We study individual decision-making behavioral on generic view. Using a formal mathematical model, we investigate the action mechanism of decision behavioral under subjective perception changing of task attributes. Our model builds on work in two kinds classical behavioral decision making theory: "prospect theory (PT)" and "image theory (IT)". We consider subjective attributes preference of decision maker under the whole decision process. Strategies collection and selection mechanism are induced according the description of multi-attributes decision making. A novel behavioral decision-making called "ladder theory (LT)" is proposed . By real four cases comparing, our analysis shows that the LT have better explanation ability then PT and IT under some decision situations. Furthermore, we use our model to shed light on that the LT theory can cover PT and IT ideally. It is the enrichment and development for classic behavioral decision theory and it has positive theoretical value and instructive significance for explaining plenty of decision-making phenomenon,and it improve our understanding of how individual decision-making is performed actually.
