Alejandro Tabas: How do background differences influence pitch perception?

Researcher: Alejandro Tabas

People from different cultural backgrounds have been observed to show different       performance in pitch perception tasks. More specifically, people with a tonal mother tongue and musicians are able to distinguish more subtle pitch variations than     non-musician Western people.

While pitch perception is believed to be implemented in lower layers, these kind of cultural differences should be implemented in higher levels of the cortex. Therefore, some kind of top-down modulation has to be responsible for this effect.

In our project, we will try to propose a biologically sound model accounting for this effect, using                          electro-physiologic recordings to validate our theory.
