Job Performance and Brain Asymmetry: Relevance for Physical Security Personnel,
NAVY PERSONNEL RESEARCH AND DEVELOPMENT CENTER SAN DIEGO CA
Pagination or Media Count:
Conventional paper-and-pencil personnel testing is able to predict academic performance fairly well, but not on-job performance. This may be due to heavy reliance on left hemisphere brain processing verbal, analytical. On-job performance may place heavy demands on right hemisphere brain processing spatial, simultaneous. Three research projects are described, which relate on-job performance to brain asymmetry as measured by visual event related brain potential VERP procedures. The three projects relate VERP measures to aviator performance in F-4 fighter aircraft, antisubmarine warfare trainee performance on a sonar simulator, and enlistee promotions over three years. One of our most consistent findings relate to VERP asymmetry standard deviation SD measure to performance for the personnel tested in these three projects. The asymmetry SDs are least for high performers and greatest for low performers in both front and back brain areas. Relevance in applying brain wave measures to physical security personnel areas is discussed. Future directions of behavioral research using noncontact magnetic recordings from the brain are suggested for physical security personnel assessment. Plans for investigating possible holography applications are also noted. Author
