On trials 106-153, the postshift phase, half of the rats in each group were shifted to a reward magnitude opposite to that previously received in Goalbox 1. During preshift, Alley 1 start and running speeds were inversely related to Goalbox 2 reward magnitude. The size of the FE was directly related to Goalbox 1 and Goalbox 2 reward magnitude. During postshift, Alley 1 running were inversely related to preshift Goalbox 1 reward magnitude. The size of the FE was directly related to Goalbox 1 and Goalbox 2 reward magnitude. The results were discussed in terms of Amsel's theory of frustration.67 pages, 1 unnumbered leavesBTDapplication/pdfIn CopyrightLD5655.V855 1977.G885FrustrationReward (Psychology)Thesishttp://scholar.lib.vt.edu/theses/available/etd-07282010-020233/
