The present study reexamined the mood-mediation hypothesis for explaining
background-music-dependent effects in free recall. Experiments 1 and 2
respectively examined tempo- and tonality-dependent effects in free recall, which
had been used as evidence for the mood-mediation hypothesis. In Experiments 1
and 2, undergraduates (n = 75 per experiment) incidentally learned a list of 20
unrelated words presented one by one at a rate of 5 s per word and then received
a 30-s delayed oral free-recall test. Throughout the study and test sessions, a piece
of music was played. At the time of test, one third of the participants received the
same piece of music with the same tempo or tonality as at study, one third heard a
different piece with the same tempo or tonality, and one third heard a different
piece with a different tempo or tonality. Note that the condition of the same piece
with a different tempo or tonality was excluded. Furthermore, the number of
sampled pieces of background music was increased compared with previous
studies. The results showed neither tempo- nor tonality-dependent effects, but only
a background-music-dependent effect. Experiment 3 (n = 40) compared the effects
of background music with a verbal association task and focal music (only listening
to musical selections) on the participants’ moods. The results showed that both the
music tempo and tonality influenced the corresponding mood dimensions (arousal
and pleasantness). These results are taken as evidence against the mood-mediation
hypothesis. Theoretical implications are discussed.
