An acquired drive, or psychol, is a drive that is not inherited but is learned. An example would be the desire for money or material success. This is probably because it leads to the satisfaction of innate drives. An acquired drive can be positive and lead to success in life (like wealth or position) or negative that can lead a person to a bad situation (alcohol or drug addiction, illicit sex, etc.). Behaviorists call acquired drives secondary reinforcers, they are learned and not innate like primary reinforcers (food, water, shelter).
