Animals Experimental Psychology Psychology animal learning effort response variability variability Response variability may be influenced by multiple factors in the environment as well as an individual’s previous experiences. This study was designed to investigate the effect of hunger drive and effortfulness of response on rats’ response variability in a two-choice lever press situation. Rats were tested for a total of four weeks, Week 1 was considered to be between-groups and Weeks 1 – 4 were combined to test within-subjects data. Variability was measured in three different ways: the number of times the response location changed in a single session, the length of the first group of responses before changing response and the mean length of responses before changing response location. Between-groups data suggest neither hunger nor effort influence response variability in rats. Within-subjects data suggest hunger did not play a role in response variability, however, effort was significant. Variability of response increased when responding required less effort, as illustrated by all three measures of variability: F<sub>changes</sub>(1,14)=10.41, p<.05, <i>d</i>=2.27, F<sub>firstrun</sub>(1,14)=11.54, p<.005, <i>d</i>=1.82, F<sub>meanrunlength</sub>(1,14)=10.95, p<.005, <i>d</i>=1.77. 2012-08-27 English text University of Toledo / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=toledo1333629053 http://rave.ohiolink.edu/etdc/view?acc_num=toledo1333629053 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
