Meaney studied rats with differing maternal styles - some were naturally nurturing (they licked and groomed their pups constantly), others were less attentive and even neglectful (mother rats placed in stressful environments like isolation had greatly decreased capacity for nurture). What researchers found was that these behavioral traits were passed down to future generations: pups born to neglectful mothers endured stressful childhoods and grew up to become...
