This Friday, at 1pm in room 306, we have an excruciatingly exciting confirmation talk...
Warrick Roseboom will be presenting a talk titled, " Temporal ventriloquism is relatively repulsive! "
An abstract follows:
It is well established that that different sensory events can become attracted toward one another across space and time. This can facilitate a sense of relatedness between cues arising from different sensory modalities. Humans, however, exist in cluttered environments, with many unrelated sensory events occurring in close spatial and temporal proximity. Accordingly, it is reasonable to conceive not only of integrating processes, which enhance a sense of relatedness across time, but also of temporally segregating processes. By simulating a temporally cluttered environment, we have shown that timing perception is shaped by interactions that can exaggerate the apparent temporal distance between discrete sensory events. We found that the point of perceptual synchrony for audio and visual events can be shifted away from the presence of additional, preceding or succeeding, audio or visual events. We establish that this effect is driven by a shift of audio-visual timing, rather than by a probabilistic analysis, and that it can enhance the sensitivity of timing judgments. These data suggest the existence of perceptual processes that segregate unrelated sensory events across time. These effects are likely to be integral to daily life, as humans exist in cluttered environments wherein many unrelated events occur in close temporal proximity.
