ABSTRACT
This chapter reviews a demonstration of how to take advantage of Systems Factorial Technology (SFT) to study the perceptual comparison and decision process in change detection. It discusses how detection relates to change blindness. Change blindness is more likely due to failure in retrieval and comparison. This account is consistent with visual memory theory. The double factorial design necessary to conduct the SFT analyses is relatively easy to implement in change detection. The traditional signal detection account is less likely because there is no evidence for coactive processing, and the signal detection model does not predict that the manipulation of relative saliency affects the order of multiple-signal processing. Multiple-signal processing is important to study how individual differences in processing capacity are related to the way information is processed. Yang and colleagues demonstrated that individual differences in processing capacity are related to the participants' working memory capacity and their personality traits.
