lecture 10 Flashcards
nonlocal dependancies
dependencies that expand over a longer period of time, instead of just adjacent notes
later/earlier replanning
Violation of expectancy classical pianists vs jazz pianists
the jazz pianists replan earlier more versatile and could throw down something that sounds right to replan than the inflexible classical pianists who are used to
ERP
ERAN
- differences are seen in musicians specializing in different genres
Gun and Koelsch (2016) experiement with ERAN latency
- manipulated whether or not participants were expecting a brief sequence of chords to end on a syntactically irregular chord
- cueing participants about the irregular chord affected the latency of the ERAN (thought the amplitude was relatively unaffected)
- noticed the apparent (modest) effect of musicianship
abnormal ERANS
- it emerges childre
binaural beats
auditory stimuli that present slightly different frequencies to each ear
how do they create
phase locking
- a synchronization between the sound wave and pattern of hair cell firing
- firing at the peak and stop at the valley/trough
how do neural oscillations play a role in binaural beats?
OBSERVED BY EEG
- beta-band activity: correlated with beat/rhythm perception, memories and arousal
- gamma: intentional or controlled top-down mediated, retrieval of memories
- alpha: lower arousal and divergent (creative) thinking, sleep
how can we intrain the brain to particular rhythms?
evidence for dopamine role in creativity
- promotes creative thinking
- positive mood can enhance creativity
- schizophrenics w high levels of dopamine in parts of the brain demonstrate higher creativity
- people feel more creative under the influence of various substances that alter dopamine function
