Information on climate change and Attentional Dynamics in Consumers’ Seafood Choices: An Approach from RUM-DFT 1: Universidad del Desarrollo, Chile; 2: Universidad de Concepción Information-based interventions are commonly proposed to promote sustainable consumption, yet their effectiveness may depend on how individuals dynamically process attributes during decision making. This paper examines how climate-change information—specifically ocean acidification (OA)—affects seafood preferences through attentional dynamics rather than static shifts in utility. We use a Random Utility Maximization–Decision Field Theory (RUM-DFT) framework, which integrates discrete choice modeling with psychological process models to explicitly capture sequential attention allocation and time-dependent preference formation. The empirical application relies on a stated-preference choice experiment on bivalve seafood products, where respondents were randomly assigned to an OA information treatment or a control group, generating 7,524 choice observations from 627 individuals. We estimate RUM-DFT models under alternative deliberation-time bounds to identify how information affects both attention shares and implied preference parameters over the course of the decision process. Results show that OA information produces a transient increase in attention toward environmentally relevant credence attributes during early deliberation, but these effects weaken—and can reverse—when deliberation time extends, with attention progressively concentrating on perceptually salient attributes such as visual appearance. These patterns support an attribute latency mechanism in which perceptual and abstract information enter evidence accumulation at different stages. The findings imply that climate information does not induce stable preference changes; instead, it modifies choice outcomes through temporally evolving attention processes that static random utility models cannot recover. Policy implications emphasize that effective sustainability interventions should go beyond information provision and focus on attention management via salience-enhancing designs, simplified metrics, and decision architectures that prevent cognitive overload. | |
