2007 Winter Symposium: Training Classes: Lidia Lee

DR. LIDIA LEE
Dr. Lidia Lee received her doctorate in Audiology from Indiana University, Bloomington, Indiana.  Her undergraduate degree was completed at Whittier College Scholar Program with a focus in Experimental Psychology. 

In the past 15 years, Dr. Lee’s research activities have focused on psychoacoustics, primarily issues related to perception and sound quality of audio systems and speech recognition among individuals with hearing impairment.  Her research places a heavy emphasis on quantitative research designs where double blind testing is often a requirement.  Dr. Lee’s research has been published in numerous peer- reviewed journals and includes such topics as the perception of nonlinear distortion, the perception of group delay in audio systems and the quantification of sound quality issues in compression drivers. 

Dr. Lee obtained tenured professorship at both Northern Illinois University and Eastern Michigan University.  She is also a principal researcher at GedLee, LLC where she collaborates with Dr. Earl Geddes, her husband.  She resides in Michigan with Earl, and their 8 year-old son, Nathan.

Facts versus opinions can often be the determining factor in critical decisions in the design process. The difference between the two is if a claim is supported by a scientific process or research.  In this session, we will discuss potential errors in decisions that use opinions as fact.  We will discuss evidence-based research methods and the various components and steps that are involved in experimental design, including ‘blind’ designs.  We will also include steps involved in conducting an experimental study such as how to formulate a hypothesis, issues relating controlling variables, test validity and reliability, internal versus external validity and accuracy and basic statistical techniques and analyses.  A solid understanding of the foundation of how a research task should be conducted will allow you to critically analyze the information presented to you and how to determine its fact vs. opinion basis.  This information can then be used accordingly.
