Two experiments were conducted in order to examine factors that might influence the motivation of guilty and informed innocent examinees to either cope or cooperate with the Guilty Actions Test. Guilty participants committed a mock-crime and informed innocent participants handled the critical items of the crime in an innocent context. In Experiment 1 the participants were led to believe that the prospects of being found innocent on the test were either high or low. In Experiment 2 the participants were led to believe that the test was either highly accurate or of questionable validity. Results indicated that for both guilty and informed innocent participants low prospects of success and low detection efficacy of the test were associated with enhanced physiological responses to the critical information, whereas high prospects of success and high detection efficacy were associated with attenuated physiological responses. Theoretical and practical implications of the results are discussed.

Studies on the genetic basis of bicuspid aortic valve (BAV), characterized by a configuration of the aortic valve with two leaflets instead of three, are insufficient. This study aimed to elucidate the possible relationship between BAV and TGF-β1 gene expression levels. Forty-eight pediatric patients diagnosed with isolated BAV and 50 healthy children with innocent heart murmurs were included in the study.

This experiment explored the influence of facial attractiveness and trustworthiness on guilty judgments. We recruited 128 participants, randomly assigned to high and low time pressure conditions to act as judges in a simulated case. Participants judged nine male faces from the Chicago Face Database with three attractiveness levels (unattractive, neutral and attractive), featuring a 2 × 3 mixed factorial design, with consistent standardized average levels of face trustworthiness.

Cognitive and social factors can deteriorate eyewitness identification performance in children and older adults. An identification procedure that mitigates the effect of such factors could be beneficial for child and older adult witnesses. In a field experiment, we mapped identification performance in a large community sample (N = 1239) across the lifespan (ages 6-79 years) for two different identification procedures: classic lineups and reaction time-based Concealed Information Test (RT-CIT).

Prior research has investigated ways to optimize identification performance, but an open question concerns exactly what variable should be optimized. One reasonable way to optimize performance is to maximize discriminability, which is achieved by increasing correct identifications of guilty suspects while simultaneously decreasing false identifications of innocent suspects. Another reasonable way to optimize performance is to maximize the information about the guilt or innocence of the suspect, which is best achieved by ensuring that a confidence rating is always made to the suspect.

Article Synopsis
- * 57 participants were divided into guilty and innocent groups, and the collected data demonstrated that all indicators could consistently differentiate between the two groups, with varying degrees of accuracy.
- * The combined use of these multiple indicators significantly improved detection efficiency (AUC = 0.96), highlighting the advantages of using a broader approach for concealed information detection in CIT.
