The eye adjusting its lens shape to focus light on the retina for clear vision at different distances

Rods: Low-light, no color; Cones: Bright light, color vision

Area on retina with highest visual acuity, densely packed with cones, sharp central vision.

Light wave to neural impulse, a chemical process in photoreceptors (rods and cones).

No photoreceptors where optic nerve leaves the eye, creating a visual gap.

Cones that respond to short wavelengths of light (~420nm), mainly blue light

Brain combines signals from different cone types to perceive a wider range of colors.

The brain's response to overstimulation of color receptors creates a complementary color.

One object overlapping another, making the obscured object seem further away.

Objects higher in the visual field appear further away, while lower objects appear closer.

Difference in the images seen by each eye, providing depth perception

Failure to notice visual changes in a scene due to distraction or interruptions.

Failure to notice a visual stimulus when your attention is diverted to something else.

Photoreceptor cells responding to medium wavelengths, primarily green light.

Photoreceptor cells sensitive to long wavelengths, primarily red light.

Brain combining cone inputs to perceive a wide range of colors.

Different wavelengths stimulating cones in different combinations, creating perceived colors like yellow.

Visual system processing colors in opposing pairs (red-green, blue-yellow, black-white).

Visual illusion seeing an opposing color after staring at a colored object.

Neurons responding to specific visual features (orientation, movement, length).

Maintaining a stable object perception despite changes in sensory input (distance, angle, light).

We tend to perceive things as organized wholes, not parts.

We see complex shapes as simplest forms possible.

Simple, closure, continuity, similarity, proximity, common fate for better organization.

Differentiating object (figure) from background (ground).

Using one eye to perceive depth (e.g., relative size, linear perspective).

Smaller objects seem further away, if same size.

Parallel lines seem to converge, creating distance.

Eye adjusting lens shape to focus light on retina for clear vision at varying distances.

Rods: Low light, no color; Cones: Bright light, color vision

Area on retina with sharpest vision, lots of cones.

Converting light waves into neural impulses in the eye.

Area on retina where optic nerve leaves eye, no photoreceptors.

Cones that respond to blue light wavelengths.

Brain combines cone signals to see a wider range of colors.

Brain's response to overstimulation of color receptors creates an opposing color.

Three types of cones that respond to specific wavelengths: red (L-cones), green (M-cones), and blue (S-cones).

Light hits photoreceptors (rods & cones) causing chemical changes, that trigger nerve impulses.

Photoreceptors sensitive to medium wavelengths, primarily green light.

Photoreceptors stimulated by long wavelengths, primarily red light.

Our brain combines cone signals to perceive a wide range of colors.

Different wavelengths stimulate cones in different combinations.

Color processing through opposing pairs (red-green, blue-yellow, black-white).

Visual illusion of opposite color after staring at a color.

Neurons that respond to specific visual characteristics.

Seeing objects as stable despite changes in environment.

Smaller objects appear farther away, if objects are known to be similar sizes.

Parallel lines converging creates depth in visual scenes.

One object overlapping another, making the obscured object seem further away.

Objects higher in the visual field appear further away, while lower objects appear closer.

Difference in the images seen by each eye, providing depth perception.

Failure to notice visual changes in a scene due to distraction or interruptions.

Failure to notice a visual stimulus when your attention is diverted to something else.

The brain's ability to perceive the 3-dimensional world from 2-dimensional images

Objects closer to us create more significant differences in the images in each eye.

Each eye captures a slightly different viewpoint of the same scene.

The larger the difference between the images, the closer the object is.

The perception of depth from the brain combining the images from two eyes.
