THEORYBooks by Hull (74) and Guthrie (62) have brought their respective S-R' theories up to date. A brief article by Tolman (165) gives a pr�cis of his most recent general formulation. MacCorquodale & Meehl (110) have pre sented an elaboration of an earlier paper (112) in which they formalized ex pectancy theory by a set of postulates. They include reinforcement in addi tion to frequency of presentations, Sl-R1-$t, as probably an important determiner of expectancies.' This is the only point in their discussion to which the present reviewers would definitely take exception.Hull's last book (74) is of great significance and will long stand as a me morial to his creative genius. It presents in final form his basic postulates and corollaries. It also contains many ingenious, though often not very rigor ous, applications of these postulates and corollaries, through the derivation of theorems, to most of the factual problems of animal learning. One feature of the system as now presented, in which we naturally concur, is his latest equation for Reaction Potential, SEB = D X V, X K X SHB
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
