The absolute pitch and the event related potentials:
The study of amplitudes, latencies, and distributions of P300 components.

ABSTRACT
The notion of reduced or absent P300 components for absolute pitch possessors has gained both supporting and challenging evidence in previous studies. Possible reasons for these inconsistent results include issues of screening process, task difficulty, and between-subjects variations in brain potentials. In this study, we investigated similarities and differences in P300 components between absolute and non-absolute pitch possessors while controlling the aforementioned three factors. Results confirmed that absolute pitch possessors elicit P300 components with smaller amplitudes relative to non-absolute pitch possessors in some tasks involving pitch discrimination. There were no differences in the distributions and latencies of P300 between two groups in all experimental conditions.

Key words: absolute pitch, event related potentials, P300 components, oddball paradigm
