Response Maintenance By Mediated Reinforcement With Forced Alternation Of Reinforcement Opportunities, Kento Yasukawa
Response Maintenance By Mediated Reinforcement With Forced Alternation Of Reinforcement Opportunities, Kento Yasukawa
Graduate Theses, Dissertations, and Problem Reports
Three experiments were conducted to investigate the effects of mediated reinforcement –reinforcers delivered to either of two co-actors by the responses of the other co-actor, but independently of the responses of the co-actor receiving the reinforcer– on the maintenance of responding of the co-actors. In each experiment, using a discrete-trials procedure, responding and receiving reinforcers alternated between co-actors. In Experiment 1, the alternation followed each reinforcer. Also investigated in this experiment were the effects of the presence and absence of social stimuli and of the role of reinforcement delays on individual responding. The number of consecutive reinforcer deliveries to either …
Effects Of Brief-Signal Number And Location On Responding Maintained By Delay Of Reinforcement, Firdavs Khaydarov
Effects Of Brief-Signal Number And Location On Responding Maintained By Delay Of Reinforcement, Firdavs Khaydarov
Graduate Theses, Dissertations, and Problem Reports
The purpose of the present series of experiments was to examine the effects of the number, type, and location of brief signal(s) occurring during, but not throughout, a delay period, on responding maintained by the delay of reinforcement. In each experiment, a tandem variable time (VT) 60-s fixed interval (FI) 9-s schedule was used as a baseline condition of an immediate reinforcement against which delay conditions were examined. For the delay conditions, a chained variable interval (VI) 60-s fixed time (FT) 9-s (delay period) schedule was used, and the imposition of the brief signal (blackout) during the delay period was …
Evaluation Of Renewal During Differential Reinforcement With Asymmetrical Choices And A Context Fading Mitigation Technique, Kacey R. Finch
Evaluation Of Renewal During Differential Reinforcement With Asymmetrical Choices And A Context Fading Mitigation Technique, Kacey R. Finch
Graduate Theses, Dissertations, and Problem Reports
Successful clinical behavior analytic treatment often results in decreases in challenging behavior and increases in appropriate behavior. These reductions in challenging behavior are often achieved by implementing differential reinforcement of alternative behavior (DRA; Petscher et al., 2009). One variation of DRA to decrease challenging behavior is differential reinforcement with asymmetrical choices, which are two or more concurrently available response options associated with differential outcomes (Fisher & Mazur, 1997; Kestner et al., 2023). However, responding that was previously reduced sometimes reemerges. Specifically, renewal is the reemergence of a previously reduced response following a context change. The first two experiments evaluated renewal …
Effects Of Aripiprazole Alone And In Combination With D-Amphetamine On Probability Discounting In Sprague-Dawley Rats, Paige Currie
Effects Of Aripiprazole Alone And In Combination With D-Amphetamine On Probability Discounting In Sprague-Dawley Rats, Paige Currie
Graduate Theses, Dissertations, and Problem Reports
Pharmaceuticals are helpful tools in aiding individuals with psychiatric diagnoses. Sometimes, the drug’s side effects can be more severe than the initial problem. Maladaptive behaviors, like pathological gambling, overeating, and substance abuse, are important to consider during the prescription of different pharmaceuticals, particularly those used to treat Attention-Deficit/Hyperactivity Disorder (ADHD) and autism spectrum disorder (ASD). Individuals with these diagnoses are often prescribed: stimulants, like d-amphetamine (d-AMP; for symptoms associated with ADHD), and antipsychotics, like aripiprazole (ARI; for symptoms associated with ASD). These drugs in combination could influence maladaptive behavior, including risky choice (probability discounting). The present study …
The Effect Of Sequential Stimuli On Variable-Interval Schedule Performance And Resurgence, Amanda K. Miles
The Effect Of Sequential Stimuli On Variable-Interval Schedule Performance And Resurgence, Amanda K. Miles
Graduate Theses, Dissertations, and Problem Reports
Resurgence, or the recurrence of a previously established but not currently occurring response given a worsening of current conditions, is a systematic phenomenon with clinical implications; thus, understanding the variables that impact resurgence is important. Investigations into the impact of discriminative stimuli on resurgence have yielded mixed results about whether the stimuli associated with extinction mitigate or prevent resurgence. The current experiments were conducted with sequential stimuli, that is, two or more stimuli occurring in a fixed sequence, that allowed determination of the effect of discriminative stimuli across a continuum of reinforcement conditions (from most temporally distal to most proximal …
Effects Of Oxycodone And Methylphenidate On Self-Control With Aversive Outcomes, Jeremy Saul Langford
Effects Of Oxycodone And Methylphenidate On Self-Control With Aversive Outcomes, Jeremy Saul Langford
Graduate Theses, Dissertations, and Problem Reports
In the context of choice, one is said to show self-control under numerous conditions in which consideration is given to the delayed outcomes of each option. This can be difficult: both reinforcing and aversive outcomes become less effective as they are increasingly delayed. Several socially significant issues arise from a failure of delayed, aversive outcomes to impact choice, especially when immediate, reinforcing outcomes are available. Identifying the conditions under which choice is sensitive to delayed outcomes is critical to shifting choices toward alternatives in which contact with delayed, aversive outcomes is minimized. Two experiments were conducted with the aim of …
A Monte Carlo Simulation Of Rat Choice Behavior With Interdependent Outcomes, Michelle A. Frankot
A Monte Carlo Simulation Of Rat Choice Behavior With Interdependent Outcomes, Michelle A. Frankot
Graduate Theses, Dissertations, and Problem Reports
Preclinical behavioral neuroscience often uses choice paradigms to capture psychiatric symptoms. In particular, the subfield of operant research produces nested datasets with many discrete choices in a session. The standard analytic practice is to aggregate choice into a continuous variable and analyze using ANOVA or linear regression. However, choice data often have multiple interdependent outcomes of interest, violating an assumption of general linear models. The aim of the current study was to quantify the accuracy of linear mixed-effects regression (LMER) for analyzing data from a 4-choice operant task called the Rodent Gambling Task (RGT), which measures decision-making in the context …
Effects Of Acute And Chronic Nicotine Administration On Choice Of Probabilistic Outcomes, Katya A. Nolder
Effects Of Acute And Chronic Nicotine Administration On Choice Of Probabilistic Outcomes, Katya A. Nolder
Graduate Theses, Dissertations, and Problem Reports
Risky choice can be operationally defined as the choice for a larger, uncertain reinforcer over a smaller, certain reinforcer. Research suggests smokers engage in more risky or maladaptive decisions when compared to nonsmokers. The relation between nicotine and risky choice could benefit from further investigation, since nicotine is the active substance of tobacco products that maintains tobacco addiction. Acute nicotine administration has shown to alter risky choice; however, since the everyday smoker uses nicotine repeatedly, more research on chronic administration is warranted and would allow for assessment of tolerance or sensitization of these effects. The present study investigated effects of …
A Translational Analysis Of Renewal Following Dro With Human Subjects, Kacey R. Finch
A Translational Analysis Of Renewal Following Dro With Human Subjects, Kacey R. Finch
Graduate Theses, Dissertations, and Problem Reports
Renewal is a type of behavioral relapse that is dependent on changes in contextual stimuli in the environment. The current study investigated ABA renewal of responding that had been previously reduced by a differential reinforcement of other behavior (DRO) procedure. ABA renewal refers to the context associated with three phases of behavioral treatment; Context A is present during baseline, Context B is present during treatment, and the post-treatment context returns to Context A (i.e., renewal test). Undergraduate college students participated in a Zoom video call during which they responded by clicking the mouse on a rectangle in a computer program …
Effects Of Nonexamples On Concept Formation, Catherine Louise Williams
Effects Of Nonexamples On Concept Formation, Catherine Louise Williams
Graduate Theses, Dissertations, and Problem Reports
Concept formation is affected by the examples and nonexamples provided during training, but the degree to which examples and nonexamples should differ is unknown. Two experiments compared concept formation when different kinds of nonexamples were used during training. Both experiments included a within-subject comparison of concept formation following three training conditions: a) nonexamples that were more similar to the examples, b) nonexamples that are less similar to the examples, and c) no nonexamples. Arbitrary concepts were trained in Experiment 1 and concepts akin to those that could be taught in a classroom were trained in Experiment 2. Before and after …
An Analysis Of Coordinated Responding, Brian Katz
An Analysis Of Coordinated Responding, Brian Katz
Graduate Theses, Dissertations, and Problem Reports
Experimental analyses of coordinated responding (i.e., cooperation) have been derived from a procedure described by Skinner (1962) in which reinforcers were delivered to a pair of subjects (a dyad) if both responded within a short interval, thus satisfying a mutual-reinforcement contingency. Although it has been suggested that this contingency enhances rates of temporally coordinated responding, limitations of past experiments have raised questions concerning this conclusion. The present experiments assessed three of those limitations by holding the schedule of reinforcement (Experiment 1: fixed-ratio 1; Experiment 2; variable-interval 20 s) constant (1) across phases and (2) between dyad members, and (3) varying …
Comparing Common Procedures Used To Manipulate Reinforcer Magnitude, Michael Steele Yencha
Comparing Common Procedures Used To Manipulate Reinforcer Magnitude, Michael Steele Yencha
Graduate Theses, Dissertations, and Problem Reports
Reinforcer magnitude is one of several parameters of reinforcement. In the present study, it referred to the quantitative value of the reinforcer in terms of duration of access to a finite supply of grain pellets. Pigeons responded on concurrent-chain schedules earning one of several reinforcer durations depending on response allocation and experimental conditions. Experiment 1 consisted of relatively long reinforcer durations available for completing one chain compared to relatively short durations available on the other. Response allocation in the initial link determined the reinforcer duration, but responses in the terminal link produced no change in the upcoming reinforcer. This arrangement …
Effects Of Blended Integrity Failures On Reinforcement-Based Interventuions, Stephanie Hope Jones
Effects Of Blended Integrity Failures On Reinforcement-Based Interventuions, Stephanie Hope Jones
Graduate Theses, Dissertations, and Problem Reports
Reinforcement-based interventions reduce problematic behavior when implemented as designed. However, the effectiveness of these interventions may decrease when deviations from treatment protocols (i.e., treatment-integrity errors) occur. Treatment-integrity errors differentially impact reinforcement-based interventions based on multiple factors, including how frequently errors occur and the intervention type. Even nominally acceptable integrity values (e.g., 80%) may be detrimental depending on the intervention. To evaluate this possibility and directly compare the effectiveness of multiple reinforcement-based interventions, we conducted two within-subject evaluations using laboratory arrangements. For both experiments, we recruited four undergraduate students to participate in a computer task that involved clicking on moving circles …
Chlordiazepoxide Increases Risky Choice, Devin Andrew Galdieri
Chlordiazepoxide Increases Risky Choice, Devin Andrew Galdieri
Graduate Theses, Dissertations, and Problem Reports
Probability discounting is a measure of risky choice that is correlated with maladaptive behavior and psychological disorders. Benzodiazepines are a class of drug on which relatively little risky-choice research has been conducted, particularly under conditions of chronic drug exposure. Chlordiazepoxide, a standard benzodiazepine, was administered to rats that had been trained to respond on a risky-choice task in which a choice was available between a single food pellet with 100% certainty or three food pellets with probabilities of delivery that decreased across each experimental session. During baseline, responding was sensitive to the programmed contingencies and larger-reinforcer choice decreased as the …
Behavioral Functions Of Stimuli Correlated With Transitions Between Rich And Lean Schedules Of Reinforcement, Cory Whirtley
Behavioral Functions Of Stimuli Correlated With Transitions Between Rich And Lean Schedules Of Reinforcement, Cory Whirtley
Graduate Theses, Dissertations, and Problem Reports
Disruptions in operant behavior in the form of extended pausing reliably occur when there is a discriminable transition from a relatively rich schedule of reinforcement to a relatively lean schedule (i.e., a rich-lean transition). The present experiments assessed the reinforcing and aversive functions of the stimuli correlated with the transitions between rich and lean schedules using observing and escape procedures. In both experiments, pigeons’ key pecks were reinforced with food on a compound schedule with two FR components. Completing the FR in the rich component produced a large reinforcer; completing the FR in the lean component produced a small reinforcer. …
Effects Of Teacher Training In Trial-Based Functional Analysis Via Video Modeling, Mary Haspel
Effects Of Teacher Training In Trial-Based Functional Analysis Via Video Modeling, Mary Haspel
Graduate Theses, Dissertations, and Problem Reports
Trial-based functional analysis (TBFA) is an efficient strategy for assessing challenging behavior in the classroom and a necessary step in developing effective functional assessment- based interventions (FABI). However, researchers have identified several barriers limiting the applicability of this practice in schools, including difficulty in (a) training teachers to mastery; (b) assessing whether teachers can implement this practice independently, with fidelity, in natural settings; and (c) determining whether teachers can use functional analysis (FA) to identify functions of problem behavior and develop effective interventions. This study will address these gaps in the literature by using a novel approach for training teachers …
Resurgence Of Academic Responses, Catherine Louise Stephens
Resurgence Of Academic Responses, Catherine Louise Stephens
Graduate Theses, Dissertations, and Problem Reports
Resurgence is the recurrence of a previously reinforced response after a more recently reinforced response is placed on extinction. Resurgence may explain the recurrence of socially appropriate behavior, including academic responding, but this had not yet been empirically demonstrated. The aim of this study was to determine if resurgence would occur when a participant solved quadratic equations using multiple methods. Each participant was taught two methods of solving quadratic equations across experimental phases, followed by a phase in which neither method resulted in the correct solution. In the first phase, only simple factoring was reinforced. In the second phase, only …
Behavioral Impairment Following Gestational Exposure To Titanium Dioxide Nanomaterial Aerosols In Male And Female Rats, Matthew Leland Eckard
Behavioral Impairment Following Gestational Exposure To Titanium Dioxide Nanomaterial Aerosols In Male And Female Rats, Matthew Leland Eckard
Graduate Theses, Dissertations, and Problem Reports
Engineered nanomaterials (ENMs) are beginning to be recognized as hazardous to human and animal health. Titanium dioxide (TiO2) is primarily used as a whitening agent in paints, plastics, and sunscreens. While relatively inert in its bulk form, nano-TiO2 (diameter) can produce prolonged inflammation and oxidative stress in target tissue. Recently, the potential for nano-TiO2 to cause neuroinflammation and damage has heightened concerns about its continued use. One important concern is that nano-TiO2, and other metal oxide ENMs, may affect fetal neurodevelopment. Accordingly, it is imperative to screen ENMs, like TiO2, for possible neurotoxicity following developmental exposures. The current set of …
Mirror, Mirror In The Chamber: Effects Of Social Stimuli On Operant Behavior, Michael Steele Yencha
Mirror, Mirror In The Chamber: Effects Of Social Stimuli On Operant Behavior, Michael Steele Yencha
Graduate Theses, Dissertations, and Problem Reports
The variables affecting social behavior are myriad, making the prediction and control of behavior occurring in social contexts relatively difficult. One can attempt to create a controlled social context in the laboratory by introducing a second organism into an operant chamber. To investigate effects of social stimuli on operant responding, key pecking responses of three pigeons were maintained on a variable-interval (VI) schedule of reinforcement in Experiment 1, and the key pecking responses of three additional pigeons were maintained on a three-component multiple schedule in Experiment 2. The components included a variable-ratio (VR) schedule, a fixed-interval (FI) schedule, and a …
Determinants Of Control-Key Responding In An Operant Resurgence Procedure, Anthony C. Oliver
Determinants Of Control-Key Responding In An Operant Resurgence Procedure, Anthony C. Oliver
Graduate Theses, Dissertations, and Problem Reports
The Control response in a resurgence procedure has been described as the “gold standard” in isolating resurgence from other extinction-induced phenomena. Although Control responding is not generally observed during the resurgence test phase of animal-resurgence procedures, it is common to see such responding in human-operant resurgence procedures. Thus, it is necessary to identify the conditions under which Control responding may be observed. Using pigeons and rats as subjects, the current series of experiments examined the determinants of Control-operandum responding in a resurgence procedure. Experiment 1 assessed whether behavior with a pre-experimental reinforcement history would resurge if the Target response was …
Probability Discounting Of Lewis And Fischer 344 Rats: Strain Comparisons At Baseline And Following Acute Administration Of D-Amphetamine, Jenny E. Ozga
Graduate Theses, Dissertations, and Problem Reports
Risky choice can be defined as choice for a larger, uncertain reinforcer over a smaller, certain reinforcer when choosing the smaller alternative maximizes reinforcement. Risky choice is studied using various procedures in the animal laboratory; one such procedure is called probability discounting. There are many variables that contribute to risky decision-making, including biological and pharmacological determinants. The present study assessed both of these variables by evaluating dose-response effects of d-amphetamine on risky choice of Lewis (LEW) and Fischer 344 (F344) rats. The probability-discounting procedure included discrete-trials choices between one food pellet delivered 100% of the time and three food …
Delay Discounting And Cannabinoid Enzyme Inhibitors, Devin Andrew Galdieri
Delay Discounting And Cannabinoid Enzyme Inhibitors, Devin Andrew Galdieri
Graduate Theses, Dissertations, and Problem Reports
Delay discounting is a measure of impulsive choice that is correlated with maladaptive behavior and psychological disorders. Disruptions to serotonin and dopamine pathways can cause changes in delay discounting, as can lesions to the prefrontal cortex and nucleus accumbens. The endocannabinoid system modulates other neurotransmitter systems, including dopamine and serotonin pathways. Cannabinoid receptors type 1 are found in relatively high concentrations in the nucleus accumbens and the prefrontal cortex. These receptors are activated by endogenous cannabinoids, which are synthesized on demand and broken down by catabolic enzymes. The action of these enzymes can be inhibited by a class of drugs …
Effects Of Delay And Signals On Choice Between Delayed Food Alone And Immediate Food With Delayed Shock, Forrest James Toegel
Effects Of Delay And Signals On Choice Between Delayed Food Alone And Immediate Food With Delayed Shock, Forrest James Toegel
Graduate Theses, Dissertations, and Problem Reports
Much of the research in the area of self-control has examined choice between small immediate reinforcers and large delayed reinforcers, but many problems result from situations in which a single choice produces consequences of conflicting valence: Those in which the immediate outcome is reinforcing and the delayed outcome is aversive. Recent research has evaluated how preference for a large reinforcer which is followed by a delayed shock changes as a function of the delay to shock and how the intensity and duration of delayed shock affects the value of a large reinforcer. The present set of experiments investigated how the …
Effects Of Reinforcement Rate On The Aversive Function Of Timeout From Positive Reinforcement, Cory Whirtley
Effects Of Reinforcement Rate On The Aversive Function Of Timeout From Positive Reinforcement, Cory Whirtley
Graduate Theses, Dissertations, and Problem Reports
Although the use of timeout from positive reinforcement is widespread and has been shown to be an effective punisher in clinical settings, the factors responsible for its effectiveness are not fully understood. The present experiment was designed to evaluate one of these factors, the reinforcement rate underway during periods of time-in. Rats’ lever pressing was maintained on variable-interval schedules of food reinforcement in a multiple schedule with two components. In one component, no timeouts were delivered. In the other component, when a variable-ratio schedule was met, lever presses were followed by a 30-s timeout during which a tone sounded, the …
