Final answer:
Without details from the specific study, we cannot categorize the Cohen and colleagues (2015) research as experimental. Generally speaking, experimental research is utilized to make cause-and-effect claims, involving manipulation and control over variables.
Step-by-step explanation:
Without the specific details of the Spotlight on Research study by Cohen and colleagues (2015), the characterization of the research as experimental cannot be confirmed as true or false in this context. However, in regard to experimental research in general, it is true that these studies can allow researchers to make cause-and-effect claims because of the high degree of control they maintain over variables. Experimental research involves manipulation of an independent variable to observe the effect on a dependent variable while controlling extraneous variables, distinguishing it from other types of research such as observational or correlational studies.
