Lecture 31 Flashcards
what does musical therapy improve in Parkinson’s patients?
motor rehab
what did walking along with rhythmic audio cue improve?
walking behaviors
- reduced freezing
- improved gait velocity
- improved stride length
- cadence
- number of steps per min
did improvements remain after removing the audio cues?
yes there is certain durability of such effects
what are the motor-related benefits derived from?
providing a framework that provides temporal expectations that make predicting/executing the next steps in sequences easier
->neural entrainment
what do some of the mechanisms related to motor-rehab do?
helps regulate or stabilize impaired sensorimotor networks through compensatory activity in other networks that may be less compensated
what kind of implants can be used to replace the functionality accomplished by hair cells in cochlea?
cochlear implants
-> transduce pressure waves
using a cochlear implant provides what kind of hearing?
- hearing is less sensitive than before the hair cells got damaged
- processing spectrally complex stimuli can be difficult
spectrally complex stimuli is common is what kind of representations?
musical
what are some challenges associated with using CI patients in experiments?
- heterogeneity
- users are unable to participate in fMRI experiments -> need to use EEG to see any potential changes accompanied with training
congenitally deaf CI children participating in computerized music training improved in what type of performance?
melodic contour identification
Peterson et al. reported a change in ________ in response to variations in _____, ______, ________, in CI group following musical training
MMN
timbre
intensity
rhythm
Peterson et al., found what kind of effects from musical representations to sounds of speech?
transfer
children with 1.5-4 yrs of musical training outperformed a CI control group in tests of __________ and ___________
phonetic discrimination
auditory scene analysis
why do people with autism have a higher probability of having absolute pitch?
they may be paying attention to things that the general population does not pay attention to during early development allowing for practice
what does Gaver’s ecological theory of auditory perception emphasize?
processing of the fxn of sounds over their acoustic properties
give an example of Gaver’s ecological theory of auditory perception?
sound of a bus on busy city street will generally come to be more closely associated with it’s fxn than the timbre of engine
