Perception

Perceptual Processing

• Bottom-Up Processing: Data-driven processing that begins with sensory input and builds up to final perception

• Top-Down Processing: Concept-driven processing guided by prior knowledge, expectations, and context

• Gestalt Principles: Principles describing how humans naturally organize visual elements into groups or unified wholes

• Feature Detection: The process of identifying specific elements or characteristics of visual stimuli

• Perceptual Constancy: The ability to perceive objects as unchanging despite variations in sensory input

Visual Perception

• Depth Perception: The ability to perceive the world in three dimensions and judge distances

• Binocular Cues: Depth cues that require both eyes, such as retinal disparity and convergence

• Monocular Cues: Depth cues available to each eye separately, such as linear perspective and relative size

• Face Recognition: The specialized ability to identify and distinguish individual faces

• Fusiform Face Area (FFA): Brain region specialized for face perception and recognition

• Recognition-by-Components (RBC): Theory proposing that objects are recognized by identifying their component geometric shapes

• Visual Search: The process of actively scanning the visual environment for particular objects or features
