Textbook
- Operant conditioning: learning from consequences. A behaviour followed by a consequence becomes more or less likely. Skinner, building on Thorndike’s law of effect.
- Reinforcement makes a behaviour more likely; punishment makes it less likely. Positive adds something, negative takes something away.
- Negative reinforcement takes away something unpleasant, so the behaviour increases. It is not punishment.
- Primary reinforcers (food, warmth) need no learning; secondary reinforcers (money, points, praise) are learned.
- Shaping: reinforcing closer and closer approximations of the behaviour you want.
- Schedules: continuous or partial; fixed or variable, ratio or interval. Variable ratio gives the highest, steadiest rate and is the hardest to extinguish.
Lecture, Thursday 8 October
- The 2×2 grid: add and take away across the top, increases and decreases down the side. Draw it before any question on this.
- Time-out is negative punishment: attention is taken away.
- “Will be on the exam”: which schedule an example shows. Slot machine, variable ratio; checking for a text, variable interval.
Where I went wrong
Quiz, 19 October: I called the alarm example positive punishment. The alarm is taken away and getting up increases, so it is negative reinforcement.

Which schedule of reinforcement does a slot machine use?
Variable ratio: a reward after an unpredictable number of responses. It gives the highest, steadiest rate and is the hardest to extinguish.

```How it works
The syllabus holds fourteen chapters, four exams, a reading quiz most weeks and a paragraph on AI, and by October the dates live in four places. Your assistant turns it into a course map and a document per unit, drafts the key terms from OpenStax Psychology 2e, and writes a quiz ten days before each exam.
