Studies have shown that fluent, nonhesitant speech is more credible than nonfluent speech, especially in terms of competence and dynamism judgments; nonfluencies appear to have no effect on character judgments and may even lead to favorable sociability judgments (Barge, Schlueter, & Pritchard, 1989;Erickson, Lind, Johnson, & O'Barr, 1978;McCroskey & Mehrley, 1969;Miller & Hewgdl, 1964;Ostermeier, 1967;Scherer, London, & Wolf, 1973;Sereno & Hawkins, 1967).
