, and family sociability. However, the lack of differences between socially anxious and clinical control children suggests that these variables do not form a specific pathway to social fears.     

Body dissatisfaction and irrational beliefs

To test the hypothesis that the irrational evaluative beliefs, postulated by Rational-Emotive Behavior Therapy, are associated with body dissatisfaction, 94 women (21 diagnosed with an eating disorder, 38 with high body dissatisfaction but without an eating disorder, and 35 with low body dissatisfaction) completed the Survey of Personal Beliefs and the Eating Disorders Inventory. Analysis showed no significant difference in body dissatisfaction between the Eating Disordered and High Body Dissatisfaction subgroups. No significant correlations between body dissatisfaction and irrational beliefs were found for the Eating Disordered subgroup. For the High Body Dissatisfaction subgroup, significant but low correlations were found between scores on body dissatisfaction and irrational standards for self and others and with negative self-rating. In terms of irrational beliefs the Eating Disordered and High Body Dissatisfaction subgroups showed a significantly greater tendency towards Catastrophizing, Low Frustration Tolerance, and Negative self-rating, compared to the controls, without any significant difference between the former two groups. The Eating Disordered subgroup but not the High Body Dissatisfaction subgroup differed significantly from the controls in terms of more Self-directed demands.     

Die Selektion dimensionaler räumlicher Präpositionen: automatisch und nicht ressourcenadaptierend

The selection of dimensional spatial prepositions: automatic and not resource adaptive Summary. Speakers were required to generate dimensional spatial expressions in order to specify the position of a to-be-localized object (LO) relative to a reference object (RO). Placing LO in different positions around RO enabled us to establish the areas of application for the different German spatial terms. Canonical expressions (to the right of/ to the left of or above/ below) were only used if LO was placed horizontally or vertically aligned with RO. In all other directions combined expressions, e.g. 'rechts oben' (to the right and above) were used, which are common in German. These areas of application were of the same shape when subjects were under time pressure (Experiment 1). Additionally, a concurrent secondary task which was proven having high cognitive demands (Experiment 2) did not influence the area of application (Experiment 3). We conclude from these results that the selection of dimensional prepositions is automatic and that it is not resource adaptive. Zusammenfassung. SprecherInnen sollten ein zu lokalisierendes Objekt (LO) relativ zu einem Referenzpunkt (RO) sprachlich durch dimensionale räumliche Ausdrücke lokalisieren. LO wurde in unterschiedlichen Richtungen um RO platziert, sodass sich die Anwendbarkeitsräume für die verschiedenen räumlichen Ausdrücke im Deutschen bestimmen ließen. Die kanonischen Bezeichner (rechts von /links von oder über/unter) wurden praktisch nur bei direkt horizontaler oder vertikaler Lage von LO gewählt, in allen anderen Fällen wurden kombinierte Ausdrücke (z.B. rechts oben) benutzt. Diese Anwendbarkeitsräume änderten sich nicht, wenn die Personen unter Zeitdruck produzierten (Experiment 1). Eine gleichzeitig zu bearbeitende Nebenaufgabe, die das kognitive System stark belastet (Experiment 2), führte ebenfalls zu keiner Änderung der Anwendbarkeitsräume (Experiment 3). Wir schließen daraus, dass die Selektion der räumlichen Ausdrücke automatisch erfolgt und dass sie nicht ressourcenadaptierend ist.     

Cell-mediated immune hypersensitivity is stronger in the left side of the body than the right in healthy young subjects.

More frequent appearance of herpes zoster infection on the left side of the body has been noted. In women, breast cancer occurs more frequently on the left side. It has been suggested that the left neocortex is involved in neuroimmunomodulation via the dopaminergic system. In this study, our purpose was to investigate the possible difference in cell-mediated hypersensitivity between right and left body sides using the tuberculin test with 22 male and 36 female healthy high school students. In the present study, the cell-mediated hypersensitivity was higher in the left side of the body than the right. This difference was slightly more apparent in the girls and may be related to brain asymmetry in neuroimmunomodulation.     

What Predicts Adolescent Violence in Better-Off Neighborhoods?

Predictors of repeated violent delinquency across ages 13–19 were investigated in a longitudinal sample of 420 urban adolescent males living in high- compared to low-socioeconomic status (SES) neighborhoods. Adolescents in high-SES neighborhoods were significantly less likely than their counterparts in low-SES neighborhoods to engage in serious and violent delinquency. Results indicated that risk factors for later repeated violence among adolescents in high-SES neighborhoods, such as physical aggression, may be biologically based, whereas risk factors for later violence among adolescents in low-SES neighborhoods, such as poor parent–adolescent communication and early intercourse, appeared to be context-dependent. Having positive attitudes toward problem behavior and delinquent peers increased risk for later violence regardless of neighborhood SES type. Theoretical and practical implications of the findings are discussed.     

Responsiveness to Threat and Incentive in Bipolar Disorder: Relations of the BIS/BAS Scales with Symptoms

Over the past 10 years, theorists have suggested that bipolar disorder symptoms result from increases and decreases in the activity of the Behavioral Activation or Facilitation System (BAS or BFS) and the Behavioral Inhibition System (BIS). These neurobehavioral systems are thought to determine the intensity of affective and behavioral responses to incentives and threats. This study examined cross-sectional and prospective associations of self-reported BIS and BAS with mania and depression in a sample of 59 individuals diagnosed with Bipolar I disorder. Depression was tied to BIS, pointing to the importance of sensitivity to threats in depression. However, links between BIS and depression appeared state-dependent. BAS subscales did not correlate with manic symptoms in a state-dependent manner; however, BAS (total scale and reward responsiveness subscale) predicted relative intensification of manic symptoms over time. Thus, evidence suggests that BAS sensitivity may constitute a vulnerability to mania among persons diagnosed with bipolar disorder. Discussion focuses on the integrative potential of the BIS/BAS constructs for linking psychosocial and biological research on bipolar disorder.
