AGE AND BEHAVIOR: RESEARCH METHODS - AGE AND TIME OF MEASUREMENT CONFOUNDED - SUBJECT EFFECTS - PRACTICE
It is the opinion here that time of measurement should be defined broadly to include not only states of the physical and social environment but also states of the subject and experimenter as part of the environment. If conditions of measurement are not identical at time 2 and time 1 with respect to the states of subject and experimenter, then longitudinal comparisons involve ambiguity of interpretation.
Practice. Among the more obvious considerations regarding the state of the subject, the one most often emphasized is the effect of practice. The experience of taking a test is expected to have an effect on taking it a second time. The subject knows the test better, he may even look up the answers he missed, and, as important, perhaps, the unknown, anxiety-producing aspects of the test environment may be diminished. In short, the state of the subject is altered by his environmental experiences, independent of his age. Is improvement in test 2 a reflection of true age gains, or of the practice? Would an observed age decrement be even greater had there been no practice?
The role of practice, intrinsic to a repeated measures design, which, in turn, is intrinsic to the longitudinal method, may be overcome experimentally by examining only part of a sample of subjects during the first test period. For the second testing, rather than examine the same subjects again, the other part of the sample, the part not yet tested, is examined. This design is of unrepeated or independent measures. The independent measures design is difficult to execute because it is necessary to start with a well-defined subject pool, to test only half the subjects at time 1, and to be able to locate and test the other half at time 2. If both repeated and independent measures are made concurrently, the practice effect can be estimated. However, even the estimated practice effect will be confounded with other time-of-measurement factors.
