Lesson 1: Differentiating Reinforcement & Punishment
The Incentive Challenge
Scenario A
"For every correct answer on this pop quiz, you receive a piece of premium chocolate."
Scenario B
"If the class averages above 80% on this quiz, tonight's homework assignment is cancelled."
Question: Both scenarios increase your motivation to study. Are they both "reinforcement"? Why or why not?
The Behavioral Matrix
Reinforcement
Goal: Increase a behavior.
Positive (+): Adding a stimulus to increase behavior.
Negative (-): Removing a stimulus to increase behavior.
Punishment
Goal: Decrease a behavior.
Positive (+): Adding a stimulus to decrease behavior.
Negative (-): Removing a stimulus to decrease behavior.
The "Negative" Trap
In behaviorism, "Negative" does not mean "bad." It simply means subtraction.
Negative Reinforcement
Taking away something annoying (like a loud alarm) to encourage a behavior (waking up).
Negative Punishment
Taking away something liked (like phone time) to discourage a behavior (missing curfew).

Vignette Frequency Stimulus Action Classification Explanation Case #001 (Marcus) Decrease Removed Negative Punishment (NP) Recess (preferred activity) was removed to decrease shouting behavior. Case #002 (Sarah) Increase Added Positive Reinforcement (PR) A gold star was added to increase the behavior of finishing work. Case #003 (Leo) Increase Removed Negative Reinforcement (NR) The aversive stimulus (anxiety/the assembly) was removed, increasing the behavior of going to the nurse. Case #004 (Jamie) Decrease Added Positive Punishment (PP) Chores (aversive task) were added to decrease kicking behavior.
Teacher Insights & Sample Responses
Q1: Why is Leo's behavior reinforcement?
Reinforcement is defined strictly by its effect on behavior , not the "feeling" of the stimulus. Because Leo's behavior of going to the nurse's office increases in the future, it is reinforcement. It is negative because the removal of an unpleasant state (anxiety/assembly) is what triggered the increase.
Q2: Negative Punishment Sample Scenario
"A high school student uses their phone during a silent reading block. The teacher takes the phone for the remainder of the period (removal). The student stops using their phone during that block (decrease in behavior)."
Common Misconceptions to Address
NR vs. Punishment: Many students think "Negative Reinforcement" means punishment. Emphasize that Reinforcement always means "making the behavior happen more."Subjective Value: What is a "reward" for one student (e.g., getting a sticker) might be a "punishment" or neutral for another. Reinforcement is only confirmed post-hoc (after we see the behavior change). Ratio Mechanics Slides Ratio Rhythm
Lesson 2: Mechanics of Ratio Schedules
Ratio = Responses
Cycle = Repetition
The Slot Machine Paradox
Worker A
"I get paid $5 for every 10 widgets I assemble. Exactly every 10."
Gambler B
"I might win on the 1st pull, the 50th, or the 3rd. I never know when."
Who works faster?
Who keeps working longer if rewards stop?
Fixed Ratio (FR)
Predictable
The Rule
Reinforcement is delivered after a set number of correct responses.
The Pattern
"The Post-Reinforcement Pause"
Fast responding, then a brief break after reward.
Example
"Complete 5 math problems to earn 2 minutes of iPad time." (FR 5)
Variable Ratio (VR)
Unpredictable
The Rule
Reinforcement is delivered after an average number of responses.
The Pattern
"The High & Steady Rate"
Consistent, fast responding. No pauses!
Example
"The teacher praises the student *on average* every 10 times they raise their hand." (VR 10)
FR vs VR: Strategic Selection
Best for Acquisition
Use Fixed Ratio when a student is learning a brand new skill and needs to know exactly when the reward is coming.
Best for Maintenance
Use Variable Ratio to make a behavior last long-term and prevent the student from stopping work the moment you leave.
Key Pro-Tip:
"Variable schedules are more resistant to extinction."

Experiment Beta: Variable Ratio (VR 3)
Procedure: The reward comes on an average of 3. Roll a die (or your teacher will shout out numbers). If the number is 1-3, draw that many tallies then reward. If 4-6, draw that many. No mandatory pauses. Draw 15 marks total.

Exp Alpha: Fixed Ratio (FR 3)
Expected Observation
"The 2-second pause felt frustrating and artificial. I found myself rushing through the 1st and 2nd tallies just to get to the 3rd, even though I knew a break was coming. This perfectly illustrates the 'Post-Reinforcement Pause' —the tendency to stop briefly after a fixed reward before starting the next 'run' of work."
Real-World Link (FR 10)
"A teacher might say: 'After you write 10 neatly formed letters, you can pick a sticker from the bucket.' This is FR 10 because the requirement never changes. It builds confidence in the student because the path to the reward is 100% predictable."
Exp Beta: Variable Ratio (VR 3)
Expected Observation
"My speed was much more consistent. Because I didn't know exactly when the next 'win' was coming, I kept working at a steady pace. There was no urge to pause after a reward because the next one could be only one tally away! This is the 'High and Steady' rate of response seen in VR schedules."
Real-World Link (Maintenance)
"A VR schedule is used for maintenance because it makes the behavior resistant to extinction . If a student is on an FR schedule and doesn't get a reward when they expect it, they quit immediately. If they are on a VR schedule, they are used to 'dry spells' and will keep working much longer."
The Big Takeaway
When to Use FR
During Acquisition . Use it when the student is first learning. High predictability reduces frustration during the difficult early stages of learning.
When to Use VR
During Maintenance . Use it when the skill is mastered but needs to be performed consistently without constant oversight.

Interval Timing Slides The Clock Factor
Lesson 3: Mechanics of Interval Schedules
Interval = Time
Timing = Everything
The Cramming Curve
"When you know a big test is on Friday, when do you do most of your studying?"
Monday - Wednesday: Very little.
Thursday Night: MASSIVE SPIKE!
Time Passed
Response Rate
The "Scalloping Effect"
Fixed Interval (FI)
By the Clock
The Requirement
Reinforcement is delivered for the first response after a set amount of time has passed.
"Check your grades every Friday at 3:00 PM."
The Problem
"The Scallop Pattern"
Students stop working immediately after the reward and only start working hard again right before the next interval ends.
Variable Interval (VI)
Unpredictable Time
The Requirement
Reinforcement is delivered for the first response after an average amount of time.
"Pop Quizzes! They could happen at any time during the unit."
The Result
"Steady and Consistent"
Because the student doesn't know when the check-in is coming, they keep a moderate, consistent level of performance at all times.
Practical SPED Application
Use Variable Interval (VI) for:
"On-Task" behavior (staying in seat)
Social engagement during recess
Quiet voice levels
VI creates "persistence."
"I never know when they're looking, so I better keep doing it!"

Target: On-Task Reading
The Problem: Leo is on an FI 10 (Fixed Interval 10-minute) schedule. Every 10 minutes, if he is reading, he gets a "Reading Token." You observe that for the first 8 minutes, he stares at the ceiling, then frantically reads for the last 2 minutes.
Identify the Phenomenon
Why is he doing this? Use the technical term from today's slides.
The VI Solution
Propose a VI 10 schedule. How would you explain the timing to Leo?
Predicted Outcome
How will his reading behavior change after switching to VI? Draw or describe the expected trend.

Target: Safe Body in Hallway
A student named Maya struggles to keep her hands to herself during a long walk to the cafeteria (4 minutes). You want to use an Interval Schedule because it's a duration-based behavior.
Choice: FI vs VI?

Variable Interval
Interval Length
Define the time (e.g., VI 30 seconds).

Teacher Version
Case 01: On-Task Reading (Leo)
Identify the Phenomenon
"This is the Scalloping Effect . Leo has learned exactly when the reward is coming, so he conserves energy and only performs the behavior right before the deadline. This is a classic weakness of Fixed Interval schedules."
The VI Solution
"I would switch to a VI 10 . I'd tell Leo: 'I'll be checking in on your reading randomly. It could be in 2 minutes, or it could be in 12, but it averages out to every 10. If you're reading when I check, you get a token!'"
Predicted Outcome
Students should describe or draw a steady, straight line of responding rather than the curved "scallop" line. Responding will be consistent across the entire reading block.
Case 02: Maya's Hallway Transition
Best Selection
Variable Interval (VI 30s - 1m)
Maya needs to maintain the behavior constantly for a duration of time. A variable schedule prevents her from "acting out" between predictable checks.
Justification Logic
"A Ratio schedule (rewarding per step) is impractical—the teacher can't count every step. An Interval schedule is better because it focuses on the passage of time. Variable is superior to Fixed because Maya might keep her hands safe for the 4-minute walk if she thinks the 'check-in' could happen at any moment."

The Case of the "Disappearing Skill"
Patient Zero: Alex
Alex learned how to use a sorting bin perfectly last week. He received a Skittle for every single item he sorted. Today, the teacher ran out of Skittles. Alex immediately sat down and refused to sort a single item.

The Designer's Choice
Goal: Speed/Effort
Choose Ratio schedules. These reward "Doing More."
Example: "Finish 5 problems to earn a break."
Goal: Consistency
Choose Interval schedules. These reward "Staying at it."
Example: "Wait patiently for 3 minutes to earn a snack."
Goal: Survival
Choose Variable. It prevents the student from quitting when rewards aren't immediate.
Example: "Surprise desk checks for cleanliness."
Mission: The Behavioral Map
Today, you will design a flow chart that a first-year SPED teacher can use to choose the right schedule. You must consider:
01
Is the skill brand new or already mastered?
02
Do we care about *how much* or *how long*?

Criteria Mastery (4) Proficient (3) Developing (1-2) Decision Logic Flowchart clearly distinguishes between acquisition and maintenance with 100% accuracy in schedule selection. Flowchart distinguishes between phases but may have minor errors in one specific schedule pairing. Decision paths are confusing or do not lead to logical schedule selections. Variable Analysis Deep analysis of "why" a schedule is chosen (e.g., mentioning resistance to extinction or rate of response). Correctly identifies schedules but provides limited justification for the choice. Fails to mention secondary variables (frequency/duration). Technical Terminology Uses all terms correctly: CRF, VR, FR, VI, FI, and Extinction Resistance. Uses most terms correctly; small errors in acronym application. Limited use of technical terms; relies on "rewards" or "punishment." Visual Clarity Professional-grade layout. Arrows and decision points are intuitive for a first-year teacher. Flowchart is legible and organized, though perhaps visually crowded. Messy or difficult to follow; "lanes" of logic cross over or break.

Schedule Thinning
The Vending Machine vs. The Slot Machine
Vending Machine
"I put in $1, I get 1 soda. Every single time. If I put in $1 and nothing happens... I kick the machine and never use it again."
Continuous (CRF)
Zero tolerance for failure.
Slot Machine
"I put in $1... maybe I win, maybe I don't. I'll keep putting in dollars for an hour even if I haven't won once."
Intermittent (INT)
High resistance to extinction.
Schedule Thinning
The Definition
Gradually increasing the response requirement for reinforcement.
Moving from dense to lean reinforcement.
Step 1: Start Dense
FR 1 (Every time) for learning.
Step 2: Increase Requirements
Move to FR 3, then FR 5.
Step 3: Randomize
Move to VR 5 for maintenance.
Resistance to Extinction
If we want a behavior to survive in the "real world" (where rewards aren't constant), we MUST thin the schedule.
Ratio Strain
If you thin too fast (FR 1 to FR 50), the student quits.
Satiation
If you give too many rewards, they lose their value (Full stomach = no work).
Generalization
Behaviors performable in multiple settings without prompts.
Simulation: The Fade
You will now practice the delicate art of "fading" your presence. One of you is the student, one is the teacher.
The Goal:
Get the student to complete 10 puzzles while only checking in 3 times total, without them losing motivation.

Scenario A
The "Ratio Strain" Prevention
Teacher Goal
Thin the schedule from FR 1 (Continuous) to FR 5 for a student learning double-digit addition.
Student Role (Trigger)
If the teacher jumps directly from FR 1 to FR 5, you must throw your pencil and say "This is too hard!"
Success Criteria
The teacher must use a middle step (like FR 2 or FR 3) and provide high-energy social praise even when tangible rewards are absent.
Scenario B
The "Extinction Trap"
Teacher Goal
Move from FI 1-minute (checking in every minute) to VI 2-minute for a student reading silently.
Student Role (Trigger)
You are checking the clock constantly. If the teacher misses a 1-minute mark, you stop reading and look for them.
Success Criteria
The teacher must explain the change beforehand and "catch you being good" at a random 30-second mark to build persistence.
