Brain Exercises Don’t Live Up to the Hype, Researchers Say
The Wall Street Journal: Computerized brain-training exercises and games, touted for their ability to improve overall cognitive function, may actually only help you get better at the specific game you’re playing.

The Atlantic: Chelsea Clinton made headlines recently as she campaigned for her mother—not for the policy proposals she defended, but for the fact that she did not accompany her not-quite-2-year-old daughter Charlotte to the first day of her Manhattan "school."

Throughout the attack, the college student memorized every detail of her rapist’s face, promising herself that when she took the witness stand against him, “he was going to rot” in prison. Thompson hurried to police the morning after the attack, giving them a detailed description of her rapist, filling in all the characteristics she’d memorized so carefully.

I knew it.” ...
