Prior task failure as a determinant of biofeedback and cognitive task performance

Abstract

In a study of the effects of controllability of outcomes upon behavior in a biofeedback context, 40 college students were assigned to four groups differing in pretreatment: (1) a success-failure group, given false feedback in a fictitious blood-vessel control task for two sessions designed to convey success followed by two sessions of failure feedback; (2) a failure-failure group, given false failure feedback throughout pretreatment; (3) a contingent failure group, receiving actual feedback in a temperature biofeedback task with criteria that assured failure throughout pretreatment; and (4) a control group, given no specific task during this phase. In a subsequent phase, all subjects received actual frontal (forehead) electromyographic (EMG) response training with biofeedback. In analyses of the results, during EMG training, the contingent failure group attained lower levels than the other three groups. By contrast, on a cognitive (anagram) task, interpolated between pretreatment and EMG training, the contingent failure group demonstrated relatively poorer performance than the other groups. The results are discussed in terms of reactance and learned helplessness theories of perceived loss of control in this context.
