Sensitization is the intentional act of priming someone to notice something.

It is used in military intelligence to get information that may otherwise not have been on a collaborator’s radar. For example, asking locals to note tobacco-related operations, which would have otherwise been filtered out (by selective attention), because intelligence is tracking a relationship between tobacco transportation and arms smuggling.rH1 This is an example of using the frequency illusion intentionally.
