Multi-Modal perception

Question 1

Bouncing balls illusion

Answer 1

The tendency to perceive two circles as bouncing off each other if the moment of their contact is accompanied by an auditory stimulus.

Question 2

Crossmodal phenomena

Answer 2

Effects that concern the influence of the perception of one sensory modality on the perception of another.

Question 3

Crossmodal receptive field

Answer 3

A receptive field that can be stimulated by a stimulus from more than one sensory modality.

Question 4

Crossmodal stimulus

Answer 4

A stimulus with components in multiple sensory modalties that interact with each other.

Question 5

Double flash illusion

Answer 5

The false perception of two visual flashes when a single flash is accompanied by two auditory beeps.

Question 6

Integrated

Answer 6

The process by which the perceptual system combines information arising from more than one modality.

Question 7

McGurk effect

Answer 7

An effect in which conflicting visual and auditory components of a speech stimulus result in an illusory percept.

Question 8

Multimodal

Answer 8

Of or pertaining to multiple sensory modalities.

Question 9

Multimodal perception

Answer 9

The effects that concurrent stimulation in more than one sensory modality has on the perception of events and objects in the world.

Question 10

Multimodal phenomena

Answer 10

Effects that concern the binding of inputs from multiple sensory modalities.

Question 11

Multisensory convergence zones

Answer 11

Regions in the brain that receive input from multiple unimodal areas processing different sensory modalities.

Question 12

Multisensory enhancement

Answer 12

See “superadditive effect of multisensory integration.”

Question 13

Primary auditory cortex

Answer 13

A region of the cortex devoted to the processing of simple auditory information.

Question 14

Primary visual cortex

Answer 14

A region of the cortex devoted to the processing of simple visual information.

Question 15

Principle of Inverse Effectiveness

Answer 15

The finding that, in general, for a multimodal stimulus, if the response to each unimodal component (on its own) is weak, then the opportunity for multisensory enhancement is very large. However, if one component—by itself—is sufficient to evoke a strong response, then the effect on the response gained by simultaneously processing the other components of the stimulus will be relatively small.

Question 16

Receptive field

Answer 16

The portion of the world to which a neuron will respond if an appropriate stimulus is present there.

Question 17

Rubber hand illusion

Answer 17

The false perception of a fake hand as belonging to a perceiver, due to multimodal sensory information.

Question 18

Sensory modalities

Answer 18

A type of sense; for example, vision or audition.

Question 19

Spatial principle of multisensory integration

Answer 19

The finding that the superadditive effects of multisensory integration are observed when the sources of stimulation are spatially related to one another.

Question 20

Superadditive effect of multisensory integration

Answer 20

The finding that responses to multimodal stimuli are typically greater than the sum of the independent responses to each unimodal component if it were presented on its own.

Question 21

Unimodal

Answer 21

Of or pertaining to a single sensory modality.

Question 22

Unimodal components

Answer 22

The parts of a stimulus relevant to one sensory modality at a time.

Question 23

Unimodal cortex

Answer 23

A region of the brain devoted to the processing of information from a single sensory modality.
