Audience Size and Trait Anxiety Effects Upon State Anxiety and Motor Performance

Abstract

This study was designed to investigate how a personal disposition factor (trait anxiety) and a situational factor (number of observers) affect state anxiety and motor performance. Thirty high and 30 low trait-anxious (Spielberger's STAI) female subjects were randomly assigned to one of three treatment conditions: alone, two evaluative observers, five or six evaluative observers. Subjects performed 30 massed 10-sec trials on the pursuit rotor task under their assigned treatment conditions and then completed the STAI state anxiety scale. Trait anxiety significantly affected both state anxiety and pursuit rotor performance but no audience main effects or interaction effects were statistically significant. The results were interpreted as supporting some predictions from Spielberger's trait-state anxiety theory while contradicting others.
