Dr. Henry Freund was one of the foremost authorities on stuttering in Europe, and his contributions on the psychology of the disorder continued after emigrating to this country. He was a neurologist and psychiatrist, as well as a speech pathologist. He died in 1982, and in this posthumous paper he describes his career and personal experiences, while undergoing therapy from the most famous European speech pathologists of his time. He also offers some cogent comments about current therapies and future needs. 相似文献

Eliminating selective stimulus control: a comparison of two procedures for teaching mentally retarded children to respond to compound stimuli 总被引:3,自引:0,他引:3
Selective stimulus control occurs when behavior fails to come under control of all characteristics of a compound stimulus after discrimination training. Two different assessment procedures, one used in prior research and the other incorporating incorrect stimuli (S - 's) which differed minimally from the correct stimulus (S+), were used to detect stimulus control deficits characteristic of selective stimulus control. The efficacy of two training procedures in eliminating selective stimulus control observed with three trainable mentally retarded children was evaluated in Experiment 1. A training procedure using S - 's that were minimally different from the S+ was designed to reduce the probability that stimulus discriminations could be based on stimulus characteristics other than experimenter-specified characteristics defining the S+. This procedure proved more effective in preventing and eliminating selective stimulus control as measured by both assessment procedures than an alternate discrimination training procedure that failed to impact the more stringent measures of selective stimulus control. Experiment 2 indicated that these improvements in stimulus control were not a function of varying degrees of difficulty between stimulus sets or of a prior history of discrimination training with the less effective training procedure. The need for better assessment procedures to detect selective stimulus control and suggestions for further improvements in discrimination training procedures are discussed. 相似文献
