Rely on sensory systems to provide information; prioritize important info while some get ignored: sensation detection of stimuli by a sensory receptor (objective) Bottom-up processing relies on the properties of the stimulus (shading, patterns: data-driven approach perception directs cognition leads to decisions/ behavior, perception combination of processing the sensation aspects and past experiences (subjective) How sensory information is organized, interpreted, and experienced.
