Studies of the effects of imagery instructions and other imagery induction on prose learning are included in this progress report. Five experiments were conducted to establish a developmental trend for ability to use imagery-related mediation in whole passage learning. Observations indicate that six year olds are inhibited in paraphrase recall of heard prose when they are asked to illustrate the passages with cut-out figures, but that nine year olds show no imagery effect. After an extensive training session, nine year olds show a positive effect. Adults show a spontaneous positive effect. The results do not appear to require imaginal-visual-spatial explanations. Information gathered in observations suggests the hypothesis that differential attention to and structuring of working-memory content imagery instructions facilitate prose learning. Further research involves various experiments designed to test this hypothesis. (Author/JM)
