Abstract

The purpose of this study was to evaluate the effectiveness of Alpha biofeedback training, experimenter induced expectancy, and the combination of Alpha biofeedback training with experimenter induced expectancy on precipitating an attitude change as measured by a locus of control scale. Three groups of college students were used.
Student volunteers were solicited to take Levenson's Multidimensional Locus of Control scales as a pre-test. Those who received treatment and completed the study had scores within two standard deviations of the mean on the adult scale as defined by Levenson (1972). The Alpha group alone and the Alpha plus expectancy group received treatment within ten to fifteen days after the pre-test with the post-test immediately following the treatment. The expectancy group received instructions (treatment) immediately after the tabulations of the pre-test scores and randomization to groups. The post-test was administered following a period of ten to fifteen days from the date of instructions. Analysis of variance and Dunnett's (1955) multiple comparison method were used to determine significance. All results with a probability of .05 were considered significant.
