Began a virtual dialogue series named "Dialogues in Science" for the National Library of Medicine. These virtual dialogue programs feature renowned physicians, scientists, and other leaders in medicine and the biosciences. The programs, which are maintained on a kiosk in the NLM Visitors Center at the Lister Hill National Center for Biomedical Communications, allow the public to "meet" these remarkable people and learn about their accomplishments through simulated "face-to-face" conversations with them.

Virtual Dialogues with Native Speakers: The Evaluation of an Interactive Multimedia Method. CALICO Journal, Special Issue: Tutors that Listen - Speech Recognition for Language Learning, 16:3(313-337), Spring 1999. Study involving short-term use of the virtual dialogue Arabic Series (Modern Standard Arabic and Iraqi dialect) by linguists in a refresher course at the Defense Language Institute. Participants were evaluated with standard DLI testing procedures and demonstrated remarkable gains in speaking, listening comprehension, reading, and confidence using the language after only four days.
The Effect of Race and Sex on Physicians' Recommendations for Cardiac Catheterization. The New England Journal of Medicine, 340:618-626, February 25, 1999. NIH-funded study conducted by researchers at the Georgetown University Medical Center using interactive simulated patients developed by Interactive Drama. The findings suggested that the race and sex of a patient independently influence how physicians manage chest pain.

TIME Project Interactive Patient Simulations: Experiential Learning in the Medical School Classroom. Journal of Medical Education Technologies, 2:4(3-8), Spring 1992. Study conducted at three major medical schools that established the feasibility of using the virtual dialogue method to introduce second-year medical students to patient interviewing and clinical problem solving. The findings demonstrated that students became intellectually and emotionally involved in the learning experience, they perceived the patients to be real people, and they enjoyed this method of learning.

A field test of the TIME Patient Simulation Model.
Academic Medicine 1990; 65(5):327-333. This article describes a rigorous scientific field study of the first virtual dialogue patient simulation model developed by IDI principals. The study, funded by NIH, was conducted at three major medical schools and involved 306 second-year medical students. The principal finding was that, in a group setting, a large majority of the students became individually committed to the care and management of the simulated patient. They acted as if the patient's problems were real and left the session feeling as though they had interacted with an actual person. In terms of simulated a real patient, the TIME model was validated, providing the basis for the development of new patient-centered methods to teach and test medical students.
