A paper-and-pencil test of simple arithmetic ability was found to be exceptionally well suited for inclusion in a battery of Performance Evaluation Tests for Environmental Research (PETER). Mean performance stabilized after nine days of baseline testing. Variance was constant throughout fifteen days of baseline testing. “Task definition” was high, and “differential stability” was present from the outset. Subjects apparently came to this test with well established differential levels of arithmetic ability. |
