Does music affect the time it takes for a child to put together a puzzle?

I could not find a study directly relating between music and puzzles.
It has long been known that music does increase your iq. So from that
you can logivally assume that music will help you with puzzles.

A study at the University of Toronto hypothesized the cause-effect
relationship: studying music enhances a child?s IQ. The study involved
advertising for volunteers and setting up two control groups, one
whose members received drama lessons and another group whose members
were offered no lessons. The group receiving music lessons were split
between keyboard and voice. The children were all six years old.

The study confirmed the hypothesis. The students taking music lessons
had an increase in IQ while the control groups did not. The research
also showed that while there was no effect on the IQ of the students
taking drama lessons, the kids in that control group did exhibit an
increase of social skills higher than any other group in the study.

bethinvero-ga,
     A number of studies have looked at the effect of music on a
variety of motor and cognitive tasks.   A marginal effect can be found
in some of the studies.  Like the other poster, I've not seen a
specific study for puzzles but a group of studies based on motor and
cognitive tasks would cover many of the skills used in assembling a
puzzle.  As a science fair project, this should be a good project to
implement with an adult advisor to help you with the controls you
would need.  I'm
attaching a few links that can guide you in what to look for in
setting up your study.  A couple are term papers from students like
yourself.

Read an "THE EFFECTS OF MUSIC ON THE MIND" written by Kristian David
Olson in 1996 at http://www.bobjanuary.com/musicmnd.htm

your question "Does music affect the time it takes for a child to put
together a puzzle?"
To clarify what you have asked, I break it down like this

Puzzle (in the question context) - Any puzzle
Child (in the question context) - any human individual before the
teenage era capable of solving and/or trying to solve any puzzle

I got my toddler and my nephew, aged 3 and 4 to work on the rubik's
cube. Marked their progress for ten minutes time frame without music.
Marked their progress for ten minutes with music from bbc balamory.

Result was that music distracted them from doing anything to the cube.

Result was different when I used eminem as they left the scene of the
music and the rubik's cube :-)
