In today’s saturated digital landscape, capturing and maintaining user engagement is more critical - and more challenging - than ever. One often overlooked but highly potent tool in this effort is sound. Understanding how the brain processes auditory stimuli - particularly music - can inform a more strategic, evidence-based approach to game design, marketing, and user experience.
This article explores the neuropsychology of engagement through the lens of game audio, identifying how our brains respond to sound and how developers and creatives can harness these insights.
Understanding Neuropsychology and Its Relevance to Game Audio
Neuropsychology sits at the intersection of psychology and neuroscience. It combines insights about behavior, emotion, and cognition (our thoughts) with neurological data from the brain and nervous system. The goal in applying neuropsychology to engagement is to adopt a data-informed view of how people respond to sound on both cognitive and emotional levels.
While it’s tempting to think users simply turn off game sound, the reality is quite different.
A 2013 study found that 73% of mobile gamers in the U.S. play with the sound on - 90% in China and Korea, and 58% in the UK. This level of engagement suggests that game audio plays a much more vital role than previously assumed.
Moving Beyond General Analytics
Although traditional user analytics provide valuable insights, they often overlook the emotional dimensions of experience. Today, interest is growing around game audio-specific analytics, which aim to track and measure emotional responses to sound. These methods help capture nuanced reactions that standard metrics might miss, pointing to a richer understanding of user engagement.
From Brain to Behavior: How We Process Sound
When considering how the brain processes music and sound, it’s important to distinguish between two types of processing: top-down and bottom-up.
Top-down processing starts with thoughts, then moves to emotions, and finally triggers a physical response.
Bottom-up processing, where music typically resides, begins in the body. We often feel a physical sensation - goosebumps or chills - before we consciously register an emotion or thought.
This has critical implications for game design and user experience. Even in sedentary environments like mobile gaming, game audio engages the body first, activating emotional and cognitive reactions that drive deeper engagement.
Emotions and Music: A Fast, Deep Connection
Research shows that adults can assign an emotion to a piece of music within seconds. By the age of six, children can do the same (Patel, 2008). Cultural norms play a role - major keys and faster tempos are often associated with positive feelings, while minor keys and slower tempos are linked to negative emotions.
However, recognizing that a piece of music is “sad” doesn’t mean a listener is actually feeling sadness.
The key to engagement lies not in labeling emotions but in triggering them - an area where music excels (Balkwill, L.-L., & Thompson, W. F. 1999).
Three Salient Features That Drive Engagement Through Game Audio
1. Familiarity
The brain loves what it knows. Listeners tend to prefer music they’ve heard before. Even infants demonstrate this preference - research has shown that one-year-olds recognize and respond to music they were exposed to in the womb (Lamont, A, 2001).
Neurologically, this ties back to the brain’s reward system. The neurotransmitter dopamine, which plays a role in attention, memory, and mood, is released when we recognize familiar music, especially during emotionally resonant moments. These experiences are mediated in part by the ventral striatum, a region linked to pleasure and reward (Pereira, Texeira, Figueredo, Xavier, Castro, Brattico, 2011).
Familiarity acts as a bridge between emotional arousal and pleasure, making it a powerful tool in creating game audio experiences that resonate.
2. Repetition
Repetition reinforces familiarity. In music, repetition doesn’t need to be exact - it can manifest as recurring themes, motifs, or structures. Pop music often uses verse-chorus formats that balance predictability with variation.
Repetition enhances engagement in two key ways:
It creates surface pleasure as the listener anticipates and recognizes recurring elements.
It promotes creation pleasure as the brain connects different moments of the musical experience (Garcia, 2005).
