A social learning theorist would likely argue that this differential reinforcement will likely lead to distinct gender roles for Johnny and Tracey.
First, we need to understand that reinforcement consists of rewarding a behavior with the purpose of having that behavior be repeated in the future. For example, praising your child every time he does his homework is a type of reinforcement.
Differential reinforcement means reinforcing some specific behaviors while not reinforcing others. In the situation we are analyzing here, Johnny is praised whenever he does something generally considered masculine, such as playing with a truck. Tracey, on the other hand, is praised when she does something considered feminine, such as playing with a doll.
From what is described, we can assume Johnny and Tracey's parents would not reinforce the opposite behavior. That is, Tracey will not be praised for playing with a truck nor will Johnny for playing with a doll. That will lead to distinct gender roles for the two of them.
