Electromyographic Response to Evaluative Stress in Test Anxiety
High and low test-anxious subjects performed a challenging tracking task after receiving instructions designed to maximize or minimize their evaluative apprehension. Electromyographic measures of frontalis muscle tension were recorded during the task. Actual tracking performance, subjective tension, and estimates of relative success on the task were also assessed. There were no statistically significant differences between high and low test-anxious subjects on either the physiological or the performance measures. There were, however, significant differences on the two self-report measures, suggesting a primary role for cognitive factors in test anxiety. Highly test-anxious subjects described themselves as more tense, and they more harshly evaluated their own performance.
