Main point:

A virtual history lesson with or without instrumental background music was presented to the participants. Two differnet display systems: Reality Center, 3-monitor system. n=48 (mean age 22.7). 3-monitor group remembered more facts than Reality Center group (both ‘music’ and ‘no music’ conditions). Reality Center group remembered more facts when background music was played.

In my opinion the groups were too small to use so many conditions. Let’s take one thing at the time or increase the samples.
