“…More recently, it has been demonstrated that a sound presented in close temporal proximity to a visual stimulus may be perceived as occurring simultaneously with the visual stimulus. Known as the ''temporal ventriloquism effect,'' this phenomenon can correct for asynchronous auditory and visual inputs by binding visual stimuli into temporal alignment with the appropriate auditory events (19)(20)(21)(22). This phenomenon has not been investigated systematically in freely behaving animals in the field.…”

The mechanisms by which the brain binds together inputs from separate sensory modalities to effect a unified percept of events are poorly understood. This phenomenon was studied in males of the dart-poison frog Epipedobates femoralis. These animals physically and vigorously defend their territories against conspecific calling intruders. In prior field studies with an electromechanical model frog, we were able to experimentally evoke this aggressive behavior only when an auditory cue (advertisement call) was presented simultaneously with a visual cue (vocal-sac pulsations). In the present field experiments, we used a modified version of the electromechanical model frog to present territorial males with visual and auditory cues separated by experimentally introduced temporal delays or spatial disparities to probe temporal and spatial integration in this animal. In temporal integration experiments, bimodal stimuli with temporal overlap during calling bouts consistently evoked aggressive behavior; stimuli lacking bimodal temporal overlap were relatively ineffective at the same task. In spatial integration studies, despite presenting the components of the bimodal stimulus with an initial spatial disparity of up to 12 cm, fighting behavior persisted. These results demonstrate that temporal and spatial integration may be reliably estimated in a freely behaving animal in its natural habitat and that we can use aggressive behavior in this species as an index of cross-modal integration in the field.animal communication ͉ territorial defense ͉ anuran ͉ amphibian ͉ Dendrobatidae

“…For temporal judgments, however, such as that studied by Shams et al [10] and others (e.g. [12]), the situation is reversed and audition, being the more appropriate modality, usually dominates over vision. However, the terminology used, 'modality precision' and 'modality appropriateness', is misleading because it is not the modality itself or the stimulus that dominates.…”

“…These signals have different processing latencies due to dissimilarity in physical and neural transmission (Fain, 2003;King, 2005;King & Palmer, 1985;Spence & Squire, 2003). The human brain overcomes these differences by allowing the auditory and visual information to be processed as pertaining to the same event even when the signals are physically asynchronous (Dixon & Spitz, 1980).…”

Many discussions of biological motion perception involve a description of observers’ attunements for recognizing gender, emotion, action, and identity from point-light displays. This chapter describes an often-neglected determinant of biological motion perception: the role of expertise. First, the authors describe how variability among observers is essential for developing a comprehensive theory of biological motion perception. Then, they describe how the distributed network of brain areas devoted to biological motion perception provides an opportunity for this brain network to be applied to new tasks and environments.

Multisensory Integration: Maintaining the Perception of Synchrony

Abstract: We are rarely aware of differences in the arrival time of inputs to each of our senses. New research suggests that this is explained by a 'moveable window' for multisensory integration and by a 'temporal ventriloquism' effect.
