摘要：SummaryHumans visually inspect the world with their fovea and select new parts of the scene using saccadic eye movements. Foveal inspection and the decision of where and when to look next proceed simultaneously, but there is mixed evidence concerning their independence. Here, we tested their interdependence using drift-diffusion modeling. Participants first made a saccade to a predetermined inspection target and subsequently decided between two selection targets. We found that the inspected target’s meaningfulness and the opportunity to preview it peripherally affects fixation durations and the upcoming saccadic selection. Drift-diffusion modeling showed that meaningfulness and the absence of peripheral preview can both delay the subsequent saccadic decision process and affect the rate at which peripheral information is accumulated. Our results thus show that foveal inspection and peripheral selection are dependent on each other and that peripheral information can be maintained across the saccade to influence subsequent eye movement decisions.Graphical abstractDisplay OmittedHighlights•Foveally inspected targets affect the decision between targets in the periphery•Meaningful foveal targets delay decision onset and affect decision outcome•Prior peripheral preview of inspected targets modulated effects on decision outcomeBiological sciences; Neuroscience; Cognitive neuroscience
