Which architectural concept relates forms with tangible objects or processes?

The correct answer is the thematic concept. This architectural concept focuses on creating relationships between design forms and the tangible objects or processes they represent. Thematic concepts often draw upon narratives or overarching themes that guide the design process, ensuring that the architecture resonates with the intended symbolic meanings or functions associated with those forms.

For instance, a thematic approach might lead to designs that reflect cultural narratives, historical contexts, or environmental conditions, creating a more profound connection between the built environment and human experience. It allows architects to invoke specific themes that can inform materiality, spatial organization, and aesthetics, resulting in designs that not only serve a functional purpose but also tell a story or evoke particular feelings tied to the objects or processes they embody.

In contrast, other concepts such as information theory, the semiotic approach, and the empirical approach, while relevant in the broader discourse of architecture, do not specifically center on the relationship between architectural forms and tangible objects or processes in the same direct manner as the thematic concept does. Information theory deals more with communication aspects, the semiotic approach focuses on signs and symbolism in architecture, and the empirical approach emphasizes observable evidence and practicality rather than thematic narratives.
