Contingency and contiguity on the responding by rats exposed to variable interval, variable ratio and variable time schedules of reinforcement

Interação em Psicologia, 2007
In this study, we examined the effects of introducing a delay of reinforcement on the rate and distribution of lever-pressing of eight rats under interval, ratio, and time reinforcement schedules (VI, VR, and VT).

mGluR5 antagonism inhibits cocaine reinforcement and relapse by elevation of extracellular glutamate in the nucleus accumbens via a CB1 receptor mechanism. [PDF]

, 2018
Metabotropic glutamate receptor 5 (mGluR5) antagonism inhibits cocaine self-administration and reinstatement of drug-seeking behavior. However, the cellular and molecular mechanisms underlying this action are poorly understood.

Resurgence of Severe Challenging Behavior and Schedule Thinning with the Terminal Schedule Probe Method

Behavioral Sciences
Multiple schedules promote schedule thinning during treatment for challenging behavior. Some strategies for multiple-schedule-thinning progressions include dense-to-lean (DTL; gradually thinning schedules of reinforcement in small steps), fixed lean (FL;

Reinforcement learning derived chemotherapeutic schedules for robust patient-specific therapy

Scientific Reports, 2021
The in-silico development of a chemotherapeutic dosing schedule for treating cancer relies upon a parameterization of a particular tumour growth model to describe the dynamics of the cancer in response to the dose of the drug.

Ethanol seeking by Long Evans rats is not always a goal-directed behavior. [PDF]

PLoS ONE, 2012
Two parallel and interacting processes are said to underlie animal behavior, whereby learning and performance of a behavior is at first via conscious and deliberate (goal-directed) processes, but after initial acquisition, the behavior can become ...

Maternal Separation Stress Affects Voluntary Ethanol Intake in a Sex Dependent Manner

Frontiers in Physiology, 2021
Maternal separation (MS) stress is a predictive animal model for evaluating the effects of early stress exposure on alcohol use disorders (AUD). The extended amygdala (AMY) is a complex circuit involved in both stress- and ethanol-related responses.

Tracking Photovoltaic Power Output Schedule of the Energy Storage System Based on Reinforcement Learning

Energies, 2023
The inherent randomness, fluctuation, and intermittence of photovoltaic power generation make it difficult to track the scheduling plan. To improve the ability to track the photovoltaic plan to a greater extent, a real-time charge and discharge power ...

Comparing Fixed-amount and Progressive-amount DRO Schedules for Tic Suppression in Youth with Chronic Tic Disorders [PDF]

, 2017
Chronic tic disorders (CTDs) involve motor and/or vocal tics that often cause substantial distress and impairment. Differential reinforcement of other behavior (DRO) schedules of reinforcement produce robust, but incomplete, reductions in tic frequency ...
