dc.description.abstractThis paper investigates the effect of individual differences in human cognition on user performance in CAPTCHA tasks. In particular, a three-month ecological valid user study was conducted with a total of 107 participants who interacted with a text-recognition and an image-recognition CAPTCHA mechanism. The study included a series of psychometric tests for eliciting users' speed of processing, controlled attention and working memory capacity, with the aim to examine the effect of these cognitive processes on the efficiency and effectiveness of user interactions in CAPTCHA tasks. Preliminary results provide interesting insights for the design and deployment of adaptive CAPTCHA mechanisms based on individual differences in cognitive processing since it has been initially shown that specific cognitive processing abilities of individuals could be a determinant factor on the personalization of CAPTCHA mechanisms. © 2013 Springer-Verlag Berlin Heidelberg.en
