The Anticipation Engine Part 1: Inside the Reward System

Modern streaming has enabled various forms of storytelling, be it in the form of short web series, seasonalized shows, or never-ending soaps. All of the forms listed have a recurring theme: they induce a constant cognitive loop of anticipation, memory and delayed resolution. Across three parts, this series examines the mechanisms that sustain this loop: the neurology of anticipation, the psychology of incompletion, and the social structures that reinforce continuous engagement.

To understand this loop, it is essential to first examine the biological mechanisms behind it. Central to this cycle is dopamine, a neurotransmitter commonly associated with reward and reinforcement. While often simplified as a pleasure-related chemical, its role is more accurately linked to anticipation and predictive processing. In the context of long-form storytelling, dopamine plays a more nuanced role than is typically assumed.

It is not the completion of an episode that produces the strongest dopamine response. According to neuroscientist Wolfram Schultz, dopamine activity is more strongly associated with reward prediction than with reward consumption. Serial narratives exploit this mechanism by creating multiple narrative threads and delaying emotional closure, ensuring that viewers remain in a sustained state of anticipation for forthcoming resolutions.

Creators also leverage another related mechanism. When closure is provided, it is often structurally incomplete rather than fully resolved. In later work, Schultz describes this through the concept of reward prediction error, where dopamine activity is modulated when outcomes deviate from expectation. Such deviations compel the cognitive system to continuously update its predictive model, thereby sustaining attentional engagement.

This next point shifts toward cognitive psychology, but fits within the same framework. As demonstrated in Green and Brock’s 2000 study on narrative transportation, individuals can become mentally immersed in fictional narratives to the extent that attentional and emotional systems associated with real-world experience are activated. Narrative engagement recruits cognitive processes involved in social evaluation, leading the brain to process fictional events with functional relevance. This is further reinforced through parasocial interaction, as described by Horton and Wohl, where repeated exposure to characters produces one-sided emotional bonds, allowing fictional figures to acquire lasting emotional salience within the viewer’s cognitive framework.

While this section outlines the biological and cognitive foundations of engagement, the next part will focus on the psychological mechanisms of incompletion and how narrative structures sustain attention over time.
