Abstract

Recently, a large number of studies have shown the analysis of hand motion can be used as implicit measure of the cognitive processes underlying a task and it can be useful to understand the dynamics of a wide range of psychological processes. In other words, hand-motor tracking can provide in real-time a good trace of mind processes. Because cognition is largely involved in the process of lie, it is reasonable to think that the analysis of hand movements can be a good implicit measure also to study the cognitive mechanisms involved in lying. Here we present a series of studies in which it is proves that, through the kinematic analysis, it is possible to reach a high accuracy in discriminate between true and false information declared by subjects. The proposed method consists in a memory detection technique, which investigates the truthful or untruthful nature of the memory of the information declared, using implicit measures from mouse movements. We employed kinematic analysis of the mouse movements to identify implicit signatures of deception in a wide range of topics, as for example the identification of true or fake events reported by subjects. This technique could have a large number of implications, particularly in forensic field, where the verification of the veracity of the events described is an issue still unresolved.
