Intrauterine Adhesions Following Miscarriage: Look and Learn.

Objective: To examine the incidence of intrauterine adhesions (IUA) following the management of miscarriage in women with previously documented normal uterine cavities.

Methods: We conducted a retrospective cohort study from two fertility clinics with standard practice protocols for evaluating the uterine cavity prior to infertility treatment and following clinical pregnancy loss. A database query and manual chart review identified 144 women with normal uterine cavities who experienced a miscarriage between January 2010 and November 2012 and returned to the clinic for follow-up hysteroscopy.

Induction, overhypothesis, and the origin of abstract knowledge. Evidence from 9-month-old infants.

Human cognition relies on the ability to extract generalizable knowledge from limited evidence. One type of inductive learning, overhypothesis formation, allows learners to make inferences that take them beyond the limits of direct experience, leading to the creation of abstract knowledge. The developmental roots of this ability have yet to be investigated.
