Conceptualizing psychopathic traits from an evolutionary-based perspective: An empirical study in a community sample of boys and girls

Although psychopathy has historically been associated with a lack of emotion, recent research has suggested that psychopathy may represent a tendency to externalize the experience of unpleasant emotions, including shame, which could be seen as an adaptive strategy within an evolutionary framework. However, more empirical research is needed to build on this argument. This study tested a novel evolutionary-based model involving pathways associating the impact of harsh rearing experiences (warmth and safeness experiences and traumatic shameful experiences) with psychopathic traits as well as the indirect effects of external shame and shame coping strategies in this association. This study also tested the invariance of this model across gender. A youth community sample (N = 703; 58.9% girls) completed self-report questionnaires on the impact of harsh rearing experiences, external shame, shame coping strategies, and psychopathic traits. The results suggested that the impact of harsh rearing experiences was directly and indirectly (through external shame and shame coping strategies) associated with psychopathic traits. The model partially explained the endorsement of psychopathic traits in boys and girls, although gender differences were found in some of the pathways. These findings offer support for conceptualizing psychopathic traits as an adaptive strategy to cope with the impact of harsh rearing experiences, opening new perspectives for prevention and treatment.

     

Effects of Modeling the Heterogeneity on Inferences Drawn from Multilevel Designs

This article uses Monte Carlo techniques to examine the effect of heterogeneity of variance in multilevel analyses in terms of relative bias, coverage probability, and root mean square error (RMSE). For all simulated data sets, the parameters were estimated using the restricted maximum-likelihood (REML) method both assuming homogeneity and incorporating heterogeneity into multilevel models. We find that (a) the estimates for the fixed parameters are unbiased, but the associated standard errors are frequently biased when heterogeneity is ignored; by contrast, the standard errors of the fixed effects are almost always accurate when heterogeneity is considered; (b) the estimates for the random parameters are slightly overestimated; (c) both the homogeneous and heterogeneous models produce standard errors of the variance component estimates that are underestimated; however, taking heterogeneity into account, the REML-estimations give correct estimates of the standard errors at the lowest level and lead to less underestimated standard errors at the highest level; and (d) from the RMSE point of view, REML accounting for heterogeneity outperforms REML assuming homogeneity; a considerable improvement has been particularly detected for the fixed parameters. Based on this, we conclude that the solution presented can be uniformly adopted. We illustrate the process using a real dataset.     

Suppression-induced forgetting on a free-association test

The repeated suppression of thoughts in response to cues for their expression leads to forgetting on a subsequent test of cued recall (Anderson & Green, 2001). We extended this effect by using homograph cues and presenting them for free association following suppression practice. Cue–target pairs were first learned under integrating imagery instructions; then in the think/no-think phase students practised suppressing thoughts connected to some homograph cues, with or without the assistance of thought substitutes that changed their meaning. Below-baseline forgetting on the subsequent free-association test was found in the production of suppressed targets. Following aided suppression this effect was also obtained in the production of other responses denoting the target-related meaning of the homograph cues. Discussion emphasises the ecological value of the test; rarely do people deliberately attempt recall of unwanted thoughts.
