Experiments involving participant’s response recording by way of pressing buttons are quite common. This simple method allows estimation of such crucial parameters as response time and response correctness. However, more detailed analysis of behavioral responses is needed in some cases. Crucial aspects within the cognitive control research field include the conflict before decision-making, error detection after response commission and internal uncertainty. The present research was carried out to validate and estimate the informativeness of a new response recording method using mouse tracking. Erroneous responses versus correct responses during performance of the auditory condensation task were analyzed and then compared with the results of a previous similar experiment where buttons were used for response recording. It was found that the time of starting mouse movements corresponds to response times measured by way of participants pressing a button. In addition, several parameters of mouse cursor trajectories were proposed as indirect measures of participant’s certainty, including mouse movement time, track curvature (deviation from a linear one), start angle and start velocity of mouse cursor, and finishing angle of response. The obtained results allow us to conclude that the response recording method using the mouse tracking technique provide highly informative behavioral data which can help to detect internal uncertainty. Thus, the new method of response recording appears to be very useful for cognitive control research.
