METHODS Undergraduate psychology students (n = 140) were randomly assigned to receive reassuring or threatening information about the cold pressor. Participants were then(More)
Twenty adult and adolescent stutterers were randomly assigned to two treatment formats consisting of either 16 two-hour sessions of fluency training administered within a concentrated period of four consecutive days (intensive treatment), or two two-hour sessions per week for eight weeks (spaced treatment). Frequency of stuttering and rate of speaking were(More)
