title = "Design and implementation of cancellation tasks for visual search strategies and visual attention in school children",
abstract = "We propose a computer-assisted cancellation test system (CACTS) to understand the visual attention performance and visual search strategies in school children. The main aim of this paper is to present our design and development of the CACTS and demonstrate some ways in which computer techniques can allow the educator not only to obtain more detailed information of visual search strategies but also to identify the problems of visual attention in school children. We have built a system that utilizes a graphic tablet connected to a PC to monitor the trace of visual search paths as well as the accuracy of visual search responses in school children during the test administration. The preliminary results show that there were no significant difference in correctness between sex, test layouts, and search patterns, except for the performance on different test forms (symbol vs. Chinese radical). The related factors that affect visual search behavior are also discussed.",

note = "Funding Information: Our findings suggest several interesting conclusions about visual search patterns. A structured Chinese context elicits more organized searching behavior, but a random array format does not. The reason may be that the structured Chinese form provides more explicit linguistic cues, leading to the usual visual search behavior of a participant as in reading task, while the random Chinese form does not. When the verbal cues are not obviously perceived by the participants, they tend to manage the stimuli as non-verbal with fast automatic attentional processing. The structured Chinese layout may arise more than the attentional networks in brain areas, but also verbal processing function (e.g. orthographic and phonemic processing). In other words, the stimulus layouts provide more explicit cueing than the stimulus materials. Reading habits play little role in dealing with such intense, speed- and performance-emphasized attentional tasks. This explanation is supported by Fernandez-Duque and Posner (2001) . They concluded that attentional networks exert energetic and selective control functions regardless of the stimulus material. ",
