What is NOT a characteristic of behavior?

The assertion that behavior is not permanently fixed is rooted in the understanding of human and animal behaviors as dynamic and adaptable rather than static. Behavior is influenced by a multitude of factors, including environment, experiences, and individual circumstances. Consequently, it can change over time in response to different situations or influences.

In contrast, describing behavior as cyclical or temporary recognizes that certain actions may occur repeatedly or only under specific conditions. Aggressive behavior, while it can be a characteristic of an individual, is also not fixed and can fluctuate based on a variety of internal and external factors. Hence, the notion that behavior is permanently fixed does not align with the contemporary understanding of behavioral psychology, which emphasizes the fluidity and variability of behavior based on context and ongoing experiences.
