Answer:
cross-sectional
Explanation:
Cross-sectional design: In psychological research, the cross-sectional design is referred to as one of the types of "observational study design". A researcher or experimenter while conducting cross-sectional research or study tends to investigate or study the various exposures and outcomes in the different participants or subjects involved in the research at the same time.
In cross-sectional study design, the participants involved in the study differ in "variable of interest" yet share a few characteristics.
In the question above, the researcher is employing a cross-sectional design to her study.
The answer is "reinforcement".
The behavior comes into contact with contingencies of reinforcement after the model evokes an imitation. The controlling variable for discriminated operant is the new contingencies of reinforcement. This situation explains Controlled Relation, which is considered as the most important property that defines imitation between a model and a similar behavior.
