Dopamine responsiveness in Nucleus Accumbens Shell and Core and Prefrontal Cortex during operant behavior for sucrose
Dopamine is implicated in the responsiveness to rewarding properties of natural and pharmacological stimuli. Conditioned stimuli (CS), linked to rewards such as food or drugs of abuse (uncontidioned stimuli, US), are essential to support the motivated behaviour. The role of mesocortical and …

Effects of Candy and Public Recording upon Objective Quiz Scores in a Social Studies Class
… provide evidence that methods in the field of operant behavior are effective in standard classrooms and not just "special" classrooms.

An Analysis of Associative Learning in Drosophila at the Flight Simulator
… consist of a tight conjunction of the animal's behavior (B) with the perceived stimuli. According to the behavior of the animal in response to these stimuli, they are classified as being either biologically neutral (conditioned stimuli, CS) or important (unconditioned stimuli, US or reinforcer). …

The Effects of Cumulative Consumption Feedback On Demand For Money As A Commodity
Behavioral economic theory describes a relation between response requirement and magnitude of reinforcement, and combines these variables into one independent variable (unit price) affecting operant behavior. This study investigated the relative effects of cumulative feedback on consumption for …

Order effects of variability-contingent and variability-independent point delivery: Effects on operant variability and target sequence acquisition.
… that variability is a reinforceable dimension of operant behavior. Additionally, it has been demonstrated that learning is facilitated when variability in responding is high. In this research, variability was observed within an operant composed of any sequence of six left and right key presses. …

Electrical stimulation of reward sites in the ventral tegmental area of the rat increases dopamine transmission in the nucleus accumbens as measured by in vivo microdialysis
… in the nucleus accumbens, rather than intense operant behavior. Further evidence for this hypothesis came from a second set of data in which changes in extracellular DA levels during the measurement of rate/intensity functions for ICSS were positively correlated. 5-HIAA concentrations also …

Control of Pausing in Rich-Lean Transitions by Spatially Localized and Spatially Diffuse Stimuli
… (i.e., rich-lean transitions) can disrupt operant behavior. Previous literature suggests that disruptions in these transitions could occur because individuals engage in other behavior that reduces contact with the schedule-correlated stimuli. My thesis project evaluated this possibility by …

The Acquisition of Mand and Tact Responses
… for investigation of elementary verbal operants is presented.

Operant Assessment of Visual Acuity in the Profoundly Retarded
… The present paper investigated the use of operant conditioning procedures in determining threshold crossings and compared the effectiveness of the staircase and descending series stimulus presentation methods, using a two-response paradigm. Procedure. Three profoundly retarded and two …

Operant Procedures in the Auditory Assessment of "Difficult-To-Test" Individuals
… The present study investigated the use of operant conditioning procedures to determine hearing threshold levels with profoundly retarded individuals. Procedure. Three profoundly retarded individuals were trained to respond on an FR 2 or 3 schedule of reinforcement to puretone presentations …

The Effects of Effleurage as a Nursing Intervention to Promote Prenatal Attachment
The purpose of this study was to examine the effects of effleurage on prenatal attachment. A quasi-experimental research design was used for the study. A group of 49 pregnant women who attended childbirth education classes at a medical center in the Midwest participated in the study. The …

Self-monitoring and self-reinforcement applied to junior college study behavior
… and self-reinforcement in changing study behavior, the adequacy of the experimental procedures utilized in many studies may be questioned. This experiment re-examined the effects these operant conditioning procedures had on the study behavior of junior college evening students by using …

Effects of Ventromedial Hypothalamic Lesions on Food-Reinforced Fixed Ratio Responding
… which these opposite effects on "food-motivated" behavior occur. Rats with ventromedial lesions made with steel electrodes showed a decrease relative to controls in lever pressing on a fixed ratio schedule. This effect was also seen in rats which had extensive pretraining on the fixed ratio task. …

The Effects of a Conflicting Instruction on a Fr 5 Performance
The purpose of this experiment was to evaluate the effects of a conflicting instruction on FR-5 performances by an ABABC design. After all four college students were consistently pressing 1-5-3 followed by sound-clips, the schedule value changed to FR-5 (A). Then they were presented with the …

A Role For Epac1 and Epac2 In Nociceptor Hyperexcitability and Chronic Pain After Spinal Cord Injury
… mouse model and a T10 SCI rat model, we employed behavior assays and electrophysiological techniques to characterize the role of EPAC1 and 2 in SCI-induced pain. We also used three novel methods: the operant mechanical conflict test (MC) behavior test, an electrophysiological measure of ongoing …
