How goal-fulfillment decreases aggression

We suggest that the goal to aggress increases accessibility of aggressive thoughts, and that after goal-fulfillment, accessibility of aggressive content is reduced. Experiment 1 showed an increase in accessibility of aggression after imagining an aggression-eliciting situation compared to non-aggressive content. After goal-fulfillment the accessibility of aggression was reduced, regardless of whether fulfillment was achieved by imagining physical or symbolic revenge. Experiment 2 showed similar effects for a non-aggressive conflict-resolution and, in addition, demonstrated a post-fulfillment reduction in actual aggressive behavior. Experiment 3 demonstrated that aggressive acts that do not constitute goal-fulfillment instead increase accessibility of aggression. Relations between our model and previous views on catharsis of aggression are discussed.     

Attributions About Achievement and Intentions About Further Study in Social Context

This project examined sources and consequences of attributions for achievement for boys and girls at co-ed (N = 663) and single-sex schools (N = 697). Overall attributions emphasised long and short term effort, over other personal (ability, liking) and social reasons (parents, teachers) or feeling good or bad on the day. Attributions were substantially similar for girls and boys, with particular variations in attributions to effort and ability at co-ed and not single-sex schools. Results suggested an illusory glow for boys more than girls in attributions to ability and effort for doing well in Mathematics and English, and traditional gender stereotyping in attributions to poor ability for not doing well in Mathematics. Results showed weak associations between attributions about effort and ability with intentions for Mathematics and English courses in senior high school. Findings suggest further research about personal and social sources of attributions in co-ed schools, and question the practical significance of attributions for achievement motivation.     

Head‐to‐head comparison of the predictive validity of personality types and dimensions

The utility of a configural type approach for predictions from personality is currently controversial. Configural types predict important personality correlates, but continuous dimensions based on the same data often fare much better in cross‐sectional head‐to‐head comparisons. However, many such comparisons can be considered unfair to the type approach, confound diverse differences between type and dimensional approaches, and rely only on cross‐sectional data. A sequence of analyses is reported that include fairer comparisons and deconfound differences due to the number of predictors, categorical versus dimensional predictors, dichotomized dimensions versus configural types, dimensional versus type criterion variables, and cross‐sectional versus longitudinal predictions. The results suggest incremental validity of configural types over dimensions only in a very few cases. Copyright © 2003 John Wiley & Sons, Ltd.     

Personality assessment in the Great Apes: Comparing ecologically valid behavior measures, behavior ratings, and adjective ratings

Three methods of personality assessment (behavior measures, behavior ratings, adjective ratings) were compared in 20 zoo-housed Great Apes: bonobos (Pan paniscus), chimpanzees (Pan troglodytes verus), gorillas (Gorilla gorilla gorilla), and orangutans (Pongo pygmaeus abelii). To test a new bottom-up approach, the studied trait constructs were systematically generated from the species’ behavioral repertoires. The assessments were reliable, temporally stable, and showed substantial cross-method coherence. In most traits, behavior ratings mediated the relations between adjective ratings and behavior measures. Results suggest that high predictability of manifest behavior is best achieved by behavior ratings, not by adjectives. Empirical evidence for trait constructs beyond current personality models points to the necessity of broad and systematic approaches for valid inferences on a species’ personality structure.     

Beyond global sociosexual orientations: a more differentiated look at sociosexuality and its effects on courtship and romantic relationships

Sociosexuality is usually assessed as the overall orientation toward uncommitted sex, although this global approach may mask unique contributions of different components. In a large online study (N = 2,708) and a detailed behavioral assessment of 283 young adults (both singles and couples) with a 1-year follow-up, the authors established 3 theoretically meaningful components of sociosexuality: past behavioral experiences, the attitude toward uncommitted sex, and sociosexual desire (all measured by a revised version of the Sociosexual Orientation Inventory). Discriminant validity was shown with regard to (a) their factorial structure, (b) sex differences, (c) many established correlates of sociosexuality, and (d) the prediction of observed flirting behavior when meeting an attractive opposite-sex stranger, even down to the level of objectively coded behaviors, as well as (e) the self-reported number of sexual partners and (f) changes in romantic relationship status over the following year. Within couples, the 3 components also showed distinct degrees of assortative mating and distinct effects on the romantic partner. Implications for the evolutionary psychology of mating tactics are discussed.     

Reduction in rat phosphatidylethanolamine binding protein-1 (PEBP1) after chronic corticosterone treatment may be paralleled by cognitive impairment: a first study

Chronic stress is associated with hippocampal atrophy and cognitive dysfunction. This study investigates how long-lasting administration of corticosterone as a mimic of experimentally induced stress affects psychometric performance and the expression of the phosphatidylethanolamine binding protein (PEBP1) in the adult hippocampus of one-year-old male rats. Psychometric investigations were conducted in rats before and after corticosterone treatment using a holeboard test system. Rats were randomly attributed to 2 groups (n = 7) for daily subcutaneous injection of either 26.8 mg/kg body weight corticosterone or sesame oil (vehicle control). Treatment was continued for 60 days, followed by cognitive retesting in the holeboard system. For protein analysis, the hippocampal proteome was separated by 2D electrophoresis (2DE) followed by image processing, statistical analysis, protein identification via peptide mass fingerprinting and gel matching and subsequent functional network mapping and molecular pathway analysis. Differential expression of PEBP1 was additionally quantified by Western blot analysis. Results show that chronic corticosterone significantly decreased rat hippocampal PEBP1 expression and induced a working and reference memory dysfunction. From this, we derive the preliminary hypothesis that PEBP1 may be a novel molecular mediator influencing cognitive integrity during chronic corticosterone exposure in rat hippocampus.     

An analogy between Hegel's theory of recognition and Ficino's theory of love

A widely debated question in current research centres on determining the precursors to G. W. F. Hegel's theory of recognition. Until now Fichte, Rousseau and Aristotle have been discussed. However, the present paper analyses a further surprising correspondence between Marsilio Ficino's theory of love and Hegel's theory of recognition. Here it is shown that Hegel studied Ficino in 1793 and that we can discover syntactical, semantical, and structural vestiges of Ficino's De amore II 8 in Hegel's early fragments on religion (1793) and love (1797), which are closely related to the general theory of recognition found in the Phenomenology of Spirit. Not only may this thesis be relevant for Hegel or Ficino scholarship, but it could also be a further indication that social theories with normative content are an integral characteristic of (early) modern self-consciousness.     

Disruption of order information by irrelevant items: a serial recognition paradigm

Irrelevant speech effect (ISE) is defined as a decrement in visually presented digit-list short-term memory performance due to exposure to irrelevant auditory material. Perhaps the most successful theoretical explanation of the effect is the changing state hypothesis. This hypothesis explains the effect in terms of confusion between amodal serial order cues, and represents a view based on the interference caused by the processing of similar order information of the visual and auditory materials. An alternative view suggests that the interference occurs as a consequence of the similarity between the visual and auditory contents of the stimuli. An important argument for the former view is the observation that ISE is almost exclusively observed in tasks that require memory for serial order. However, most short-term memory tasks require that both item and order information be retained in memory. An ideal task to investigate the sensitivity of maintenance of serial order to irrelevant speech would be one that calls upon order information but not item information. One task that is particularly suited to address this issue is serial recognition. In a typical serial recognition task, a list of items is presented and then probed by the same list in which the order of two adjacent items has been transposed. Due to the re-presentation of the encoding string, serial recognition requires primarily the serial order to be maintained while the content of the presented items is deemphasized. In demonstrating a highly significant ISE of changing versus steady-state auditory items in a serial recognition task, the present finding lends support for and extends previous empirical findings suggesting that irrelevant speech has the potential to interfere with the coding of the order of the items to be memorized.     

The Effects of Regulatory Focus on Braking Speed1

According to regulatory focus theory ( Higgins, 1997 ), promotion focus is concerned with accomplishments and aspirations leading to strategic eagerness; whereas prevention focus is concerned with safety and responsibilities leading to strategic vigilance. In this study, we investigate how regulatory focus theory can predict braking behavior in driving. In Study 1, participants' assessed regulatory focus strength as measured by chronic personality differences in regulatory focus predicted braking speed, in that chronic prevention‐oriented participants initiated braking earlier, as compared to promotion‐oriented people. In Study 2, we experimentally induced regulatory focus and showed that induced prevention focus enhanced braking speed (i.e., faster), as compared to induced promotion focus.
