Do lovers always tease each other? Study shows how couples handle laughter and banter -- ScienceDaily

The researchers observed that provoking others to laugh at you primarily has positive effects: "Women reported more often that they tended to be satisfied with their relationship and felt more attracted to their partner. They and their partners also tended to be equally satisfied with their sex life," Brauer continues. Being afraid of being laughed at, on the other hand, tended to have negative effects: people who have this fear are less content in their relationship and also tend to mistrust their partner. This also has consequences for the partner: men said more frequently that they did not really feel satisfied with their sex life if their partner was afraid of being laughed at.

A heavy working memory load may sink brainwave 'synch' -- ScienceDaily

They suggest that the "coupling," or synchrony, of brain waves among three key regions breaks down in specific ways when visual working memory load becomes too much to handle. "When you reach capacity there is a loss of feedback coupling," said senior author Earl Miller, Picower Professor of Neuroscience at MIT's Picower Institute for Learning and Memory. That loss of synchrony means the regions can no longer communicate with each other to sustain working memory.
