Which of the following describes self-stimulation as a function of behavior?

Self-stimulation refers to behaviors that an individual engages in to produce sensory experiences or personal enjoyment without the primary intention of gaining social approval or external reward. Engaging in behavior solely for personal enjoyment captures this concept accurately, as it emphasizes the intrinsic motivation behind self-stimulatory actions. These behaviors can include repetitive motor movements or sensory-motor activities that provide pleasure or comfort to the individual, functioning as a form of self-soothing or entertainment.

The other options describe different motivations for behavior that are not aligned with the function of self-stimulation. Acting out to get peer attention involves seeking social interaction and approval, while making demands for needs reflects an assertive communication strategy. Withdrawing from social interactions indicates avoidance behavior and does not align with the enjoyment aspect of self-stimulation. Thus, identifying self-stimulation as behavior engaged in purely for enjoyment distinguishes it from behaviors driven by external factors or social interactions.
