Sensation: Sensation is the initial process of detecting sensory information through our senses (e.g., seeing light waves or hearing sound waves). It is a physiological process.
Selective attention: Selective attention is the ability to focus on specific stimuli while filtering out irrelevant information. It allows us to pay attention to what is important and ignore distractions.
Gestalt principles: These are a set of principles that describe how our brain organizes sensory information into meaningful patterns and wholes. They include concepts like proximity, similarity, closure, and continuity.
