Endogenous ERP (Event-Related Brain Potential) Components Associated with Performance in Sonar Operators. 2. Validation of a Performance Prediction Equation

摘要

A cross-validation procedure was applied to a prediction equation. The equation was developed in order to aid in the identification of high level sonar operators. Endogenous event-related potentials (ERPs) were used as predictors and a performance score on sonar simulator tasks was the criterion variable in the equation. A sample (n = 56) of sonar operators was used to create the prediction equation which was then used to predict the performance of a second sample (n = 54). The correlation between the predicted and the actual performance scores for the second (validation) sample was .24 (p<.04). It was concluded that using endogenous ERP components, as predictors of performance, may enhance the process of identifying potentially high level sonarmen. The application of the prediction equation to the selection of aspiring sonarmen could be expected to account for approximately six percent of the variance in performance. Therefore, the use of the prediction equation, in conjunction with the other selection criteria, may aid in the reduction of attrition rates.
