Describe Split-Brain Experiments
Sperry was the first to study callosectomy patients. He thought hemispheres functioned
independently. Results should not be unreflectively generalized to non-split brain persons.
Gazzaniga suggested hemispheres functioned complementarily.
Methdology: in someone with a callosectomy. They are shown a brief image, left and right
side are different. The verbal response they give is about the right visual field (left cerebral
hemisphere) info. They use their LEFT hand to point about the left visual field (right
hemisphere) info. This suggests the left visual field info is processed by the right cerebral
hemisphere, and the right visual field info is processed by the left cerebral hemisphere. This
is probably due to the fact that Broca's and Wernicke's area are both in the left hemisphere.

Describe Cherry's Shadowing Experiment
In a dichotic listening experiment, different messages are played to different ears. In the
unattended ear, listener notices a change in gender, tone, and emotion, which are low level
sound properties (like feature). Also, the listener didn't notice a change in language or a
backwards recording, change in topic, or in speaker. These are high level semantic
properties (like conjunction).

Characteristics of Attention
- Produces actions.
- Filter out information that is important to us or that we want to attend to.
- Originates with sensations, memories, and thought processes.
- In limited supply.
Benefits of Attention
- respond more speedily and accurately to interesting or important stimuli.
- have a better memory for attended information.
- monitor our interactions with the environment.
- link the past (memories) with the present (sensations) to give continuity.
- control and plan future action.
