Adults' learning of complex explanations violates their intuitions about optimal explanatory order.

Should you first teach about the purpose of a microwave or about how it heats food? Adults strongly prefer explanations to present function before mechanism and information about a whole to precede information about its component parts. Here we replicate those preferences (Study 1). Using the same stimuli, we then ask whether those pedagogical preferences reflect ease of learning of labels, function, or mechanism.

An Atomic-Scale Vector Network Analyzer.

Electronic devices have been ever-shrinking toward atomic dimensions and have reached operation frequencies in the GHz range, thereby outperforming most conventional test equipment, such as vector network analyzers (VNA). Here the capabilities of a VNA on the atomic scale in a scanning tunneling microscope are implemented. Nonlinearities present in the voltage-current characteristic of atoms and nanostructures for phase-resolved microwave spectroscopy with unprecedented spatial resolution at GHz frequencies are exploited.

Conceptualizing Human-Nature Relationships: Implications of Human Exceptionalist Thinking for Sustainability and Conservation.

The ways in which people conceptualize the human-nature relationship have significant implications for proenvironmental values and attitudes, sustainable behavior, and environmental policy measures. Human exceptionalism (HE) is one such conceptual framework, involving the belief that humans and human societies exist independently of the ecosystems in which they are embedded, promoting a sharp ontological boundary between humans and the rest of the natural world. In this paper, we introduce HE in more depth, exploring the impact of HE on perceptions of the human-nature relationship, the role of culture in HE, and speculating on the origins of HE.

Development of Conceptual Flexibility in Intuitive Biology: Effects of Environment and Experience.

Living things can be classified in many ways, such as taxonomic similarity (lions and lynx), or shared ecological habitat (ducks and turtles). The present studies used card-sorting and triad tasks to explore developmental and experiential changes in -the ability to switch between taxonomic and ecological construals of living things-as well as two processes underlying conceptual flexibility: (i.e.

Cognitive Construal-Consistent Instructor Language in the Undergraduate Biology Classroom.

Researchers have identified patterns of intuitive thinking that are commonly used to understand and reason about the biological world. These (anthropic, teleological, and essentialist thinking), while useful in everyday life, have also been associated with misconceptions about biological science. Although construal-based thinking is pervasive among students, we know little about the prevalence of construal-consistent language in the university science classroom.
