An account was given of the development within the Russian literature of a uniprocess formulation of classical and instrumental conditioning, known as the bidirectional conditioning hypothesis. The hypothesis purports to offer a single set of Pavlovian principles to account for both paradigms, based upon a neural model which assumes that bidirectional(More)
Assimilation theory was employed to generate quantitative predictions relating the ingoing Müller--Lyer illusion to both angle of fin and gap between shaft and fin. Gap sizes were varied from zero to 18 mm in steps of 2 mm, and angles of fins were varied from 30 degrees to 180 degrees in steps of 30 degrees. Five subjects adjusted the length of a comparison(More)
Battery operated laryngoscopes have two types of switching, one of which could cause an external spark. Laryngoscopes normally supply 2.8 volts and 0.67 amps, which theoretically gives ample energy for ignition of a cyclopropane/oxygen mixture. Attempts were unsuccessful to ignite a stoichiometric mixture of 17% cyclopropane in oxygen by breaking resistive(More)
