Describe how the brain and the eye process visual information

2. The Eye

3. THE STRUCTURE OF THE EYE

4. Cornea = outer covering of the eye.

5. Pupil = the adjustable opening in the center of the eye through which light enters.

6. The iris dilates/constricts in response to changing light intensity
Iris = a ring of muscle tissue that forms the colored portion of the eye around the pupil and controls the size of the pupil opening.

7. Lens = the transparent structure behind the pupil that changes shape to help focus images on the retina.

8. Retina = lines the back of the eye consists of rods and cones (we will talk about this later)

9. Blind Spot = the point at which the optic nerve leaves the eye, creating a “blind” spot because no receptor cells are located there.

10. Fovea = where the cones in the eyes cluster.

11. Optic Nerve = the nerve that carries neural impulses from the eye to the brain.

12. The Retina

13. THE RETINA Rods = processes grayscale and helps us with overall shape.
Cones = processes fine color and detail

14. VISUAL INFORMATION PROCESSING

15. How they all come together to form an image?
Parallel Processing
Breaking down an image for your brain to process the information. Research shows each step is sent to different parts of the brain.

21. ESP Research
Main criticism: many studies completed cannot be replicated
Daryl Bem (skeptic) asked people self-reporting ESP when participants to predict erotic scenes in movies. 53.1% did (better than the 50% average).
Criticism: follow up studies have not shown the same results.
