This is the third in a series of articles in this journal which considers the shaping influence of film and television on children's spirituality (Rossiter, 1996, 1997). All three are framed within a particular conceptual scheme (discussed in detail in part 1) which sets out to promote theorizing (on the part of teachers and others interested in the question) about a range of possible psychological mechanisms through which film and television can have a spiritual and moral influence. The scheme is theoretical and pedagogical in focus; it is not directly concerned with research on causal links between the watching of film and television and children's thinking and behaviour. This article begins by concluding the discussion in part 2 on the potential influence of feature films and television. Then follows an exploration of the possible spiritual influence of television advertising.
