Sensation and Perception

This AP Psychology study guide covers sensation and perception, focusing on how we process sensory information. Key topics include: the distinction between sensation and perception, bottom-up and top-down processing, thresholds (absolute, difference, and Weber's Law), signal detection theory, and sensory adaptation. The guide also examines the visual and auditory systems, including relevant anatomy, theories of color and sound processing, and other senses like taste, smell, touch, and balance. Finally, it explores perceptual influences such as perceptual sets, schemas, and context effects, and offers practice questions and exam tips.
