This document discusses priming and three experiments on priming. It notes that processing is enhanced for stimuli we've experienced before and a stimulus activates related concepts in the brain. The first experiment found that subliminally priming people with the word "rats" increased negative perceptions of a political candidate. The second experiment involved priming participants with numbers or sounds drawn/said in the air to see if they could identify the primes. The third section discusses ways priming can be used, such as through nods, images or objects.
