Behavioral engineering: stuttering as a function of stimulus duration during speech synchronization

Past studies have shown that stuttering is eliminated when speech is synchronized with a metronomic beat, but the speech sounds artificial. The present study investigated the effect of increasing the duration of these individual stimulus beats with the stimulus-off period constant at 1 sec. When subjects were instructed to speak during the stimulus-on period, stuttering was an inverse function of stimulus duration, indicating that the known metronome effect on stuttering is one point on a continuum of effective rhythm procedures. The "naturalness" of speech increased as the stimulus duration increased up to durations of about 2 sec, and then decreased. At optimal values, stuttering was greatly reduced and naturalness and rapidity of speech were retained. These optimal values effectively controlled stuttering in a field test that used two types of specially designed portable instruments, one of which produced a tactual stimulus and the other an auditory stimulus.     

Good behavior game: effects of individual contingencies for group consequences on disruptive behavior in a classroom

Out-of-seat and talking-out behaviors were studied in a regular fourth-grade class that included several "problem children". After baseline rates of the inappropriate behaviors were obtained, the class was divided into two teams "to play a game". Each out-of-seat and talking-out response by an individual child resulted in a mark being placed on the chalkboard, which meant a possible loss of privileges by all members of the student's team. In this manner a contingency was arranged for the inappropriate behavior of each child while the consequence (possible loss of privileges) of the child's behavior was shared by all members of this team as a group. The privileges were events which are available in almost every classroom, such as extra recess, first to line up for lunch, time for special projects, stars and name tags, as well as winning the game. The individual contingencies for the group consequences were successfully applied first during math period and then during reading period. The experimental analysis involved elements of both reversal and multiple baseline designs.     

JOB DEVELOPMENT FOR THE MENTALLY RESTORED PSYCHIATRIC PATIENT1

The experiences of the placement department of the Mental Health and Manpower Project have demonstrated that an effective team can be created to develop job opportunities for the mentally restored psychiatric patient. Composed of a vocational counselor and a placement counselor, the team is effective in securing meaningful employment and developing re-education programs in the community. While the vocational counselor provides the clinical information concerning the restored patient-client, the placement counselor serves as a more personnel oriented individual in finding the appropriate kind of employment position. The team points to the potential that the mental health center possesses in involving the general community in its programs.
