CU-Boulder department of psychology is looking for participants who are excellent at identifying makes and models of modern cars. Brain activity will be recorded with sensors that are held on your head with a device similar to a hair net. Sensors are soaked in a saline solution, so your hair and face will get damp. The procedure is completely safe and painless. Pays $15/hour and a bonus $25 to the highest scoring participant. Must be 18-30 years old, right handed, and male.
