Behavioral-momentum

Behavioral momentum theory (BMT) provides a theoretical and methodological framework for understanding how differentially maintained operant responding resists disruption. A common way to test operant resistance involves contingencies with suppressive effects, such as extinction or prefeeding. Other contingencies with known suppressive effects, such as response-cost procedures arranged as point-loss or increases in response force, remain untested as disruptive events within the BMT framework. In the present set of three experiments, responding of humans was maintained by point accumulation programmed according to a multiple variable-interval (VI) VI schedule with different reinforcement rates in either of two components...

The three principles of reinforcement are (1) events such as incentives and reinforcers increase the activity of an organism; (2) that activity is bounded by competition from other responses; and (3) animals approach incentives and their signs, guided by their temporal and physical conditions, together called the "contingencies of reinforcement." Mathematical models of each of these principles comprised mathematical principles of reinforcement (MPR; Killeen, 1994). Over the ensuing decades, MPR was extended to new experimental contexts...

The persistence of operant behavior when disrupted tends to be positively related to how often reinforcers were delivered in the past. Behavioral momentum theory describes this finding as the outcome of Pavlovian processes. That is, the relation between discriminative stimuli and reinforcers that were delivered in their presence strengthens behavior, thereby making it more likely to persist. If only the story were that simple. A growing number of findings challenge the basic tenets of behavioral momentum theory...

Behavioral momentum theory (BMT) suggests that resurgence of destructive behavior may be at least partly determined by the rate of alternative reinforcement, with lean schedules of reinforcement producing less resurgence than dense schedules. Findings from basic and translational studies have been mixed, and the effects of alternative reinforcement rate on resurgence remain unclear. In the current study, we conducted a within-subject evaluation of resurgence during extinction with four children following functional communication training using dense and lean (BMT-informed) schedules of alternative reinforcement...

This study examined the use of the high-probability (high-p) instructional sequence during pre-academic or academic activities for three young children diagnosed with autism spectrum disorder (ASD) served in public elementary schools. Specifically, we examined the effects of the high-p instructional sequence on the children's initiation and completion of low-probability (low-p) instructions, implemented by their classroom teachers. A nonconcurrent multiple-baseline design across participants was used to evaluate the intervention outcomes...

INTRODUCTION: Educators in public schools are required to serve students in their least restrictive environment. While many evidence-based practices (EBPs), defined as practices and strategies shown by research to have meaningful effectson outcomes for autistic students are documented in the literature, less is known about EBP use among educators in public schools. METHODS: Eighty-six general and special education teachers and para educators completed a survey about familiarity, training, and EBP use for included autistic children...

Differential reinforcement of alternative behavior (DRA) involves placing problem behavior under extinction and simultaneously reinforcing a desirable behavior. Recent research revealed that, as predicted by Behavioral Momentum Theory, DRA may also increase the persistence of the problem behavior. This research has also shown that a different approach to DRA, in which an alternative behavior is trained in a separate context from the target behavior, produces less persistence than the standard procedure. The research on this phenomenon, so far, assessed persistence using extinction as the disruptor...

The most important advancement in the treatment of destructive behavior has been the development of the functional analysis, which is used to prescribe effective treatments like functional communication training. Although this approach can be highly effective, extinction bursts and forms of treatment relapse commonly occur when function-based treatments are implemented by caregivers in natural community settings. In recent years, researchers have increasingly applied quantitative theories of behavior like behavioral momentum theory (BMT) and the temporally weighted matching law (TWML) to understand, prevent, or mitigate extinction bursts and treatment relapse...

It has recently been proposed that the intermittent access (IntA) drug self-administration procedure better produces behavioral changes relevant to addiction than the long access (LgA) procedure. In this version of the IntA procedure, the drug is made available for a 5-min period during each half hour of a 6-h session. In contrast, on the LgA procedure, the drug is available continuously for 6 h. Previous studies have found that IntA drug self-administration produces greater drug motivation, measured by increased progressive ratio breakpoints, than LgA self-administration...

Overdose deaths rates caused by psychostimulants have increased by 22.3% annually from 2008 to 2017. Cue-evoked drug craving progressively increases and contributes to perpetual relapse. Preclinical models have determined that glutamate receptor plasticity within the nucleus accumbens (NAc) drives amplified cue-evoked drug-seeking after prolonged abstinence (>40 days). Isolated condition (IC) rearing increases cocaine and amphetamine (AMP) self-administration and cue-induced reinstatement. We tested the hypothesis that housing in the IC will augment AMP-seeking after short and prolonged abstinence from AMP self-administration when compared to rats reared in the enrichment condition (EC)...

Due to the coronavirus (COVID-19) pandemic, around the middle of March 2020, in-clinic intervention services based in applied behavior analysis provided to children had to be stopped abruptly in India. This qualitative and quantitative case study details how Behavior Momentum India (BMI), an organisation providing ABA-based interventions, transitioned services from in clinic to telehealth while continuing to target each student's skill acquisition goals in language and communication domains. A cohort of 92 students diagnosed with autism or other learning disabilities participated in this study; 51 therapists, 9 behavior supervisors, and a doctoral-level Board Certified Behavior Analyst collaborated with parents; 78% of the students and 82% of the therapists used smartphones; and only a few used iPads and laptops...

The hypothesis that response strength might be measured by persistence of responding in the face of extinction was discredited in the 1960s because experiments showed that responding persists longer following intermittent reinforcers than following continuous reinforcers. Instead, researchers proposed that the longer persistence following intermittent reinforcers arises because intermittent reinforcement more closely resembles extinction-a discrimination theory. Attention to resistance to extinction revived because one observation seemed to support the persistence hypothesis: Following training on a multiple schedule with unequal components, responding usually persisted longer in the formerly richer component than in the formerly lean component...

Behavioral Momentum Theory (BMT) is often described as analogous to Newton's (1687) laws of motion. That is to say, similar to an object in motion continuing in motion unless acted upon by a force, responses occurring in a static environment will continue to occur at the same rate, unless presented with a disruptor (Nevin, Tota, Torquato, & Shull, Journal of the Experimental Analysis of Behavior, 53, 359-379, 1990). When evaluating response rates through a behavioral momentum framework, responding continuing after a change in reinforcer conditions is said to persist...

We propose relational density theory, as an integration of stimulus equivalence and behavioral momentum theory, to predict the nonlinearity of equivalence responding of verbal humans. Consistent with Newtonian classical mechanics, the theory posits that equivalence networks will demonstrate the higher order properties of density, volume, and mass. That is, networks containing more relations (volume) that are stronger (density) will be more resistant to change (i.e., contain greater mass; mass = volume * density)...

In the clinic, differential reinforcement of alternative behavior (DRA) often involves programming extinction for destructive behavior while reinforcing an alternative form of communication (e.g., a functional communication response); however, implementing extinction can be unsafe or impractical under some circumstances. Quantitative theories of resurgence (i.e., Behavioral Momentum Theory and Resurgence as Choice) predict differences in the efficacy of treatments that do and do not involve extinction of target responding when reinforcement conditions maintaining alternative responding worsen...

It is widely assumed that reinforcers are biologically relevant stimuli, or stimuli that have been associated with biologically relevant stimuli. However, brief, arbitrary stimuli have also been reported to have reinforcement-like effects, despite being unrelated to biologically relevant stimuli like food. The present study explored the potential reinforcement-like effects of brief stimuli across 5 experiments. In Experiments 1 through 4, pigeon subjects responded for food reinforcement and brief stimulus presentations in a 2-component multiple schedule...

Quantitative models of resurgence (e.g., Behavioral Momentum Theory, Resurgence as Choice) suggest that resurgence is partly a function of the duration of extinction exposure, with longer histories of extinction producing less resurgence. This prediction is supported by some laboratory research and has been partially supported by clinical translations that did not isolate the effects of extinction exposure prior to testing for resurgence. The degree to which different histories of extinction impact the likelihood of treatment relapse in therapeutic applications of differential reinforcement is of great interest to the clinical community, including insurance carriers and other financial providers...

The present experiments assessed whether resistance to extinction of pigeons' key pecking decreased across repeated extinction tests. An additional impetus for this research was to determine how the quantitative framework provided by behavioral momentum theory might be used to describe any such changes across tests. Pigeons pecked keys in two-component multiple schedules (one component associated with a higher reinforcer rate and the other with a lower rate) in which baseline and extinction conditions alternated...

Treatments based on differential reinforcement may inadvertently increase the recurrence of problem behavior in the face of challenges because reinforcers for appropriate behavior occur in the same context as problem behavior. The current study evaluated one potential approach to mitigating these problems with differential reinforcement treatments based on behavioral momentum theory. Specifically, appropriate behavior was trained in contexts without a history of reinforcement prior to intervening with problem behavior...

Resurgence is an increase in a previously suppressed behavior resulting from a worsening in reinforcement conditions for current behavior. Resurgence is often observed following successful treatment of problem behavior with differential reinforcement when reinforcement for an alternative behavior is subsequently omitted or reduced. The efficacy of differential reinforcement has long been conceptualized in terms of quantitative models of choice between concurrent operants (i.e., the matching law). Here, we provide an overview of a novel quantitative model of resurgence called Resurgence as Choice (RaC), which suggests that resurgence results from these same basic choice processes...
