One goal of social science in general, and of psychology in particular, is to understand and predict human behavior. Psychologists have traditionally used self-report measures and performance on laboratory tasks to achieve this end. However, these measures are limited in their ability to predict behavior in certain contexts. We argue that current neuroscientific knowledge has reached a point where it can complement other existing psychological measures in predicting behavior and other important outcomes. This approach integrates traditional neuroimaging methods with measures of behavioral outcomes that extend beyond the immediate experimental session. Previously, most neuroimaging experiments focused on understanding basic psychological processes that could be directly observed in the laboratory. However, recent experiments have demonstrated that brain measures can predict outcomes (e.g., purchasing decisions, clinical outcomes) over longer timescales in ways that go beyond what was previously possible with self-report data alone. This approach can be used to reveal the connections between neural activity in laboratory contexts and longer-term, ecologically valid outcomes. We describe this approach and discuss its potential theoretical implications. We also review recent examples of studies that have used this approach, discuss methodological considerations, and provide specific guidelines for using it in future research.
一般而言,社会科学的一个目标,尤其是心理学的目标,是理解和预测人类行为。传统上,心理学家使用自我报告测量法以及实验室任务中的表现来达成这一目的。然而,这些测量方法在预测特定情境下的行为方面能力有限。我们认为,当前的神经科学知识已经发展到这样一个阶段,即在预测行为和其他重要结果方面,它可以补充其他现有的心理学测量方法。这种方法将传统的神经成像方法与行为结果测量相结合,这些行为结果测量超出了即时实验环节的范围。以前,大多数神经成像实验专注于理解那些可以在实验室中直接观察到得基本心理过程。然而,最近的实验表明,大脑测量能够在更长的时间尺度上预测结果(例如购买决策、临床结果),其方式超越了仅靠自我报告数据之前所能做到的。这种方法可用于揭示实验室情境中的神经活动与更长期、生态效度高的结果之间的联系。我们描述这种方法并讨论其潜在的理论意义。我们还回顾了最近使用这种方法的研究实例,讨论方法学上的考虑因素,并为在未来研究中使用该方法提供具体指导方针。
