THE REDUCTION OF STEALING IN SECOND GRADERS USING A GROUP CONTINGENCY1

Three classes of second graders served as subjects in this study of the effects of two types of intervention programs upon stealing: (1) an antistealing lecture with no specific contingency implied, and (2) a direct group contingency applied, whereby children were rewarded with (a) extra free time for no thefts, (b) allowed normal free time if stolen items were returned, and (c) punished with loss of free time if stolen items were not returned. A multiple-baseline design across the three classes showed the group contingency to be effective in reducing stealing behavior; the anti-stealing lecture was ineffective.     

Theft reduction in a grocery store through product identification and graphing of losses for employees

Shoplifting and employee theft constitute a major problem for retailers. Previous research has described techniques for effectively reducing either type of theft but has not addressed the problem of thefts of unspecified origin. In a grocery store we evaluated the effect of identifying for employees frequently stolen products from three groups of items and graphing, twice weekly in the lunchroom, losses for the separate groups. After the products were identified and losses graphed, thefts from the three groups dropped from eight per day to two per day.     

Overcorrection: Reviewed, revisited and revised

Overcorrection is a widely used behavior management procedure, the success of which has been well documented. However, overcorrection is not a simple, single procedure. Rather, it is a complex combination of procedures that often make it a complicated strategy to understand conceptually and to implement correctly. The complex nature of overcorrection combined with the use of multiple labels has created much confusion and debate among both researchers and practitioners. A number of issues relating to overcorrection are examined and evaluated. A proposal is made for revising the present overcorrection terminology. Finally, directions for future research are suggested.     

Children's understanding of ownership transfers

An understanding of ownership entails the recognition that ownership can be transferred permanently and the ability to differentiate legitimate from illegitimate transfers. Two experiments explored the development of this understanding in 2-, 3-, 4- and 5-year olds, using stories about gift-giving and stealing. The possibility that children use simple biases to identify owners, such as a first possessor, current possessor or a loan bias, was also investigated. Five-year olds appropriately acknowledged a permanent transfer of ownership in the case of giving but not stealing. Four-year olds allowed permanent transfers but struggled to differentiate legitimate from illegitimate transfers. Many 4-year olds allowed adults, but not children, to keep property that had been stolen. Two- and 3-year olds exhibited a first possessor bias for both stories. We conclude that, by 5 years of age, children possess a mature understanding of ownership transfer whereas younger children are prone to biases.     

Food stealing by young Norway rats (Rattus norvegicus)

Six experiments were undertaken to explore factors affecting young rats' (Rattus norvegicus) frequencies of stealing food from conspecifics when identical food is available in surplus. It was found that (a) rats would walk across a bed of pellets to steal the particular pellet a peer was eating, (b) frequency of stealing within a pair did not decrease over days, (c) rats stole unfamiliar foods more frequently than familiar foods, (d) younger rats stole from older rats more frequently than older rats stole from younger ones, (e) hungry rats stole more frequently than replete rats, and (f) rats that had stolen a pellet of unfamiliar food from an anesthetized conspecific subsequently exhibited an enhanced preference for that food. Results suggest that food stealing is a mode of active seeking of information about what foods to eat.     

INCREASING SPELLING ACHIEVEMENT: AN ANALYSIS OF TREATMENT PROCEDURES UTILIZING AN ALTERNATING TREATMENTS DESIGN

Two studies which examine the effectiveness of spelling remediation procedures are reported. In both studies, an alternating treatment design was employed. In the first study, positive practice overcorrection plus positive reinforcement was compared to positive practice alone and a no-remediation control condition. In the second study, positive practice plus positive reinforcement was compared to a traditional corrective procedure plus positive reinforcement and a traditional procedure when used alone. Results of both studies indicated that the combined positive practice plus positive reinforcement procedure was more efficient and that it was preferred by the children. Following brief training under this combined procedure, all children demonstrated 100% spelling accuracy.     

Sex differences in bystander intervention in a theft

A series of studies demonstrated a strong relationship among the situation-defining variable of degree of harm to victim, sexual configuration among participants, and bystanders' willingness to intervene to stop a theft. A pretest showed that a prior verbal commitment was absolutely necessary for intervention. The remaining data showed that high harm to a victim produced a high rate of intervention and showed strong sex differences in helping behavior in low-harm conditions. A high percentage of female bystanders helped in both low- and high-harm situations, whereas frequent helping by males was observed only when harm to the victim was high. Female victims elicited a significantly greater amount of helping, and sex of thief had no effect. A significant sex of bystander, sex of victim, and harm to victim interaction best describes the data. Results are interpreted in terms of different motivational sets held by males and females when they are responsible for the fate of others. Results also support the utility of an interactionist approach to the question of how individual and situational variables influence prosocial action.     

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.     

Effectiveness of hand overcorrection for topographically similar and dissimilar self-stimulatory behavior

Response contingent hand overcorrection was used to reduce the frequency of self-stimulatory behaviors in four retarded adult males. For two of the subjects, the treated behaviors (hand shaking and nose touching) involved hand movements which were topographically similar to the hand overcorrection procedure. For the other two subjects, behaviors topographically dissimilar to the treatment procedure were treated (inappropriate laughing and head weaving). All four behaviors were decreased in frequency during treatment. However, the hand overcorrection procedure was more effective with the topographically similar behaviors.     

An overcorrection framing effect

With the “typical” attribute framing manipulation, assimilation effects have often been obtained; people often judge the attributes of a judgmental target more positively when the attributes are framed positively (e.g., 99% pure) than negatively (e.g., 1% impure). Research has not, however, explored or demonstrated the effects of correcting or overcorrecting for the frame's influence. Overcorrection framing occurs when a more positive response is produced by the negative frame. Across three experiments, overcorrection as well as typical framing effects were obtained. In Experiments 1 and 2, overcorrection effects were obtained when participants were prompted to consider complementary information and, in Experiment 3, when the frame's source was described as untrustworthy. In contrast, typical framing effects were obtained when prompts were not supplied and when the frame's source was not described as being untrustworthy. These results supported the unification model that uses a priming analysis to account for assimilation (typical framing) and contrast (overcorrection framing) effects. We discussed how overcorrection is expected with other framing manipulations, such as risky-choice framing. We provided reasons for asymmetrical correction effects and discussed implications of our analysis for holistic/analytical as well as System 1/System 2 processing styles, the influence of different amounts of cognitive resource allocations, and the possibility of a correction process involving averaging.     

Facilitating Accuracy in Showup Identification Procedures: The Effects of the Presence of Stolen Property

Law enforcement personnel regularly present suspects to eyewitnesses using showups. In this study, we examined the impact of the presence of stolen property on live showup identification performance. Two hundred seventy university students were exposed to a simulated theft. During the subsequent showup, we manipulated the presence of the target and stolen property. Binary logistic regression analyses indicated that both factors independently predicted the accuracy of identification decisions. Participants were more accurate when the target was in the showup and when the stolen property was present during the identification. Consistent with the item, context, and ensemble theory of recognition, the presence of stolen property led to an increase in sensitivity, suggesting ensemble formation. Future research on showups should continue to examine contextual variables that may lead to changes in sensitivity or criterion shift. Copyright © 2012 John Wiley & Sons, Ltd.     

Differentiating sex offences: a behaviorally based thematic classification of stranger rapes

It is hypothesized that stranger rape victim statements will reveal a scale of violation experienced by the victim, ranging from personal violation, through to physical violation, and finally, at the most extreme level, sexual violation. It is also hypothesized that offences can be differentiated in terms of one of four themes: hostile, controlling, stealing, or involving. To test these hypotheses, crime scene data from 112 rapes were analyzed by the multi-dimensional scaling procedure Smallest Space Analysis. The results provide empirical support for a composite model of rape consisting of four behavioral themes as different expressions of various intensities of violation. The results also suggest that stranger rapes may be less about power and control than about hostility and pseudo-intimacy. The proposed model has implications for the classification of rape, the investigation of sexual crimes, and the treatment of victims.     

GENERALITY AND SIDE EFFECTS OF OVERCORRECTION1

The effects and side effects of overcorrection for self-stimulatory behaviors of two children in a specialized day-care program were evaluated. For one child, a “hand” overcorrection procedure involving arm and hand exercises was introduced contingent upon inappropriate hand movements and later contingent upon inappropriate foot movements. After “hand” overcorrection was withdrawn for inappropriate foot movements, a “foot” overcorrection procedure involving foot and leg exercises was introduced contingent upon inappropriate foot movements. For a second child, the “hand” overcorrection procedure was introduced contingent upon inappropriate hand movements during a free-play period, and later contingent upon inappropriate vocalizations at naptime. “Hand” overcorrection was withdrawn and then re-introduced sequentially for both behaviors. Several concurrent behaviors were measured to assess multiple effects of treatment. Results for both children indicated the “hand” overcorrection procedure suppressed inappropriate hand movements and inappropriate behaviors that were topographically dissimilar. In addition, inverse relationships were observed between the second child's inappropriate hand movements and appropriate toy usage during free play and between his inappropriate vocalizations and inappropriate foot movements during naptime. Results suggest that overcorrection procedures that are effective for one behavior can be used to reduce the frequency of topographically different behaviors. This finding is discussed in terms of its practical implications for therapists.     

Effects of prior knowledge and response bias upon recognition memory for a story: Implications for children's eyewitness testimony

Abstract: The present study was designed to evaluate the integration hypothesis and the response bias hypothesis for explaining the fragility of children's eyewitness memory, by varying the plausibility of postevent information and the strength of response bias in recognition tests. Preschool children were told a story in which a boy named Ken saw a housebreaker stealing various objects and the postevent information was also incorporated into the story. The first recognition test was administered immediately following the presentation of an interpolated story, and the second recognition test was administered 10 weeks later. The results indicated that high-plausibility objects tended to be recognized as the stolen objects in the second recognition test, and that recognition accuracy was higher for a new-distractor condition than for a misleading-distractor condition. These findings were interpreted as suggesting that the memory representation of the story might be changed through the integration processes and/or rendered inaccessible in terms of the response bias.     

RECREATING THE SCENE: AN EFFECTIVE WAY TO PROVIDE DELAYED PUNISHMENT FOR INAPPROPRIATE MOTOR BEHAVIOR

A mediated punishment procedure that involved recreating a behavioral sequence by guiding the subject through the behavior in the situation in which it occurred was used to suppress several severe problem behaviors in two developmentally delayed children. The mediational procedure was first used with a 4-year-old autistic boy for biting and then for foot stomping. Next the procedure was used for stealing and hoarding behavior with a multiply handicapped 17-year-old girl. Results indicated that the procedure was effective and produced relatively rapid results. One advantage of the procedure is that it provides an opportunity for trained personnel to apply restrictive procedures to low frequency behavior that occurs in their absence rather than relying on less qualified staff to implement the procedure immediately after the behavior occurs.     

Treatment of covert food stealing in an individual with Prader-Willi syndrome

Covert food stealing is common among individuals with Prader-Willi syndrome. We found that verbal reprimands, delivered contingent upon eating prohibited foods, were sufficient to decrease the food stealing of a girl with Prader-Willi syndrome. Warning stimuli were then used to help her discriminate between permitted and prohibited foods during sessions in which food stealing was not directly observed. This procedure resulted in decreases in food stealing from containers labeled with the warning stimuli.     

OVERCORRECTION: GENERALIZATION AND MAINTENANCE1

The present study examined the effects of one component of overcorrection—verbal reprimands—and compared them with the effects of the entire overcorrection procedure. Generalization and maintenance of effects were also evaluated. A combined reversal and multiple-baseline experimental design was used to evaluate the effect of the various contingencies on the inappropriate searching behavior of a severely and profoundly mentally retarded adult living in a group home. Searching was defined as carefully and thoroughly touching floors, sofas, cabinets, etc. Data were collected by group-home personnel during three separate observation periods each day of the 115-day study: before breakfast, after breakfast, and after dinner. Observers also served as experimenters. Following an initial baseline phase, verbal reprimands followed searching behavior during two daily experimental periods in multiple-baseline fashion. An immediate reduction of searching during experimental periods occurred with the onset of verbal reprimands. No reduction was observed in the third daily observation period, the control session. After a second baseline phase, during which searching behavior was not shown to return to the original baseline levels, overcorrection procedures (washing hands) were instituted. Overcorrection virtually eliminated inappropriate searching during both daily experimental periods. Further, the effects generalized to the daily control session. In a final experimental phase, decreased searching behavior was maintained with verbal reprimands alone.     

Expectations and prescriptions for responding to peer aggression: The adolescent offenders' perspective

The purpose of the current research was to investigate adolescent offenders' perspectives about responses to interpersonal aggressive encounters. Specifically, participants' perspectives were assessed regarding the role of a bystander when either a friend or an acquaintance of the bystander was the victim of an aggressive act. Two aggressive acts were presented. First, the bystander witnessed an acquaintance stealing from the victim. Second, the bystander witnessed an acquaintance hitting the victim. Participants were asked to indicate (a) if the bystander would do anything (bystander expected behavior), (b) what the bystander would do (expected behavioral action), (c) if the action would be the right thing to do (evaluation of bystander expected behavioral action), and (d) what the bystander should do in response to the violation (prescribed bystander behavioral action). Results indicate that the adolescent offenders' perspectives varied as a function of offender status, type of aggressive act, as well as relationship of the victim to the bystander. Aggr.

SUPPRESSION OF SELF-STIMULATION: THREE ALTERNATIVE STRATEGIES

Four boys with autistic-like behavior were treated for self-stimulatory behavior with three different treatment procedures—time-out, differential reinforcement of other behavior (DRO), and overcorrection. All four boys showed a rapid response to the overcorrection procedure. Three boys demonstrated some evidence of decrement in responding with time-out. During the DRO procedure, one showed a modest decrease, two showed no change, but one exhibited a consistent increase in responding under this condition. A multiple baseline applied to one of the subjects failed to reveal any generalization of suppression from one setting to another. A strong but not perfect relationship was found between a frequency and a duration measure of self-stimulation. There was some evidence of negative side effects for one boy during overcorrection and for another during time-out. None of these negative side effects was enduring. There was also some indirect evidence that overcorrection facilitated appropriate play.
