Which of the following is NOT an example of external reinforcement?

External reinforcement refers to factors outside an individual that influence their behavior, typically through rewards or incentives. In this context, social status, money, and goods and privileges are all tangible rewards that can motivate behavior and are considered forms of external reinforcement. They provide individuals with incentives to engage in certain behaviors or to conform to social norms.

On the other hand, emotional intelligence is inherently an internal characteristic. It involves the ability to recognize, understand, manage, and utilize emotions in oneself and others. Unlike the other options, emotional intelligence does not derive from external rewards or societal recognition; instead, it is a personal skill set that influences how one interacts with their environment and manages interpersonal relationships. Therefore, it stands out as not being an example of external reinforcement.
