Abstract

Musical expertise can lead to neural plasticity in specific cognitive
domains (e.g., in auditory music perception). However, not much is known
about whether the visual perception of simple musical symbols (e.g.,
notes) already differs between musicians and non-musicians. This was the
aim of the present study. Therefore, the Familiarity Effect (FE) – an
effect which occurs quite early during visual processing and which is
based on prior knowledge or expertise – was investigated. The FE
describes the phenomenon that it is easier to find an unfamiliar element
(e.g., a mirrored eighth note) in familiar elements (e.g., normally
oriented eighth notes) than to find a familiar element in a background
of unfamiliar elements. It was examined whether the strength of the FE
for eighth notes differs between note readers and non-note readers.
Furthermore, it was investigated at which component of the event-related
brain potential (ERP) the FE occurs. Stimuli that consisted of either
eighth notes or vertically mirrored eighth notes were presented to the
participants (28 note readers, 19 non-note readers). A target element
was embedded in half of the trials. Reaction times, sensitivity, and
three ERP components (the N1, N2p, and P3) were recorded. For both the
note readers and the non-note readers, strong FEs were found in the
behavioral data. However, no differences in the strength of the FE
between groups were found. Furthermore, for both groups, the FE was
found for the same ERP components (target-absent trials – N1 latency;
target-present trials – N2p latency, N2p amplitude, P3 amplitude). It is
concluded that the early visual perception of eighth note symbols does
not differ between note readers and non-note readers. However, future
research is needed to verify this for more complex musical stimuli and
for professional musicians.
