TRANSCENDING THE BOUNDARIES
Di e gen app oaches
In Ame ica, he ou pu o wo k in o beha io diso de s in animals, expe imen al

he es ablishmen in 1929 o he Pa lo ian Labo a o y a Phipps Psychia ic Clinic

Bo h, Liddell and Gan used Pa lo ian echniques albei wi h some me h-

Gan , like Pa lo , used he sali a ion e lex and his labo a o y animal was he dog.

Maie and Masse man, on he o he hand, used ins umen al lea ning echniques.
Maie used he «jumping appa a us» ha Lashley (1930) had designed. He ained

back allowing he animal o land on a pla o m whe e i ob ained a ood ewa d. In
con as , he inco ec s imulus boa d was closed wi h a la ch and i he animal jumped
o e i , i did no open and he a ell in o a ne (Maie , 1939).
Masse man used a ask whe e an animal (ca ), in he p esence o a ligh and
audible signal, had o li he lid o a ood ay o ob ain a piece o ood. La e , when
he ca ied o open he ay, his esponse was punished wi h an a e si e s imulus (an
ai blas a he animal’s head o an elec ic shock) (see Masse man, 1943).
Ob iously, he p ocedu al di e ences men ioned abo e helped o disco e new
condi ions p oducing abno mal animal beha io . To he adi ional, di icul disc imina-

he animal’s esponse o insoluble disc imina ions (Maie ) and he punishmen o

This me hodological di e si y also p oduced a wide ange o heo e ical p oposals
ha wen beyond he bounda ies o Pa lo ian b ain physiology and p oposed new

logical concep ions ha con empla ed he animal as a whole and s udied he e ec s
ha hese pa hologies had in di e en physiological sys ems and in hei in e ac ions.
The case o Liddell is in e es ing because he s a ed ha Pa lo ian echnique is
essen ially a me hod o p oducing expe imen al neu osis:
Since all ypes o Pa lo ian Condi ioning de elop in he animal inc easingly

condi ioning and will, i long con inued, lead o emo ional disas e . (Liddell,
1956, p. 81, i alics in he o iginal).
This emo ional igidi y, Liddell assumed, concealed a ense expec ancy. Fo his,
he used Hen y Head’s e m ‘ igilance’. Liddell hough ha when he capaci y o
main aining in ense and un emi ing igilance is exceeded, he pen -up ne ous en-
sion he eby eleased will dis up he ope a ion o he condi ioning machine y and
lead o ch onic s a es o neu osis (Liddell, 1950).

was o he opinion ha hese wo he p inciples depend much upon cons i u ional
p edisposi ions (Gan , 1953).
Masse man’s posi ion was exp essed in ou «psychobiological p inciples o be-

(…) all beha io is undamen ally mo i a ed by he physiological equi emen s

Finally, al hough by he end o he 1950s many psychologis s had come o he

The me hodological and heo e ical di e gence we ha e jus desc ibed was also
