Abstract: In order to mitigate dictionary attacks or similar undesirable automated attacks to information systems, developers mostly prefer using CAPTCHA challenges as Human Interactive Proofs (HIPs) to distinguish between human users and scripts. An appropriate use of CAPTCHA requires a setup balance between robustness and usability during the design of a challenge. The previous research reveals that most of the usability studies have used accuracy and response time as measurement criteria for quantitative analysis. The present study aims at applying optical neuroimaging techniques for the analysis of CAPTCHA design. In particular, fNIRS (Functional Near Infrared Spectroscopy) is a neuroimaging technique used for mental workload analysis by means of analyzing hemodynamic responses on brain. The present study reports an experimental investigation in which 25 participants solved a group of text-based CAPTCHA with various visual characteristics.

Abstract: Understanding the how the cognitive system processes information in real time is one of the key concerns for researchers in experimental psychology and cognitive science. Several measures and software tools have been proposed to explore different aspects of cognitive processing phenomena. One of these methods, mouse-tracking, helps researches to trace the participants’ hand movements during cognitive tasks which may be a reflection of their mental processes. Mouse-tracking method allows researchers to collect data about the dynamic unfolding of motor responses, and thus, provides additional insights about the process through which outcome-based measures such as reaction times or error rates are observed. Although the mental processes are treated as having discrete labels in traditional cognitive science, the new perspective indicates continuous processing of mind trajectories. Continuous and probabilistic representation of mental phenomena points out the continuous trajectory of the mind which travels through the set of possible brain states. Mouse Tracker’s real-time response data may shed light on continuous perspective of mind trajectories and temporal dynamics of cognitive processes. From this point of view the Simon Task which known as “stimulus-response compatibility effect” will be implemented with Mouse Tracker software. The collected multiple response alternatives will be analyzed in the light of continuous processing phenomena in an effort to shed further light into how the temporal dynamics of cognitive and motor processes contribute to the Simon effect.
