• Rauscher, Shaw, Ky, 1993:
• effects of listening Mozart
Sonata for Two Pianos in D
Major (K.448)
• on adult spatial capacities
• 8-9 points increase on IQ scale
• Short term effects
• Failed to be confirmed by other
laboratories
The central finding of the present paper
however, is certainly the noticeably higher
overall effect in studies performed by
Rauscher and colleagues than in studies
performed by other researchers, indicating
systematically moderating effects of lab
affiliation. On the whole, there is little
evidence left for a specific, performanceenhancing Mozart effect. (Pietschnig, et
al, 2010)
Mr. Miller, a Democrat, proposed as part of his $12.5 billion
state budget on Tuesday to spend $105,000 to make music
available to each of the approximately 100,000 children born
in Georgia each year.
‘‘No one questions that listening to music at a very early age
affects the spatial, temporal reasoning that underlies math
and engineering and even chess,'' the Governor said today.
''Having that infant listen to soothing music helps those
trillions of brain connections to develop.’
Origins of neuromyths

1. Distortions of scientific facts, undue
simplifications
2. Offspring of scientific hypotheses that
have been held true for a while, and
then abandoned because of the
emergence of new evidence
3. Use of scientific jargon with no
scientific reference, even loose
Specialization of the hemispheres

“Equilibration of the
hemisperes”, as in Brain Gym

There are many hypotheses in science, which
are wrong, that’s perfectly on right, that’s the
opportunity of finding out what’s right.
Science is a self-correcting process. For being
accepted, ideas must survive the most
rigorous standards of evidence and scrutiny.

Expert images & the polaroid effect
The neuroscience studies that we see in the news are regularly accompanied by
pictures of the brain, showing colorfully "glowing" bits of neural tissue.
As humans, we are highly visual creatures, accustomed to relying on the fact that
what we see is actually happening in the world.
Looking at these brain pictures often gives us the feeling that we have a window into
the brain and that we can actually see what the brain is doing. But this is simply not
accurate. An fMRI scanner is not a window or even a microscope; the output that it
provides is not really a picture of the brain, at least not in the way that the output of a
camera is a picture of a face. (Weisberg 2008)

• Proliferation of neuro-labels

• Soothing function
• Optimistic cognitive illusions
• Confirmation bias
• Correlation/causation illusions
