Final answer:
The research questions for the study by Sana, Weston, & Cepeda (2013) are not specified in the provided references, and would require direct access to the study to ascertain. Replication of their study is important for verification and validation of their results in the research community.
Step-by-step explanation:
The research questions for the study by Sana, Weston, & Cepeda (2013) were not directly provided in the given references. It is important to locate the actual study to determine the specific research questions they sought to address. Typically, in research studies, these questions aim to investigate particular aspects of cognitive processes, educational strategies, or learning outcomes. Without the exact study text, we can only speculate based on related literature that their questions might center on educational practices or the cognitive impact of certain behaviors in educational settings.
Replicating research findings is crucial as it allows other researchers to verify and validate the results of a study. This helps to build a stronger foundation of knowledge and can confirm the reliability and generalizability of the original study's results.
