Modeling the violation of reward maximization and invariance in reinforcement schedules.

PLoS Computational Biology, 2008
It is often assumed that animals and people adjust their behavior to maximize reward acquisition. In visually cued reinforcement schedules, monkeys make errors in trials that are not immediately rewarded, despite having to repeat error trials.

Balancing Project Schedule, Cost, and Value under Uncertainty: A Reinforcement Learning Approach

Algorithms, 2023
Industrial projects are plagued by uncertainties, often resulting in both time and cost overruns. This research introduces an innovative approach, employing Reinforcement Learning (RL), to address three distinct project management challenges within a ...

Neuropsychology of reinforcement processes in the rat [PDF]

, 2011
This thesis investigated the role played by regions of the prefrontal cortex and ventral striatum in the control of rats’ behaviour by Pavlovian conditioned stimuli, and in their capacity to choose delayed reinforcement.

The Influence of Reinforcement on Aspects of Killer Whale Innovation under Stimulus Control

International Journal of Comparative Psychology
Creativity research suggests that creative output can be influenced by extrinsic rewards. Through reinforcement, individual killer whales were trained to produce varied behaviors to a particular cue.

Ethanol Reinforcement Elicits Novel Response Inhibition Behavior in a Rat Model of Ethanol Dependence

Brain Sciences, 2018
Lower impulse control is a known risk factor for drug abuse vulnerability. Chronic experience with illicit drugs is suggested to enhance impulsivity and thereby perpetuate addiction.

Hungry pigeons prefer sooner rare food over later likely food or faster information

Frontiers in Psychology
IntroductionMaking decisions and investing effort to obtain rewards may depend on various factors, such as the delay to reward, the probability of its occurrence, and the information that can be collected about it.

Refinement of biologically inspired models of reinforcement learning [PDF]

, 2010
Reinforcement learning occurs when organisms adapt the propensities of given behaviours on the basis of associations with reward and punishment. Currently, reinforcement learning models have been validated in minimalist environments in which only 1-2 ...

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;

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).

Effects of neonatal NMDA-subtype glutamate receptor blockade on behavior of adult male rats

Учёные записки Санкт-Петербургского государственного медицинского университета им. Акад. И.П. Павлова, 2022
Introduction. Cognitive impairments are important components of the clinical picture of many neuropsychiatric disorders, and are in dire need of evidence-based pharmacotherapeutic approaches.The objective was to test a model of delayed cognitive ...
