Document Summary

Sensation: how sensory organs receive signals from the environment. Since these processes are different, we don"t immediately perceive what we sense. All sensory signals go through the thalamus. Occipital lobe: part of brain where most of visual processing occurs. Auditory cortex: located in the temporal lobe, hearing and sound are processed. The lowest level of stimulation that can be detected 50% of the time. The brain can process information without you being aware of it. As the initial intensity increases, it"s going to be harder and harder to detect change in that intensity. Hit: prediction and reality are true (yes) False alarm: prediction is wrong, detected something that wasn"t there. Miss: prediction is wrong, did not detect. Correct rejection: prediction and reality are true (no) Criterion: a principle or standard by which something may be judged or decided. The lower the value, the lower the threshold for someone to be able to detect something.
