Page 2: Sensory Processing and Perception

This page delves into sensory adaptation and various theories of perception, including the opponent-process theory and photoreceptor function. It explains how our senses adjust to stimuli and process visual information.

Definition: Opponent process theory explains how emotions and sensory experiences are processed in opposing pairs.

Example: Motion parallax can be experienced while driving, where nearby objects appear to move faster than distant ones.

Vocabulary: Photoreceptors are specialized cells in the eye that respond to light, including both rods and cones.

Highlight: The absolute threshold represents the minimum amount of stimulus energy needed for detection by human senses.

Page 1: Visual Processing Fundamentals

This page introduces fundamental concepts of visual processing, including the young-helmholtz trichromatic theory and various depth perception cues. The trichromatic theory explains how humans perceive color through three types of cone cells, while depth perception is facilitated through multiple visual cues.

Definition: Trichromatic theory of color vision states that humans perceive colors through three types of cone cells sensitive to red, blue, and green light.

Example: Relative height monocular cue example can be observed when looking at a landscape painting where distant mountains appear higher in the visual field than nearby trees.

Highlight: Color blindness is predominantly found in males and results from missing or defective cone cells.

Vocabulary: Interposition refers to the overlapping of objects in the visual field, serving as a depth cue.
