Disorders of pubertal timing are common and challenging problems for pediatric endocrinologists. Early or late puberty can have immediate effects on a child's psychosocial well-being and may have long-term effects on adult stature. Much is known about the regulation of the hypothalamic-pituitary-gonadal axis, but the triggers of pubertal onset in the general population remain elusive. This arti...

Retention after rapid overt rehearsal was assessed in two experiments. In the first, 20-word lists were presented as four sets of five words alternating with delay intervals. Recall of items from terminal serial positions was higher when delays were either silent or filled with overt rehearsal than when delays were filled with number subtraction. However, overt rehearsal produced the poorest re...

However, because many more girls present with early than late puberty, we hypothesized that the distribution of the timing of the onset of puberty in girls might have changed. OBJECTIVE/SUBJECTS: The objective of the study was to examine the distribution of the timing of the onset of puberty in normal...
