Document Summary

Positive reinforcement: presenting stimulus after response, which increases likelihood of response (e. g. , praise, ice cream, bonus jewelry ) Negative reinforcement: removing stimulus after response, which increases likelihood of response (e. g. , headache, chores, late fees ) Shaping: reinforcement delivered for successive approximations of desired response: small steps, effective reinforcement, heav early reinforcement, reinforce less and less. Continuous schedule: every time a behavior occurs. Partial schedule: ratio or interval, fixed or variable. Four partial schedules of reinforcement: fixed ratio (fr) fr1- continuous reinforcement (crf)- best for starting new behaviors. Reinforcement occurs after predetermined set of number/ amount of responses; Ratio (number or amount) is fixed ie. every 5 items sold: variable ratio (vr)- high consistent responses. Reinforcement occurs unpredictably; number/ amount changes each occurrence # of average: fixed interval (fi) Reinforcement occurs after predetermined amount of time has elapsed; same amount each time. Interval (time) is fixed ie exam every 2 weeks: variable interval (vi)
