This paper examines the family interaction processes of modem Taiwanese people and their effect on individual psychological and behavioral development. Family-related issues investigated with respect to Taiwanese people in the past 4 years can be categorized into 4 subprojects: (1) the influence of beliefs in destiny and yuan, (2) the influence of marital power and affection and their relationship with co-parenting patterns and couples’ interactions, (3) an empirical test of the Dual Filial Piety model, and (4) the influence of the parent-child relationship on the development of children’s autonomy and daughters’ father-hunger complex. This article discusses the common theoretical background of the 4 subprojects, explains the purpose and findings of each subproject, and provides suggestions for further study of family interaction in modem Taiwanese society.
