Editor's Selections: Visual Noise, Aplysia, and Psychopaths

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

• Livia Blackburne asks what something called "visual noise exclusion" has to do with dyslexia. She classifies the post as "intermediate-advanced," but it's a good concise explanation of this complicated research finding.
• People have been studying learning in aplysia, the sea hare, for decades. Bjorn Brembs has studied this critter himself for 10 years, but never saw one in the wild, until a recent trip to San Diego. There may be a reason that aplysia can learn.
• Christian Jarrett of BPS Research Digest is hunting successful psychopaths. What is a successful psychopath? "...Thanks to their superior self-control and conscientiousness, rather than landing in prison, they end up as company chief executives, university chancellors and Queen's Council barristers. Well, that's the idea anyway."
