What These Unit 3 Questions Cover

On the development side: Piaget's object permanence and conservation, Erikson's identity-vs-role-confusion stage, Ainsworth's Strange Situation and secure attachment, and Vygotsky's zone of proximal development. On the learning side: the unconditioned stimulus in Pavlov's setup, extinction and spontaneous recovery, negative reinforcement vs. positive punishment, the variable-ratio schedule, and Bandura's Bobo doll findings.

The Unit 3 study guide lays these out with memory hooks if you want to review first.

Watch Conditioning Happen Before You're Tested on It

The single most-confused Unit 3 topic is conditioning vocabulary. Before drilling more questions, spend two minutes with the classical conditioning simulator — pair the bell with food, watch the NS become a CS, then withhold food and watch extinction. The labels stop being abstract once you've made them happen.

Unit 3 Practice Test — FAQ

What does this Unit 3 practice test cover?

Both halves of the unit: lifespan development (Piaget, Erikson, attachment, Vygotsky) and learning (classical, operant, and observational).

How do I keep classical and operant conditioning straight?

Classical pairs stimuli to create an involuntary response; operant uses consequences on voluntary behavior. Then check: added or removed? Behavior up (reinforcement) or down (punishment)?

All 12 Practice Questions with Answers

Prefer to review instead of quiz? Every question in this set is below — open one to reveal the answer and the reasoning. (The interactive version above shuffles both questions and answer positions, so reading this list first won't spoil a retake.)

1. In Pavlov's experiment, the food that naturally triggers salivation is the:
  • Conditioned stimulus
  • Neutral stimulus
  • Unconditioned stimulus ✓
  • Conditioned response

Why: Food is the unconditioned stimulus (US) — it triggers salivation (the unconditioned response) without any learning.

2. Removing an unpleasant stimulus to increase a behavior is an example of:
  • Positive reinforcement
  • Negative reinforcement ✓
  • Positive punishment
  • Negative punishment

Why: Negative reinforcement increases behavior by taking away something aversive (e.g., a seatbelt alarm stops when you buckle).

3. Which reinforcement schedule produces high, steady responding that is most resistant to extinction?
  • Fixed-interval
  • Variable-ratio ✓
  • Fixed-ratio
  • Variable-interval

Why: Variable-ratio schedules (like slot machines) reinforce after an unpredictable number of responses, driving persistent behavior.

4. In Piaget's theory, object permanence develops during the:
  • Preoperational stage
  • Concrete operational stage
  • Sensorimotor stage ✓
  • Formal operational stage

Why: Object permanence — knowing objects exist when out of sight — emerges in the sensorimotor stage (birth to ~2 years).

5. According to Erikson, the central psychosocial conflict of adolescence is:
  • Trust vs. mistrust
  • Identity vs. role confusion ✓
  • Integrity vs. despair
  • Industry vs. inferiority

Why: Adolescents work to form a stable sense of self — identity vs. role confusion.

6. Bandura's Bobo doll study is best known for demonstrating:
  • Classical conditioning
  • Observational learning ✓
  • Latent learning
  • Operant shaping

Why: Children imitated aggression they had merely watched — evidence of observational learning (modeling).

7. A child agrees that two identical glasses hold the same water, but says the taller, thinner glass has more after pouring. The child lacks:
  • Object permanence
  • Conservation ✓
  • Egocentrism
  • Assimilation

Why: Conservation — understanding that quantity stays the same despite appearance changes — is typically mastered in Piaget's concrete operational stage.

8. In Ainsworth's Strange Situation, a securely attached infant typically:
  • Ignores the caregiver completely
  • Shows distress when the caregiver leaves and is comforted on return ✓
  • Clings and cannot be comforted on return
  • Shows no reaction to strangers

Why: Secure attachment shows as distress at separation but quick comfort at reunion; avoidant and ambivalent patterns look different at the reunion.

9. After conditioning, a bell is rung many times without food until the dog stops salivating. This process is:
  • Generalization
  • Discrimination
  • Extinction ✓
  • Spontaneous recovery

Why: Presenting the CS repeatedly without the US weakens the conditioned response — extinction.

10. A teen who breaks curfew is given extra chores to reduce the behavior. Adding chores is an example of:
  • Negative reinforcement
  • Positive punishment ✓
  • Negative punishment
  • Positive reinforcement

Why: Something aversive is added to decrease a behavior — positive punishment. Negative punishment would remove something desirable, like phone privileges.

11. Vygotsky's zone of proximal development refers to tasks a child:
  • Can already do alone
  • Can do with guidance but not yet alone ✓
  • Will never be able to do
  • Refuses to attempt

Why: The ZPD is the sweet spot between independent ability and potential with scaffolding from a more skilled helper.

12. Days after extinction, the dog suddenly salivates again when the bell rings. This is:
  • Spontaneous recovery ✓
  • Shaping
  • Latent learning
  • Higher-order conditioning

Why: Spontaneous recovery is the reappearance of a weakened conditioned response after a rest period, showing extinction suppresses rather than erases learning.
