A comparative study of a cued face search task is presented in this paper. Human participants and a computer model carried out a task in which they were required to locate a color-cued target face. Human-generated eye fixations and scanpaths were compared with those generated by the computational model. Throughout the comparison, we considered the similarities and dissimilarities between the two systems-performances. Their results show that the eye fixations in a valid cue search are highly correlated with the computer-generated fixation points in a valid cue search but not to those in random and invalid cue searches. Moreover, the comparison between human- and computer-generated scanpaths showed that the scanpath that links the fixation points is not randomly generated. Our results imply that eye movement is accomplished not only by cue-driven activation, but also by a spatial strategy.
