Across
- 4. A phenomenon that causes sensory crossovers, such as tasting colors or feeling sounds
- 7. The process of detecting and encoding environmental stimuli. It involves our sensory systems working together to capture information.
- 8. Specialized nerves that convert light into neural impulses. They are responsible for color vision and are concentrated in the fovea, the central area of the retina.
- 9. The smallest change in a stimulus that can be detected 50% of thetime.
- 11. States that different frequencies of sound stimulate different places along the basilar membrane in the cochlea, leading to pitch perception
- 13. Describes the degree stimuli need to differ for the difference to be detected.
Down
- 1. Inability to recognize faces.
- 2. The lowest level of a stimulus that a person can detect 50% of the time.
- 3. Explains color vision through three types of cones in the fovea processing color and detail. Blue cones detect short wavelengths,green detects medium, and red detects long wavelengths.
- 5. Adds to trichromatic theory by considering that yellow and blue cones back each other up, as green/red and black/white do. These pairs have complementary after images.
- 6. Suggests that groups of auditory nerve fibers fire in rapid succession, combining to encode higher frequency sounds that a single neuron can't process on its own.
- 10. Ability to respond to visual stimuli without consciously perceiving them.
- 12. Cells that lie in the periphery of the eye and detect shapes and movement, but not color. Mainly activated in low-light environments. Play a role in light and dark adaptation.
