Television questionnaire techniques in assessing forgetting in long-term memory.

Two experiments were designed to test methodological assumptions basic to the television questionnaire technique in order to analyze its appropriateness in assessing forgetting in long-term memory. After controlling for confounding variables in the technique as it is presently used, a non-linear function of time period of television program on recognition response to that program's title was found. Reported television viewing habits had a significant effect on recognition score. The relevance of these findings in regard to the quantitative study of retrograde amnesia is discussed.
