While multisensory cues improve performance in tasks involving stationary stimuli, the perception of multisensory motion remains unclear. Here, we investigated whether motion cue integration occurs and whether audiovisual motion perception is modulated by attention, trial history, and stimulus statistics. Forty-eight adults performed left\u2013right direction discriminations with auditory (A), visual (V), and audiovisual (AV) motion, with attention cued to A, V, or AV. Visual estimates were more reliable than auditory (smaller variance), and AV performance exceeded either modality alone. A reliability-weighted maximum-likelihood model closely predicted AV thresholds for congruent cues, indicating near-optimal integration. Under cue conflict, AV judgments were dominated by vision. A follow-up experiment using congruence discrimination points to causal inference as a main driver of cross-modal and individual variability in conflict trials. Additionally, analyses of prior responses (serial dependence) revealed measurable trial-history effects that shifted directional judgments in a modality-specific manner. Together, our results point to key differences and similarities in the mechanisms of auditory and visual motion perception, both shaped by attention and prior history.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Neuroscience brown bag Adam Tiesman Graduate Student Date: Friday, November 14, 2025 Time: 1:25- 2:15pm Location: 316 Wilson Hall Behavioral mechanisms underlying the integration of auditory and visual motion Accurate motion perception is crucial for navigating complex environments, where sensory information is often derived from multiple modalities.
