Dr. Leonard L. LaPointe, professor in the College of Communication at Florida State University, presented on August 24, 2007. His lecture was the 2007 Anthony B. DeFeo Lecture in Speech-Language Pathology. Leonard L. (Chick) LaPointe, an internationally known expert in communications disorders, will give the first lecture in a new series honoring The University of Arizona's Anthony B. Defeo. DeFeo directs child and adult speech-language and hearing clinics in the UA department of speech, language and hearing sciences. LaPointe discussed his research that measures how simultaneous talking and walking jeopardizes people who have cognitive and language disorders. One recent study reports that 68 percent of people with Parkinson disease, for example, risk injurious falls when they are distracted by talking while they walk.
