Media Engagement and Behavioral Psychology

Vocabulary flashcards detailing principles of media engagement, operant conditioning schedules, psychological biases, and reward neurobiology.

Graphical Abstract

A visual summary of a research paper condensed into a single picture to communicate findings quickly.

Infinite Scroll

A continuous feed design feature with no clear stopping point, utilized by platforms like Facebook, Twitter, Pinterest, and TikTok to prolong user engagement.

Streaks

A behavioral engagement mechanic requiring users to repeat the same action at set intervals, making the preservation of the streak an important personal goal.

American Running Streak Association

An organization highlighted as an example of streak maintenance, where members commit to running consecutively without missing scheduled intervals.

Lead Measures and Lag Measures

Two metrics of goal attainment: lead measures track the high-influence predictive behaviors that drive success, whereas lag measures track the ultimate output or final outcome.

Bluma Zeigarnik

The psychologist who identified that people remember unfinished or interrupted tasks significantly better than completed ones.

Zeigarnik Effect

The psychological phenomenon where individuals experience cognitive tension over an unfinished task, causing interrupted or incomplete tasks to be recalled better than finished ones.

Cliffhanger

A media narrative device that utilizes the tension of unfinished storylines (exemplified in shows like Serial, Making a Murderer, and The Sopranos) to compel audience return.

Negativity Bias

The cognitive tendency for human attention to be drawn more strongly to negative stimuli than positive stimuli and to maintain focus on negative events for longer durations.

Emotional Contagion

The psychological risk of emotions spreading across users, accelerated by algorithmic feeds prioritizing upsetting or angering content like negative reviews, trolls, complaints, and political rants.

Operant Conditioning

A behavioral learning framework where delivering a reinforcer increases the likelihood of a specific behavior recurring.

Fixed Ratio (FR) Schedule

An operant conditioning schedule in which reinforcement is delivered consistently after a specified, unvarying number of responses (e.g., every 5 responses).

Variable Ratio (VR) Schedule

An operant conditioning schedule in which reinforcement is delivered after an unpredictable number of responses that averages out to a set target (e.g., on average every 100 slot plays).

Fixed Interval (FI) Schedule

An operant conditioning schedule where the first response is reinforced only after a specific, predetermined amount of time has elapsed (e.g., every 5 minutes).

Variable Interval (VI) Schedule

An operant conditioning schedule where reinforcement is provided following unpredictable durations of time that average around a set interval (e.g., on average every 5 minutes).

Cumulative Response Curves (Reinforcement Schedules)

The characteristic response patterns produced by reinforcement schedules: FR produces a stepped pattern with post-reinforcement pauses; FI creates a scalloped curve; VR generates a steep, steady response rate; and VI produces a moderate, uniform response rate.

Berns et al. (2001) fMRI Study

A neuroimaging experiment with 25 participants testing water and juice delivery that demonstrated reward-related brain regions show a significantly greater BOLD response to unpredictable stimuli than predictable stimuli.

Nucleus Accumbens (NAC)

A core reward-related brain structure shown via fMRI in the Berns et al. study to exhibit heightened activation when receiving unexpected or unpredictable rewards.

Facebook 'Like' Button

A social reward mechanic introduced in 2009 that leverages unpredictable feedback intervals to incentivize users to continually check their notifications.

Social Hooks

Digital engagement mechanisms, such as activity notifications and tagging alerts, engineered to draw users back onto a platform.

Short-Term Gaming Rewards

Immediate in-game incentives—such as points, coins, visual effects, and new options—that provide quick bursts of reinforcement.

Near Wins

Outcomes where a player almost achieves success, functioning as an exceedingly potent motivator that encourages persistent play.

Zone of Proximal Development (Gaming)

The balanced difficulty range applied in game progression where early levels require lower skill to allow quick leveling up, maintaining optimal engagement and mastery.
