The purpose of this study was to determine the effects of false positive and
false negative feedback upon the self-efficacy and performance of high and low
self-esteem experienced weight lifters. Among a group of volunteers, 65 experienced
male weight lifters were classified as either high or low self-esteem
following administration of the Global Self-Worth Scale (Neemann & Harter,
1986). Each was qualified by the ability to perform a one repetition-maximum
(1RM) bench press between 200 to 350 lbs., which was tested through a series of
trials. Self-efficacy estimates for the 1RM bench press were obtained throughout
the experiment. Trial sessions were accompanied by manipulated feedback,
providing the subjects with either actual, inflated, or deflated values of weights
lifted.
High and low self-esteem subjects performed tasks differently with respect
to the type of feedback received. During the first manipulative treatments, high
self-esteem subjects lifted greater weights after receiving false positive feedback
and lesser weights after receiving false negative feedback. At all times, low self
esteem subjects did not perform differently after the receipt of either false
positive or false negative feedback.
An analysis of the self-efficacy data demonstrated that predictions for
1RM bench press performances were not influenced by levels of self-esteem.
However, both high and low self-esteem subjects predicted that they would lift
greater or lesser weights following the administration of, false positive or false
negative feedback, respectively, and both groups of subjects predicted there
would be no weight differences following administration of actual feedback.
Correlation analyses, conducted to determine relationships between self-efficacy
and performance, indicated that during the first day of manipulative feedback
treatment there was a positive relationship between self-efficacy and subsequent
performance change. Previous performance change and subsequent self-efficacy
change were correlated only for high self-esteem subjects during day 2 of
the treatment. A regression analysis revealed that self-efficacy change was a
better predictor of subsequent performance change than previous performance
change.
In conclusion, false positive feedback increased self-efficacy and
performance of high self-esteem subjects. False negative feedback showed no
significant change for either low or high self-esteem subjects. / Graduation date: 1993
