摘要：We investigated what the temporal processing is of advertising pictorial metaphors. After presenting "a word of product" and "its advertising pictures," the experiment instructed participants to make a follow-up true-false judgment considering what the picture intended to suggest. A repeated-measures ANOVAs for a 2 (picture type: metaphor, non-metaphor) x 2 (prime-target condition: congruent, incongruent) x 3 (electrode site: Fz, Cz, Pz) experimental condition was conducted on three components, N1 (100-150 ms), N2 (200-300 ms), and LPC (400-600 ms and 600-1,000 ms). The results show that metaphor pictures elicited larger amplitude in N1 (broadly distributed), N2 (frontally biased) and LPC (parietally biased), roughly reflecting an entire process with an initial response to visual onsets, an early recognition of semantic violations and a prolonged reanalysis process of semantic integration. We argue that, different than verbal metaphors, this faster processing occurred due to the involvement of visual pathway.
