š§ FLASHCARD DECK ā MALLIK & RUSSO (2022) Anxiety RCT
(Method + concise findings)
Q: What was the purpose of Mallik & Russo (2022)?
A: To test whether personalized music and auditory beat stimulation (ABS) reduce anxiety compared to control conditions.
Q: What was the study design?
A: An online randomized controlled trial using the LUCID music platform.
Q: Who were the participants?
A: 163 adults currently taking anxiolytics, categorized into moderate and high trait-anxiety groups.
Q: What were the experimental conditions?
A:
music + ABS
music alone
ABS alone
pink noise (control)
Q: What were the main outcome measures?
A: Pre/post somatic anxiety, cognitive anxiety, and positive/negative affect, plus personality and music preference.
Q: What did music + ABS do for moderate-anxiety participants?
A: It produced the largest reduction in cognitive anxiety and improved positive affect more than the control.
Q: How did music alone compare for moderate-anxiety participants?
A: It reduced somatic anxiety more effectively than pink noise.
Q: What happened with high trait-anxiety participants?
A: Music alone was most effective; ABS added no extra benefit.
Q: What is the practical takeaway of this RCT?
A: Music-based interventions lower anxiety, but music + ABS works best for moderate anxiety, while music alone works best for high-trait anxiety.
šµ FLASHCARD DECK ā WEEK 10 LECTURE: MUSIC AS MEDICINE
(Method = type of evidence, not a single experiment)
Q: What type of evidence does the Week 10 lecture summarize?
A: A collection of neuroscience, clinical trials, psychophysiology, genetics, and music-therapy research ā not one study.
Q: How does music activate the brain?
A: It stimulates the mesolimbic dopamine system, the same reward network triggered by food, sex, and drugs of abuse.
Q: What role does prediction play in musical pleasure?
A: The brain constantly predicts incoming sounds; small violations in expectation generate reward (prediction error).
Q: Why are musical chills important?
A: They occur at peak reward moments when auditory, emotional, and reward circuits synchronize.
Q: How does TMS (brain stimulation) affect musical reward?
A:
Excitatory TMS ā increases pleasure
Inhibitory TMS ā decreases pleasure
This demonstrates a causal link between frontalāstriatal pathways and musical enjoyment.
Q: What tool measures individual differences in musical reward?
A: The Barcelona Music Reward Questionnaire (BMRQ).
Q: What does research show about heritability of musical reward?
A: Musical reward sensitivity is partly genetic, independent from general reward sensitivity.
Q: Why does familiarity increase musical reward?
A: Repeated exposure builds predictive accuracy; liking grows until it peaks (inverted-U curve) and then declines.
Q: How do personal preferences shape reward?
A: Preferred music generates stronger emotional, auditory, and reward-network activation, especially in highly reward-sensitive people.
Q: What are historical examples of therapeutic music use?
A: From shamanic rituals to Gregorian chants to modern music therapy, music has long been used to regulate emotion and behavior.
Q: What modern technologies enhance therapeutic music?
A:
AI music personalization
Iso-principle matching
Biometric feedback loops
Auditory beat stimulation (ABS)
Q: What is the Iso-Principle?
A: Match the personās current mood first ā then shift the music to guide them toward a desired emotional state.
Q: What clinical areas show strong evidence for music interventions?
A:
Movement rehabilitation (e.g., Parkinsonās, stroke)
Anxiety reduction
Social bonding
Dementia agitation reduction
Q: What does the dementia research suggest?
A: Personalized music interventions reduce agitation and improve emotional regulation in mild-to-moderate dementia.
Q: What is the overall conclusion from Week 10?
A: Musicās therapeutic power comes from its ability to modulate attention, emotion, prediction, and physiology, especially when personalized.
