Postdiction occurs when later stimuli influence the perception of earlier stimuli. As the multisensory science field has grown in recent decades, the investigation of crossmodal postdictive phenomena has also expanded. Crossmodal postdiction can be considered (in its simplest form) the phenomenon in which later stimuli in one modality influence earlier stimuli in another modality (e.g., Intermodal Apparent Motion). Crossmodal postdiction can also appear in more nuanced forms, such as unimodal postdictive illusions (e.g., Apparent Motion) that are influenced by concurrent crossmodal stimuli (e.g., Crossmodal Influence on Apparent Motion), or crossmodal illusions (e.g., the Double Flash Illusion) that are influenced postdictively by a stimulus in one or the other modality (e.g., a visual stimulus in the Illusory Audiovisual Rabbit Illusion). In this review, these and other varied forms of crossmodal postdiction will be discussed. Three neuropsychological models proposed for unimodal postdiction will be adapted to the unique aspects of processing and integrating multisensory stimuli. Crossmodal postdiction opens a new window into sensory integration, and could potentially be used to identify new mechanisms of crossmodal crosstalk in the brain.
