采用GARP的一个变体，我们通过比较年轻人（YA）和老年人（OA）在“简单”，两个好和“复杂”三个好条件下的选择来研究衰老的一致性。我们发现，OA表现比YA在复杂的条件下，但类似于YA在简单的条件下，无论是在数量和严重程度的GARP违规。工作记忆和智商分数与一致性水平显着相关，但仅在复杂的处理。我们的研究结果表明，与年龄相关的负责工作记忆和液体智力的神经功能的退化是一致决策的障碍。(C)2018爱思唯尔B.V.保留所有权利。
Employing a variant of GARP, we study consistency in aging by comparing the choices of younger adults (YA) and older adults (OA) in a "simple", two-good and a "complex" three-good condition. We find that OA perform worse than YA in the complex condition but similar to YA in the simple condition, both in terms of the number and severity of GARP violations. Working memory and IQ scores correlate significantly with consistency levels, but only in the complex treatment. Our findings suggest that the age-related deterioration of neural faculties responsible for working memory and fluid intelligence is an obstacle for consistent decision-making. (C) 2018 Elsevier B.V.
