T1  - Post-execution monitoring in dishonesty
JF  - Psychological Research
N2  - When telling a lie, humans might engage in stronger monitoring of their behavior than when telling the truth. Initial evidence has indeed pointed towards a stronger recruitment of capacity-limited monitoring processes in dishonest than honest responding, conceivably resulting from the necessity to overcome automatic tendencies to respond honestly. Previous results suggested monitoring to be confined to response execution, however, whereas the current study goes beyond these findings by specifically probing for post-execution monitoring. Participants responded (dis)honestly to simple yes/no questions in a first task and switched to an unrelated second task after a response–stimulus interval of 0 ms or 1000 ms. Dishonest responses did not only prolong response times in Task 1, but also in Task 2 with a short response–stimulus interval. These findings support the assumption that increased monitoring for dishonest responses extends beyond mere response execution, a mechanism that is possibly tuned to assess the successful completion of a dishonest act.

T1  - Validity of the reaction time concealed information test in a prison sample
JF  - Frontiers in Psychiatry
N2  - Detecting whether a suspect possesses incriminating (e.g., crime-related) information can provide valuable decision aids in court. To this means, the Concealed Information Test (CIT) has been developed and is currently applied on a regular basis in Japan. But whereas research has revealed a high validity of the CIT in student and normal populations, research investigating its validity in forensic samples in scarce. This applies even more to the reaction time-based CIT (RT-CIT), where no such research is available so far. The current study tested the application of the RT-CIT for an imaginary mock crime scenario both in a sample of prisoners (n = 27) and a matched control group (n = 25). Results revealed a high validity of the RT-CIT for discriminating between crime-related and crime-unrelated information, visible in medium to very high effect sizes for error rates and reaction times. Interestingly, in accordance with theories that criminal offenders may have worse response inhibition capacities and that response inhibition plays a crucial role in the RT-CIT, CIT-effects in the error rates were even elevated in the prisoners compared to the control group. No support for this hypothesis could, however, be found in reaction time CIT-effects. Also, performance in a standard Stroop task, that was conducted to measure executive functioning, did not differ between both groups and no correlation was found between Stroop task performance and performance in the RT-CIT. Despite frequently raised concerns that the RT-CIT may not be applicable in non-student and forensic populations, our results thereby do suggest that such a use may be possible and that effects seem to be quite large. Future research should build up on these findings by increasing the realism of the crime and interrogation situation and by further investigating the replicability and the theoretical substantiation of increased effects in non-student and forensic samples.
