Final answer:
Neurological studies have shown brain development patterns consistent with Arnett's theory of emerging adulthood.
Step-by-step explanation:
Neurologically, there is support for Arnett's theory of emerging adulthood. Neuroimaging studies have shown brain development patterns consistent with Arnett's theory.
For example, Casey et al. (2005) found that the prefrontal cortex, a region associated with higher-order cognitive functions, continues to develop during emerging adulthood, supporting Arnett's idea that this period is a time of increased cognitive abilities and decision-making.
