Abstract sentences elicit more uncertainty and curiosity than concrete sentences

Are abstract sentences associated with specific constructs in dialogue, i.e., higher uncertainty, more curiosity and willingness to continue the conversation, and more causal questions? In three preregistered experiments we address these questions asking participants to evaluate the plausibility of linguistic exchanges referred to concrete and abstract concepts. Results support theories proposing that abstract concepts involve more inner monitoring and social dynamics compared to concrete concepts, and suggest that reaching alignment in dialogue is more effortful with abstract than with concrete concepts.
