What you'll learn

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.
