Across
- 2. The colored part of the eye that controls pupil size
- 4. Stimulus A stimulus below the level of conscious awareness
- 6. Photoreceptors that help with vision in dim light
- 11. The process of detecting stimuli from the environment
- 13. The light-sensitive layer at the back of the eye
- 15. When stimulation of one sense triggers an experience in another sense
- 17. The study of how physical stimuli relate to sensations
Down
- 1. The opening in the eye that allows light to enter
- 3. Adaptation Decreased sensitivity after constant exposure to a stimulus
- 5. Photoreceptors responsible for color vision and fine detail
- 7. Threshold The smallest difference between two stimuli that can be detected
- 8. The sense of hearing
- 9. The clear outer covering of the eye that helps focus light
- 10. Law The JND depends on a constant proportion of the original stimulus
- 12. Interaction When one sense influences another
- 14. Converting physical energy into neural signals
- 16. Threshold The minimum stimulation needed to detect a stimulus 50% of the time
