Lecture 7 Flashcards
true or false - all primates are able to reproduce rhythm
false - they are able to perceive rhythm but not reproduce it
what is an example of vocal learning mentioned in lecture
songbird copying another bird’s song
give examples of species that are not vocal learners but can perceive rhythm
sea lions and primates
what is the name of cells associated with a neural clock and its function
putaminal cells -> become active to represent distinct time intervals
what animal can time events very precisely
monkeys
where are putaminal cells located
dorsal striatum -> part of the basal ganglia
describe the odd ball paradigm
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
how can violations of the odd ball paradigm be measured
with EEGS and ERP components
what type of ERP components can be measured for odd ball paradigm
mismatch negativity response, N100 and N400
describe the differences between tapping in a reactionary way and anticipatory way
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
what was the potential failure of studies to find visual stimuli that have rhythms leading to beat perception
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
describe the possibility of what is happening when visual info does get perceived as having a beat (vision piggy back possibility)
visual information gets converted into auditory information -> relies on basic neurology driving beat perception
true or false - visually based stimuli produce stronger beat perception with auditory examples that follow the same beat
true
auditory examples that follow the same beat goes along with greater ______ activation
basal ganglia
what is the name of the independent structure involved in timing parameters that keep track and represents a beat based on any incoming data
supra-modal mechanism
