What best describes events that take place within an organism's skin or are otherwise only accessible to that organism?

Private events best describe occurrences that take place within an organism's skin or are otherwise only accessible to that organism. This term refers to internal experiences, thoughts, feelings, physiological processes, and sensations that cannot be directly observed by others. For example, an individual's private event could include their thoughts about a specific situation or their internal emotional response to an experience. Understanding private events is crucial in the field of behavior analysis, as it highlights the importance of considering subjective experiences when working with individuals, especially those on the autism spectrum.

Public events, on the other hand, refer to observable behaviors and interactions that can be seen and measured by others. Observable behavior encompasses actions or responses that are evident and can be recorded or analyzed, while external stimuli involve factors or influences in the environment that affect behavior. Therefore, these concepts do not accurately capture the essence of events that are confined to the internal realm of an organism.
