Q

describe the odd ball paradigm

A

asses the neural response to violations of our expectations
-> you present stimuli that are typically the same but have a property in common that can differ -> A,A,A,A -> A,B,A,A -> if successfully internalized, you can continue to tap where the beat should be

Q

describe the differences between tapping in a reactionary way and anticipatory way

A

tapping in a anticipatory way -> building an internal model that involved expectations for what would come back

tapping in a reactionary way -> relies on direct sensory perception

Q

what was the potential failure of studies to find visual stimuli that have rhythms leading to beat perception

A

because of unnatural stimuli due to ecological validity
-> if you are not using stimuli that is representative of stuff people interact with in the real world, then you cannot generalize

Q

describe the possibility of what is happening when visual info does get perceived as having a beat (vision piggy back possibility)

A

visual information gets converted into auditory information -> relies on basic neurology driving beat perception

17
Q

what are 4 factors involved in the ability to perceive/reproduce a rhythm

A

musical training, short term memory, dopaminergic function and regularity detection
