Which function of behavior refers to accessing preferred stimuli through positive reinforcement?

The function of behavior that involves accessing preferred stimuli through positive reinforcement is known as tangible. This function is concerned with behaviors that occur in order to obtain or access items, activities, or other reinforcers that are desirable to the individual. When a behavior is reinforced by the presence of a preferred item or activity, it is classified as seeking tangible reinforcement.

For instance, if a child engages in a specific behavior, such as asking for a toy, and that behavior is reinforced by giving them the toy, then the behavior is reinforced as a means to obtain something tangible. This highlights the importance of understanding the underlying motivations behind behaviors, as it allows caregivers and professionals to effectively address and manage behaviors by tailoring interventions to provide appropriate reinforcement.
