Reward and reward omission: Time-dependent aftereffects in rats and fish

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...

Dorsomedial striatum lesions affect adjustment to reward uncertainty, but not to reward devaluation or omission.

The dorsomedial striatum (DMS) has been implicated in the acquisition of reward representations, a proposal leading to the hypothesis that it should play a role in situations involving reward loss. We report the results of an experiment in which the effects of DMS excitotoxic lesions were tested in consummatory successive negative contrast (reward devaluation), autoshaping training with partial...

An examination of "nonleadership": from laissez-faire leadership to leader reward omission and punishment omission.

Laissez-faire leadership has received much less attention than have the 3 transactional leadership dimensions of the Multifactor Leadership Questionnaire (MLQ). However, laissez-faire leadership has shown strong negative relationships with various leadership criteria, and the absence of leadership (laissez-faire leadership) may be just as important as is the presence of other types of leadershi...

Thalamic Regulation of Sucrose Seeking during Unexpected Reward Omission.

The paraventricular nucleus of the thalamus (PVT) is thought to regulate behavioral responses under emotionally arousing conditions. Reward-associated cues activate PVT neurons; however, the specific PVT efferents regulating reward seeking remain elusive. Using a cued sucrose-seeking task, we manipulated PVT activity under two emotionally distinct conditions: (1) when reward was available durin...
