Final answer:
Emotions are subjective experiences influenced by cognitive appraisal and conscious thought, whereas instincts are unlearned, innate behaviors that occur automatically in response to specific stimuli, involving the movement and actions related to survival.
Step-by-step explanation:
The primary distinction between emotions and instincts lies in their origin and function. Emotions are complex psychological states that involve an individual's subjective experience, cognitive appraisal, and physiological responses to stimuli. These can be external, such as something we see or hear, or internal, such as our thoughts. Emotions often involve conscious awareness and can be influenced by our perceptions and reasoning.
On the other hand, instincts are unlearned knowledge that manifest as complex patterns of behavior, which are largely involuntary responses to certain stimuli. These behaviors are considered innate and are more prevalent in animals with lower levels of intelligence. Instincts involve the whole organism and relate to survival and reproduction, such as migration, mating rituals, and reflex actions.
In essence, emotions can be considered more subjective and can be shaped by personal experience and conscious thought, whereas instincts are preprogrammed behaviors that drive an organism to react in certain ways for survival without the need for prior learning or experience.
