Quiz(32 questions)
1. What type of reinforcement schedule reinforces a behavior after a fixed number of responses?
Terms in this Study Set(32)
Types of Reinforcement Schedules(16)
Fixed-Ratio Schedule
Reinforces a response after a specified number of responses. Examples: Getting $10 for every 5 miles run.
Variable-Ratio Schedule
Reinforces a response after an unpredictable number of responses. Examples: Slot machines pay out after varying amounts of plays.
Fixed-Interval Schedule
Reinforces a response after a specified time has passed. Examples: Getting paid every 2 weeks.
Variable-Interval Schedule
Reinforces a response at unpredictable time intervals. Examples: Checking email for a message that arrives at varying times.
True or False: Fixed schedules produce a steady response rate.
False: Fixed schedules produce a post-reinforcement pause after reinforcement.
Comparison of Fixed-Ratio and Variable-Ratio
Fixed-Ratio: Predictable responses; Variable-Ratio: Unpredictable responses. Variable-Ratio yields higher rates.
Fill in the blank: _____ schedules produce a higher response rate than fixed schedules.
Variable schedules.
Cause → Effect: Why does Variable-Interval lead to steady responses?
Unpredictability keeps participants responding consistently.
Example of Fixed-Interval Schedule
A worker receives a paycheck every Friday for their work during the week.
Example of Variable-Ratio Schedule
Gambling on a slot machine; wins are unpredictable but frequent.
What happens after reinforcement in Fixed-Ratio?
A post-reinforcement pause occurs.
Comparison of Fixed-Interval and Variable-Interval
Fixed-Interval: Set time; Variable-Interval: Random time. Variable-Interval promotes continuous responding.
True or False: A Fixed-Ratio schedule is more effective than a Variable-Ratio schedule.
False: Variable-Ratio typically produces faster rates of response.
Variable-Ratio: Example in Real Life
Playing a lottery where the winning number is drawn after an unpredictable number of entries.
Characteristics of Fixed-Ratio Schedules
- Clear response requirement - Predictable - Post-reinforcement pause often occurs.
Characteristics of Variable-Interval Schedules
- Random timing of reinforcement - Steady response rate - Difficult to predict when reinforcement will occur.
Effects and Applications(16)
Effect of Fixed-Ratio Schedule
Reinforcement occurs after a set number of responses. Example: Getting $5 for every 10 miles driven.
Variable-Ratio Schedule Impact
Reinforcement after unpredictable number of responses. Example: Slot machines pay out after a random number of plays.
Fixed-Interval Schedule Explained
Reinforcement after a specific time period. Example: Receiving a paycheck every two weeks.
Variable-Interval Schedule Outcome
Reinforcement after varying time intervals. Example: Checking emails and receiving responses at unpredictable times.
True or False: FR schedules create rapid response rates.
True. Fixed-Ratio schedules lead to high rates of responding until reinforcement is received.
Key result of VR schedules
High, steady response rates without pauses. Leads to unpredictable rewards.
Cause of higher motivation in VI schedules
Uncertainty of reinforcement timing keeps participants engaged longer.
Difference between FI and VI schedules
FI: fixed time; reinforcing after specific intervals. VI: variable time; reinforces at random intervals.
Example of FI in real life
Payday every month, leading to increased work effort as payday approaches.
Effect of FR schedule on behavior
Produces high response rates with pauses post-reinforcement.
Variable schedules vs. fixed schedules
Variable schedules lead to more consistent behavior; fixed schedules can cause expectations.
Impact of schedule on extinction rate
Variable schedules typically resist extinction better than fixed schedules.
Real-life application of VI schedule
Classroom pop quizzes encourage consistent studying without predictable test dates.
Comparison of FR and VR effectiveness
VR often yields higher and more consistent response rates than FR.
Fill in the blank: ______ schedules produce lower response rates than VR schedules.
Fixed schedules.
Example of VR in everyday life
Gambling; you never know when the next win will occur, encouraging play.
