TORONTO—Gay or straight, male or female—everyone is having fewer affairs now than they were in the 1970s. According to a new study presented here today at the annual convention of the American Psychological Association, extramarital (and extra-partnership) sex is way down, and discussion about the topic within couples is way up.
Psychologists at Alliant International University in San Francisco and their colleagues compared survey responses from two large groups of couples, self-categorized as gay men, heterosexual men, lesbians or heterosexual women. About 12,000 people answered the relevant questions in 1975; close to 1,000 participated in 2000. The average length of the relationship at the time of the survey varied between groups, from about four and a half years for lesbians, almost seven years for gay men and about 14 years for heterosexual couples in 1974 to nearly 11 years for lesbians, 13.5 years for gay men and almost 20 years together for straight couples in the 2000 survey.

Do you always use your lucky blue pen on an exam? Maybe you should switch to red.
University of British Columbia (UBC) researchers tested 600 people on detail-oriented tasks (such as proofreading) and creative tasks (such as brainstorming). They did better on the detail-driven tests when the background on their computers was red, and better on the creative tests when the background was blue, according to results published in today's Science Express.
Even if most of us associate red with danger and blue with tranquility, the link between color and cognitive performance isn’t as obvious as it sounds, says study co-author Julia Zhu, an assistant professor of marketing at UBC. "People are very unaware of the different effects of color: They always think blue will help them do better," Zhu tells ScientificAmerican.com. "If the task is requiring detailed attention, go with red, but if it's asking you to think outside the box, blue will help."
