Reinstatement of postresponse stimuli prior to reward in delayed-reward discrimination learning by pigeons

Discrimination Learning Without Reward I

THE long standing question surrounding the necessary and sufficient conditions for learning are as real today as when originally posed in the first half of the century [4, 6, 9]. The past years of formalizing data from animal learning experiments has yielded more adaptation to the problem than understanding. Curiously, the simple theoretical notions derived from this work (SR theory, contiguity...

Theory meets pigeons: the influence of reward-magnitude on discrimination-learning.

Modern theoretical accounts on reward-based learning are commonly based on reinforcement learning algorithms. Most noted in this context is the temporal-difference (TD) algorithm in which the difference between predicted and obtained reward, the prediction-error, serves as a learning signal. Consequently, larger rewards cause bigger prediction-errors and lead to faster learning than smaller rew...

Asymptotic Behavior of Multivariate Reward Processes with Nonlinear Reward Functions

COVARIANCE MATRIX OF MULTIVARIATE REWARD PROCESSES WITH NONLINEAR REWARD FUNCTIONS

Multivariate reward processes with reward functions of constant rates, defined on a semi-Markov process, first were studied by Masuda and Sumita, 1991. Reward processes with nonlinear reward functions were introduced in Soltani, 1996. In this work we study a multivariate process , , where are reward processes with nonlinear reward functions respectively. The Laplace transform of the covar...
