Categorization processes in emotion expression recognition: The roles of language and essentialism.

We examined categorical processing biases in the perception and recognition of facial expressions of emotion across two studies. In both studies, participants first learned to discriminate between two ambiguous facial expressions of emotion selected from the middle of a continuous array of blended expressions (i.e.

Spontaneous Anthropocentric Language Use in University Students' Explanations of Biological Concepts Varies by Topic and Predicts Misconception Agreement.

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.

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.
