Ivan Pavlov is famous for discovering classical (respondent) conditioning. What was the key insight of his research with dogs?

A: Dogs could learn complex problem-solving by trial and error

B: A neutral stimulus paired repeatedly with an unconditioned stimulus comes to elicit a conditioned response

C: Reinforcement following a behaviour increases the probability of that behaviour recurring

D: Animals have an innate capacity for language acquisition

Correct: A neutral stimulus paired repeatedly with an unconditioned stimulus comes to elicit a conditioned response

Pavlov originally studied digestion in dogs but noticed they began salivating at the sight of lab coats — before food was presented. He systematically studied this, pairing a neutral stimulus (a bell) with food (unconditioned stimulus) until the bell alone (conditioned stimulus) produced salivation (conditioned response). This became the foundational model of respondent/classical conditioning.

Edward L. Thorndike's Law of Effect states that:

A: Every action has an equal and opposite reaction in the nervous system

B: Behaviours followed by satisfying outcomes become more likely; those followed by discomfort become less likely

C: The effect of a stimulus depends on its intensity relative to background stimulation

D: Learning is most effective when it produces visible changes in observable behaviour

Correct: Behaviours followed by satisfying outcomes become more likely; those followed by discomfort become less likely

The Law of Effect (Thorndike, 1898) holds that responses producing a satisfying state of affairs in a given situation become more strongly connected to that situation; responses producing discomfort become weakened. This was a precursor to Skinner's operant conditioning and remains foundational to reinforcement-based learning theory and behaviour therapy.

Who is credited with the famous quote "Give me a dozen healthy infants, well-formed, and my own specified world to bring them up in…" and what position does it represent?

A: B.F. Skinner — representing radical behaviourism

B: John B. Watson — representing the extreme nurture position of behaviourism

C: Ivan Pavlov — representing classical conditioning applied to child development

D: Albert Bandura — representing social learning theory

Correct: John B. Watson — representing the extreme nurture position of behaviourism

John B. Watson wrote this in his 1924 book "Behaviourism", arguing that given complete control of the environment, he could train any healthy infant to become any type of specialist — doctor, lawyer, artist, or beggar — regardless of the child's inborn tendencies. The quote epitomises the extreme environmentalist position of early behaviourism and its rejection of innate factors.

The Little Albert experiment, conducted by John B. Watson and Rosalie Rayner, demonstrated that emotional responses such as fear can be classically conditioned in humans.

Answer: True

In 1920, Watson and Rayner conditioned a nine-month-old infant ("Albert B.") to fear a white rat by pairing it with a loud startling noise. The fear then generalised to other white, furry objects. While the study is now considered deeply unethical and methodologically flawed, it was historically significant for demonstrating that human emotional responses could be acquired through Pavlovian conditioning.

What school of thought did B.F. Skinner represent, and what was distinctive about his position?

A: Cognitive behaviourism — he accepted mental events as intervening variables

B: Radical behaviourism — he held that all behaviour, including private events like thoughts and feelings, is subject to the same laws of conditioning

C: Methodological behaviourism — he excluded mental events from scientific analysis

D: Gestalt psychology — he emphasised the whole over the sum of its parts

Correct: Radical behaviourism — he held that all behaviour, including private events like thoughts and feelings, is subject to the same laws of conditioning

Skinner's radical behaviourism differs from methodological behaviourism in that it does not dismiss private events (thoughts, feelings, sensations) — it simply treats them as behaviours occurring within the skin, subject to the same functional analysis as public behaviour. This is a nuanced position: Skinner did not deny inner experience, but analysed it in terms of contingencies of reinforcement rather than mental causation.

What was special about the Skinner box (operant chamber)?

A: It measured brain activity while animals performed conditioned responses

B: It provided a controlled environment where an animal's behaviour could produce measurable consequences, allowing precise study of reinforcement schedules

C: It was the first device to pair a neutral stimulus with an unconditioned stimulus automatically

D: It isolated animals from all external stimulation to study baseline behaviour

Correct: It provided a controlled environment where an animal's behaviour could produce measurable consequences, allowing precise study of reinforcement schedules

The Skinner box (operant chamber) was a controlled chamber — typically containing a lever or key, a feeder, and recording equipment — in which an animal's responses directly produced consequences (food, water, or avoidance of a shock). This allowed Skinner to study how different schedules of reinforcement (fixed ratio, variable interval, etc.) shaped behaviour with extraordinary precision. The device remains a standard research tool in behavioural neuroscience.

What does Morgan's Canon state, and why is it important in comparative psychology?

A: Animal behaviour should be explained using the most complex cognitive process necessary to account for it

B: In no case should an animal's behaviour be interpreted in terms of higher mental faculties if it can be explained in terms of lower ones

C: The canon of parsimony does not apply to complex social behaviours in primates

D: Animal intelligence can be directly measured by the number of trials needed to learn a task

Correct: In no case should an animal's behaviour be interpreted in terms of higher mental faculties if it can be explained in terms of lower ones

Morgan's Canon (C. Lloyd Morgan, 1894) is a principle of parsimony in animal psychology: we should not attribute higher cognitive faculties to explain an animal's behaviour if a simpler psychological explanation suffices. This was a corrective against anthropomorphism — the tendency to over-attribute human-like intentions and reasoning to animals. It influenced the development of behaviourism by encouraging researchers to stick to observable behaviour.
