BACKGROUND: The aim of the present study was to investigate how auditory background interacts with learning and memory. Both facilitatory (e.g., "Mozart effect") and interfering effects of background have been reported, depending on the type of auditory stimulation and of concurrent cognitive tasks.
METHOD: Here we recorded event related potentials (ERPs) during face encoding followed by an old/new memory test to investigate the effect of listening to classical music (Čajkovskij, dramatic), environmental sounds (rain) or silence on learning. Participants were 15 healthy non-musician university students. Almost 400 (previously unknown) faces of women and men of various age were presented.
RESULTS: Listening to music during study led to a better encoding of faces as indexed by an increased Anterior Negativity. The FN400 response recorded during the memory test showed a gradient in its amplitude reflecting face familiarity. FN400 was larger to new than old faces, and to faces studied during rain sound listening and silence than music listening.
CONCLUSION: The results indicate that listening to music enhances memory recollection of faces by merging with visual information. A swLORETA analysis showed the main involvement of Superior Temporal Gyrus (STG) and medial frontal gyrus in the integration of audio-visual information.
