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).

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.

Demand Response Strategy Based on Reinforcement Learning and Fuzzy Reasoning for Home Energy Management [PDF]

, 2020
As energy demand continues to increase, demand response (DR) programs in the electricity distribution grid are gaining momentum and their adoption is set to grow gradually over the years ahead. Demand response schemes seek to incentivise consumers to use

Sex and Feeding Status Differently Affect Natural Reward Seeking Behavior in Olfactory Bulbectomized Rats

Frontiers in Behavioral Neuroscience, 2018
Substance abuse and depression are common psychiatric disorders with a high rate of comorbidity. Both conditions affect differently men and women and preclinical research has showed many sex differences in drug addiction and depression.
