Thinking Climate Change through the Lens of Abstractness: a Multi-Task and Multi-Setting Investigation into Generational Differences in the Conceptualization of Ecology

To face ecological disasters, one of the major emergencies of modern times, fostering pro-environmental behaviors appears crucial. While research explored various behavioral drivers, few studies addressed the conceptual representation of ecological events at different ages. Our preregistered study fills this gap, examining how different generations conceptualize ecology, considering evidence suggesting a link between climate change abstractness and willingness to act pro-environmentally.Older (>65 yo) and younger (18-35 yo) individuals performed multiple tasks targeting conceptual processing (categorization), semantic organization (rating), and conceptual representation (feature generation) of ecological (e.g., deforestation) compared to concrete (e.g., spoon) and abstract (e.g., affirmation) concepts. In the categorization task, participants responded to critical ecological, concrete, and abstract words but refrained from responding to animal words. The rating task involved evaluating critical words on semantic aspects (e.g., Abstractness, Familiarity), and the feature generation task listing properties true for each concept. Innovatively, participants were tested in three possible settings (indoor, natural outdoor, urbanized outdoor) to test whether exposure to nature impacts categorization.Results showed that independent from the setting, ecological concepts were similar to abstract concepts, especially in semantic organization and conceptual representation, or more abstractly characterized than them, especially in conceptual processing. Age differences were minimal, but older adults characterized ecological concepts more concretely than younger adults. Theoretically, the multifarious characterization of ecological phenomena points to the necessity of overcoming the classical concrete-abstract dichotomy. From a societal point of view, the abstractness of ecological concepts might inform policies to promote pro-environmental behaviors.
