Using individual differences to understand saccade-pursuit interactions

Due to the foveal organization of our visual system, eye movements are an essential part of perception and are studied across a wide range of different research areas. Across all areas typically only saccadic or only pursuit eye movements are measured in different tasks and behavior is averaged across observers. In this study we want to use interindividual variability to understand the naturally occurring saccade-pursuit interactions. A large group of participants will perform a set of standard oculometric (saccade and pursuit) and psychometric measurements with different relevant sensory information (position and velocity). We will correlate these basic measurements across observers with differences in saccade-pursuit interactions to understand which factors drive behavioral differences. We want to test whether interindividual difference vary across different eye movements or across different relevant sensory information to gain insight into the structure of the oculomotor system. other
