Refers to a time in middle childhood when the adrenal glands begin producing the adrenal hormone dhea and other hormones that affect cognitive and social development.

The correct answer is 'adrenarche'. This is also the period of early sexual maturation in humans and other higher primates. This period is associated with the development of pubic hair, body odor and acne. The adrenal cortex secretes higher levels of androgens. The development of a new zone of the adrenal cortex, called the zona reticularis, occurs during this period.

The answer is observations and interpreting.
