Lecture 14 Flashcards
what is the difference between systematic and humanistic research
systematic -> quantitative
humanistic -> qualititative
what does it mean for a song to go viral
-> how catchy a song is
-> how present it is in on social media
-> how it proliferates
Rosati, Bolker et al. said that songs in a electronica genre spreads similarly to what
what happens for transmission within a susceptible community (epidemic model)
define the recovery period
a period of time where the song loses its intense influence -> cooldown period
_______ is a type of auditory stimuli that present different frequencies to each ear
binaural beats
what can binaural beats produce
auditory illusions
define phase locking
a synchronization between the sound wave and pattern of hair cell firing
what structures of the brain is involved in phase locking
reticular activating system and inferior colliculus
what happens when you are watching a flashing light
at a certain and constant frequency, the neuronal firing will start matching this frequency information -> you will internalize a neural representation of the beat
binaural beats are thought to module both ______ and _____
neuronal firing and neural oscillations
alpha waves are associated with what
lower arousal and divergent thinking
-> drifting off to sleep
-> positive thinking
gamma waves are associated with what
-> memory recall
-> peak awareness
-> high level enhancement processing
true or false - alpha waves are prominent when writing a test
false - it is beta waves
true or false - theta waves are associated with REM sleep
true
a positive mood can enhance ______
creativity
what is suggested about people with schizophrenia and creativity
they have high levels of dopamine in certain parts of the brain and therefore demonstrate higher levels of creativity
which chemical in the brain is associated with promoting creative thinking
dopamine
define convergent thinking and which pathway is associated with this type of thinking
-> narrowing down a set of possibilities to find a single solution
-> frontal dopaminergic pathway
define divergent thinking and which pathway is associated with this type of thinking
-> generating a wide range of ideas from an open ended problem
-> striatal dopaminergic pathway
mental flexibility is supported by what pathway
striatal dopaminergic pathway
focused attention is supported by what pathway
frontal dopaminergic pathway
what is spontaneous eye blink rate used to measure
provide an estimate of the relative level of dopamine activity in the striatal dopaminergic pathway
eye blink rates is correlated with performance on what kind of tasks
divergent thinking tasks
Reedijk et al. tested the hypothesis that binaural beats can enhance creativity. what were the three stimuli used in this experiment
binaural beats representing alpha frequency, beta frequency and then a constant tone
which test measures convergent thinking
remote association test
which test measures divergent thinking
alternative/unusual uses test
what are the two main results of the experiment testing the hypothesis that binaural beats can enhance creativity (done by Reedijk)
-> low eye blink rates -> lower dopamine -> larger benefits for alpha binaural beats
-> high eye blink rates -> no benefits or perform worse
binaural beats enhanced performance in what type of thinking
divergent
why did participants with high eye blink rates perform worse in Reedijk’s experiment
if people already have high physiological arousal and close to their “sweet spot” -> pushes them farther down the Yerkes Dodson law -> detrimental to performance
what law did Reedijk et al.’s experiment base their interpretation of binaural beats and creativity off of
yerkes dodson law
