Hi, I'm Emma Herms

Sensory information, via our eyes, ears, and other organs, forms the foundation of our lived experience. Yet we find ourselves perceiving the world differently from our family, friends, and the person sitting next to us at our favorite sports event, who calls the ball out when it clearly hit the line! So how accurate is our perception, really? This isn’t just an intellectual question about the physiological and psychological processes happening throughout our body; it has real world consequences.

Our brain is constantly keeping track of the experience of our body in the environment, enabling us to determine where we are, how we feel, and respond appropriately. How does this work? Let’s find out! Researchers parse the experience of our body into three domains: exteroception, proprioception, and interoception. Are you familiar with these terms? What type of information do each of these domains contribute to the experience of the body in the image to the right?

Researchers and mental health professionals use a common definition to describe delusions: a fixed, false belief held despite contradictory evidence. Not only does this definition fail to distinguish delusions from other widespread beliefs, such as religious or ideological beliefs, but it also attempts to simplify delusions to an individual characteristic of irrationality (i.e., the person has failed to distinguish what is true and false. This conceptualization of delusions has been criticized, and new theories have emerged, which focus on the inherently social nature of acquiring beliefs. This framework might better explain why delusions exist in the general population and identify some ways in which false beliefs can form...

What are common emotions experienced in your culture? In the United States, happiness, anger, sadness, and fear are considered common emotions. The traditional theory of emotion assumes emotions are universally recognized by all humans. This theory dominates pop culture, with movies like Pixar’s Inside Out, which features characters personifying five emotions that coordinate our every action, and items like Amazon’s Halo Watch, which claims to detect emotions based on tone of voice. Yet, it is not possible to determine what emotion someone is experiencing based only on their face or tone of voice. Instead, our brain makes a prediction that is influenced by past experience, the current context, and interoceptive signals from our body (e.g., heart and breathing rate, hunger cues) from a culture-specific perspective...
