Outcome measures
Primary outcome
The main study parameter is the difference in BOLD signal in the experimental
conditions (participant drums with the experimenter and they are in sychrony)
compared to the condition where the experimenter drums out of phase (not in
sychrony) with the participant. The comparison of (1) to (2) will reveal
activation in brain regions that are responsible for creating music together
with someone in synchrony, hypothetically reward areas.
Secondary outcome
We will assign our volunteers randomly in 2 groups before scanning (double
blind). One group will have joint drumming with the experiment where the
experimenter is in phase (synchronized) with the participant 70% of the
experiment, whereas the experimenter will be in phase with the participants of
the other group only 30% of the experiment. After the scanning we will
investigate whether the joint drumming fosters prosocial behavior (altruism
especially) by comparing the behaviors of these 2 groups with a behavioral test
of pencil-dropping [van Baaren RB, Holland RW, Kawakami K, van Knippenberg A
(2004) Mimicry and prosocial behavior. Psychol Sci 15: 71-74.].
Background summary
The ability to create and enjoy music is a universal human trait and plays an
important role in the daily life of most cultures [1]. Merker proposes that in
musical contexts inter-individual synchronization can be observed among
dancers, performers and audience members. This type of synchrony is unique to
humans [2]. This study aims to investigate what is happening in the brain when
2 people synchronize their drums and create music in fMRI with a joint drumming
paradigm. Furthermore, it has been suggested that synchronous activity fosters
cooperation [3], it is possible that after such joint drumming experience might
create prosocial behaviors.

Study objective
We will investigate the neural correlates of sensorimotor synchronization of
two individuals in creating music in fMRI with a joint drumming paradigm where
the experimenter will drum with the participant in phase (with synchrony) in
the experimental blocks whereas in the control blocks the experimenter will
drum out of phase meaning drumming alone. We will compare these 2 conditions
where in the experimental condition the participants drum and hear the
synchronization of 2 drums and in the control conditions the participants drum
like in the experimental condition but hear another drum which is out of phase.
Thus in the control conditions participants will have amusical experience by
drumming alone while drumming the same way in the experimental condition.
Study design
The fMRI-study consists of two parts: a cardgame and joint drumming
The first part, the Cardgame, is a monetary task. The task of the participants
is to choose one card our of three in 2 seconds. S/he can choose a card by
pressing a button of an MR compatible button box. The participants are
instructed to earn as much money as possible during the experiment. At the end
of the experiment, the experimenter randomly chooses a session and actually
pays the earnings of the participant.
The second part, the joint drumming, the right handed participants will drum
together with the experimenter. The task of the participants is to drum in fMRI
by using the conventional button box. In order to keep all the participants at
the same beat and time they will be visually guided for the rhythm they should
play. The experimenter will drum, with the participants,too by using the same
button box. She will in the control room. This is an fMRI block design study
with 2 different blocks. In the experimental block, the experimenter will drum
with the participant simultanousely. Thus they will be in phase an will be
playing in synchrony. Whereas in the control blocks there will not be any
synchrony between the drummers because the experimenter will not hear the
participant's drum. The participant will be hearing both of them during both
blocks.
Study burden and risks
Subjects will be exposed to a magnetic field of 3 Tesla and rapidly alternating
magnet gradients and radio frequency fields. This field strength is used on a
routinely basis in fMRI and MRI research. So far, no side effects have been
described. On rare occasions, a peripheral nerve (abdomen) is stimulated by the
changing magnet gradients. This will cause an itching feeling, but it is not
harmful.
