In this paper we present a new computational framework of affective-cognitive learning and decision making for affective agents, inspired by human learning and recent neuroscience and psychology. In the proposed framework ‘internal reward from cognition and emotion’ and ‘external reward from the external world’ serve as motivation in learning and decision making. We construct this model, integr...

Choosing one reward above another is important for achieving adaptive life goals. Yet hijacked into excessive intensity in disorders such as addiction, single-minded pursuit becomes maladaptive. Here, we report that optogenetic channelrhodopsin stimulation of neurons in central nucleus of amygdala (CeA), paired with earning a particular sucrose reward in rats, amplified and narrowed incentive m...

Introduction: selecting a specialty is one of the most difficult decision of medical practitioners, and this selection depends on personal factors, such as motives and dimensions of personality traits. Therefore, this study investigates relation between of dimensions of Personality traits on selecting the specialty for Medical Students of Mashhad University of Medical SciencesMethods: This cros...

This chapter presents a generic internal reward system that drives an agent to increase the complexity of its behavior. This reward system does not reinforce a predefined task. Its purpose is to drive the agent to progress in learning given its embodiment and the environment in which it is placed. The dynamics created by such a system are studied first in a simple environment and then in the co...

this review gives an overview of our recent findings and developments in research on brain mechanisms of morphine reward from studies using the place preference conditioning paradigm. intracranial place conditioning methodology has become a valuable and firmly established and very widely used tool in behavioural pharmacology and drug reward mechanisms. several studies have established that morp...

The paper explores a very simple agent design method called Q-decomposition, wherein a complex agent is built from simpler subagents. Each subagent has its own reward function and runs its own reinforcement learning process. It supplies to a central arbitrator the Q-values (according to its own reward function) for each possible action. The arbitrator selects an action maximizing the sum of Q-v...

In the past decade, there has been an increasing interest in the effects of rewards on visual perception. Exogenous rewards have been shown to increase visual sensitivity and to affect attentional selection. Human beings, however, also feel rewarded by the correct execution of a task. It has been proposed that this form of endogenous reward triggers reinforcement signals in the brain, making th...

It was proposed that people attribute an individual’s behavior more to internal factors when that individual’s actions are influenced by reward than when those actions are influenced by punishment. Previous research has failed to control for the power of reward versus punishment which, in effect, creates a confounding of behavioral base rates (consensus) with the reward-punishment manipulation....

this study was aimed at investigating the impact of organizational factors, leadership style, reward system and job design on psychological empowerment and its dimensions. this study was also aimed at measuring the level of employees' psychological empowerment. applied research method was survey-correlation using questionnaire as the measurement tool. statistical population included all em...
