Music Perception & Cognition Flashcards
(9 cards)
How did string instrument players differ from non-musicians?
Increased neuroplasticity / higher brain activity for musicians.
Where is the primary auditory cortex?
Temporal lobe.
What are predictive processes essential in?
Perception & action, influenced by selective attention.
What is predictive coding (PC)?
Framework of backward predictions passed down cortical hierarchies to resolve prediction errors occurring at lower levels (sensory info not matching a prediction)
Prediction errors ascend to lead to better predictions (both bottom-up and top-down processes)
What influences our predictions?
Musical groove, which is driven by a musical pulse that calls for synchronisation of movement.
Syncopations –> wanting to move –> groove
How does selective attention influence our musical groove?
We attend to specific auditory consequences of our internal interpretation of music, suppressing overt action.
What are oddball events?
Events that interrupt a repeated pattern / sequence.
What is mismatch negativity?
A brain event-related potential (ERP) that occurs around 100 to 250 milliseconds following the event that triggers it (usually oddballs)
What type of deviants does MMN respond to?
- Sound frequency
- Loudness intensity
- Duration
- Sound location
- Diff speech sounds
