Let's dive into these terms from a psychological perspective:
Objective:
Definition: Pertaining to or signifying something that is independent of the mind and exists in the external world; based on observable phenomena, uninfluenced by emotions or personal prejudices.
Example in Psychology: A clinician using a standardized test to measure a client's level of depression. This is objective because the test's results are based on a set standard and aren't swayed by the clinician's personal feelings about the client.
Subjective:
Definition: Pertaining to or signifying the operations of the mind; based on or influenced by personal feelings, tastes, or opinions.
Example in Psychology: A patient's self-report about how they feel on any given day. This is subjective because it's based on the individual's personal experience and feelings, which might not be observable or verifiable by others.
Perspective:
Definition: A particular attitude or way of viewing something; a point of view.
Example in Psychology: Different psychologists might adopt different perspectives to understand human behavior, such as the cognitive perspective (focusing on mental processes) or the behavioral perspective (focusing on observable behaviors).
Perception:
Definition: The process by which people select, organize, interpret, and respond to information from the external world; it's how we make sense of what we see, hear, taste, touch, and smell.
Example in Psychology: The Müller-Lyer illusion, where two lines of the same length appear to be of different lengths because of the angle of the arrows at their ends. This illusion highlights that our perception (seeing one line as longer than the other) doesn’t always match objective reality (both lines are the same length).
Aperception:
Definition: Aperception is the process by which new experiences are assimilated to and transformed by the residuum of past experience of an individual to form a new whole. In simpler terms, it refers to how current perceptions are influenced or shaped by one's previous experiences or knowledge.
The term has historical significance in both philosophy and psychology:
Philosophical Usage: German philosopher Leibniz introduced the term "apperception" to refer to conscious perception, distinguishing it from mere unconscious reception of sensory stimuli. For Leibniz, apperception is the reflective consciousness of one's own mental states.
Psychological Usage: In the realm of psychology, the concept was used extensively by Wilhelm Wundt, who is often considered the founder of experimental psychology. For Wundt, apperceptive processes involve the active, conscious manipulation of the contents of consciousness.
Example in Psychology: Consider a situation where a person sees a snake for the first time after having heard many stories about how dangerous they can be. Their immediate perception might not just be "it's a snake," but could be infused with fear, caution, and a heightened sense of awareness due to their pre-existing knowledge about snakes. This influenced perception, shaped by prior knowledge, is a result of the process of aperception. This concept emphasizes the active role of previous experiences and knowledge in shaping our current perceptions.
