Definition
An involuntary response is a reflexive or automatic reaction that occurs without conscious control or effort. It is typically triggered by a specific stimulus.
A reflex is an involuntary response that occurs in response to a specific stimulus. It involves the activation of sensory neurons that send signals directly to motor neurons, bypassing the brain.
An unconditioned response is an involuntary reaction that occurs naturally in response to an unconditioned stimulus (UCS), without any prior learning.
Instinct: Instinct refers to innate behaviors that are biologically programmed and do not require any learning. These behaviors are present from birth and are essential for survival and adaptation.
