Straightening priority out

In recent work, Louis deRosset (Philosophical Studies 149:73?C97, 2010) has argued that priority theorists, who hold that truths about macroscopic objects can be metaphysically explained without reference to such things, cannot meet an independently motivated constraint upon good explanation. By clarifying the nature of the priority theorist??s project, I argue that deRosset??s argument fails to establish its conclusion.     

Stereotype threat: Antecedents and consequences for working women

Three studies investigated antecedents and consequences of stereotype threat for female employees. The results of Studies 1 and 2 suggest that social comparisons with men are associated with feelings of stereotype threat whereas social comparisons with women are not. Stereotype threat, in turn, was associated with conflict surrounding women's identity as female employees and with decreased perceived likelihood of achieving career goals. Study 3 extended these findings by demonstrating that feelings of stereotype threat are also negatively related to workplace attitudes and turnover intentions. Furthermore, the effect of stereotype threat on these job attitudes and intentions was itself mediated by identity conflict and perceived likelihood of achieving career goals. Implications and limitations of these findings are discussed. Copyright © 2010 John Wiley & Sons, Ltd.     

The evolution and psychology of self-deception

In this article we argue that self-deception evolved to facilitate interpersonal deception by allowing people to avoid the cues to conscious deception that might reveal deceptive intent. Self-deception has two additional advantages: It eliminates the costly cognitive load that is typically associated with deceiving, and it can minimize retribution if the deception is discovered. Beyond its role in specific acts of deception, self-deceptive self-enhancement also allows people to display more confidence than is warranted, which has a host of social advantages. The question then arises of how the self can be both deceiver and deceived. We propose that this is achieved through dissociations of mental processes, including conscious versus unconscious memories, conscious versus unconscious attitudes, and automatic versus controlled processes. Given the variety of methods for deceiving others, it should come as no surprise that self-deception manifests itself in a number of different psychological processes, and we discuss various types of self-deception. We then discuss the interpersonal versus intrapersonal nature of self-deception before considering the levels of consciousness at which the self can be deceived. Finally, we contrast our evolutionary approach to self-deception with current theories and debates in psychology and consider some of the costs associated with self-deception.     

Efficient Hessian computation using sparse matrix derivatives in RAM notation

This article proposes a new, more efficient method to compute the minus two log likelihood, its gradient, and the Hessian for structural equation models (SEMs) in reticular action model (RAM) notation. The method exploits the beneficial aspect of RAM notation that the matrix derivatives used in RAM are sparse. For an SEM with K variables, P parameters, and P′ entries in the symmetrical or asymmetrical matrix of the RAM notation filled with parameters, the asymptotical run time of the algorithm is O(P?′?K ²?+?P ² K ²?+?K ³). The naive implementation and numerical implementations are both O(P ² K ³), so that for typical applications of SEM, the proposed algorithm is asymptotically K times faster than the best previously known algorithm. A simulation comparison with a numerical algorithm shows that the asymptotical efficiency is transferred to an applied computational advantage that is crucial for the application of maximum likelihood estimation, even in small, but especially in moderate or large, SEMs.     

Reading about explanations enhances perceptions of inevitability and foreseeability: a cross-cultural study with Wikipedia articles

In hindsight, people often perceive events to be more inevitable and foreseeable than in foresight. According to Causal Model Theory (Nestler et al. in J Exp Psychol Learn Mem Cogn 34: 1043–1054, 2008), causal explanations are crucial for such hindsight distortions to occur. The present study provides further empirical support for this notion but extends previous findings in several ways. First, ecologically valid materials were used. Second, the effect of causal information on hindsight distortions was investigated in the realm of previously known events. Third, cross-cultural differences in reasoning (analytic vs. holistic) were taken into account. Specifically, German and Vietnamese participants in our study were presented with Wikipedia articles about the nuclear power plant in Fukushima Daiichi, Japan. They read either the version that existed before the nuclear disaster unfolded (Version 1) or the article that existed 8 weeks after the catastrophe commenced (Version 2). Only the latter contained elaborations on causal antecedents and therefore provided an explanation for the disaster. Reading that version led participants to perceive the nuclear disaster to be more likely inevitable and foreseeable when compared to reading Version 1. Cultural background did not exert a significant effect on these perceptions. Hence, hindsight distortions were obtained for ecologically valid materials even if the event was already known. Implications and directions for future research are discussed.     

Couples' evaluations of fatherhood in different stages of the family life cycle

Fathers' and mothers' views on mothers' satisfaction with paternal behaviour as well as the respective processes of origination were studied in 393 cohabiting couples from three different stages of the family life cycle. Data on paternal competence and the couples' relationship characteristics were included as predictors in multiple regression analyses, and the stages of the family life cycle were taken into account with multigroup regression analyses. Results showed that the mothers were more satisfied with paternal behaviour than the fathers thought the mothers were. Moreover, mothers were satisfied when the fathers were willing to spend time with the child, whereas fathers thought that their partners were satisfied when they were able to establish and maintain a relationship with the child. Couple relationship satisfaction had a consistent impact on fathers' views, whereas it was not relevant to mothers' views unless the oldest child had reached adolescence.     

Granger Causality—Statistical Analysis Under a Configural Perspective

The concept of Granger causality can be used to examine putative causal relations between two series of scores. Based on regression models, it is asked whether one series can be considered the cause for the second series. In this article, we propose extending the pool of methods available for testing hypotheses that are compatible with Granger causation by adopting a configural perspective. This perspective allows researchers to assume that effects exist for specific categories only or for specific sectors of the data space, but not for other categories or sectors. Configural Frequency Analysis (CFA) is proposed as the method of analysis from a configural perspective. CFA base models are derived for the exploratory analysis of Granger causation. These models are specified so that they parallel the regression models used for variable-oriented analysis of hypotheses of Granger causation. An example from the development of aggression in adolescence is used. The example shows that only one pattern of change in aggressive impulses over time Granger-causes change in physical aggression against peers.     

Cyber bullying among children with neurodevelopmental disorders: A systematic review

Children and young adults with neurodevelopmental disorders (ND) are at increased risk of bullying compared to typically developing peers. It is still unclear to what extent they are involved in cyber bullying. This systematic review aimed at studying the prevalence of cyber bullying as perpetrators, victims, or both (“bully-victims”) among students with ND in a school setting and in need of special education. The Web of Science, Scopus, ERIC, PsycINFO, PubMED, and Cochrane databases were searched including a manual search of reference lists, until February 24, 2018. Eight studies conducted in Europe, North America, the Middle East, and Australia were included reporting a prevalence of cyber-victimization among students with ND of 0%–41%, a prevalence of cyber-perpetration of 0%–16.7%, and a prevalence of bully-victims of 6.7%. Three out of five studies using control groups showed that students with ND might be more involved in cyber bullying overall compared to typically developing students. Students in segregated school settings report slightly higher prevalence rates of cyber bullying compared to students with ND in inclusive school settings, especially among girls. When comparing prevalence rates among studies using the same definition, we found similar prevalence rates. There was a tendency towards students with ND being more involved in cyber bullying compared to typically developing students, but this needs to be confirmed in future studies that should include control groups with typically developing students as well as validated and standardized measurements of cyber bullying and ND diagnoses.
