What are psychological constructs? On the nature and statistical modeling of emotions, intelligence, personality traits and mental disorders.

Many scholars have raised two related questions: what are psychological constructs such as cognitions, emotions, attitudes, personality characteristics, and intelligence? And how are they best modeled statistically? This paper provides (1) an overview of common theories and statistical models, (2) connects these two domains, and (3) discusses how the recently proposed framework pragmatic nihilism (Peters & Crutzen, 2017) fits in.

众多学者提出了两个相关的问题：心理结构，诸如认知、情感、态度、人格特性和智力等，究竟为何物？以及如何最佳地对其进行统计学建模？本文旨在（1）概述常见理论与统计模型，（2）将这两个领域相连接，并（3）探讨近期提出的框架——实用虚无主义（Peters & Crutzen, 2017）如何与之契合。
