Think about what keeps you coming back to your favorite store, your favorite person or even your favorite website. It’s not just a mindless buy-go, hug-go or click-go relationship. It is a complicated, emotional connection. It is what makes relationships with people and brands intoxicating. User engagement must have an equally complex emotional connection. It must affect the user in mind, body and spirit. Anything less is a 1990s brochure website.

You can create strong storytelling strategies based on user personalities and segmentation. However, it seems almost impossible to measure those efforts, let alone know how to optimize them, without access to a neuroscience laboratory. In fact, emotional engagement can be optimized, and quite effectively, using something already at your disposal: performance metrics.

Emotional-Behavioral Response Relationship

Let’s start with the basics: an emotion is a psychophysiological response in your body to a stimulus. It’s an internal process that in turn triggers an external behavioral response. Behavioral responses help you decipher the emotional responses of others. Things like facial expressions and body language give you clues to whether the chef wielding the knife is angry and going to attack you or happy and going to make you dinner.

For example:

But you don’t have to be face to face in order to read a person’s behavioral clues. In digital environments, users’ behavioral interactions with the platform can give you insight into their emotional states. Instead of reading facial cues to analyze how your UX efforts affect users, you can measure their responses via metric data. Metric data is a user’s behavioral response quantified. With a little reverse engineering, you can identify strong emotional triggers, optimize weak elements and create stronger user experience strategies, using psychology as your secret weapon.

By The Numbers: Behavioral Response

Behavioral psychologists have classified emotions in numerous different theories. A large majority of these theories agree that emotions manifest in various intensities and can even combine with others to build new emotional states. One example of such a theory is Robert Plutchik’s emotion wheel.
