There are two opposing models of how the serial deployment of attention is controlled in visual search: "memory-driven model" and "memory-free model". The former suggests that attention is controlled by a visual short-term memory and the latter assumes that attention is controlled by no memory. This paper gives two evidences for the memory-driven model. First, the previously checked items were memorized and inhibited in serial visual search, which is called "inhibition of return". This mechanism can improve the efficiency of search by preventing reexamination of rejected distractors. Second, the previously displayed distractors were memorized to discriminate newly presented items from them, which is called "visual marking". This mechanism is useful for discrimination between newly appeared objects and background. We discuss about what kind of representation on memory is used in these mechanisms.
