Trait Constellation
Key Achievements
Received the 1904 Nobel Prize in Physiology or Medicine for his work on the physiology of digestion. The presentation speech singled out his surgical technique, which let the same animals be studied over long periods.
From 1902 he turned his laboratory to the objective study of so-called psychical secretion in dogs, the work on conditioned reflexes that occupied him until his death in 1936.
Directed physiological laboratories at the Institute of Experimental Medicine and the Military-Medical Academy in St Petersburg for more than three decades. His students record dozens of co-workers at a time passing through them.
Moments That Reveal Them
According to his student Boris Babkin, when Pavlov first tried to make an isolated stomach pouch with its nerves intact, in about 1893-94, the operation failed nineteen times. It succeeded on the twentieth dog, and the student assigned to the problem was able to finish his thesis.
The episode offers one example of the profile's persistence score: repeated failure on a difficult operation did not end the attempt. Persistence
A collaborator, V. V. Savich, recalled that Pavlov asked him to repeat Bayliss and Starling's secretin experiment, which challenged the laboratory's view that pancreatic secretion was controlled by nerves alone. When it was confirmed in front of him, Pavlov left for half an hour and returned saying, 'Of course, they are right.'
This sits alongside the profile's belief-updating score, which is kept moderate because Babkin also records that Pavlov needed a great deal of proof before changing his mind. Belief Updating
Turning Points
In his Nobel lecture of December 1904, Pavlov spent much of his time on a new line of research rather than only on the digestion work being honoured. He described his decision to treat the dogs' 'psychical' salivation from an entirely objective point of view.
The choice is consistent with the profile's independent-thinking score. Gantt records that friends such as Sherrington and Tigerstedt later urged caution about the new programme, and he continued it anyway. Independent Thinking

V. Savich's 1924 article, N. J. Chistovich's 1904/1925 recollections, Mrs Pavlov's 1946 'Reminiscences', or Pavlov's own tellings (flagged as such where used). Admiring but openly critical in places (the Bechterev polemic, temper, the secretin 'chance' remark, lack of practical classes). Read: Introduction; ch. 2 (Botkin laboratory 1878-90, the thesis delay to 1883, the control-experiment episode, Chistovich's account); ch. 5 (pharmacology and physiology chairs 1890-95, teaching by demonstration, the Pashoutin ballot protest and reprimand); ch. 6 (Institute of Experimental Medicine, chronic 'physiological surgery', organisation of graduate work); ch. 7 (Babkin's own entry 1902); ch. 8 (indifference to rank, the Academy-conference operation, the Bechterev/Gorshkov/Spirtov controversy c.1906-09, Babkin present); ch. 9 (integrity, secretin, punctuality, Dr V. and Savich's intervention, the Pavlov pouch after nineteen failures c.1893-94, concentration); ch. 10 (testing of reported results, creative imagination, 'six months' rule for theories, training of newcomers, watching Babkin's test tubes 1902); ch. 11 (school, invitation to contradiction, laboratory-council proposal, temperament, Chistovich's forceps story); ch. 12 (attitude to co-workers, operations, the 1902 Thompson demonstration); ch. 13 (daily routine 1901-12 and later per Frolov/Logansky, Nobel 1904, the Nobel lecture topic, 1913 frictions).
