The three faces of Eve

Chris Costmore Sizemore died 24 July. Her life story became famous through the book written by her psychiatrists and the subsequent film which told the story of her multiple personalities – Eve White and Eve Black. She later was treated by other psychiatrists and experienced even greater fragmentation of her personality with over 20 ‘alters’. […]

Infant imitation work is wrong
