Question text
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.
