What occurs as a result of reinforcement?

The correct answer is that the behavior's future frequency increases over time as a result of reinforcement. Reinforcement, in the context of behavior analysis, refers to the process of providing positive or negative consequences following a behavior, which increases the likelihood of that behavior being repeated in the future.

When a behavior is reinforced, it strengthens the association between the behavior and the reinforcing consequence, leading to an increase in that behavior's occurrence. For instance, if a child receives praise (a positive reinforcer) for completing their homework, they are more likely to complete their homework again in the future because the praise has made the behavior more appealing.

Other aspects mentioned in the choices highlight different effects of behavior change, but they do not relate directly to the primary impact of reinforcement. Decreasing behavior or variability and predictability of behavior are not intrinsic outcomes of reinforcement; instead, the primary outcome is the increase in frequency of the reinforced behavior over time.
