That consciousness undergoes a severe disturbance in the stutterer during his efforts at communication has been noted in a previous study in this series (Lovett Doust and Douglass5). In this study an account was given of the introspections by the stutterer during his attempts to speak and of the clinical observations made of his state of mind at this time. In addition, it was noted that consciousness may be conveniently thought of in terms of a number of "parameters of awareness" and that certain of these parameters are susceptible to objective measurement by psychophysiologic monitors which vary predictably and in temporal relationship with them. Singled out for principal exemplification in that article were the changes undergone in the parameters of attentive and emotional (visceral) awareness during four phases of stuttered speech, as monitored by the oximeter and the cardiotachometer.

But it is not solely during their efforts to speak
