Anchoring,Familiarity, and Confidence in the Detection of Deception

Anchoring in judgments is the tendency for the final judgment to be biased toward the initial estimate through insufficient adjustment. In the context of the detection of deception, it has been used to explain phenomena such as negative absolute leakage and the truthfulness bias. We examined the influence of order of judgment type on attitude ratings, accuracy, and the truthfulness bias. Receivers of communications should tend to anchor their judgments on the sender's attitudinal position if asked to make attitude judgments first and on the sender's behavior if asked to make truthfulness judgments first. The results partly support these predictions. Negative absolute leakage, accuracy, and the truthfulness bias were not significantly different for those who made attitude judgments before truthfulness judgments. However, results show that accuracy decreased as the session continued and there was no difference in the confidence with which truth and deception judgments were made, but there was a positive relation between confidence and truthfulness bias.     

Environmental sound recognition by timbre in children with Williams syndrome

Anecdotal reports have described children with Williams syndrome (WS) as presenting outstanding skills for recognizing environmental sounds by their timbre. This has led to suggest that the skills for environmental sound recognition by timbre are highly developed in WS. Furthermore, the term hypertimbria has been proposed to refer to this feature. However, no academic research has assessed these skills in WS. This study therefore aimed to contrast the reports on the highly developed skills for environmental sound recognition by timbre in children with WS. An environmental sound recognition task was administered to children with WS, children with Down syndrome of the same chronological age and cognitive level, and chronological age-matched typically developing children. Participants with WS performed significantly lower than their typically developing peers and no significant differences were found between the WS and Down syndrome groups. Unlike previous reports, this study points out that in WS environmental sound recognition by timbre does not constitute a phenotypic strength either in absolute or relative terms. Results suggest that children with WS do not present hypertimbria or preserved skills for timbre recognition. We discuss the implications of these results for theories of cognitive modularity.     

Empathy deficits and sexual offending: A model of obstacles to empathy

Theoretical models of the role of empathy in sexual offending agree on five components relevant to the experience of empathy: a respectful and compassionate orientation to others, perspective taking, affective responding, the ability to manage personal distress, and situational factors. We identify overlap between these components of the empathic process and established risk factors for sexual offending and create a model detailing potential blocks to the empathic process during sexual offending. The model has external consistency and useful implications for interventions with sex offenders. Viewed in the light of this model, we argue that current sex offender treatment programs spend a disproportionate amount of time examining empathy for past victims. We recommend, instead, that treatment aims to enhance offenders' abilities in relation to the components of the empathic process more generally, using creative and engaging techniques akin to those used to develop “victim empathy”.
