Individuals diagnosed with autism spectrum disorder (ASD) tend to display restricted, repetitive behaviors and deficits in social interaction. Rats exposed to valproate (VPA) in utero have been shown to model symptoms of ASD. In previous research, VPA rats engaged in less social interaction and more repetitive responding than controls. The purpose...
Group-based experimental designs are an outgrowth of the logic of null-hypothesis significance testing and thus, statistical tests are often considered inappropriate for single-case experimental designs. Behavior analysts have recently been more supportive of efforts to include appropriate statistical analysis techniques to evaluate single-case exp...
Delay discounting is the loss in value of an outcome as a function of its delay. The present study focused on examining a trait-like characteristic of delay discounting in a preclinical animal model. Specifically, we were interested in whether there was a positive relation between discounting of 2 different outcomes in rats. That is, would rats tha...
The present study examined resurgence of reinforced variability in college students, who completed a 3‐phase computer‐based variability task. In the first phase, baseline, points were delivered for drawing rectangles that sufficiently differed from previous rectangles in terms of a target dimension (size or location, counterbalanced) but were suffi...
Delay discounting is the process by which a commodity loses value as the delay to its receipt increases. Rapid discounting predicts various maladaptive behaviors including tobacco use. Typically, delay discounting of different outcomes has been compared between cigarette smokers and nonsmokers. To better understand the relationship of delay discoun...
Although individuals with autism spectrum disorder (ASD) tend to behave repetitively, certain reinforcement contingencies (e.g., lag schedules) can be used to increase behavioral variability. In a lag schedule, reinforcers only follow responses that differ from recent responses. The present study was designed to promote variable play behavior in pr...
Steep delay discounting is characterized by a preference for small immediate outcomes relative to larger delayed outcomes and is predictive of drug abuse, risky sexual behaviors, and other maladaptive behaviors. Nancy M. Petry was a pioneer in delay discounting research who demonstrated that people discount delayed monetary gains less steeply than...
Relapse is the recovery of a previously suppressed response. Animal models have been useful in examining the mechanisms underlying relapse (e.g., reinstatement, renewal, reacquisition, resurgence). However, there are several challenges to analyzing relapse data using traditional approaches. For example, null hypothesis significance testing is commo...
We examined the effects of outcome framing on delay discounting. In Experiment 1, participants completed four delay‐discounting tasks. In one monetary task, money was framed in units of dollars ($50), and in the other, money was framed in units of handfuls of quarters (equal to $50). In one food task, food was framed in clear units of food (e.g., 1...
Alcohol is the most commonly abused drug in the USA and many people suffer from alcohol use disorder. Many factors are associated with alcohol use disorder, but the causal role of comorbid nicotine use has not been extensively considered. Nicotine has reward-enhancing properties and may increase the value of alcohol. Monoamine oxidase inhibition in...
Alcohol is the most commonly used drug in the United States and alcohol abuse can lead to alcohol use disorder. Alcohol use disorder is a persistent condition and relapse rates following successful remission are high. Many factors have been associated with relapse for alcohol use disorder, but identification of these factors has not been well trans...
In the supporting information file, there are 7 columns.
The first column is group assignment. The second column is subject ID. The third column is phase. The fourth column is session number. The fifth column is total grams of alcohol drunk during the session. The sixth column is grams of alcohol drunk per kilogram in the session. The seventh colum...
The present study examined persistence and relapse of reinforced behavioral variability in pigeons. Pigeons emitted four-response sequences across two keys. Sequences produced food according to a lag schedule, in which a response sequence was followed by food if it differed from a certain number of previous sequences. In Experiment 1, food was deli...
Following training with verbal stimulus relations involving A is greater than B and B is greater than C, verbally-competent individuals reliably select A > C when asked “which is greater, A or C?” (i.e., verbal transitive inference). This result is easy to interpret. Nonhuman animals and humans with and without intellectual disabilities have been e...
Delay discounting refers to a decline in the value of a reward when it is delayed relative to when it is immediately available. Delay discounting tasks are used to identify indifference points, which reflect equal preference for two dichotomous reward alternatives differing in both delay and magnitude. Indifference points are key to assessing the s...
There is disagreement about how to characterize the environment-behavior relations involved in the reinforcement of behavioral variability. The present research examined some of these issues using food-maintained, 4-peck sequences in pigeons. Experiment 1 evaluated the claim that behavioral variability is not reinforced directly but, rather, is the...
Objectives:
Physiological reactivity (PR) describes the change in physiological functioning (e.g., heart rate, blood pressure, pulse pressure) that occurs after the induction of a stressful task. This study aims to understand the influence of mental health symptoms on patterns of PR during autobiographical narratives in an older adult sample.
