This document discusses three types of conceptual frameworks: overlapping domains, sequential, and ecological. The overlapping domains framework represents intersections between different aspects of a concept, emphasizing complexity and interconnections. The sequential framework organizes concepts or variables in a linear sequence to illustrate temporal or causal relationships. The ecological framework views phenomena within broader environmental contexts and highlights interactions between individuals and their surroundings at various levels. It then provides an example of using attachment theory as a theoretical framework to examine how the expression of romantic love differs across cultures.
