EFFECTS OF REINFORCER QUALITY ON BEHAVIORAL MOMENTUM: COORDINATED APPLIED AND BASIC RESEARCH

The high-probability (high-p) instructional sequence has been an effective treatment for noncompliance. However, treatment failures have also been reported. We hypothesized that the efficacy of the high-p treatment may be improved by using higher quality reinforcers for compliance to high-p instructions. The resistance of compliance to change was tested by varying reinforcer quality in two applied studies and a basic laboratory experiment. Experiment 1 tested the hypothesis that an increase in reinforcer quality for high-p compliance will increase the effectiveness of the high-p treatment when it fails to increase compliance. Experiment 2 assessed the effects of reinforcer quality on resistance of compliance to change by presenting successive low-p requests following the high-p treatment. A basic laboratory study (Experiment 3) was conducted to further isolate the relation between reinforcer quality and behavioral momentum. Two different liquid reinforcers (sucrose and citric acid solutions) were presented in a two-component multiple variable-interval variable-interval schedule followed by a single extinction test session. Results of all three experiments showed a generally consistent relationship between reinforcer quality and behavioral momentum.     

Behavioral momentum in college basketball

Three classes of events were scored from videotapes of 14 college basketball games during the 1989 National Collegiate Athletic Association tournament: reinforcers (such as points and favorable turnovers), adversities (such as missed shots, unfavorable turnovers, and fouls), and responses to adversities (favorable or unfavorable outcomes of the first possession of the ball following an adversity). Within-game and within-team analyses of these data supported three findings. First, a team's favorable response to an adversity generally increased as the rate of reinforcement increased 3 min preceding the adversity. Second, basketball coaches called time-out from play when being outscored by their opponents an average of 2.63 to 1.0. Third, calling time-outs from play appeared to be an effective intervention for reducing an opponent's rate of reinforcement. Rates of reinforcement during the 3 min immediately after a time-out were nearly equal for both teams. Results are discussed within a behavioral momentum framework.     

Reductions in shock frequency and response effort as factors in reinforcement by timeout from avoidance

Rats' presses on one lever canceled shocks programmed after variable cycles, while presses on a second lever occasionally produced a 2-min timout during which the shock-delection schedule was suspended and its correlated stimuli removed. These concurrent schedules of avoidance and timeout were embedded in a multiple schedule whose components differed, within and across conditions, in terms of the programmed shock rate associated with the shock-deletion schedule. Analyses based on the generalized matching law suggest that the reduction in the response requirement correlated with termination of the avoidance schedule was a more important factor in the reinforcing effectiveness of timeout than was shock-frequency reduction, at least in 2 of 3 rats. After training in each condition, responding on the timeout lever was extinguished by withholding timeouts in both components over seven sessions. Resistance to extinction varied directly with the rates of both shock-frequency reduction and avoidance-response reduction experienced during training. Although reduction in response effort appeared to dominate shock-frequency reduction in the maintenance of responding, neither factor had a clear advantage in predicting the course of extinction.     

An integrative model for the study of behavioral momentum.

Behavioral momentum is the product of response rate and resistance to change. The data on relative resistance to change are summarized for pigeons responding on single-key two-component multiple schedules, in the initial links of two-key multiple chained schedules, and in equivalent components of two-key serial schedules. For single-key procedures, the ratio of resistance to change in two schedule components is shown to depend on the ratio of reinforcer rates obtained in the presence of the component stimuli. For two-key procedures, the ratio of resistance to change in equivalent components is shown to depend on the ratio of reinforcer rates correlated with key locations. A model based on stimulus-reinforcer contingencies that combines the reinforcer rates in schedule components summed over key locations and reinforcer rates correlated with key locations summed over components, each expressed relative to the session average reinforcer rate, gives a good account of the data. An extension of the relative law of effect for multiple schedules fails to provide a complete account of resistance to change, but both approaches are needed for a comprehensive understanding of behavioral momentum.     

Pavlovian contingencies and resistance to change in a multiple schedule

According to theoretical accounts of behavioral momentum, the Pavlovian stimulus—reinforcer contingency determines resistance to change. To assess this prediction, 8 pigeons were exposed to an unsignaled delay-of-reinforcement schedule (a tandem variable-interval fixed-time schedule), a signaled delay-of-reinforcement schedule (a chain variable-interval fixed-time schedule), and an immediate, zero-delay schedule of reinforcement in a three-component multiple schedule. The unsignaled delay and signaled delay schedules employed equal fixed-time delays, with the only difference being a stimulus change in the signaled delay schedule. Overall rates of reinforcement were equated for the three schedules. The Pavlovian contingency was identical for the unsignaled and immediate schedules, and response—reinforcer contiguity was degraded for the unsignaled schedule. Results from two disruption procedures (prefeeding subjects prior to experimental sessions and adding a variable-time schedule to timeout periods separating baseline components) demonstrated that response—reinforcer contiguity does play a role in determining resistance to change. The results from the extinction manipulation were not as clear. Responding in the unsignaled delay component was consistently less resistant to change than was responding in both the immediate and presignaled segments of the signaled delay components, contrary to the view that Pavlovian contingencies determine resistance to change. Probe tests further supported the resistance-to-change results, indicating consistency between resistance to change and preference, both of which are putative measures of response strength.     

Refraining Resistance and Noncompliance in Cognitive Therapy

Despite its general success, not everyone responds to cognitive therapy. Some clients have difficulty complying with assignments and others appear to be frankly resistant. This article considers strategies for dealing with passive noncompliance and active resistance within cognitive therapy. In general, it is argued that the process of therapy is usually facilitated by staying within the cognitive model—that is, by exploring and working through those beliefs and attitudes that underlie noncompliance and resistance in the same manner that other problematic beliefs and attitudes are approached. Also considered are strategies for dealing with unrealistic expectations regarding the pace of change, therapists' errors leading to noncompliance and resistance, and instances in which the therapeutic model is simply insufficient.     

Article for “Diversity Stories in Community Research and Action” Facing Resistance in Waking Up to Privilege

In 1994, out of a population of 45 million people an estimated 7.7 million people lived in informal settlements in South Africa (South African Institute of Race Relations, 1994). This article focuses on one community whose residents' desperation to own housing contributed to community disintegration, typified by infighting among women, and threats to human life. Issues of diversity became more prominent and destabilized community-building efforts. One effort to collaboratively break down barriers that deterred women from working together is presented to illustrate how these women created bonds based on "discovered similarities." The participatory and personal-experience approach described here contributed to their becoming active protagonists of their learning and encouraged tolerance and understanding among community women from differing ethnic, linguistic, and political backgrounds. The article concludes with a discussion of the critical importance of recognizing and working with and through differences within the current South African reality.     

Fifty years on: a training for the 21 century, from couple to community

The paper describes the gradual transformation of the structures, process and content of the adult training at the Society of Analytical Psychology (SAP) from 1997 when the potential for individuation had gone awry through lack of a culturally relevant and coherent programme until 2005 when trainees' professional and personal individuation could be enhanced by a process and a curriculum representing fairly the interests and beliefs of the range of different approaches to Jungian psychology that are to be found in the SAP. The process has taken eight years to complete and in the paper, the authors, two successive Directors of Training, describe the persistent resistances to necessary change from within their Society, focusing in particular on the key role of the founder member; the privileging of the internal world at the expense of significant external factors; a confusion of roles among members between volunteers and professionals and last, but by no means least, the contamination of the educative task and the creation of a training community by fantasies of the mother/infant couple.     

Racial reckoning,resistance, and the revolution: A call to community psychology to move forward

This article introduces a special issue of the American Journal of Community Psychology that features racial reckoning, resistance and the revolution in the context of a syndemic, the historical subjugation of communities of Color (COC) to racial hierarchies and the coronavirus (COVID-19). More specifically, this special issue underscores the need for community psychology and other allied disciplines to address this syndemic facing COC. The special issue delivers on the stories of the lived experiences from researchers and community members as it relates to COVID-19 and COC. Twelve articles are illuminated to challenge the field to create social change.     

RESPONDING MAINTAINED BY INTERMITTENT REINFORCEMENT: IMPLICATIONS FOR THE USE OF EXTINCTION WITH PROBLEM BEHAVIOR IN CLINICAL SETTINGS

Results of basic research have demonstrated that behavior maintained on an intermittent schedule of reinforcement (INT) will be extinguished more slowly than behavior maintained on a continuous schedule (CRF). Although these findings suggest that problem behaviors may be difficult to treat with extinction if they have been maintained on INT rather than on CRF schedules, few applied studies have examined this phenomenon with human behavior in clinical settings. The purpose of this study was to determine whether problem behavior maintained on CRF schedules would be extinguished more rapidly than behavior maintained on INT schedules. Three individuals diagnosed with profound mental retardation participated after results of pretreatment functional analyses had identified the sources of reinforcement that were maintaining their self-injury, aggression, or disruption. Subjects were exposed to extinction following baseline conditions with CRF or INT schedules alternated within reversal or multielement designs. Results suggested that problem behaviors may not be more difficult to treat with extinction if they have been maintained on INT rather than CRF schedules. However, switching from an INT to a CRF schedule prior to extinction may lower the baseline response rate as well as the total number of responses exhibited during extinction.
