According to recent research on laypersons' punitive attitudes people's sentencing decisions are primarily driven by a desire for retribution. The research designed to test this notion, however, can be criticized for suffering from several limitations. Three online-based studies were conducted with samples from Western Europe with the aim of replicating the findings of Carlsmith (J Exp Soc Psychol 42:437-451, 2006) in which participants' punishment motives were inferred from their behavior in a process tracing task. In the present research, this approach was adopted and modified in order to provide a more conservative test for the notion that people mainly care about retribution. Although these modifications strongly influenced the overall pattern of results, retribution still was the most important punishment motive in all three studies.

Claims of crime-related amnesia appear to be common. Using a mock crime approach, the diagnostic power of seven symptom validity instruments was investigated. Sixty participants were assigned to three conditions: responding honestly; feigning crime-related amnesia; feigning amnesia with a warning not to exaggerate. High sensitivity and specificity were obtained for the Structured Inventory of Malingered Symptomatology, the Amsterdam Short-Term Memory Test, and the Morel Emotional Numbing Test. Only three warned malingerers went undetected. The results demonstrate that validated instruments exist to support forensic decision making about crime-related amnesia. Yet, warning may undermine their effectiveness, even when using a multi-method approach.

Previous studies have shown that the harm caused by crime affects punitive reactions even if differences in the degree of harm are merely accidental. However, it remains unclear whether the effect is direct or whether it is mediated by attributed responsibility or blame. Participants were 303 university students who listened to 4 case vignettes (hetweensubjects design). Half received information about a completed crime and half about an accidentally uncompleted crime. Crime type was either Fraud or rape. The results suggest that individuals consider the actual harm to a significantly greater extent than attribution theory would predict. Moreover, the link between harm and punishment was virtually not mediated by attributed blame and not moderated by individual differences in morality. Future studies should investigate whether the ham--punishment link is a result of an automatic act of retaliation or a desire to compensate for the harm done to the victim (restorative justice).

The present research aims to explore the mechanisms underlying response bias in detection of deception. In addition to examining the predictive value of generalized communicative suspicion (GCS), age, and professional experience, the present approach also investigates the role of error weighting by testing the hypothesis that a greater concern about Misses is associated with a lie bias. In Study 1, we analyzed samples of (a) students, (b) police trainees, and (c) police officers. Results revealed an asymmetrical error weighting as the strongest predictor of response bias. Supporting our hypothesis, participants who were more concerned about False Alarms were particularly truth biased, whereas a lie bias was observed among those who were more concerned about Misses. In Study 2, we manipulated the error weighting in order to test its causal relation to response bias. Results again show the predictive value of asymmetrical error weighting for response bias in deception detection, and indicate that the effects of the manipulation are moderated by individuals' habitual error weighting.
