Assessment of remote memory: Validation of the television test by repeated testing during a 7-year period

Remote memory for former, one-season television programs was assessed on four different occasions during 7 years. Each test yielded a forgetting curve that was primarily monotonic and linear. In addition, the forgetting curve obtained by the first application of this test in 1973 was largely recapitulated by the three later applications of the test. These findings, together with new information concerning the equivalence of items from different time periods, provide strong evidence that the television test validly measures remote memory.
