Abstract
ABSTRACTMultiple-identity tracking (MIT) is a dynamic task in which observers track multiple moving objects of distinct identities and then report the location of each target object. The present study examined participant’ eye movements during MIT in order to investigate the relationship between eye movements and attentional performance during the task. The results showed that fixations were predominately directed to individual targets during tracking. When successfully landed on targets, the fixations dwelled for longer duration; otherwise, they were terminated quickly. As the attentional demands for processing the targets increased, fixations landed on the targets more frequently while fixations outside targets decreased both in number and duration. The attentionally more demanding targets were fixated more frequently than the attentionally less demanding ones. The most recently fixated target was tracked with higher performance, while the tracking accuracy for the more previously fixated targets gradually decreased. Taken together, the results indicate that fixations are tightly coupled with attention during MIT, switching serially from target to target for refreshing each object representation to facilitate the tracking of identities and locations of multiple targets.
