Heightened sensitivity to costs during decision making consistently has been related to substance use. However, no work in this area has manipulated cost information to examine how people evaluate and compare multiple costs. Furthermore, limited work has examined how affective motivations for substance use modulate the evaluation of cost information. We administered a loss-frame variant of the Effort Expenditure for Rewards Task in a diverse community sample (N = 126). Individuals who use substances to avoid negative affect allocated comparable effort across varying likelihoods of loss and computational modeling parameters indicated that they did not systematically consider cost information, which ultimately led these individuals to exert effort when it was disadvantageous to do so. Individuals who use substances to enhance positive affect allocated effort when loss magnitudes were small, suggesting that they effectively compared costs and worked to minimize those costs. Motivations for substance use differentially relate to the comparison of costly information, ultimately influencing effective decision making.

药物滥用的情感动机与在努力决策过程中考虑多种成本有不同的关系。


决策过程中对成本的高度敏感始终与物质使用有关。然而，该领域的工作还没有操纵成本信息来检查人们如何评估和比较多种成本。此外，有限的工作已经研究了物质使用的情感动机如何调节成本信息的评估。我们在不同的社区样本 (N = 126) 中实施了奖励任务的努力支出的损失框架变体。使用物质来避免负面影响的个体在不同的损失可能性和计算模型参数上分配了相当的努力，这表明他们没有系统地考虑成本信息，这最终导致这些个体在不利的情况下付出了努力。当损失幅度较小时，使用物质来增强积极影响的个人会分配努力，这表明他们有效地比较了成本并努力将这些成本降至最低。物质使用的动机与昂贵信息的比较有不同的关系，最终影响有效的决策。 （PsycInfo 数据库记录 (c) 2024 APA，保留所有权利）。
