Measures of cognitive ability and choice inconsistency
研究了瑞文推理测验和认知反射测试两种认知能力测量方法的相关性，发现两者正相关且都能预测儿童和成人在激励任务中的行为不一致性。
Cognitive skills affect individual choices. Researchers commonly use Raven's Progressive Matrices (RPM) tests and the Cognitive Reflection Test (CRT) to assess the relationship between cognitive abilities and economic decision making. In this paper, we study the relationship between these measures, and investigate the extent to which they are correlated and whether they are best described as substitutes or complements. Combining a sample of 686 children and a sample of 2,332 adults, we compare individual performances in the RPM test and CRT test. First, we report a significant positive correlation between the two measures of 0.3. Second, we document that performance in both the RPM test and CRT are significant predictors of behavioral inconsistency observed in incentivized time and risk preference elicitation tasks for children and risk preference elicitation task for adults.
