Adults high in cognitive complexity are likely to have had:

A) diverse experiences during childhood.
B) more authoritarian parents.
C) limited experiences during childhood.
D) issues with their mental health at some point in their lives.

Cognitive complexity is associated with a broad range of experiences and exposure to diverse perspectives. Therefore, adults high in cognitive complexity are likely to have had diverse experiences during childhood, which would have facilitated the development of their cognitive complexity. The other options, such as having authoritarian parents, limited experiences during childhood, or mental health issues, are not necessarily linked to the development of cognitive complexity.
