This article provides an introduction to the idiographic approach ("N = 1" research) in developmental psychology and an overview of methodological and statistical techniques employed to address the study of within-individual variability in development. Through a popularization of the idiographic approach and associated statistical techniques, but also through technical advances in the apparatus used to produce single-case intensive longitudinal data, the "power" of "N = 1" is becoming increasingly tangible and may challenge, or supplement, established paradigms in nomothetic (group-level) developmental psychology.
本文介绍了发展心理学中的个案研究法（“N = 1”研究），并概述了用于研究个体发展变化的方法和统计技术。通过对个案研究法及相关统计技术的推广，以及用于生成单案例密集纵向数据的仪器设备的技术进步，“N = 1”的“效力”正变得越来越切实可见，可能会挑战或补充实证（群体层面）发展心理学中已确立的范式。
