Crossmodal semantic priming
When the first word is presented auditorily, and the second word is presented visually, the task is crossmodal. Semantic priming is an effect that explained with the following example.
When subjects are asked to name or to make a lexical decision on a visually presented word (e.g. cat), they react faster when they have just been presented with a semantically or associatively related word (e.g. dog) than when there is no semantic or associative relation between the two words (e.g. map).
