Tobacco use is the leading cause of death globally and in the U.S. After decades of decline, driven by decreases in combusted tobacco use, nicotine product use has increased due to Electronic Nicotine Delivery Systems (ENDS), also known as e-cigarettes or vapes. Preclinical models of nicotine self-administration can serve as important lodestars in...

Delay discounting, the decrease in outcome value as a function of delay to receipt, is an extensive area of research. How delays are framed (i.e., temporal framing), as well as the sign and magnitude of an outcome, produce important effects on the degree to which outcomes are discounted. Here, we examined how recent experience (i.e., order of prese...

The stability of delay discounting across time has been well-established. However, limited research has examined the stabil- ity of probability discounting, and no studies of the stability of effort discounting are available. The present study assessed the steady-state characteristics of delay, probability, and effort discounting tasks across time...

We examined how temporal expectations influence preference reversals in a delay of gratification task for rats based on a hypothesis of Rachlin (2000), who suggested that preference for a larger‐later reward may shift in favor of a smaller‐immediate reward as a result of changes in when that larger reward is expected. To explore Rachlin's hypothesi...

Much research has focused on the development and evolution of cognition in the realm of numerical knowledge in human and nonhuman animals but often fails to take into account ecological realities that, over time, may influence and constrain cognitive abilities in real-life decision-making. Cognitive abilities such as enumerating and timing are cent...

In delay discounting, preference reversals refer to shifts in preference from a larger‐later reward to a smaller‐sooner reward. Steep hyperbolic discounting predicts a preference reversal when a smaller‐sooner and larger‐later reward both become temporally proximal; prior research is consistent with this prediction. Hyperbolic discounting does not...

Delay discounting, the tendency for outcomes to be devalued as they are more temporally remote, has implications as a target for behavioral interventions. Because of these implications, it is important to understand how different states individuals may face, such as deprivation, influence the degree of delay discounting. Both dual systems models an...

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...

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...

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...

Learning strategies are designed to reduce cognitive load and help students organize and integrate important information for later recall; however, students must first select the appropriate information to integrate. Thus, careful development of selection strategies to distinguish between relevant and irrelevant information is necessary for success...

This research examined the impact of a simple feedback model on college-level students' abilities to identify relevant information presented on PowerPoint slides. In Experiment 1 we tested students individually and analyzed how different levels of feedback (general, specific, or no feedback) modified students' abilities to correctly identify releva...

This exploratory analysis examined trends in note taking based on total word counts, relevant and irrelevant word counts, and relevant to total word count ratios (relevance ratios) from a previous study which investigated how the timing of taking notes impacts the encoding and external storage functions of college students' note taking. We performe...

A growing field of research in education examines active learning strategies to find the most successful study strategies for students. Of these, generative learning, an active learning process of physically creating a representation of study material, provokes high-level cognitive processing thereby improving retention. In addition, as age differe...
