Portrayal of personality in Victorian novels reflects modern research findings but amplifies the significance of agreeableness

All literature embodies an implicit theory of personality and human nature (Hogan, 1976). The research described here investigates the implicit personality theory embedded in the behavior of 435 characters in 143 canonical Victorian novels. Characters were rated on the Web by 519 scholars and students of 19th-century British literature. Ratings included the characters’ goals, success in achieving goals, mate preferences and strategies, and personality according to the Five Factor Model. Results suggest that novels by Victorian authors largely reflect personality and human nature as understood by modern personality psychology, but Victorian authors amplify the significance of agreeableness and thus, whether intentionally or not, encourage cooperative impulses in readers.     

By the numbers: Structure-seeking individuals prefer quantitative over qualitative representations of personal value to compensate for the threat of unclear performance contingencies

What combination of dispositional and situational factors leads people to represent their personal value in quantitative terms (e.g., salary) rather than qualitative terms (e.g., virtue)? Integrating research on quantitative information seeking, dispositional epistemic motivation, and learned helplessness, the current article hypothesized that individuals high, but not low, in uncertainty avoidance (measured with the Personal Need for Structure Scale [PNS]) would prefer quantitative (over qualitative) value representations to compensate for the diminished self-esteem certainty caused by exposure to unclear performance contingencies. Accordingly, in Study 1 high-PNS participants exposed to unclear (vs. clear) performance contingencies in one domain (visual intelligence) preferred a quantitative value representation in another domain (verbal intelligence). Study 2 showed that this effect is mediated by self-esteem certainty, not self-esteem level. Study 3 included a failure feedback condition to further isolate the role of epistemic motivation, as distinct from self-enhancement motivation, in driving the tendency to quantify personal value.     

Diagnosing fatigue in gait patterns by support vector machines and self-organizing maps

The aim of the study was to train and test support vector machines (SVM) and self-organizing maps (SOM) to correctly classify gait patterns before, during and after complete leg exhaustion by isokinetic leg exercises. Ground reaction forces were derived for 18 gait cycles on 9 adult participants. Immediately before the trials 7–12, participants were required to completely exhaust their calves with the aid of additional weights (44.4 ± 8.8 kg). Data were analyzed using: (a) the time courses directly and (b) only the deviations from each individual’s calculated average gait pattern. On an inter-individual level the person recognition of the gait patterns was 100% realizable. Fatigue recognition was also highly probable at 98.1%. Additionally, applied SOMs allowed an alternative visualization of the development of fatigue in the gait patterns over the progressive fatiguing exercise regimen.     

Kommentare zu ?Ambivalenz weiterschreiben��

The authors comment on the results of the Zürich symposium with varied weighting. Ambivalence is brought into relation with a hypothetical genesis of human thinking and understood as a reflection of the fundamental dialogical structure, which owes itself to an exchange of symbolic messages. A further consideration describes that the ??valley of the uncanny??, whose connection to death Lilly Gast has shown, could also have a fundamental connection with sexuality bared of all bonds, which releases the same fears as death. A difficulty would lie in the inflationary use of the term: every ambiguousness or diversity would sometimes generally be subsumed under ambivalence and therefore all selectivity would become lost. Also discussed is the ambivalence of the term, or the question, whether the term has not lost significance. Finally its relevance in pediatric and adolescent-specific perspectives will be examined.     

Cost-Benefit Analysis Mediation of the Relationship Between Sensation Seeking and Risk Behavior

Risk behavior during adolescence results in substantial morbidity and mortality. Sensation seeking consistently relates to engagement in risk behavior, but the psychological mediators of this relationship remain unclear. The current study demonstrates that adolescents’ judgments of the costs versus benefits of risk behavior were a significant mediator of this relationship. Participants were 406 racially and ethnically diverse adolescents ages 12-17 (M = 14.5, SD = 1.7; 48.3% female) who participated in a larger multi-site investigation of personality and neurocognitive predictors of risk behavior. Data were collected via self-report in a single laboratory session. Mediation of the relationship of sensation seeking to risk behavior was tested using structural equation modeling. Results indicated that higher levels of sensation seeking predicted weighing the benefits of risk behavior higher than its costs, which in turn predicted higher levels of risk behavior. Implications of these findings for understanding mechanisms underlying adolescents’ risk behavior and directions for future research are discussed.     

On Not Changing the Problem: A Reply to Howson

Howson's critique of my essay on Hume's problem of induction levels two main charges. First, Howson claims that I have attributed to him an error that he never made, and in fact which he warned against in the very text that I cite. Secondly, Howson argues that my proposed solution to Hume's problem is flawed on technical and philosophical grounds. In response to the first charge, I explain how Howson's text justifies attributing to him the claim that the principle of induction is shown to be inconsistent by Goodman's riddle. In regards to the second, I show that Howson's objections rest on misunderstandings of formal learning theory and on conflating the problem of induction with the problem of unconceived alternatives.     

Factor structure and reliability of the Spanish adaptation of the Children's Yale-Brown Obsessive-Compulsive Scale--Self Report (CY-BOCS-SR)

The aim of this study was the adaptation to Spanish of the ?Children's Yale-Brown Obsessive-Compulsive Scale--Self Report? (CY-BOCS-SR), one of the most frequently utilized scales in the assessment of obsessive-compulsive behaviors. After its translation to Spanish, its factor invariance in boys and girls, reliability, and relationship with the children's age were examined. Lastly, normative data for this Spanish version are presented. The sample comprised 1,706 children and adolescents from the general population. Results show that the factor composition of the CY-BOCS-SR does not present a very good fit to the usual scoring of three scales were observed: Obsession Severity, Compulsion Severity, and total score. Results also show that the factor validity and reliability of the CY-BOCS-SR improve remarkably if items related to Resistance to Obsessions and Compulsions are considered a different factor from Severity. It is concluded that the Spanish version of the CY-BOCS-SR has similar psychometric characteristics as the original English version.     

Does d-Cycloserine Augmentation of CBT Improve Therapeutic Homework Compliance for Pediatric Obsessive–Compulsive Disorder?

Clinical studies in adults and children with obsessive–compulsive disorder (OCD) have shown that d-cycloserine (DCS) can improve treatment response by enhancing fear extinction learning during exposure-based psychotherapy. Some have hypothesized that improved treatment response is a function of increased compliance and engagement in therapeutic homework tasks, a core component of behavioral treatment. The present study examined the relationship between DCS augmented cognitive-behavioral therapy (CBT) and homework compliance in a double-blind, placebo controlled trial with 30 youth with OCD. All children received 10 CBT sessions, the last seven of which included exposure and response prevention paired with DCS or placebo dosed 1 h before the session started. Results suggested that DCS augmented CBT did not predict improved homework compliance over the course of treatment, relative to the placebo augmented CBT group. However, when groups were collapsed, homework compliance was directly associated with treatment outcome. These findings suggest that while DCS may not increase homework compliance over time, more generally, homework compliance is an integral part of pediatric OCD treatment outcome.
