Study Shows Limits on Brain’s Ability to Perceive Multifeatured Objects
New research sheds light on how the brain encodes objects with multiple features, a fundamental task for the perceptual system. The study, published in Psychological Science, a journal of the Association for Psychological Science, suggests that we have limited ability to perceive mixed color-shape associations among objects that exist in several locations. Research suggests that neurons that encode a certain feature -- shape or color, for example -- fire in synchrony with neurons that encode other features of the same object.

Small Acts, Big Love
The Wall Street Journal: Chris Kline doesn't like to tell his wife of 17 years, Tara, that he loves her. He prefers to show her—by loading her favorite songs on her phone and warming up her car on cold mornings. While she was away on business recently, he surprised her by painting her home office in her favorite colors, Mardi Gras purple and gold.
