Definition Positive Reinforcement & Neurobiological Reinforcement
Positive reinforcement occurs when a behavior is followed by a reward, increasing the likelihood of that behavior being repeated. Neurobiological reinforcement refers to the underlying brain processes involved, principally the dopaminergic reward system, which learns to assign value to the effort that reliably precedes a reward.
Definition Intrinsic Motivation & Curiosity
Intrinsic motivation is the drive to engage in activities for their inherent satisfaction, rather than for some external reward. It's linked to the brain's response to novelty and exploration, often governed by dopamine pathways associated with reward and motivation.
Definition Hyperbolic Discounting
Hyperbolic discounting is the tendency to prefer smaller, immediate rewards over larger, delayed rewards. This bias is thought to be linked to the brain's reward system, which is wired to prioritize immediate gratification.
Definition Planning Fallacy
The planning fallacy is the tendency to underestimate the time, costs, and risks of future actions while overestimating the benefits. It reflects the cognitive bias where the brain optimistically projects future outcomes.
Definition Burnout
Burnout is a state of mental, emotional, and often physical exhaustion caused by prolonged stress or overwork. It's associated with decreased productivity and can be linked to reduced activity in brain regions responsible for motivation and emotional regulation.
Definition Commitment Device
A commitment device is a choice you make now that raises the cost of abandoning your own plan later. Behavioral research, from Ulysses contracts to deposit contracts, finds that self-imposed, voluntarily chosen stakes are among the most reliable ways to follow through on an intention.
Definition Psychological Loss Aversion
Loss aversion is a cognitive bias where the pain of losing is psychologically more impactful than the pleasure of gaining. It's rooted in the brain's natural aversion to loss and the strong motivation to avoid negative outcomes.
Definition Social Facilitation & the Köhler Effect
Social facilitation is the long-established finding that the mere presence of other people changes how hard you work at a task. The Köhler effect is its sharper cousin: paired with someone on a task where both of you have to deliver, the weaker performer works considerably longer than they would alone.
Definition The Curiosity Gap & Narrative Transportation
The information-gap account of curiosity holds that curiosity is a felt deprivation, produced the moment you become aware of a gap between what you know and what you want to know, and that it sharpens as the gap narrows. Narrative transportation is what happens once you are inside a story: absorbed readers are measurably more moved by it than informed ones.
Definition Goal Setting & Implementation Intentions
Goal-setting theory finds that specific, moderately difficult goals produce more effort than being told to do your best. Implementation intentions are the follow-up finding: deciding in advance when and where you will act converts an intention into behavior far more reliably than holding the intention alone.
Definition A habit forms as a behavior becomes automatic through repetition in a stable context. The real-world curve is asymptotic and slower than folklore suggests, with a median around 66 days and enormous individual variation, and a single missed repetition does not measurably set the process back.
