Week 38 - Multisensory Integration Flashcards
Q: What type of cue do crossmodal correspondences fall under? Redundant cues, unrelated cues, or relative cues?
Parise (2016). Crossmodal Correspondences: Standing issues and experimental guidelines
A: Relative cues. Crossmodal correspondences are neither redundant nor completely unrelated cue dimensions. They have a relative connection, with further factors influencing the relationship
Q: Where do crossmodal correspondences come from?
Parise (2016). Crossmodal Correspondences: Standing issues and experimental guidelines
A: The exact origins are unknown, but a plausible hypothesis is that they reflect the statistical patterns and regularities in our environment
Q: What is a superadditive response?
Mather (2016), chapter 13: Multisensory processing in perception
A response to a combined stimulus which is greater than the sum of the responses to each stimulus presented separately
Q: What are event-related potentials (ERPs)?
Mather (2016), chapter 13: Multisensory processing in perception
Minute fluctuations in electrical potential in the brain caused by changes in sensory stimulation.
Q: What is the McGurk effect?
Mather (2016), chapter 13: Multisensory processing in perception
A perceptual interaction between vision and hearing in which visual observation of a speaker’s lips alters perception of speech sounds.
Q: What is cross-modal cueing?
Mather (2016), chapter 13: Multisensory processing in perception
Occurs when a cue stimulus presented in one sensory modality facilitates the detection or discrimination of a target stimulus presented in a different sensory modality.
Parise (2016), What are the three kinds of relationships that exist between sensory cues?
Redundant cues -> when two or more cues provide information about the same environmental property
Unrelated cues -> Cues about different and independent environmental properties.
Relative cues -> Neither redundant nor unrelated with further factors influencing the relationship
Parise (2016), In what way can perception be described as an inference problem?
We have to combine noisy sensory cues and prior knowledge in order to estimate the most likely state of the world
Q: Which three rules do the multimodal neurons obey?
Mather (2016), chapter 13: Multisensory processing in perception
Spatial coincidence, temporal coincidence, and inverse effectiveness
Q: On which parameter do individuals with synesthesia perform better than a non-synesthetic control group?
Mather (2016), chapter 13: Multisensory processing in perception
Memory (of word lists)
Q: What is synesthesia?
Mather (2016), chapter 13: Multisensory processing in perception
A multisensory phenomenon where stimulation in one sensory modality causes a sensory experience in another modality. An example could be letters evoking certain colors.
Q: What is the modular processing theory?
Mather (2016), chapter 13: Multisensory processing in perception
A theory of cognitive processing in which different functions such as vision, hearing, and memory are implemented in separate and independent processing modules.
Parise (2016), What are crossmodal correspondences?
Crossmodal Correspondences are compatibility effects between attributes or dimensions of a stimulus (i.e an object or event) in different sensory modalities (be the redundant or not)
Parise (2016), What are crossmodal correspondences?
Crossmodal Correspondences are compatibility effects between attributes or dimensions of a stimulus (i.e an object or event) in different sensory modalities (be the redundant or not)
Parise (2016), How do cultural and developmental factors influence crossmodal correspondences?
While many crossmodal correspondences appear universal, there is variation across cultures and developmental stages, suggesting some are influenced by learning and environment.
