Reactive inhibition is a phrase coined by Clark L. Hull (1951) in his postulate X.A.: Whenever a reaction ''R'' is evoked from an organism there is left an increment of primary negative drive ''I''''R'' which inhibits to a degree according to its magnitude the reaction potential ''S''''E''''R'' to that response (Hull, 1951, p. 74). According to Hull's postulate X.B. inhibition ''I'' dissipates exponentially with time ''t'':.: With the passage of time since its formation ''I''''R'' spontaneously dissipates approximately as a simple decay function of the time ''t'' elapsed, i.e.,Hull's decay formula is somewhat awkward and might give rise to confusion. For example, ''I''R'' does not refer to the derivative of ''I''''R''. A more convenient way of writing the formula would be as follows: : with . is the inhibition at the beginning the time interval (). Note, that if one takes the natural logarithm of both sides one obtains: : where and . The last formula is used in Inhibition Theory. ==References== Hull, C.L.: Essentials of behavior.
