Music is a perfect domain for studying cognitive representations due to its dominant role in our daily experiences. Whether you are trying to sing back a melody, decide if you like a new musical chord, or figure out if what you just heard was a song, your mind is applying complex processing to make sense of this rich sensory input. I am very interested in characterizing such processes and the cognitive representations that support them by leveraging large-scale adaptive experiments and computational models. Some of the projects that I work on in this domain include: (i) Psychoacoustic theories of consonance (Marjieh et al., 2024), (ii) Musical pitch representations (Marjieh et al., 2024), (iii) Rational accounts of the speech-to-song illusion (Marjieh et al., 2024), and (iv) Cultural evolution of sung melodies (Marjieh et al., 2025).
