Final answer:
Being able to add a new piece to an existing frame is known as extension. This is part of the frame alignment process in social movements, where extension involves broadening the movement's appeal to include additional interests.
Step-by-step explanation:
Being able to add a new piece to an existing frame is known as extension. This concept is often related to the frame alignment process in social movements, where extension refers to the enlargement of the frame to encompass interests or points of view that are not previously articulated within the frame. An example of this would be when, after successfully achieving women's suffrage, the League of Women Voters had to undergo a process of completely changing their goals to stay relevant—which is known as frame transformation. Extension is distinct from transformation, as it involves expanding on existing goals, rather than a complete change.
Frame alignment has four aspects: bridging, amplification, extension, and transformation. In the context of social movements, these are strategies utilized to connect organizations and individuals to a greater cause. An example of bridging would be diverse organizations that share a similar goal teaming up to form a more powerful collective force. Whereas extension would involve broadening a movement's scope to include additional, related issues or objectives to recruit a wider audience and sustain its vitality.
