👉 Nonperceptual refers to a phenomenon or behavior that is not perceived by an organism, such as a sound, smell, taste, touch, or vision. It can be difficult for humans to perceive these sensory inputs because they are often too subtle and weak to be detected directly. Nonperceptual behaviors are also known as emergent behaviors or learned behaviors, as they emerge from the interaction between the organism and its environment through a combination of sensory input and learning processes.
