Final answer:
One of the drawbacks of using naturally occurring events as quasi-independent variables in research is the lack of control over when these events will occur, which complicates the isolation of cause-and-effect relationships.
Step-by-step explanation:
When using naturally occurring events as quasi-independent variables, one of the drawbacks is that B. one has no control over when the event will occur. This is because naturally occurring events cannot be manipulated or controlled by the researcher, which challenges the establishment of causality in a quasi-experimental design.
In naturalistic observation studies, ecological validity is high, but controlling for external variables is difficult. An inability to control the timing of these events can introduce confounding variables and make it challenging to isolate the cause-and-effect relationship between the quasi-independent variable and the dependent variable, thus affecting the research's outcome.
Lurking variables might also influence results, preventing clear interpretations. For instance, the occurrence of a natural event might be associated with multiple changes in the environment, not just the variable of interest. This complicates the task of attributing specific behavioral changes directly to the quasi-independent variable being studied.
