The study of the domain of
epistemology as it relates to or overlaps with
psychology.
While epistemology can be said to study questions relating to how or if we perceive "
reality", psycho-epistemology would focus on how human psychology processes or manages
perception. Phenomena such as
concept-formation,
introspection, and
habitual mental activities are in the domain of psycho-epistemology.
Epistemology could be described as studying the
interface of reality with the mind; psycho-epistemology would study what is done with the "reality" internally thereafter, and how these processes influence further perception.
Present notably in the philosophy of
Objectivism, probably predating that.
