Editor's Selections: Marriage, Rectal Stimulation, and Candyland

Here are my Research Blogging Editor's Selections for this week:

• Bill Yates asks, Do Personalities Converge After Marriage? Or do similar people simply wind up marrying each other in the first place?
• "'Rectal stimulation', you say. Sounds all fun and games, but actually this study is an important one. It's looking at potentials traveling up from the rectum to the brain, and trying to detect them in both the spinal cord and the cortex." Let Scicurious take you on this journey.
• "A study out of the journal Sex Roles took a look at preschoolers' attitudes towards obesity by means of Candy Land and Chutes and Ladders." Yoni Freedhoff covers an interesting new paper at his blog Weighty Matters. Nonshocker! Preschool kids think thinner is better.
