Jon McPhetres, Ph.D.

As a social and biological psychologist, I want to understand how emotions and stress influence our behaviour and cognition, as well as the biological processes that underpin those experiences. 

I like to think of it as psychology from the neck down.

Research Interests

My research looks at physiological changes, like piloerection, to understand emotions.

I measure cardiovascular changes to understand how our body responds to stress.

I look for biomarkers in blood and saliva that can tell us something about the biological processes underpinning our experiences.

I ask questions like:

Why do we get goosebumps?

How do emotions and stress affect our reasoning and decision-making?

What are the physiological processes occurring with different emotions?

How are our biological functions connected to our psychological experience?
