dual coding

Well I'm not sure I completely understand this theory, but I do know that many advertisements use this technique very effectively. Blue squares make us think of Nationwide insurance. Bobble hula girls that go on the dashboard of your car make me think of Hardee's commercials. The Postal Service songs remind me of UPS. Some of these ads are very effective and some are not. Some of the dual coding comes off obnoxious and annoying. This can accomplish the opposite of what the commercial is meant to do.
