Associate Professor Ann Packman's research encompasses all aspects of stuttering; namely, its nature, cause and treatment. She has a particular interest however, in the nature of stuttering and in the possible mechanisms underlying fluency enhancing conditions and successful behavioural treatments. In a recent book co-author Joseph S. Attanasio from Montclair State Univerity and Packman overviewed scientific principles for evaluating theories, such as falsifiability and applied these to theories of stuttering. With colleagues, she has also developed a model of stuttering, the variability or V model, which explains the ameliorative effects on stuttering of prolonged speech and rhythmic speech. The lab work which prompted this model also formed the empirical base for the development of the Camperdown Program
