Principles of Sensation

This study guide covers sensation and perception, including the difference between bottom-up and top-down processing. It explores sensory adaptation, habituation, and the types of senses (energy, chemical, and body position). Gestalt principles of organization (proximity, continuity, closure, figure-ground) are discussed. The guide also explains sensory transduction, absolute and difference thresholds, Weber's Law, and signal detection theory. Finally, it provides practice questions and exam tips.
