Scaling reward value with demand curves versus preference tests

versus Reward

Paired Preference Tests

In consumer research, the role of the paired preference test appears to be sacrosanct, whether deserved or not. Paired preference simply means putting one product up against another, and instructing the respondent to indicate which one the respondent prefers. The ‘preference’ measure does not show how much one product is liked (or how much more one product is liked versus another). Rather, the ...

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...

Olfactory preference conditioning changes the reward value of reinforced and non-reinforced odors

Olfaction is determinant for the organization of rodent behavior. In a feeding context, rodents must quickly discriminate whether a nutrient can be ingested or whether it represents a potential danger to them. To understand the learning processes that support food choice, aversive olfactory learning and flavor appetitive learning have been extensively studied. In contrast, little is currently k...
