This study investigated the use of electromyographic feedback in regulating the frequency of part-word repetitions. Two adult stutterers, one female (Subject A) and one male (Subject B) were employed. The frequency of part-word repetitions during baserate, EMG uV raising, and EMG uV lowering conditions was assessed for Subject B. As hypothesized, results indicate that there was a notable decline in the frequency of part-word repetitions during the EMG uV lowering sessions. However, contrary to the second hypothesis, (i.e. that an increase in EMG uV would correspond with an increase in part-word repetitions) there was also a decline in the frequency of part-word repetitions during the EMG raising sessions.

A fifty-item questionnaire, representing personality attributes related to behaviors used to index the phenomenon of learned helplessness, was administered to 152 undergraduate students. Based upon factor analysis of the results, six subscales were developed to predict latency of response, failures to solve, and trials to task criterion of anagram solving, this being used to index the phenomenon of learned helplessness. The subscales comprised a ninety-item questionnaire given to seventy-seven undergraduate students three days before participation in the experiment proper. The subjects attempted to solve Levine (1971) discrimination problems (designed to be insolvable) and then attempted to solve patterned anagrams. Contrary to the learned helpless model of depression (Miller and Seligman, 1973), depression was curvilinearly related to latency of response and failures to solve in the anagram task. In addition, internal locus of control was linearly related to trials to criterion.
