“…(Cook, 1969;Feldstein, Brenner, & Jaffe, 1963;Kasl & Mahl, 1965;Levin, Baldwin, Gallwey, & Paivio, 1960;Mahl, 1956;Pope, Siegman, &Blass, 1970;Ragsdale & Silvia, 1982;Siegman, 1978). Mild to moderate anxiety also produces accelerated speaking tempo, shorter response latencies, and fewer or shorter silences (Feldstein et al, 1963;Fenz & Epstein, 1962;Kanfer, 1958aKanfer, , 1958bScherer, 1981Scherer, ,1982Siegman, 1978;Siegman & Pope, 1965a, 1965b, while high anxiety leads to more pausing, longer latencies, slower tempo, higher fundamental frequency (which is perceived as pitch), a wide range and variability in pitch, and high intensity amplitude (often perceived as loudness) (Cappella, 1985;Cook, 1969;Fenz & Epstein, 1962;Hecker, Stevens, von Bismark, & Williams, 1968;Mahl, 1956;Scherer, 1981;Siegman, 1978). Speaking tempo and latencies conform to th4 inverted-U hypothesis, first accelerating, then declining as anxiety becomes extreme.…”
