Children's task performance under stress and non-stress conditions: A test of the processing efficiency theory

The effects of test anxiety on children's task performance are not well understood. We examined this issue using the processing efficiency theory (PET; Eysenck & Calvo, 1992) as a theoretical framework. High and low trait test-anxious children (N=90) performed a mental-arithmetic task under high and low memory load conditions. Each child performed the task under stressful and non-stressful conditions. Measures of task accuracy and reaction time served as indicators of performance effectiveness and processing efficiency, respectively. Consistent with the PET, processing efficiency, but not performance effectiveness, was detrimentally affected by test anxiety. However, we did not find support for the PET's assumption that state anxiety mediates the test anxiety-task performance relationship. The roles of task demands on working memory (WM) capacity and individual differences in WM capacity as moderators of the relationship between test anxiety and task performance is also discussed.
