43 free Ivan Pavlov trivia questions with answers — science & nature quiz, new questions added Sep 2026.
Everyone knows Ivan Pavlov as the man who made dogs drool at a bell, but the real story is stranger: a priest's son from Ryazan who quit the seminary for science, won Russia's first Nobel Prize for work on digestion rather than psychology, grew potatoes in his laboratory during the Allied blockade, and wrote to Stalin to say he was ashamed to be a Russian while the state kept funding him anyway. This Ivan Pavlov trivia quiz runs 43 questions across his whole life and legacy: childhood and education, the digestion experiments and the Pavlov pouch, the four-year Nobel nomination saga, the assistant who co-discovered the conditional reflex, the vocabulary of classical conditioning (unconditioned stimulus, extinction, spontaneous recovery), his temperament typology, his run-ins with the Soviet government, and the novels and psychologists his work shaped. Early questions suit students meeting Pavlov for the first time; the last third is for people who have read Todes. Every answer is verified against Wikipedia's articles on Pavlov and classical conditioning, with the exact supporting sentence quoted under each question.

Q 01Following Pavlov's methods, the 'Little Albert' experiment taught a baby to fear which animal?
A white rat
A white rat: a steel bar was struck behind Albert each time he touched it, and his fear soon spread to a rabbit, a fur coat and a Santa Claus mask.
Q 02Pavlov's laboratory produced which fluid, collected from its dogs, as a remedy for indigestion?
Gastric juice
Gastric juice: the dogs kept producing it even though their swallowed food fell out through an opening in the throat and never reached the stomach.
Q 03In which city did Pavlov give his Nobel Prize lecture?
Stockholm
Stockholm: in the lecture Pavlov recalled that Alfred Nobel himself had sent his laboratory a considerable donation about ten years earlier.
Q 04In Pavlov's lab, when did a buzzer have to sound for a dog to learn that it meant food?
Just before the food
Just before the food: a sound played just after feeding failed to condition the dog, because a signal has to predict food rather than follow it.
Q 05What happened to Pavlov's Nobel Prize money after the Bolsheviks took power?
The state confiscated it
The state confiscated it, and in the hungry years that followed, some academicians living in his own building starved to death.
Q 06Which 1924 disaster at Pavlov's laboratory left some of his dogs with long-lasting nervous disorders?
A flood
A flood: rising water forced the dogs to swim from their kennels to the main building, and afterwards some of them lost their conditioned reflexes.
Q 07What did Pavlov call the reflex that made one dog struggle against any restraint in his experimental stand?
The freedom reflex
The freedom reflex: Pavlov overcame it by giving the dog all its food in the stand, setting one reflex against another.
Q 08A dog in Pavlov's lab broke down when it could no longer tell a circle from which figure?
An ellipse
An ellipse: as it was made ever rounder, the once quiet dog began struggling and howling, and it lost even its easy discriminations.
Q 09Which sitcom's prankster conditions a coworker, Pavlov-style, to expect a breath mint on cue?
The Office
The Office: in a 2007 episode, Jim spends weeks training Dwight to expect an Altoid whenever his computer makes a certain sound.
Q 10Pavlov's dogs fed at fixed intervals began drooling on schedule even when a meal was skipped; what was their signal?
The passing of time
The passing of time: the drool arrived at about the usual moment, suggesting that animals carry an inner clock that can act as a signal.
Q 11Which scientist wrote Reflexes of the Brain, the book Pavlov read as a seminarian?
Ivan Sechenov
Ivan Sechenov's book claimed that all mental activity is reflex; Pavlov later turned that 'bold attempt', as he called it, into experiments.
Q 12Pavlov's 'What is it?' reflex, set off by any slight change around an animal, is now called what?
The orienting response
The orienting response: Pavlov noted that it fades when the same new sound keeps recurring, a waning later studied as habituation.
Q 13Pavlov's prize-winning student research project studied the nerves of which organ?
The pancreas
Q 21After the revolution, H. G. Wells found Pavlov's study piled with which crops Pavlov grew in his spare time?
Potatoes and carrots
Potatoes and carrots: food was so short that he fed his family from a vegetable plot he kept beside his laboratory.
Q 22Pavlov said he would regret giving even which lab animal to the Bolsheviks' social experiment?
A frog
A frog: if Bolshevism was an experiment, he said, it wasn't worth one, yet he never emigrated and worked under the regime until his death.
Q 23To which Soviet leader did Pavlov write in 1927 saying he was ashamed to be a Russian?
Joseph Stalin
He was protesting the treatment of Russian intellectuals; remarkably, he kept his laboratory and his freedom.
The pancreas: by then the dazzling animal surgery of his teacher Elias von Cyon had drawn Pavlov into physiology.
Q 14Pavlov graduated from the Medical Military Academy in 1879 with what distinction?
A gold medal
He then won a competitive fellowship for postgraduate work at the same academy.
Q 15Which Bolshevik signed a 1921 decree promising Pavlov better research conditions and extra food rations?
Vladimir Lenin
Vladimir Lenin praised Pavlov's work as vital to the working people of the world, though Pavlov never hid his contempt for Communism.
Q 16Pavlov credited which 17th-century French philosopher with first imagining the idea of the reflex?
René Descartes
René Descartes pictured animals as machines, each action a necessary reaction to something outside them, an idea Pavlov took into the laboratory.
Q 17Pavlov improved Rudolf Heidenhain's small, separated section of a dog's stomach, now known as the Pavlov what?
Pouch
Pouch: Pavlov's version kept its nerve supply, so the small sac responded to eating even though no food ever entered it.
Q 18Soon after it opened in 1890, which St. Petersburg institution invited Pavlov to organise its physiology department?
Institute of Experimental Medicine
Institute of Experimental Medicine: there, in the 1890s, Pavlov did most of the digestion research that later won him the Nobel Prize.
Q 19The institute where Pavlov led physiology for 45 years grew from a station treating which disease by Pasteur's method?
Rabies
Rabies: Prince Alexander of Oldenburg paid for the station out of his own pocket, and later funded the whole institute.
Q 20What did Pavlov call his experiments on dogs that had recovered from surgery before being studied?
Chronic experiments
Chronic experiments let one dog be studied for months or years, where the older 'acute' vivisection killed the animal on the table.
Q 24In 1934, Pavlov sent letters of protest to which Soviet official?
Vyacheslav Molotov
Vyacheslav Molotov received them, yet the state kept supplying Pavlov's laboratory generously in spite of his attacks.
Q 25As he lay dying, Pavlov asked a student sitting by his bed to do what?
Record his final moments
He wanted to leave unique evidence of the subjective experience of the terminal phase of life.
Q 26Pavlov's typology of nervous systems updated the four temperaments of which two ancient physicians?
Hippocrates and Galen
Hippocrates and Galen's types helped him explain why his dogs reacted so differently to the same conditioning, so he sorted them into nervous types.
Q 27Pavlov's term for the body shutting down under overwhelming stress or pain was what?
Transmarginal inhibition
Transmarginal inhibition later helped psychiatrist William Sargant explain the breakdowns of shell-shocked soldiers and, in his view, brainwashing.
Q 28Which childbirth method grew from Soviet techniques built on Pavlov's conditioned reflexes?
The Lamaze method
The Lamaze method: French obstetrician Fernand Lamaze saw the technique in the Soviet Union in 1951 and made it popular back in France.
Q 29In game theory, what does the strategy named 'Pavlov' do after a round goes badly?
Switches to the other move
Switches to the other move: this win-stay, lose-shift rule outperformed tit-for-tat in 1993 simulations because it can correct occasional mistakes.
Q 30What did Pavlov first call the drooling his dogs did at the mere sight of food?
Psychic secretion
Psychic secretion: rather than say a dog drooled because it wanted meat, Pavlov chose to study the flow objectively, as a physiologist.
