Four experimental Super 8 mm sound motion picture films were designed and produced for presentation in a 2x2x2 factorial research model to test the effects of mode of response and stimulus conditions in films for preschool children. Subjects were 40 children (22 males and 18 females) in a Headstart Program in San Pedro, California, divided so that there were ten in each treatment condition and five in each age group. Findings revealed a significant different (p.05) in favor of those groups receiving treatments in which an overt response was required. It was also found that the developmental age effected the cueing variable in diverse ways at upper and lower levels of preoperation. The results are discussed in terms of Piaget's construct of the preoperational learner. (Author)
