Question 1

Intermodal perception takes up to one month to accurately assess in infants.

Accepted Answer

Intermodal perception is the ability to integrate information from multiple sensory modalities (such as sight and sound) to form a coherent perceptual experience. Research has found that infants as young as 2-4 months old show evidence of intermodal perception, suggesting that it develops earlier than previously thought. Specifically, infants can match auditory and visual stimuli, and can detect when the two are not aligned. While the exact timeline for accuracy in intermodal perception may vary depending on the study, it generally does not take up to one month for infants to develop this ability.

Question 2

Infants expect vision, auditory, and tactile information to occur together.

Accepted Answer

This is true. Infants have been shown to expect multisensory integration from a very early age, and are able to detect when visual, auditory, and tactile information are not occurring together. This ability is important for the development of perception and cognition.
