Quizplus · Accepted Answer

The variation in sleep patterns among infants of different countries is most likely due to cultural practices, such as differences in parenting practices or nighttime routines. The other choices, such as reflexive responses or innate preprogramming, are less likely to explain the cultural differences observed. Biological influences may play a role in sleep patterns, but the cultural differences in this case suggest that cultural practices are the primary driver of variation.
