EVALUTION OF SEMANTIC PRIMING 3 task, leading to questions on how the different bodily senses connect to the memories, knowledge, and general information stored in the brain. For example, when you see the word "GIRL", you respond "yes, this is a real English word", but when you see the letters "XLFFE" you respond "No, this is not a real English word". Semantic priming refers to the observation that a response to a target (e.g., dog) is faster when it is preceded by a semantically related prime (e.g., cat) compared to an unrelated prime (e.g., car). Semantic priming for high-dominance exemplars was modulated by the relatedness proportion and, to a lesser degree, by the nonword ratio. The results showed that, for the first evaluation, the depressives presented similar semantic priming to control subjects.
