Application of social skills training in a group of institutionalized aggressive elderly subjects

A social skills training program consisting of instructions, modeling, role playing, and feedback was carried out with a group of 6 verbally aggressive institutionalized elderly patients. Dependent measures included confirmed incidents of verbal aggressive behavior monitored across an ABAB design with a 5-month follow-up period. Results indicated that verbally aggressive behavior can be significantly decreased in a group-training setting and subsequently generalized to ward and other socialized behavior. Ancillary aspects of the study include the role of social reinforcement, participant modeling, and staff attitude, perception, and motivation. Implications for future research are discussed.     

Multiple reinforcement contingencies to reduce aggression,self-injury and dysfunctional verbal behaviors in an adult who is sensory impaired

Differential reinforcement of other behavior (DRO) and differential reinforcement of low rates of responding (DRL) have been effective techniques in reducing maladaptive behaviors in therapeutic settings. Reported studies of these reinforcement-based procedures indicate that they are usually implemented in isolation, targeting only a single behavior or class of behaviors. In this study, multiple DRO and DRL contingencies were utilized concurrently in reducing two distinct classes of behaviors with a 26 year-old blind man with moderate retardation. One class of behaviors included socially inappropriate verbalizations, while the other included aggressive, self-injurious and environmentally destructive behaviors. Distinct contingencies were established according to the functions of the targeted behaviors and their severity and separate schedules of reinforcement were derived from baseline frequencies. Over a period of 20 months, the differential reinforcement interventions resulted in rapid reduction of behaviors in both classes to near-zero rates and frequencies were maintained at this low level while contingency schedules were systematically lengthened. Collateral effects are discussed including performance in functional academics and participation in community integration activities.     

Modification of severe disruptive and aggressive behavior using brief timeout and reinforcement procedures

Brief timeout for disruptive and aggressive behaviors and reinforcement for appropriate behaviors were used with two retarded patients in a state hospital ward setting. The procedures reduced loud vocal behavior in one patient and aggressive behavior in another to near-zero levels when first applied. The behaviors returned to previous levels when the procedures were removed and were again greatly reduced when timeout and reinforcement were reapplied. The results were significant because the behavior problems were severe and long-standing and the procedures were instituted without greatly disturbing normal ward routine.     

Behavior modification with culturally deprived school children: two case studies

Techniques of behavior modification were employed with two second-grade Negro girls in a demonstration school for culturally deprived children to increase the girls' appropriate classroom behaviors. A classification system that provided for continuous categorization of behavior was used to code the children's behavior in two classroom situations. Data were also taken on the type, duration, and frequency of the teachers' verbal interactions. The study included four conditions: Baseline, Modification I, Postmodification, and Modification II. The treatment variable was positive social reinforcement-attention and approval contingent upon desirable classroom behaviors-which was presented, withheld, or withdrawn (timeout from social reinforcement). Withholding of social reinforcement was contingent upon inappropriate attention-getting behaviors. Timeout from social reinforcement was contingent upon behaviors classified as aggressive and resistive. After 25 days of Modification I, desirable behavior increased markedly for each girl. The teachers were then asked to return to their Baseline level of performance. The resultant behaviors demonstrated that for one girl, behavior was still primarily under the control of the treatment contingencies. For the second child, many desirable behaviors that had increased in frequency during Modification I remained high, but inappropriate behaviors increased. When treatment was reinstated, the amount of time spent in desirable behaviors increased and remained high for both girls. Three checks during the three months following data collection showed that these behaviors continued to remain high.     

Escalation of irritable aggression: Control by consequences and antecedents

Two experiments demonstrated that rats could be trained in a negative reinforcement paradigm to display a shock-induced aggressive response on the first shock presented. Later, rats that had been submitted to the negative reinforcement training procedure displayed more shock-induced aggression than did control groups during a test session that was situationally different from the one used during training. A third experiment demonstrated that noxious antecedent events, if presented with sufficient rapidity, can combine to increase the probability of aggressive behavior. The three experiments together suggest that aversive antecedents and reinforcement contingencies could be involved in the escalation of irritable aggression.     

Social Identity and Youth Aggressive and Delinquent Behaviors in a Context of Political Violence

The goal of the current study was to examine the moderating role of in‐group social identity on relations between youth exposure to sectarian antisocial behavior in the community and aggressive behaviors. Participants included 770 mother‐child dyads living in interfaced neighborhoods of Belfast. Youth answered questions about aggressive and delinquent behaviors as well as the extent to which they targeted their behaviors toward members of the other group. Structural equation modeling results show that youth exposure to sectarian antisocial behavior is linked with increases in both general and sectarian aggression and delinquency over one year. Reflecting the positive and negative effects of social identity, in‐group social identity moderated this link, strengthening the relationship between exposure to sectarian antisocial behavior in the community and aggression and delinquency towards the out‐group. However, social identity weakened the effect for exposure to sectarian antisocial behavior in the community on general aggressive behaviors. Gender differences also emerged; the relation between exposure to sectarian antisocial behavior and sectarian aggression was stronger for boys. The results have implications for understanding the complex role of social identity in intergroup relations for youth in post‐accord societies.     

THE RELATIVE INFLUENCE OF MOTIVATING OPERATIONS FOR POSITIVE AND NEGATIVE REINFORCEMENT ON PROBLEM BEHAVIOR DURING DEMANDS

Research has demonstrated the feasibility of using positive reinforcement to treat problem behavior maintained by negative reinforcement. This line of research was extended in the current study. A functional analysis (FA) was conducted that suggested problem behavior was maintained by positive and negative reinforcement. Following the FA, a demand analysis was conducted with three demand conditions: one that replicated the demand condition from the FA, one that included presession exposure to a preferred item, and another that included presession exposure to preferred items and access to those items during breaks from demands. Although problem behavior occurred in all three demand conditions, within session analyses showed that problem behavior ceased during breaks from demands only when they included access to preferred items. This finding suggests that the motivating operation responsible for evoking problem behavior did not decrease when only a break was provided. Subsequent functional communication training and treatment analysis showed that treatments based on positive reinforcement were effective at reducing problem behavior, but those based on a negative reinforcement hypothesis were not.

Behavior modification of aggressive behavior on a nursery school bus: A case study

A case study is presented in which aggressive behavior of two preschool boys on a nursery school bus was modified by the introduction of a negative punishment contingency in which the Ss were told they would be detained on the bus until the second time the bus passed their house (delay of reinforcement) if abusive behavior occurred. The practical implications of the study and the relative merits of choosing negative punishment over positive punishment as therapy with children are discussed.     

自我损耗对攻击行为的影响:复愈性环境的作用

本研究采用实验(stroop任务和竞争反应时任务)和问卷(积极情感消极情感量表)相结合的方法,探讨复愈性环境对自我损耗后攻击性行为的影响。结果发现:高损耗组反应性攻击行为显著大于低损耗组,两组主动性攻击行为差异不显著;观看复愈性环境和非复愈性环境后,复愈性环境组反应性攻击行为显著低于非复愈性环境组,主动性攻击行为两组无差异。结果表明:自我损耗后会产生情绪上的不良表现,反应性攻击行为增多,而主动性攻击行为不受损耗影响;自我损耗后观看复愈性环境,能够缓解情绪上的不良表现,增加认知资源,从而减少攻击行为。     

A Comparison of Function-Based Differential Reinforcement Interventions for Children Engaging in Disruptive Classroom Behavior

This study provides a direct comparison of differential reinforcement of other behavior (DRO) and differential reinforcement of alternative behavior (DRA). Participants included three children in center-based classrooms referred for functional assessments due to disruptive classroom behavior. Functional assessments included interviews and brief functional analyses. An alternating treatments design was used to evaluate the relative effectiveness of function-based DRO and DRA interventions. Results indicated that both intervention procedures effectively reduced disruptive behavior, but the DRA procedure consistently resulted in greater reductions in disruptive behavior across all participants. Results are discussed in terms of directions for future functional assessment and intervention research as well as implications for applied practice.     

Fixed-ratio schedule-induced aggression

Pigeons' pecks were conditioned with food reinforcement. Subjects were exposed to sessions of no-reinforcement and of fixed-ratio reinforcement. The pigeons attacked a target animal during the fixed-ratio reinforcement conditions. The attack occurred primarily during the post-reinforcement pause and occurred after almost every instance of reinforcement. Little or no aggressive behavior was demonstrated during periods of no-reinforcement except on the initial days of these conditions. The results indicated that a fixed-ratio schedule of reinforcement has certain characteristics capable of producing aggression.     

Angry and aggressive behavior across three generations: a prospective,longitudinal study of parents and children

This investigation examined intergenerational continuities in both angry, aggressive parenting and also the angry, aggressive behavior of children and adolescents. Data from 75 G2 youth (26 men, 49 women, M = 22-years old), their mothers (G1), and their G3 children (47 boys, 28 girls, M = 2.4-years old) were included in the analyses. The prospective, longitudinal design of the study, which included observational and multiinformant measures, overcame many of the methodological limitations found in much of the earlier research on intergenerational transmission. The results demonstrated a direct connection between observed G1 aggressive parenting and observed G2 aggressive parenting from 5 to 7 years later. G2 aggressive behavior as an adolescent and G3 aggressive behavior as a child were related to parenting behavior but not directly to one another. The results were consistent with a social learning perspective on intergenerational continuities in angry and aggressive behaviors.     

Generalization of aggressive behavior in adolescent delinquent boys

The generalization of conditioned aggressive and nonaggressive responses in a group of six adolescent delinquent boys was investigated. Responses were reinforced in card games where a token reinforcement system with money as a back-up rinforcer was used. Conditioning of responses was rapid. Generalization, measured in terms of frequency of physical contact, was tested in a group game for which no reinforcement was given. Generalization occurred during aggressive contingencies. During nonaggressive contingencies, responses did not return completely to the baseline level.     

Brief report: Non-intrusive operant analysis of aggressive behavior in persons with mental retardation

A procedure for operant analysis of aggressive behavior was derived from multi-element assessment methods that have been previously applied to both self-injurious and stereotypic responding. Analog sessions included No Interaction Baseline, Social Disapproval, Demand, Social Reinforcement, and Discriminated Extinction conditions, repeatedly presented within a multi-element design. Three men with differing severity of mental retardation, communicative deficits and aggressive behavior were exposed to multiple brief analog sessions embedded within their normal meal-time routines in group home settings. Mean frequencies of aggressive behavior and concurrent eating indicate that, while aggressive behavior was negatively reinforced in all three participants, both social and non-social contingencies were also prominent. The same contingencies which have been demonstrated to maintain self-injury and stereotypic behavior can therefore also maintain aggression. Results suggest the feasibility of conducting relatively non-intrusive analog assessments in community residences, and support the-extension of functional analysis across differing classes of aberrant behavior.     

Correlates of aggressive and delinquent conduct problems in adolescence

The primary purpose of the study was to test a hypothetical model for aggressive and delinquent conduct problems in adolescence. A total of 168 adolescents from 121 families were studied using several questionnaires and a semi‐structured interview. The following factors were considered: obstetric complications, temperament (novelty‐seeking), self‐esteem, family influences (perceived parenting, alcohol abuse/dependence of parents, antisocial personality disorder of the father) and peer‐group characteristics (peer rejection and membership in a deviant peer group). The evaluation methods applied included correlation analyses and testing of two hypothetical models using structural equation modeling. The correlation analyses revealed significant relationships between adolescent aggressive and delinquent behavioral problems and parental antisocial behavior; perceived parental rejection and low emotional warmth; adolescent novelty‐seeking, self‐esteem, peer rejection and peer deviance. The two empirical models, separately for aggressive and delinquent behavior problems, revealed direct relationships between paternal antisocial behavior, parental rejection, adolescent novelty seeking, peer deviance, peer rejection, and offspring aggression and delinquency. There were, however, two differences with respect to the relationships between peer rejection, peer deviance, aggression and delinquency. First, peer rejection was more strongly associated with aggressive behavior and only moderately linked to delinquency. Second, deviance in the peer‐group was found to be closely related with delinquency but only moderately with aggression. Our findings suggest that several pathways for aggressive and delinquent conduct problems are comparable while others were not. Regarding the findings of the empirical models, we conclude that only intervention measures that include parents, peers and individual adolescents may help decrease the incidence of aggressive and delinquent conduct problems.

Aggressive behavior in the home as a function of the age and sex of control-problem and normal children

This cross-sectional study investigated the ability of age, sex, and clinic-referred or nonreferred status of children to account for variance in the performance of aggressive behavior. Two clinic-referred groups and one normative group of children, composed of 137 males and 86 females between the ages of 3 and 13, were observed during unstructured family interactions in the home setting. Measures of aggressive/aversive child behavior included a composite total aversive behavior (TAB) score, a physical aggression (PAB) score, a verbal aggression (VAB) score, a passive-dependent behavior (PDB) score, and a disobedience (DSB) score. The total regression model and referral status were significant for each of these dependent variables. Age was significant for each variable except VAB, and sex was significant only for PAB. Significant age X group interactions were obtained for TAB, PDB, and DSB. Rates of behavior clearly differentiated groups, but the relationship of age and sex of child to behavior rates was the same across groups. Decreases in all behaviors with increasing age, except for VAB, replicate findings from previous studies in preschool settings. However, the meager sex differences failed to replicate more robust findings generally reported in previous research.     

Instructions and group versus individual reinforcement in modifying disruptive group behavior

Head Start children were matched into two groups on the basis of rates of disruptive behavior during rest periods. Attempts were made to modify their behavior using either individual or group token reinforcement procedures. While the reinforcement procedures reduced inappropriate behavior somewhat, the addition of instructions to the reinforcement reduced the inappropriate behavior to near zero for both groups. Instructions alone, however, were ineffective in controlling behavior. Type of reinforcement (group or individual) did not produce differential effects. While experimental control over the target behavior was demonstrated, there was little carryover from the experimental room to the regular classroom. Even when treatment was introduced into the regular class, follow-up results showed that with time the target behavior approximated pretreatment levels. The results suggest that (a) the combination of instructions and reinforcement is much more effective than either one of these alone, (b) behavior change is specific to the environmental contingencies, and (c) the group reinforcement technique, which is much more easily implemented, was at least as effective as individual reinforcement in the present study.     

Programming for Maintenance: An Investigation of Delayed Intermittent Reinforcement and Common Stimuli to Create Indiscriminable Contingencies

Generalization across time or maintenance of behavior change is a fundamental concern for behavior analysts and educators that remains insufficiently understood. This study examined the maintenance of mathematics responding during and following delayed intermittent reinforcement when common stimuli were programmed across the treatment and maintenance phases. Two third-grade girls who were referred by their classroom teacher due to concerns in the area of mathematics participated. Students were exposed to baseline, contingent reinforcement, delayed intermittent reinforcement, and a maintenance condition. The maintenance condition followed exposure to delayed intermittent reinforcement and included common stimuli from the reinforcement condition, but did not include a contingency for correct responding. Both students exhibited substantial prolonged maintenance during this condition. Implications of these results for future research examining maintenance and applied programming for maintenance are discussed.
