An experimental treatment is introduced with the purpose of equating different age-groups with respect to a potentially relevant function. If the treatment results in an assimilation of the behavior of the different age-groups (age- by-treatment interaction), differences in this function are con- sidered as causal for the normally observed behavioral differ- ence. If it does not result in an assimilation of the behavior of the different age-groups (main effect of treatment), differ- ences in this function are considered as irrelevant for the nor- mally observed behavioral difference. The different interpretations of age-by-treatment interactions and main effects of treatment in this kind of research are reasonable only if the experimental treatment actually results in an equalization of the age-groups with respect to the func- tion of interest. As is shown, such a functional equalization can neither be demonstrated nor assumed in many cases. In such cases, studies with either age-group can be used to investigate hypotheses about potentia | Pindex | Conference proceedings 1979 |
