Final answer:
Various theorists and techniques can be applied to position and engage the audience through representational and narrative structural techniques.
Step-by-step explanation:
Regarding the representational and narrative structural techniques used to position and engage/hook the audience, there are several theorists that can be applied. One theorist is Erving Goffman, who developed the technique of dramaturgical analysis. Goffman used theater as an analogy for social interaction and recognized that people's interactions showed patterns of cultural 'scripts.'
In addition to Goffman, there are also elements of narrative storytelling techniques, such as descriptive and narrative techniques to help readers imagine the subject, and spatial structure used in profiles of buildings and artworks. These techniques help to engage the audience and create a compelling narrative.
Furthermore, understanding visual rhetoric and how it can be analyzed and written about persuasively is also relevant to positioning and engaging the audience. Visual rhetoric includes conventions like arrangement, color and symbol, composition, and point of view.
