Behavioral Psychology and Choice
Examine the unseen mechanisms that drive human action, from conditioning and environmental cues to cognitive nudges. Bridge empirical behaviorism with philosophical questions of agency, self-control, and moral responsibility.
Like Duolingo, but for Behavioral Psychology and Choice. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
21 levels across 3 sections, about 42 minutes end to end, roughly 8 days at five minutes a day. It moves through Engineering Everyday Action, Choice Architecture and Self-Direction, and The Philosophical Foundations of Agency. It assumes you already know the basics.

Key ideas in Behavioral Psychology and Choice
- Discriminative stimuli signal availability of reinforcement and reliably trigger automated responding
- Environmental cues govern operant behavior far more reliably than internal cognitive resolve
- Removing antecedent cues eliminates the stimulus-response prompt before deliberation can fail
- Hyperbolic discounting devalues future utility sharply over initial delays rather than at a constant rate
- Immediate reinforcers exert disproportionate control over choice compared to distant consequences
- Commitment devices bind future actions to counteract preference reversals over time
- Response effort measures the physical energy and steps required to complete an operant action
- Small increases in physical friction disrupt automatic behavioral momentum and force deliberation
- Higher-friction environments reliably decrease the rate of unwanted target behavior
- Functional assessments classify behavior into escape, attention, tangible, or sensory functions
- The topography or appearance of a behavior does not reveal its maintaining operant reinforcer
- Replacing a habit requires substituting an alternative behavior that serves the exact same function
- Extinction bursts involve a temporary, acute spike in response rate, intensity, and behavioral variability
- Reinforcing the behavior during an extinction burst inadvertently conditions greater persistence
- Spontaneous recovery can occur later even after an extinction burst has successfully subsided
- Unpredictable payout ratios prevent the post-reinforcement pause seen in fixed schedules.
