My doctoral research primarily focused on how listeners perceive harmonic sounds -- sounds said to have 'pitch'. I found that listeners use different, context-dependent representations to make judgments about harmonic sounds. For example, representations used to remember harmonic sounds differ in format from those used for real-time discrimination of such sounds, and listeners likewise appear to rely on different representations in noisy versus quiet environments. I also conduct cross-cultural research. A recent project examined the universality of musical consonance and dissonance perception and preference in the Tsimane', an indigenous population in Bolivia.
