A rapid method of eliminating stuttering by a regulated breathing approach

The Habit Reversal Procedure for eliminating nervous habits was applied to the problem of stuttering. In the new procedure the speaker interrupted his speech at moments of actual or anticipated stuttering and at natural pause points, and resumed speaking immediately after breathing deeply during the pause. In addition to this regularized pausing and breathing, the program included other factors such as formulation of one's thoughts prior to speaking, identification of stutter-prone situations, identification of mannerisms associated with stuttering, speaking for short durations when tense or nervous, daily breathing exercises, relaxation procedures for anxiety, immediate display of improved speaking, and enlisting family support for progress. Fourteen stutterers were given training in the program during a single counseling session of about two hours duration. The next day, the average number of stuttering episodes decreased by 94 per cent, by 97 per cent at the end of one month, and by 99 per cent during the extended follow-up. Each of the clients was improved by at least 93 per cent. The new procedure appears to be more rapid and effective than alternative procedures.     

Dry bed: A rapid method of eliminating bedwetting (enuresis) of the retarded

Bedwetting has been a major and unsolved problem for the severely retarded. To solve this problem, an intensive training program was designed similar to a recently developed program for daytime toilet training of the retarded. Some distinctive features of the new procedure were frequent positive reinforcement for correct toileting, a negative reinforcer for accidents, positive practice in night time toileting, increased level of urination by forcing drinking, immediate detection of correct and incorrect toileting, and Positive Practice for accidents. Of twelve retarded adult bedwetters, the average bedwetter required only one night of intensive training. Several days of apparatus monitoring were used following the training but proved unnecessary for two-thirds of the trainees. Accidents were reduced by about 85 % during the first week after training, and almost entirely (95%) during the fifth week with no relapse during a 3 month follow-up. No reduction of accidents resulted when the same bedwetters were given a control procedure that provided no positive or negative reactions other than the sounding of an alarm upon bedwetting. The Dry-Bed procedure appears to be a very rapid solution to the problem of enuresis among the retarded and may be applicable to other difficult populations and also to normals.     

Using awareness training to decrease nervous habits during public speaking

This study evaluated the effectiveness of awareness training for the reduction of three nervous habits that manifest during public speaking: filled pauses, tongue clicks, and inappropriate use of the word “like.” Four university students delivered short speeches during baseline and assessment sessions. Awareness training resulted in meaningful reductions in target behaviors for all participants. Booster awareness training sessions were necessary for all participants to achieve further reductions in target behaviors. Generality probes conducted in front of a small audience indicated that treatment effects generally maintained. Social validity scores indicated that the treatment was acceptable, and participants indicated not only decreased use of verbal fillers, but also improved overall public speaking ability posttreatment.     

A reinforcement plus interruption method of eliminating behavioral stereotypy of profoundly retarded persons

Stereotyped responses have been shown to be eliminated by an overcorrection-reinforcement program. The present study evaluated response-interruption as an alternative to the overcorrection component with seven profoundly retarded adults. During the baseline praise condition, stereotypy occurred during 66% of the observations for the seven profoundly retarded adults but decreased to less than one response per half hour in a mean of two sessions of individual training. In the subsequent class situation, stereotypy was reduced to less than 5% on the first day of class, to less than 1% by the fourth day and less than one stereotypy per hour after the third day. The interruption method seems preferable to postural overcorrection because of its apparent and relative nonaversiveness.     

A method for increasing empirical discriminability and eliminating top‐row preference in photo arrays

It is important to consider the two parameters of signal detection theory, discriminability and response bias, when evaluating eyewitness identification from simultaneous lineups. On the basis of the diagnostic feature‐detection hypothesis, we tested a method for increasing discriminability that encourages eyewitnesses to carefully rank each lineup member based on match to their memory for a perpetrator. This procedure increased empirical discriminability and also eliminated a response bias that is largely overlooked in the literature: Participants were biased to choose from the top row of the six‐pack (2 × 3) lineup commonly used in the United States. We argue that suspect position in the simultaneous lineup is an important variable to consider for researchers and the criminal justice system. We also encourage researchers to test the ranking procedure to determine if such a simple set of instructions could be utilized by police to help eyewitnesses correctly sort innocent versus guilty suspects.     

Observations and ratings of tics in school settings

This paper describes the findings of a school-based tic assessment procedure (direct observations, teacher rating scales) for hyperactive children with comorbid tic disorder. Rates of motor tic frequency were found to be moderately stable across both days and school settings. Correlations between direct observations of tics and clinician rating scales were generally in the low to moderate range as were correlations between teacher and clinician rating scales. Overall rates of hyperactive/disruptive behaviors were not associated with rates of motor tic occurrence, and the behavioral symptoms of both disorders were also independent for specific intervals of time.This study was supported, in part, by a research grant from the Tourette Syndrome Association, Inc., and P.H.S. grant MH 45358 from the National Institute of Mental Health. The authors wish to thank Joyce Sprafkin for providing valuable clinical services related to the conduct of the school-based medication evaluations and Joseph Schwartz for assisting with the data analyses. We are particularly indebted to the families and teachers who made this study possible.     

A comparison of several procedures for eliminating behavior

The pecking response of pigeons was reinforced when a minimum period of time had elapsed since the last response (DRL schedule of food-reinforcement). Punishment, satiation, extinction, and stimulus change were employed separately to reduce responding. When the effects of the four procedures were compared, punishment was found capable of producing a more immediate, complete and long lasting response reduction than the others. Punishment had its maximum effect on the responses that were least relevant to reinforcement. The punishment reduced the frequency of the short inter-response times to a greater extent than did either extinction or satiation. In this way, punishment actually increased the efficiency of the DRL responding.     

A retrieval-based approach to eliminating hindsight bias

Individuals exhibit hindsight bias when they are unable to recall their original responses to novel questions after correct answers are provided to them. Prior studies have eliminated hindsight bias by modifying the conditions under which original judgments or correct answers are encoded. Here, we explored whether hindsight bias can be eliminated by manipulating the conditions that hold at retrieval. Our retrieval-based approach predicts that if the conditions at retrieval enable sufficient discrimination of memory representations of original judgments from memory representations of correct answers, then hindsight bias will be reduced or eliminated. Experiment 1 used the standard memory design to replicate the hindsight bias effect in middle-school students. Experiments 2 and 3 modified the retrieval phase of this design, instructing participants beforehand that they would be recalling both their original judgments and the correct answers. As predicted, this enabled participants to form compound retrieval cues that discriminated original judgment traces from correct answer traces, and eliminated hindsight bias. Experiment 4 found that when participants were not instructed beforehand that they would be making both recalls, they did not form discriminating retrieval cues, and hindsight bias returned. These experiments delineate the retrieval conditions that produce—and fail to produce—hindsight bias.     

Making and breaking habits: Revisiting the definitions and behavioral factors that influence habits in animals

Habits have garnered significant interest in studies of associative learning and maladaptive behavior. However, habit research has faced scrutiny and challenges related to the definitions and methods. Differences in the conceptualizations of habits between animal and human studies create difficulties for translational research. Here, we review the definitions and commonly used methods for studying habits in animals and humans and discuss potential alternative ways to assess habits, such as automaticity. To better understand habits, we then focus on the behavioral factors that have been shown to make or break habits in animals, as well as potential mechanisms underlying the influence of these factors. We discuss the evidence that habitual and goal-directed systems learn in parallel and that they seem to interact in competitive and cooperative manners. Finally, we draw parallels between habitual responding and compulsive drug seeking in animals to delineate the similarities and differences in these behaviors.     

Functional analysis and habit‐reversal treatment of tics

Although there is empirical support for a biological etiology of Tourette syndrome and other tic disorders, researchers have recently begun examining the role of reinforcement in tic maintenance. Using experimental functional analyses, researchers have identified both social and nonsocial functions for the tics of a variety of individuals. However, there are at least two problems with this developing literature. First, all but one of the studies employed a single participant and many of them were referred for clinical treatment. These factors leave open the possibility that the selection or referral process may have contributed to the reported outcomes. Second, five of the seven participants had a developmental disability or delay. Thus, the majority of participants in this literature are unrepresentative of most individuals with tic disorders. The purpose of the present study was to investigate the operant functions of the tics of multiple children who were recruited for the study. We evaluated the tics of three typically developing children using functional analysis. Results indicated nonsocial functions for all tics. Two of the participants were then treated using habit reversal; both of them experienced tic reductions. Copyright © 2005 John Wiley & Sons, Ltd.     

Sensory Extinction: A procedure for eliminating self-stimulatory behavior in developmentally disabled children

This study was designed to investigate the role of sensory reinforcement in the motivation of self-stimulation. If self-stimulatory behavior is maintained by its sensory consequences, such as the proprioceptive, auditory, or visual stimulation it produces, then such behavior should extinguish when those sensory consequences are not permitted. The present study introduces a new procedure, Sensory Extinction, in which certain sensory consequences are masked or removed, to examine whether self-stimulation is operant behavior maintained by sensory reinforcement. The effectiveness of Sensory Extinction was assessed by a reversal design for each of three autistic children, and the results showed the following. First, self-stimulation reliably extinguished when a certain sensory consequence was removed, then increased when that consequence was permitted. This was replicable within and across children. Second, different Sensory Extinction procedures were required for different self-stimulatory behaviors, since the sensory reinforcers supporting them were idiosyncratic across children. Finally, regarding clinical gains, the data suggest that Sensory Extinction may be a relatively convenient and rapid alternative for the treatment of self-stimulation. The present findings extend the efficacy of extinction as a behavior-modification technique to instances in which the reinforcer is purely sensory. The implications of these results for the treatment of other forms of deviant behavior are discussed.
