Factors differentiating successful versus unsuccessful malingerers.

Relatively little is known about the processes in which "successful" malingerers engage to avoid detection. This study summarizes the response strategies used by participants (N = 540) instructed to feign a specific mental disorder while completing various self-report instruments designed to detect faking. Postexperiment questionnaires indicated that those who were able to appear symptomatic while avoiding being detected as feigning (n = 60) were more likely to endorse a lower rate of legitimate symptoms, to avoid overly unusual or bizarre items, and to base their responses on their own personal experiences.     

Does Risk Assessment Make a Difference? Results of Implementing the SAVRY in Juvenile Probation

An effective approach to reducing recidivism is, first, to identify a youth's risk of reoffending and then to match the intensity of interventions to that risk level. This pre-post quasi-experimental, prospective study compared 247 (pre) with 217 (post) adjudicated youths to examine the implementation of the Structured Assessment of Violence Risk in Youth (SAVRY) and its effects on case management practices in Louisiana's Caddo parish probation office. The results indicated that placement rates dropped by 50%, use of maximum levels of supervision dropped by almost 30%, and use of community services decreased except for high-risk youths, but only after the SAVRY was properly implemented. This shift towards more appropriate allocation of resources that are matched to risk level occurred without a significant increase in reoffending. The implications for implementation and for use of risk/needs assessment in juvenile probation are discussed. Copyright ? 2012 John Wiley & Sons, Ltd.     

An optimal adjustment procedure to minimize experiment time in decisions with multiple alternatives

Decisions between multiple alternatives typically conform to Hick’s Law: Mean response time increases log-linearly with the number of choice alternatives. We recently demonstrated context effects in Hick’s Law, showing that patterns of response latency and choice accuracy were different for easy versus difficult blocks. The context effect explained previously observed discrepancies in error rate data and provided a new challenge for theoretical accounts of multialternative choice. In the present article, we propose a novel approach to modeling context effects that can be applied to any account that models the speed–accuracy trade-off. The core element of the approach is “optimality” in the way an experimental participant might define it: minimizing the total time spent in the experiment, without making too many errors. We show how this approach can be included in an existing Bayesian model of choice and highlight its ability to fit previous data as well as to predict novel empirical context effects. The model is shown to provide better quantitative fits than a more flexible heuristic account.     

On the Knowledge of Politics and the Politics of Knowledge: How a Social Representations Approach Helps Us Rethink the Subject of Political Psychology

Fifty years ago, Serge Moscovici first outlined a theory of social representations. In this article, we attempt to discuss and to contextualize research that has been inspired by this original impetus from the particular angle of its relevance to political psychology. We argue that four defining components of social representations need to be taken into account, and that these elements need to be articulated with insights from the social identity tradition about the centrality of self and group constructions in order to develop original insights into political psychological phenomena. First, social representations are shared knowledge, and the way interpretations of the world are collectively elaborated is critical to the way people are able to act within the world. Second, social representations are meta‐knowledge, which implies that what people assume relevant others know, think, or value is part of their own interpretative grid, and that collective behavior can often be influenced more powerfully at the level of meta‐representations than of intimate beliefs. Third, social representations are enacted communication, which means that social influence is exerted by the factors that constrain social practices as much as by the discourse that interprets these practices. Fourth, social representations are world‐making assumptions: collective understandings do not only reflect existing realities but often bring social reality into being. Put together, these four components provide a distinctive theoretical perspective on power, resistance and conflict. The added conceptual value of this perspective is illustrated by showing how it allows revisiting ethnic conflict in the former Yugoslavia. We conclude with implications for research practices and discuss how the proposed model of social representations invites us to define new priorities and challenges for the methods used to study political psychological phenomena.     

The motivational value of listening during intimate and difficult conversations

Outcomes of conversations, including those dealing with controversial, deeply personal, or threatening disclosures, result not only from what is said but also from how listeners receive these messages. This article integrates the motivational framework of self-determination theory (SDT) and the expanding literature on interpersonal listening to explore the reasons why high-quality listening is so impactful during these conversations. We describe why high-quality listening is a specific and distinguishable autonomy-supportive motivational strategy, and argue that there is much to gain by considering that listening can satisfy basic psychological needs, in particular for autonomy and relatedness. We argue that SDT can help explain why high-quality listening is effective, especially in reducing defensiveness, bridging divides, and motivating change. The discussion focuses on ways motivation science can build more effective interventions for behavioral change by harnessing listening as an interpersonal strategy.     

Our Cosmic Insignificance

The universe that surrounds us is vast, and we are so very small. When we reflect on the vastness of the universe, our humdrum cosmic location, and the inevitable future demise of humanity, our lives can seem utterly insignificant. Many philosophers assume that such worries about our significance reflect a banal metaethical confusion. They dismiss the very idea of cosmic significance. This, I argue, is a mistake. Worries about cosmic insignificance do not express metaethical worries about objectivity or nihilism, and we can make good sense of the idea of cosmic significance and its absence. It is also possible to explain why the vastness of the universe can make us feel insignificant. This impression does turn out to be mistaken, but not for the reasons typically assumed. In fact, we might be of immense cosmic significance—though we cannot, at this point, tell whether this is the case.     

Influence of emotional valence and arousal on the spread of activation in memory

Controversy still persists on whether emotional valence and arousal influence cognitive activities. Our study sought to compare how these two factors foster the spread of activation within the semantic network. In a lexical decision task, prime words were varied depending on the valence (pleasant or unpleasant) or on the level of emotional arousal (high or low). Target words were carefully selected to avoid semantic priming effects, as well as to avoid arousing specific emotions (neutral). Three SOA durations (220, 420 and 720 ms) were applied across three independent groups. Results indicate that at 220 ms, the effect of arousal is significantly higher than the effect of valence in facilitating spreading activation while at 420 ms, the effect of valence is significantly higher than the effect of arousal in facilitating spreading activation. These findings suggest that affect is a sequential process involving the successive intervention of arousal and valence.     

Young children's non‐numerical ordering ability at the start of formal education longitudinally predicts their symbolic number skills and academic achievement in maths

Ordinality is a fundamental feature of numbers and recent studies have highlighted the role that number ordering abilities play in mathematical development (e.g., Lyons et al., 2014 ), as well as mature mathematical performance (e.g., Lyons & Beilock, 2011 ). The current study tested the novel hypothesis that non‐numerical ordering ability, as measured by the ordering of familiar sequences of events, also plays an important role in maths development. Ninety children were tested in their first school year and 87 were followed up at the end of their second school year, to test the hypothesis that ordinal processing, including the ordering of non‐numerical materials, would be related to their maths skills both cross‐sectionally and longitudinally. The results confirmed this hypothesis. Ordinal processing measures were significantly related to maths both cross‐sectionally and longitudinally, and children's non‐numerical ordering ability in their first year of school (as measured by order judgements for everyday events and the parents’ report of their child's everyday ordering ability) was the strongest longitudinal predictor of maths one year later, when compared to several measures that are traditionally considered to be important predictors of early maths development. Children's everyday ordering ability, as reported by parents, also significantly predicted growth in formal maths ability between Year 1 and Year 2, although this was not the case for the event ordering task. The present study provides strong evidence that domain‐general ordering abilities play an important role in the development of children's maths skills at the beginning of formal education.
