Past and future preference reversals are predicted by delay discounting in smokers and non-smokers.

Abstract：

:Delay discounting, the devaluation of delayed reinforcers, is one defining behavioral economic characteristic of cigarette smokers. Attempts at abstinence by smokers that result in relapse are conceptualized in this framework as preference reversals. Despite preference reversals being predicted by delay discounting models, little research has investigated the association between discount rate and preference reversals. The present study extended this research by examining the relation between discounting and preference reversals. Because previous research indicates that cigarette smokers discount at higher rates than controls and that past and future discounting are symmetrical, the present study assessed the relation between these two processes when hypothetical money was distanced in the past and future, respectively. These assessments of delay discounting and preference reversals were adapted from Yi, Matusiewicz, and Tyson (2016) and examined in 68 smokers and 68 nonsmokers using the crowdsourcing program Amazon Mechanical Turk. Smokers discounted both past and future hypothetical money more steeply than demographically matched controls. Smokers switched preference from the smaller-sooner (SS) to the larger-later (LL) outcome more slowly than nonsmokers, consistent with smokers' steeper delay discounting. For each group, significant positive correlations between past and future discount rates and past and future preference reversals was obtained. The overall pattern of results illustrate symmetry between past and future discounting and preference reversals, respectively and that discount rate is positively associated with the timing of preference reversals. Importantly, the results confirm that cigarette smokers discount more and reverse preference from a SS to a LL reward later than controls.
