The tool below drills that decision using your own notes as the question bank.
WeSolve+ reads the whole document and writes the questions for you
Upload your PDF, photograph your notebook, or point the camera. WeSolve+ writes questions from that material, explains why each answer is right, reads the chapter back to you as a podcast, and remembers every item you missed until you own it.
The tool below is a small browser-only tool and it is not WeSolve+: paste a few lines and text rules turn them into cards on the spot. The real app, the one that uses AI, is behind the link above.
Unit 3 mechanisms, from your own notes
This is a browser-only tool, and that is all it isIt splits the text you paste by rule, and nothing else. WeSolve+ is a different thing entirely: it reads your whole PDF with AI, writes the reasoning behind every question, speaks the chapter back to you, and remembers what you missed so it can return it. Try the real app now, free!
The tool reads what you paste and cuts it into cards by rule. It cannot see your syllabus, so anything missing from the paste stays missing from the deck.
The three mechanism decision, in one move
An involuntary response transferring to a signal is classical conditioning. A voluntary behaviour rising or falling with its consequences is operant. A behaviour appearing after watching someone else perform it is observational. Underline the verb in the scenario, decide voluntary or reflexive, then check what changed around it. That sequence answers most items in the unit.
Classical conditioning is about signals, and the vocabulary is the marks
In classical conditioning the unconditioned stimulus produces the response by nature, and the conditioned stimulus earns the power by pairing. Acquisition, extinction, spontaneous recovery and generalisation describe the life of that pairing. Scenario items grade whether you attach the right label to the right element, so the vocabulary is the skill.
Operant conditioning prices behaviour
In operant conditioning reinforcement makes behaviour more frequent and punishment makes it less, while positive means adding and negative means removing. The exam's favourite trap is negative reinforcement, which strengthens behaviour by taking something unpleasant away. Schedules matter too: variable ratio rewards produce the persistence that slot machines depend on.
Development claims are testable statements, treat them that way
Piaget's stages are claims about what a child can do: object permanence arriving in infancy, conservation later, abstract reasoning later still. Harlow's monkeys chose contact comfort over food, and Ainsworth's separation studies sorted attachment into patterns. Each finding is an experiment with a result, and questions reward citing the evidence rather than the theorist's name alone.
The scenario question rewards the boring answer
When a story fits two mechanisms, the one explicitly present in the text wins. A child imitating a sibling is observational learning even if a reward follows, because the watching is written into the scenario and the reward is inferred. Quote the cue to yourself before answering; the interesting answer is usually the distractor.

What does AP Psychology Unit 3 cover?
Development across the lifespan and learning: classical and operant conditioning, observational learning, Piaget, attachment and related research.
How do I tell classical from operant conditioning?
Classical pairs a signal with an involuntary response; operant changes a voluntary behaviour through its consequences.
What do positive and negative mean in operant terms?
Adding and removing. Positive reinforcement adds something pleasant; negative reinforcement removes something unpleasant; both strengthen the behaviour.
How should I revise Piaget's stages?
As testable claims with signature abilities: object permanence, conservation, abstract reasoning. Scenario questions describe the ability and ask for the stage.
What is observational learning?
Behaviour acquired by watching a model, shown in Bandura's Bobo doll studies, where children reproduced actions they had only seen.
Can I build scenario questions from my own notes?
Yes. Photograph the pages or upload the PDF and the questions stay inside this unit's mechanisms rather than sampling the whole course.
