The relationship between early life adversity and adult outcomes is traditionally investigated relative to risk and protective factors (e.g., resilience, cognitive appraisal), and poor self-control or decision-making. However, life history theory suggests this relationship may be adaptive-underpinned by mechanisms that use early environmental cues to alter the developmental trajectory toward more short-term strategies. These short-term strategies have some theoretical overlap with the most common process models of decision-making-evidence accumulation models-which model decision urgency as a decision threshold. The current study examined the relationship between decision urgency (through the linear ballistic accumulator) and early life adversity. A mixture of analysis methods, including a joint model analysis designed to explicitly account for uncertainty in estimated decision urgency values, revealed weak-to-strong evidence in favor of a relationship between decision urgency and early life adversity, suggesting a possible effect of life history strategy on even the most basic decisions.
传统上,人们会相对于风险和保护因素(如恢复力、认知评估)以及较差的自我控制或决策能力,来研究早期生活逆境与成年期结果之间的关系。然而,生命史理论表明,这种关系可能是适应性的——其基础机制是利用早期环境线索来改变发展轨迹,使其朝着更短期的策略发展。这些短期策略在理论上与最常见的决策过程模型——证据积累模型有一些重叠,证据积累模型将决策紧迫性建模为一个决策阈值。当前研究考察了决策紧迫性(通过线性弹道累加器)与早期生活逆境之间的关系。多种分析方法,包括旨在明确考虑估计决策紧迫性值的不确定性的联合模型分析,揭示了支持决策紧迫性与早期生活逆境之间关系的证据,证据强度从弱到强,这表明生命史策略甚至可能对最基本的决策产生影响。
