[Manifest anxiety, noise, and serial reaction performance (author's transl)]

If high anxiety subjects (HA) measured by MAS have higher chronic anxiety or more sensitivity to noise stress than low anxiety subjects (LA), it is hypothesized that HA's performance decrement under noise will be markedly shown. Ten HA and 10 LA performed 4-choice serial reaction tasks under white noise (95 dB) and control (65 dB) conditions. (a) Results were follows: In LA, the noise increased error response, but HA was not affected. (b) The state anxiety score (self report measures) of LA increased under noise condition, but in HA, this increment was statistically nonsignificant. These results suggest inconsistent relationships between types of stress and personality trait anxiety (MAS).
