Brief summary

The purpose of this study is to determine brain function in reading arabic diacritics.

Detailed description

fMRI is a well established imaging technique that allows investigators to see regional brain function based off of actions like reading, speaking, playing music, etc. Even the type of language and format of that language can change the area of the brain that is active while performing that action. This study is meant to see the areas of the brain that become active both prior to and during the process of reading diacritic markings in arabic.

Interventions

OTHERMRI

All subjects will be asked to lay in an MRI for about an hour while reading Arabic diacritic characters
