3. What question did Genie's sleep study raise that puzzled the scientists for years?

Genie's sleep study raised the question of whether a lack of early sensory experiences, such as those experienced by Genie due to her severe isolation and abuse during childhood, can significantly impact the development of sleep patterns and related cognitive functions. Scientists were puzzled by how such extreme deprivation could affect fundamental aspects of human physiology and cognition, leading to further exploration into the links between early experiences, brain development, and sleep regulation.
