Heading bias produced by simulation of the Layton et al. (2012) model (black curve) compared with that from the corresponding conditions in Experiment 3 (gray curve). The input to the model closely mimicked the conditions of Experiment 3 and the dot environment. The object (initially 10° × 10°) was simulated to move along a 15° trajectory with a 2 m lateral offset with respect to the observer's heading direction (0°). In the model dorsal medial superior temporal area (MSTd) template matching layer, 100 MSTd units were simulated with regularly spaced receptive fields centered along the extent of the 100° screen. Viewing duration was simulated by progressively removing input frames leading up to the end of the original sequence in proportions that matched those used in Experiment 3.
