Assuming that motor action might help understanding underlying psychological processes, the current study attempts to identify deceptive behaviour by tracking the dynamics of hand movements during a computer-sorting task. Participants were asked to deceive by pretending that some of the items they “owned” have been paid for even though they were stolen. Analysis of participants’ streaming x-, y- mouse coordinates, during decision-making suggested that movement trajectories might indeed reveal underlying cognitive processes during deception. Statistical indicators of curvature and reaction times, including area-under- the-curve (AUC) and maximum deviation (MD) implied that there was as greater cognitive competition during deceptive than during truthful responding. Deceptive responds were made more slowly, with a stronger curvature tendency towards the alternate truthful answer. Non-deceptive responding was associated with shorter reaction times and more linear response trajectories. This supports prior research indicating that action dynamic measures might capture deceptive processes.

This study investigates the potential of computer mouse trajectories to identify deceptive behavior. By tracking hand movements during a computer-sorting task, the research aims to reveal whether movement dynamics can expose underlying cognitive processes involved in deception.
- The relationship between motor actions and cognitive processes, particularly in relation to deception.
- The use of mouse-tracking technology as a tool for capturing and analyzing action dynamics.
- The potential of movement trajectories to reveal the cognitive competition between truthful and deceptive responses.
- The identification of specific indicators within mouse trajectory data that might differentiate deceptive from truthful responses.
- The application of these findings to real-world scenarios involving deception, such as legal contexts.
