Comparison of Memory Tests for Environmental Research

Four memory tests were considered for inclusion in a human performance test battery. The tests were administered to 23 Navy enlisted men for 15 consecutive days. Group means, standard deviations, and cross-session correlations were examined. Two of the tests, Interference Susceptibility and Free Recall, met the initial statistical criteria for inclusion in the test battery. However, the other tests, Running Recognition and List Differentiation failed to show sufficient task definition and reliability in their present form. These tests are compared with each other and with previous memory research studies.
