What term refers to environmental factors that can impact client behavior?

The correct term that refers to environmental factors impacting client behavior is "ecological variables." This concept emphasizes the interaction between individuals and their environments, highlighting how the surroundings, including social, physical, and cultural elements, can influence behavior.

Ecological variables encompass a broad range of factors, such as time of day, location, presence of other people, or even specific events that occur in the environment, all of which can contribute to shaping a person's behavior. Understanding these variables is crucial in fields such as behavior analysis, as it allows practitioners to consider how different contexts can affect clients' responses and behaviors.

In this context, while other terms may refer to aspects of behavior or the conditions under which behavior occurs, "ecological variables" specifically captures the idea of environmental factors that can directly impact behavior in a given setting.
