locus of control and expectation of control in emg biofeedback
abstract
this study examined the importance of cognitions in the feelings
of self-control on task performance and on certain subjective
states, via electromyographic (emg) biofeedback training. subjects
in a "misled” emg feedback group were led to believe that they had
successfully reduced their emg levels (induced cognition of
self control); in actuality, the subjects in the misled group
were yoked to subjects receiving feedback contingent oii their
ovv'n emg levels; thus, the feedback received by the misled
group ’vvas that of their contingent emg feedback counterparts.
the effects of this treatment v/ere explored in relation to
feelings of self control via rotter's i-e scale, emg task
performance during two training trials, state-trait anxiety
levels via the 3tate-tra.it anxiety inventory (stai), and other
subjective states via some self-report questionnaires. these
data were compared to those of the emg group receiving feedback
contingent on their own emg levels and to a control group which
was also yoked to the contingent feedback group, but who were
informed that this was the case.
