Aquanauts—people who live and work underwater for extended periods—have anecdotally reported cognitive shifts in how they perceive the ocean environment and their role in it. This experience bears resemblance to the cognitive shift astronauts have experienced when first seeing our planet from space, dubbed “The Overview Effect.” This shift involves an intense feeling of awe that increases astronauts’ sense of connection to humanity and the entire planet. In this study, we used semi-structured interviews with aquanauts to document their experiences living underwater. Results show that aquanauts do indeed experience shifts in cognitive, affective, behavioral, perspectival, and relational areas that strengthen feelings of connectedness and commitment to the marine environment. However, the effects of the experience varied between aquanauts, indicating a potential “Underview Effect” that may occur on a spectrum of intensity with a number of core features. 

Mental models—internal, dynamic, incomplete representations of the external world that people use to guide cognitive processes such as reasoning, decision making, and language comprehension—have practical implications for predicting attitudes and behaviors across various domains. This study examines how mental models of the human–nature relationship predict pro-environmental behavioral intentions directly and indirectly as mediated through anthropocentric and biocentric environmental attitudes. To address these aims, participants were asked about mental model components of the human–nature relationship (human exceptionalism, beliefs about human impact on nature, and beliefs about nature’s impact on humans), pro-environmental attitudes (biocentric and anthropocentric), and their pro-environmental behavioral intentions (protection and investment). We found that protection intentions were (1) directly predicted by human exceptionalism beliefs (negatively) and perceived human impact on nature (positively) and (2) indirectly predicted by mental model components via biocentric attitudes. Investment intentions were directly predicted by nature’s perceived impact on humans, and were similarly indirectly predicted by mental model components via biocentric attitudes. The results suggest that mental models of the human–nature relationship provide a cognitive foundation for environmental behavioral intentions both directly and through their association with environmental attitudes. These findings have implications for pro-environmental interventions that deal with conceptual and attitudinal change. 

Previous research has shown that students employ intuitive thinking when understanding scientific concepts. Three types of intuitive thinking—essentialist, teleological, and anthropic thinking—are used in biology learning and can lead to misconceptions. However, it is unknown how commonly these types of intuitive thinking, or cognitive construals, are used spontaneously in students’ explanations across biological concepts and whether this usage is related to endorsement of construal-consistent misconceptions. In this study, we examined how frequently undergraduate students across two U.S. universities ( N = 807) used construal-consistent language (CCL) to explain in response to open-ended questions related to five core biology concepts (e.g., evolution), how CCL use differed by concept, and how this usage was related to misconceptions agreement. We found that the majority of students used some kind of CCL in the responses to these open-ended questions and that CCL use varied by target concept. We also found that students who used CCL in their response agreed more strongly with misconception statements, a relationship driven by anthropocentric language use, or language that focused on humans. These findings suggest that American university students use intuitive thinking when reasoning about biological concepts with implications for their understanding.
