An early perceptual locus of absolute pitch.

Absolute pitch (AP) refers to the naming of musical tone without external reference. The influential two-component model states that AP is limited by the late-emerging pitch labeling process only and not the earlier perceptual and memory processes. Over the years, however, support for this model at the neural level has been mixed with various methodological limitations.

Cross-modal association between vowels and colours: A cross-linguistic perspective.

Previous studies showed similar mappings between sounds and colours for synaesthetes and non-synaesthetes alike, and proposed that common mechanisms underlie such cross-modal association. The findings between vowels and colours, and between pitch and lightness, were investigated separately, and it was also unknown how language background would influence such association. The present study investigated the cross-modal association between sounds (vowels and pitch) and colours in a tone language using three groups of non-synaesthetes: Cantonese (native), Mandarin (foreign, tonal), and English (foreign, non-tonal).
