False

The box of chocolates Karen receives from her grandmother for getting good grades in math is an example of a primary reinforcer, and not as a secondary reinforcer.

Primary reinforcers are biological that are innately satisfying like food (chocolate), drink, and pleasure. Secondary or conditioned reinforcers include money, grades in schools, and tokens. They are the ones that acquire a positive value through an organism's experience.
