A Neuroscience Approach to Optimizing Brain Resources for Human Performance in Extreme Environments

In other Special Operations-specific studies, Hartmann (Hartmann.et al., 2003) examined the predictive validity of several paper and pencil tests in 71 male Norwegian Naval Special Forces candidates. These researchers found only weak correlations between ability tests, personality scales and optimal performance. In comparison, Rorschach approaches to measuring stress tolerance, reality testing, cognition, and social adjustment significantly predicted optimal performance (Hartmann.et al., 2003). These findings suggest that tests which may not be immediately transparent to the participants may provide a more useful approach to selecting optimal performers than do standard questionnaires.

The predictive validity of 7 ability tests, the Big Five, and the Rorschach method administered to 71 male applicants at the Naval Special Forces (NSF) of Norway was evaluated based on pass/fail results in training. The findings showed: (a) small correlations between the ability tests, the Big Five scales, and the success criterion; (b) Rorschach variables measuring stress tolerance, reality testing, cognition, and social adjustment correlated significantly (r =.25 to.48) with pass/fail results in training, and (c) logistic regression analysis revealed that 3 of the Rorschach variables accumulated incrementally in the prediction of training completion when entered after the ability tests and the Big Five scales, thus supporting the merit of using Rorschach variables for predicting NSF training performance

Rorschach variables and Big Five scales as predictors of military training completion: a replication study of the selection of candidates to the naval special forces in Norway.

We tested 140 male candidates at the Naval Special Forces (NFS) of Norway on the Rorschach (Exner, 2003; Rorschach, 1921/1942) and the Norwegian version of the Big Five personality dimensions (Engvik & Føllesdal, 2005). Rorschach variables significantly correlated with training completion (effect sizes of r(e) = .14-.25), whereas none of the Big Five factors or facets did. The combination of Rorschach and Big Five variables framed in the illusory mental health concept provided strong predictive ability. Testing under stress produced slightly higher predictive validity coefficients between the Rorschach variables and pass-fail than under calm testing. The findings support the results of Hartmann, Sunde, Kristensen, and Martinussen (2003), indicating that Rorschach variables and indications of good mental health may be valid predictors of NFS training.
