What is blindsight in psychology quizlet?

ability to detect and identify visual stimuli by forced-choice guessing when stimuli are in blind parts of visual
field. – detection without conscious awareness.
What is the interdisciplinary study of how brain activity is linked with our mental processes?
Cognitive neuroscience
is the interdisciplinary study of how brain activity is linked with our mental processes. It is helping us to understand how specific brain states relate to conscious expe- riences. Most cognitive neuroscientists
What do blind people see?
A person with total blindness won’t be able to see anything
. But a person with low vision may be able to see not only light, but colors and shapes too. However, they may have trouble reading street signs, recognizing faces, or matching colors to each other. If you have low vision, your vision may be unclear or hazy.
