This paper describes six specific techniques that speech communication students may use in rehearsals to improve memory, to increase delivery skills, and to reduce speech stress. The techniques are idea association, covert modeling, desensitization, language elaboration, overt modeling, and self-regulation. Recent research is reviewed that confirms the efficacy of the six methods, showing how they relate to either high or low levels of physiological arousal that are controlled by language processing in the left brain hemisphere or imagery processing in the right brain hemisphere.
