Question

Quizplus · Accepted Answer

The most efficient approach to explore this topic would be to conduct a laboratory observation. In a laboratory setting, the researcher can carefully control the conditions and manipulate the independent variable (e.g. age of the infant), while observing the dependent variable (e.g. response to stranger). This allows for more precise and controlled data collection compared to naturalistic observation or case studies. A double-blind experiment is not necessary in this situation as there is no manipulation of medication or treatment.
