In the previous experiment, most people show a right visual field advantage.
Let’s look at the stages of processing that lead to this advantage
in a right-hander with left hemisphere specialization for language.
When a word is presented to the right visual field, the word goes
directly to the left hemisphere, where it is processed and identified.
When a word is presented to the left visual field, it is first processed in the right hemisphere,
and then passes across the corpus callosum to be identified in the left hemisphere.
Researchers believe that transferring information from the right hemisphere to the left hemisphere
may lead to a loss of clarity, resulting in poorer identification of the words presented to the left visual field.
