This monograph investigates the psychological mechanisms and experimental findings surrounding the etiology and treatment of stuttering. The authors, Fay Fransella and H.R. Beech, synthesize clinical observations with rigorous experimental data to challenge traditional views on speech dysfluency. By applying the principles of experimental psychology, they propose a framework that shifts the focus from purely physiological causes to the cognitive and behavioral patterns that sustain stuttering.

Experts recognize this text as a foundational contribution to the experimental study of speech disorders within the mid-20th-century psychological canon. Readers frequently note the academic density of the prose, which is intended primarily for clinicians and researchers in the field of experimental psychology.
