Introspection (or internal perception) is the self-examination of one's conscious thoughts and feelings. In psychology, the process of introspection relies exclusively on the purposeful and rational self-observation of one's mental state; however, introspection is sometimes referenced in a spiritual context as the examination of one's soul. Introspection is closely related to the philosophical concept of human self-reflection, and is contrasted with external observation.
A view of the inside or interior; a looking inward; specifically, the act or process of self-examination, or inspection of one's own thoughts and feelings; the cognition which the mind has of its own acts and states; self-consciousness; reflection.
Prospective literally means "looking forward". It can also refer to an event that is likely or expected to happen in the future. For example, a prospective student is someone who is considering attending a school — typically a high school student who is seriously considering applying to a university, or who has already applied and been accepted, but not yet enrolled.
