Event details
Abstract
This talk examines how vertical farming comes to be constituted as an object of social representations through metaphorical processes of objectivation. Drawing on social representations theory, it introduces the Portrait Chinois as a projective technique for eliciting the metaphors through which meaning is negotiated around emerging agri-food technologies. Participants from a range of stakeholder groups - including procurers and retailers, vertical farmers, conventional farmers, policymakers, scholars, and NGOs - were invited to respond to a series of ‘if vertical farming were…’ prompts. The analysis shows how metaphors render an unfamiliar and complex technology socially intelligible, while revealing underlying values, tensions, and expectations. Methodologically, the talk highlights the value of the Portrait Chinois for accessing the symbolic and affective dimensions of social representations across diverse social worlds.

Biography
I earned my PhD in Food, Sensory, and Perception Sciences at the Centre des Sciences du Goût, Université de Bourgogne. My work as a Sensory Perception Scientist is grounded in both cognitive and social psychology, examining how sensory experience is shaped not only by stimuli, but by the social representations, beliefs, and contextual frameworks individuals draw upon when interpreting those stimuli. Through studies using foods, beverages, and flowers, I explore how meaning, memory, and cultural knowledge influence the construction of perceptual reality.
