Effects of Acute Vaping Abstinence on Hyper-palatable Food Reinforcement and Intake
… tend to increase consumption of hyper-palatable foods (HPF) following cessation of combustible tobacco use (i.e., smoking). Although conceptually relevant, it is unclear how cessation of electronic nicotine delivery systems (ENDS) may affect HPF intake. Cessation- related increases in HPF intake …

Relationships between food reinforcement and eating behaviors to bariatric surgery weight loss and substance abuse outcomes
… between the relative reinforcing value of food (RRV-F), delay discounting for food (DD-F), and other eating-related and non eating-related variables to post-bariatric surgery percent total weight loss (%TWL) and substance-related outcomes. Participants were a convenience sample of 147 …

Effects of Deprivation and Testing Procedures on Preference for Stimuli Correlated with Food Reinforcement Under Higher Deprivation Conditions in Mice
… appear to prefer stimuli correlated with food reinforcement under higher food deprivation levels relative to stimuli correlated with food under lower deprivation levels. This has led some researchers to assume a general relation between food deprivation level and preference regardless of …

The Relative Efficiency of Auditory (Social) Reinforcement vs. Food Reinforcement with the Squirrel Monkey (Saimiri Sciureus) in an Operant Situation
Research using non-deprivation and sensory or food reinforcement has received little attention to the present time. It is possible that, at least in the laboratory, sensory reinforcement under non- deprived conditions may be a much more economical and efficient reinforcer than food reinforcement …

Influence of a High-Fat Diet on Delay Discounting, Food Reinforcement, and Eating Behaviors in Sedentary and Endurance Trained Men
People make food choices based upon the motivation to consume foods that are reinforcing compared to alternatives that may be available.1 Delay discounting (DD) is a measure used to assess impulsivity, quantifying how people make decisions based on time to receive and amount of the choice …

The Nosological Status of Loss of Control over Eating in Children
… Another obesogenic appetitive trait, high food reinforcement, is characterized by a strong drive to obtain palatable food. LOC and high food reinforcement both predict increased energy intake and excessive weight gain, although the association between LOC and high food reinforcement has not …

Affective responses to environmental influences in immature rats
… a day, to run a runway for different amounts of food reinforcement. He then measured their resulting running speeds. He was able to show that the rats ran at speeds that were proportional to the amount of food reinforcement that they received. As part of the same group of experiments, Crespi pre …

Delay Discounting, Reinforcing Value of Food, and Components of Metabolic Health
… behaviors, such as body weight management, food intake, glucose control, and physical activity. While a number of studies have concluded that obese individuals tend to be greater discounters, the relationship between delay discounting and various health-related behaviors beyond smoking and …

Acquisition of observing responses with delayed conditioned reinforcement
… response) on a tandem fixed-ratio 1 differential-reinforcement-of-other-behavior 10-s schedule. For the other 3 pigeons, no contingency was implemented for treadle pressing. Treadle pressing was established equally in the presence and absence of the observing contingency. The results did not …

Effects of d -amphetamine and morphine on behavior maintained by fixed -interval schedules
… during conventional and clocked FI schedules of food reinforcement. The first experiment compared performance between FI 5-min and continuously clocked FI 5-min components of a multiple schedule in which the rate of the houselight flashing increased in a continuous manner. The second experiment …

Endocannabinoid Modulation of Spatial Memory in Aversively and Appetitively Motivated Barnes Maze Tasks
… but not in operant procedures in which food reinforcement is earned. It is difficult to discern whether the differential effects caused by CB1 receptor disruption on extinction result from the hedonics (i.e., aversive vs. appetitive) or is related to the required responses associated …

Experimental Analysis of Operant Learning with Social Reinforcement in Mice
Social reinforcement/reward (SR) procedures in which operant responses are reinforced by the opportunity to interact in some way with other members of the same species (conspecifics) have been developed to study operant social learning in nonhuman animals, particularly with rats. Interest and …

The Efects of Dose and Time of Administration of Pentylenetetrazol on a Visual Discrimination Task
… after training was completed. Procedure: Using food reinforcement, 36 rats were trained to perform a brightness discrimination in a Y-maze until they reached a criterion of nine out of ten correct responses. They were then injected with either 10.0, 12.5 or 15.0 mg/kg pentylenetetrazol at …

An investigation into the persistence-strengthening effects of differential reinforcement of alternative (DRA) behaviour
… events and ways of introducing differential reinforcement of alternative behaviour (DRA), on the persistence of responding. Of interest was the persistencestrengthening effects of DRA on the target, or problem, behaviour, and whether this could be reduced by training an alternative behaviour …
