Abstract
Bimodal audiovisual (AV) stimuli are detected or discriminated faster and more accurately than either visual or auditory unimodal stimuli. This effect is called audiovisual integration. Recently, researchers have been increasingly focused on the audiovisual integration of natural, auditory, and visual stimuli in real-world situations. There are some differences between audiovisual integration of naturalistic stimuli and non-naturalistic stimuli, such as the time of occurrence of audiovisual integration, and the neural mechanism. Factors affecting audiovisual integration in real-world situations are summarized here, with particular focus on temporal asynchrony and semantic matching. Stimuli of audiovisual integration in the real-world situation should be controlled strictly, especially emotional factors, familiarity factors, semantic matching, and the match of the naturalistic stimuli and non-naturalistic stimuli. In the future, researchers should study the influence of attention on audiovisual integration and the mechanism of audiovisual integration with naturalistic stimuli in the real-world situation.
