5.3 Vision — Your Brain Is Editing What You See | Psychology 2e
After this lesson you will be able to…
- Understand how the brain actively constructs visual reality through filtering and rendering.
- Learn how pupil size is influenced by both light levels and emotional states.
- Differentiate the roles of cones and rods in vision, including their light sensitivity and resolution.
- Understand the process of visual adaptation and the cause of night blindness.
- Explain how the brain compensates for the eye's physical blind spot.
- Understand the contralateral routing of visual information at the optic chiasm and its evolutionary purpose.
- Identify the 'what' and 'where' pathways in the visual cortex and their functions.
- Explore the ethical tension between animal suffering and scientific discovery in neuroscience.
- Understand the US hybrid model for regulating animal research, including the IACUC.
- Learn the trichromatic theory, explaining color perception through three cone types.
- Understand the opponent process theory, explaining why certain color combinations are impossible.
- Discover how both trichromatic and opponent process theories are correct at different stages.
- Learn how binocular cues, like disparity, create the perception of 3D space.
- Identify monocular cues that allow depth perception with a single eye.
