Attention:The mental process of focusing awareness on specific stimuli. It plays a crucial role in detecting changes because if your attention is elsewhere, you may miss important alterations in sound.
Perceptual set: A predisposition to perceive things in a certain way based on previous experiences or expectations. Your perceptual set can influence how quickly and accurately you detect changes in music tracks.
