What distinguishes multimodal perception from unimodal perception?
What distinguishes multimodal perception from unimodal perception?
- Multimodal perception is processed in the primary sensory cortex, while unimodal perception is processed in higher-order association areas.

Study Notes
- Multi-modal Perception is when multiple senses are being used simultaneously
Our Sensory World
- Unimodal processing is a single sensory or perceptual process
- Multimodal processing is combining various modalities like vision, audition, touch, proprioception
- Perceptions are frequently multimodal
Attributes of Stimuli
- Stimuli attributes include modality, intensity, location, and duration
- Perception of stimuli in different modalities sharing location, timing, and duration can result in emergent properties
Unimodal Processing
- The cortex has primary receiving areas for distinct sensory inputs
- These areas process simple, low-level stimulus features
- Area V1, the primary visual area, is the first stage of cortical processing of visual information like orientation, movement and edges
The Super-Additive Effect
- Multisensory input can improve perception of ambiguous unisensory information
- Visual and auditory information together can improve perception more than the sum of their individual inputs with the whole being greater than the sum of its parts
Principle of Inverse Effectiveness
- As responsiveness to individual sensory stimuli decreases, the strength of multisensory integration increases
Multisensory Convergence Zones
- These convergence zones are brain areas where input from more than one sensory modality converges
- Multisensory convergence zones combine this input to create a unified perceptual experience
- The superior temporal sulcus has individual cells that respond to inputs from vision and speech
- The superior colliculus receives inputs from vision and audition centers, and is involved in reflexive head movements to orient toward stimuli
Multisensory Areas of the Neocortex
- Traditionally the cortex was understood to have select multisensory areas
- More recent anatomical and electrophysiological data has shown the cortex to be multisensory
The Binding Problem
- The binding problem is the challenge of understanding how the brain integrates sensory features like color, shape, and location
- These features are processed in different brain areas to create a unified perception of an object or event
Effects Highlighting Multi-Modal Perception
- The McGurk Effect is the phenomena where visual stimuli impacts the perception of speech
- The Rubber Hand Illusion is where combined vision and tactile sensation can create an illusion of body ownership of a rubber hand
- The Bouncing Balls Illusion joins vision and audition to create an illusion of collision before or after collision occurs
