Effects of visual cues on scene-relative object motion judgments and concurrent heading estimation from optic flow.

ABSTRACT: During self-movement, the visual system uses optic flow to identify scene-relative object motion and estimate the direction of self-movement (heading). Although both processes rely on optic flow, their relationship and the conditions under which independent object motion biases heading estimation remain unclear. The causal inference model predicts that misjudging object motion leads to its integration into heading estimation, causing errors in heading estimation, whereas correct judgments reduce these errors. However, most studies have examined these processes independently. Here we used a dual-task paradigm to investigate how visual cues affect the judgment of scene-relative object motion direction and concurrent heading estimation. Participants viewed a 90° × 90° display simulating self-
