Effects of Mixed and Unmixed Criterion Questions. Observational Report No. 7226.
Bond, Jack H.
Incorporated in the media evaluation model developed by the Computer Based Project (Syracuse, N.Y.) is a procedure whereby independent samples are used to obtain baseline responses to cognitive question items. Items from two films are intermixed and presented after showing only one of the films; thus, the sample audience responds to questions from both the unseen film and the film which was seen. This study sought to determine whether the procedure affects the responses of the samples. Statistical analyses are performed on the data gathered from educable mentally retarded (EMR) and normal samples receiving mixed questions sets. This is in contrast to EMR and normal samples receiving questions only on the film seen. The results indicate that there seems to be an effect of mixing items which results in lower scores for EMR children on the criterion items for the film seen than when only items pertaining to the film were asked. One explanation for this finding is that greater respondent frustration can be expected from the mixing of relevant (film seen) and irrelevant (film not seen) items, resulting in a lower number of correct scores.
