For Decades, Researchers Have Relied on Infant Looking Times as an Indicator

For decades, researchers have relied on infant looking times as an indicator of the child's interest. Imagine a new body of research robustly showed that infants actually generally look quite randomly and those longer looking times indicates very little about their interest. Which of the following would most appropriately describe the stake of research that involves infants that use looking time as a measure?

A) Researchers who have previously used this method would need to reanalyze their data to see if their results still hold.
B) Researchers who have previously conducted studies using infant looking times would need to redo their experiments with a new measure to assess the validity of their claims.
C) The researchers should not worry about this new set of findings and continue working as they have. Their previous data were statistically significant and should not be invalidated by this robust finding.
D) This is a clear example of theory informing research questions. Researchers should modify how they ask questions related to infants and their interests.
