We investigated the effects of musical soundtracks on attitudes to figures in a short animated film. In a preliminary study and in the main experiment, subjects saw the film accompanied by one of two soundtracks or with no soundtrack, or they heard one of the two soundtracks alone. In the main experiment, Semantic Differential judgments on Activity and Potency dimensions, obtained for the music, predicted effects of the soundtracks on corresponding ratings of the film as compared to ratings in a no soundtrack condition. As well, ratings on the Activity dimension of the film characters themselves were altered by the soundtracks. It is hypothesized that congruent auditory and visual structure directs the encoding of particular visual features of the film. In addition, associations generated by the music provide a context for the interpretation of the action in the film. As a result, stimulus features and concepts that are initially encoded as disjunctive conjoin in perception and memory.
