Neuro-Chemistry
This "feel-good" neurotransmitter is released in the brain's reward pathway whenever you receive a notification, like, or comment.
Dopamine
This psychological term describes rewards given at unpredictable intervals—the exact mechanism that makes scrolling a feed addictive.
Variable Reward Schedule
This 4-letter acronym describes the anxiety or anxiety-like anxiety that peers are having rewarding experiences from which one is absent.
FOMO (Fear of Missing Out)
This type of light emitted by phone screens suppresses melatonin production and disrupts sleep cycles.
Blue Light
This phantom sensation occurs when a user mistakenly believes their phone is vibrating or ringing in their pocket.
Phantom Vibration Syndrome
Social media interactions often mimic the unpredictable rewards of this casino activity, keeping the brain craving more.
Gambling
This design feature allows users to consume content endlessly without a natural stopping point, bypassing the brain's "signal" to move on.
Infinite scroll
This psychological theory explains how users judge their own worth by comparing their real lives to the curated, "highlight reels" of others.
Social Comparison Theory
This hormone, essential for regulating sleep-wake cycles, is delayed when you scroll through social media in bed.
Melatonin
This phrase describes the modern habit of mindlessly scrolling through negative news stories, which triggers a prolonged fight-or-flight response.
Doomscrolling
This stress hormone can spike when users experience "FOMO" (Fear of Missing Out) or online social rejection.
Cortisol
Algorithms are engineered to trigger high-arousal emotions, particularly this specific negative emotion, because it drives the most engagement and sharing.
Anger
Studies show a strong correlation between heavy social media use and a rise in this clinical mood disorder, characterized by persistent sadness and loss of interest.
Depression
Rather than true multitasking, the brain does this rapid shifting of attention when switching between homework and notifications, which drains cognitive energy.
Task-Switching
This British anthropologist's "number" suggests humans can only maintain about 150 stable social relationships—a limit vastly exceeded by social media follower counts.
Dunbar's number
This brain region, crucial for decision-making and impulse control, is still developing in teenagers, making them more vulnerable to digital distractions.
Prefrontal Cortex
This term refers to the feedback loop where an online action triggers a brain reward, which creates a craving, leading to a repeated behavior.
Habit Loop
This term describes the digital distortion where a person begins to view their actual physical appearance negatively based on filtered images online.
Body Dysphormia
Regular, heavy usage of short-form video platforms has been linked to a measurable decrease in this cognitive capacity, needed for reading or deep work.
Attention Span
This is the term for the mental fatigue and exhaustion caused by the overwhelming amount of data and notifications a brain processes daily.
Information overload
Chronic overstimulation from social media can lead to the downregulation of these specific cell receptors, meaning you need more screen time to feel the same level of satisfaction.
Dopamine Receptors
This psychological phenomenon describes our tendency to seek out information that confirms our existing beliefs, reinforced by algorithmic systems.
Confirmation Bias
This term refers to the psychological condition of being overwhelmed by an endless influx of notifications, messages, and content, leading to complete mental burnout.
Digital Fatigue
This specific type of memory, used to temporarily hold and process information, is compromised when the brain is constantly interrupted by digital alerts.
Working Memory
This neuroplasticity concept summarizes how the brain rewires itself: "Neurons that fire together, wire together." Social media effectively rewires the brain to expect this specific speed of gratification.
