Board Certified Behavior Analyst (BCBA) Practice Test

What should a behavior analyst increase in order to effectively decrease an inappropriate behavior?

1. Frequency of the inappropriate behavior

2. Value of the aversive stimuli

3. Alternative acceptable behaviors

4. Physical interventions

The correct answer is: Alternative acceptable behaviors

Increasing alternative acceptable behaviors is a fundamental strategy in behavior analysis to decrease an inappropriate behavior. This approach is based on the principles of behavioral interventions, particularly the concept of teaching replacement behaviors. By providing individuals with appropriate alternatives to engage in, you not only address the inappropriate behavior but also reinforce positive actions that can fulfill the same need or function that the inappropriate behavior was serving. For instance, if a child is engaging in tantrums to gain access to attention, teaching them to raise their hand or ask for help in a different way can effectively reduce the occurrence of tantrums. The focus is on providing the person with options that are socially acceptable and that satisfy their needs, which can lead to more adaptive functioning and improved outcomes. This strategy is deeply aligned with the principles of reinforcement and shaping, where the observation and encouragement of positive behaviors can lead to a decrease in undesired behaviors over time. This reflects a proactive approach rather than a purely reactive one. By promoting alternative behaviors, the individual learns new skills, which provides them with better tools for communication and social interaction.
