THE USE OF PEER MONITORS TO REDUCE NEGATIVE INTERACTION DURING RECESS

The negative interactions of a mildly retarded child, Dennis, were reduced in three daily recess periods, withthe use of a point system. Adult monitors initiatedthe intervention inthe morning recess; reductions achieved during adult monitoring were maintained in that recess during two subsequent conditions: peer monitoring and self-monitoring. Dennis' negative interactions were reduced next inthe afternoon recess by peer monitors. Again, reductions were maintained during a subsequent self-monitoring condition. Finally, duringthe noon recess, Dennis was trained to serve as a peer monitor for Ed, a moderately retarded classmate. Dennis' rate of negative interactions quickly decreased following his appointment as a peer monitor. The results show that a point system, originally designed for adult monitoring, can be adapted without loss of program effectiveness for peer monitoring or self-monitoring. The results also suggest that classmates who serve as peer monitors may benefit significantly from their role. The conditions under which these therapeutic effects occur andthe role that treatment order effects may play in this process require further investigation.     

Observing behavior in a computer game.

Contingencies studied in lever-pressing procedures were incorporated into a popular computer game, "Star Trek," played by college students. One putative reinforcer, the opportunity to destroy Klingon invaders, was scheduled independently of responding according to a variable-time schedule that alternated unpredictably with equal periods of Klingon unavailability (mixed variable time, extinction schedule of reinforcement). Two commands ("observing responses") each produced stimuli that were either correlated or uncorrelated with the two components. In several variations of the basic game, an S-, or bad news, was not as reinforcing as an S+, or good news. In addition, in other conditions for the same subjects observing responses were not maintained better by bad news than by an uninformative stimulus. In both choices, more observing tended to be maintained by an S- for response-independent Klingons when its information could be (and was) used to advantage with respect to other types of reinforcement in the situation (Parts 1 and 2) than when the information could not be so used (Part 3). The findings favor the conditioned reinforcement hypothesis of observing behavior over the uncertainty-reduction hypothesis. This extends research to a more natural setting and to multialternative concurrent schedules of events of seemingly intrinsic value.     

Computer-assisted observer training

Computerized interactive videotapes were used to train college students to use a 10-second partial-interval observational recording system. Students viewed videotapes and scored response occurrences on a computer keyboard. Incorrect scoring resulted in immediate computerized feedback and rescoring.     

ESCAPE AS A FACTOR IN THE AGGRESSIVE BEHAVIOR OF TWO RETARDED CHILDREN

This study sought to identify some of the variables controlling the severely aggressive behavior of two retarded children. In Experiment 1, each child was presented with several demand and nondemand situations. Aggression was frequent in the demand situations and rare in the nondemand situations. When a stimulus correlated with the termination of demands was introduced, aggression fell to a near zero level. In Experiment 2, for one child, a variety of preferred reinforcers was introduced into the demand situation contingent on correct responding. Aggression abruptly decreased to a low level. Experiments 3 and 4 involved the second child. In Experiment 3, this child was permitted, in one condition, to leave the demand situation if he emitted a nonaggressive response. Aggression decreased to a low level. In Experiment 4, he was prevented, in one condition, from leaving the demand situation in spite of high levels of aggression. Aggression fell to a near zero level. In Experiments 3 and 4, he was permitted, in several conditions, to leave the demand situation following aggressive behavior. Aggression increased to a high level. The results suggested that: (1) aggression can sometimes function as an escape response; and (2) escape-motivated aggression can be controlled by: (a) introducing strongly preferred reinforcers to attenuate the aversiveness of the demand situation; (b) strengthening an alternative, nonaggressive escape response; or (c) using an escape-extinction procedure.     

Teacher escape,avoidance, and countercontrol behaviors: Potential resoponses to disruptive and aggressive behaviors of students with severe behavior disorders

We develop hypothese based on the research literature regarding behavioral responses to aversive stimuli. Specifically, escape, avoidance, and countercontrol responses are presented as teacher behaviors which may occur in the presence of disruptive and aggressive behaviors (aversive stimuli) which, in part, characterize many students with severe behavior disorders (SBD). The potential for teacher escape, avoidance, and countercontrol responses to the detrimental for both teachers and students is presented, as well as suggestions for addressing aversive behaviors of students in ways to reduce the potential detrimental impact.     

Power on the margins: A new place for intellectuals to be

This paper is concerned with rethinking the nature of social life in terms of how it appears — not to us academics at the centre of it, as consisting in a system, or a plurality of systems -but how it might appear from a position more in on the margins, at those moments when ordinary people must relate themselves to each other, unsystematically and practically. To do this, we must also rethink the nature of language and thought as possessing within these moments, a formative or creative character — for it must have the ability to create practical connections between aspects of people's lives, as required, on the spot. This is to privilege the role of rhetoric in these regions over that of logic. This also leads to a rethinking of ideology and power: as being to do with, not ideas, but the practical shaping (or not) — in moments when in practical communication with others — of collective, sharable forms of life. Where it is in such moments, in which different people meet each other in socially constructing their lives together, that political struggles are their most intense, and where ideology can be detected at work.     

Types of aggressive behavior among aggressive-preferred, aggressive non-preferred, non-aggressive preferred and non-aggressive non-preferred 14-year-old adolescents

This study examined differences in the types of aggressive behavior among aggressive-preferred, aggressive non-preferred, non-aggressive preferred and non-aggressive non-preferred adolescents. The subjects numbered 839 14-year-old adolescents (408 girls and 431 boys). Aggressive behavior as well as social preference i.e. popularity and rejection, were assessed by peer nominations. The types of aggressive behavior measured were intriguing, arguing, fighting and bullying. The results showed that not only the level, but also the types of aggressive behavior differentiated aggressive adolescents from the non-aggressive ones, and preferred adolescents from the non-preferred ones. The aggression profile of the aggressive and rejected adolescents was characterized more by intriguing and bullying than arguing or fighting. In contrast, that of non-aggressive adolescents was dominated more by arguing and fighting than intriguing. The results pointed to a more complex relationship between aggressive behavior and social preference than the general assumption that there is a higher rate of rejection among aggressive adolescents, and a higher rate of popularity among non-aggressive ones. Significant gender differences were also found.     

Motion as a natural category for pigeons: Generalization and a feature-positive effect

Three groups of pigeons were trained with a modified discriminative autoshaping procedure to discriminate video images of other pigeons on the basis of movement. Birds of all groups were shown the same video images of other pigeons, which were either moving or still. The group to whom food was presented only after moving images learned the discrimination very quickly. A second group, to whom food was given only after still images, and a pseudocategory group, to whom food was presented after arbitrarily chosen stimuli, showed no evidence of discrimination during acquisition training. Extinction conditions led to clear differences in peck rates to moving and still images in the second group but not in the pseudocategory group. The result is related to the feature-positive effect. Generalization tests showed that the discrimination performance was based on visual features of the stimuli but was invariant against changes of size, perspective, brightness, and color. Furthermore, discrimination was maintained when novel images of pigeons under different viewing angles and seven other types of motion categories were presented. It is argued that the discrimination is based not on a common motion feature but on motion concepts or high-order generalization across motion categories.     

Interpersonal Skills Training to Reduce Aggressive and Delinquent Behavior: Limited Evidence and the Need for an Evidence-Based System of Care

The prevention of aggressive and delinquent behavior during childhood and adolescence is one of the highest priorities for public health and crime prevention. The most common approach to preventing or treating these conduct problems has been to provide interpersonal skills training to the affected youth. This paper reviews all randomized controlled trials evaluating interpersonal skills training programs as an intervention to reduce conduct problems. Research shows that such programs have weak empirical support as isolated interventions. An alternative evidence-based system of care is described. Such a system would include behavioral parent training and behavioral classroom-based interventions for young children at risk of developing problems, as well as multisystemic family therapy or multidimensional treatment foster care for chronic delinquents. Within such a network of services, interpersonal skills training could play an important supportive role. Such a system holds the greatest promise for reducing the prevalence of aggressive and delinquent behavior in communities.
