17:25-17:45 The critical temporal delay between gaze shift and visual feedback for maintaining a sense of agency: gaze-contingent multiresolutional display study

The purpose of this research is to determine the critical temporal delay from a user's eye-gaze input to a computer's visual feedback for maintaining a sense of agency. we performed a simple visual search for Chinese characters with a gaze-contingent foveated window which was updated with temporal delay from a participant's gaze shift. From above 200 ms temporal delay, self-reported SOA scores and calculated controllability scores of the window were lowest and distribution of fixation duration altered, suggesting that temporal delay should be kept within 200 ms to maintain the user’s SOA and controllability when eye-gaze input devices are designed.

17:45-18:05 The relationship between time pressure and opting out of decision making

Several studies have examined the effect of sensing time on the ability to make decisions under pressure. In this study, we examined the suggested correlation between timing ability and decision accuracy, and the relationship between time pressure and opting out of decision making. To do so, we designed an adaptation of the decision-making task under time pressure, with an additional response option to skip a trial. The presented research paradigm proved to be suitable for investigations of meta-decision-making, that is, how people manage their decision-making as a function of time and different sets of response options.

After the talks, we will get together in Kazuo's office, Room 709 on the 7th Floor of Building 3.
