a b s t r a c tintroduction: although decision-making processes have become a principal target of study among addiction researchers, few researches are published according to effects of different treatment methods on the cognitive processes underlying decision making up to now. utilizing cognitive modeling method, in this paper we examine the effects of methadone maintenance treatment (mmt) on ...

We establish a sharp large deviation principle for renewal-reward processes, supposing that each renewal involves broad-sense reward taking values in real separable Banach space. In fact, we demonstrate weak without assuming any exponential moment condition on the law of waiting times and rewards by resorting to version Cram\'er's theorem. also exhibit sufficient conditions tightness which lead...

It is thought that reward-induced motivation influences perceptual, attentional, and cognitive control processes to facilitate behavioral performance. In this study, we investigated the effect of reward-induced motivation on exogenous attention orienting and inhibition of return (IOR). Attention was captured by peripheral onset cues that were nonpredictive for the target location. Participants ...

Let {(Xi; Yi): i= : : : ;−1; 0; 1; : : :} be a doubly in nite renewal-reward process, where {Xi: i= : : :− 1; 0; 1; : : :} is an i.i.d. sequence of renewal cycle lengths and Yi= g(Xi−q; Xi−q+1; : : : ; Xi) is the lump reward earned at the end of the ith renewal cycle, with some function g :R q+1 → R . Starting with the rst renewal cycle (of duration X1) at the time origin, let C(t) denote the e...
