determined by the individual's capacity to perceive 

 beyond its own physical bounds comes into play. 

 n' = K communication-inhibiting or contact-blinding factor. 

 It reflects a psychological property permitting the in- 

 dividual to ignore a contact resulting from n. n' must 

 derive from {d'r'v' /A') factors. See Section XIII, B, 4 

 for further treatment of n' . 

 i = Intensity of action of one individual toward another 



upon contact. 

 a = ^■^ the duration of the refractory period following the 

 contact of a responsive individual with some other 

 individual. Contacts made by an individual while it is 

 in a refractory state have no influence upon its a. In 

 some way the refractory period is a consequence of the 

 intensity of interaction. It is thus the result of the 

 interplay between the action of each individual toward 

 the other. I have, therefore, assumed that the product 

 of these intensities of action represents a first approxi- 

 mation of a proportionality to the duration of the 

 refractory period. 



faa = The frequency with which one individual, while in the 

 responsive state, meets other individuals, who are also 

 in the responsive state. 



/„p = The frequency with which an individual, while in the 

 responsive state, meets nonresponsive ones (i.e., those 

 in the a refractory state) . 



aaa = Refractory period produced in each individual after 

 each of the faa interactions in which it is involved. «„« 

 produces satisfaction. 



cxap = Refractory period produced in the responsive individual 

 after each f^p interaction. a„p produces frustration at 

 least in the sense of being a nonspecific stressor of 

 physiology. 



ocaa = ocap wlth regard to duration. 

 da or 



0W = afaa, the amount of time per unit time spent in satis- 

 fying refractory periods, da represents the consequences 

 of positively affective interaction. 

 Of or 



^(/) = olJ'^j,, the amount of time spent in the frustrating and 

 physiologically stressful state.
