Simple conditioned reflex as an elementary property of the commutive system, 1621. Still unsolved, 1943. Solved with multistable system, 1982. Further observations, 2064, 2490. Still unsolved, with reasons, 2192, 2243.
█
Conditioned reflex might be due to feedback depending on a "match" 2612.
█
Conditioned reflex machine built. 2614. Seems to be original, 2623.
█
List of properties of conditioned reflex for checking theory, 2186.
█
If a variable is repeatedly displaced to a value X, then the system tends to a field
with resting state at X, 2240.
█
Two examples of a system stabilising a variable after the variable has been fixed
repeatedly there, 1826.
█
Forcing a variable in an U.S. repeatedly to one value tends to make the resting state
go towards that value 2500.
█
In a multistable system, if variables are repeatedly forced to certain values they
will tend to become stabilised there, 1943. Improved statement, 2015, 2240.
█
A possible mechanism for the conditioned reflex examined but rejected, 2673.
█
Ignoring the breaks makes an animal seem to have freedom and intelligence; knowing
the breaks makes it a machine (thus reconciling the two aspects)
█
An ultrastable system is immune to a disturbance ß if the U.S. was going to act as
ß anyway, 2689. This gives a new clue to the conditioned reflex, 2691.
█
In some circumstances, not reinforcing a conditioned reflex may give a large response,
2694.
█
Two ways of getting a conditioned reflex: they are closely related, 2695.
█
Mechanism for conditioned reflex of second order, 2699.
█
Conditioned reflex demonstrated on the homeostat, 2747, 2762.
█
When considering the conditioned reflex, consult Woodworth's book, which contains
much material extra to Pavlov's, 2844.
█
Since the decerebrate dog still has abundant dynamic mechanisms, but cannot develop
the more intricate reflexes, we can deduce that the intricate reflexes demand specialised
mechanisms only to be found in the cortex. 2845, 2858.
█
Three ways of 'proving' that a theory of the conditioned reflex is true, 2848.
█
Hebb points out that Pavlov's theory is contradicted by Pavlov's own facts, 2853.
