Although investigating metaphors in advertising is gaining in popularity, there are still certain unresolved arguments, such as the interaction between elements of different modalities. This study,composed of three behavioral experiments, aims to identify how verbal anchoring(literal anchoring, metaphor anchoring and unrelated anchoring) influences the processing of pictorial metaphors in advertising, by observing the cognitive and affective indicators, advertising comprehension and advertising likeability. The results showed 1) that metaphors in pictorial modality were recognized more quickly than those in verbal modality, 2) that verbal anchoring facilitated participants ’ comprehending and appreciating of pictorial metaphors and 3) that literally-anchored metaphors with a moderate level of novelty yielded the most favorable cognitive responses. The study not only enriches the existing theoretical framework of multimodal metaphors in advertising, but also proposes an optimal match between pictorial metaphors and verbal elements, for advertisers and manufacturers to design effective multimodal advertisements. 展开更多
