The study procedures consist of testing your speech, language, memory and organization. For the language tests you will be asked to compare the sounds and meanings of words, name and describe pictures, repeat words and sentences, and retell stories. For the memory tests, you will be asked to repeat a series of numbers and words, and identify numbers and words in the series. For the tests of your organizational abilities, you will be asked to recognize blocks and pictures, and organize letters and numbers. The purpose of this testing is to figure out how language and memory affects your ability to listen to, understand, remember and say words and sentences.
