Selective Mutism (Psychology Revivals) [PDF ebook] 
Implications for Research and Treatment

Originally published in 1981, this title was designed to present a comprehensive review of research on, and treatment of selective mutism. It represents the only systematic overview of research and treatment procedures on this behavioral problem at the time. In many respects the literature on selective mutism clearly presents the differences in assessment and treatment between the intrapsychic (or psychodynamic) and behavioral approaches to deviant behaviour. The title presents an overview of the two major therapeutic approaches of human behaviour within the context of treating selective mutism.
