Adding a reward increases the reinforcing value of fruit [PDF]

open access: yes, 2017
Adolescents' snack choices could be altered by increasing the reinforcing value (RV) of healthy snacks compared with unhealthy snacks. This study assessed whether the RV of fruit increased by linking it to a reward and if this increased RV was comparable

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

open access: yesAlgorithms, 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 ...

Selective disruption of stimulus-reward learning in glutamate receptor gria 1 knockout mice. [PDF]

open access: yes, 2003
Glutamatergic neurotransmission via AMPA receptors has been an important focus of studies investigating neuronal plasticity. AMPA receptor glutamate receptor 1 (GluR1) subunits play a critical role in long-term potentiation (LTP).

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

open access: yesPLoS 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.

Hypocretin-1 receptors regulate the reinforcing and reward-enhancing effects of cocaine: pharmacological and behavioral genetics evidence. [PDF]

open access: yes, 2012
Considerable evidence suggests that transmission at hypocretin-1 (orexin-1) receptors (Hcrt-R1) plays an important role in the reinstatement of extinguished cocaine-seeking behaviors in rodents.

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

open access: yesBrain 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.

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

open access: yesУчёные 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 ...

Adolescent methylphenidate treatment differentially alters adult impulsivity and hyperactivity in the Spontaneously Hypertensive Rat model of ADHD [PDF]

open access: yes, 2016
Impulsivity and hyperactivity are two facets of attention deficit/hyperactivity disorder (ADHD). Impulsivity is expressed as reduced response inhibition capacity, an executive control mechanism that prevents premature execution of an intermittently ...

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

open access: yesFrontiers 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.
