Identical Twins Hint at How Environments Change Gene Expression
Monica and Erika Hoffman stand barefoot, side by side near a sign that reads “Twin Studies Center” at California State University at Fullerton. Their glasses removed, both have auburn eyes, softly jutted chins, light freckles, and perky noses. Both wear black shirts and small sparkly earrings (Erika’s are flowers, Monica’s, bows). The identical twin sisters turned 39 the day before this lab visit. “You are the 101st twin pair we’ve had in this study,” Nancy Segal, a shrewd, spirited professor in a sequined black hoodie, tells them, as a cluster of graduate students shadow her through the halls. Segal, a fraternal twin herself, is a walking Wikipedia of twin science.

Humans Are Dumb At Figuring Out How Smart Animals Are
If an animal is smart enough, should we treat it like a human? An abstract question, but one that found its way into a courtroom recently. A case bidding for consideration by the New York State Court of Appeals sought to extend the legal concept of habeas corpus — which allows a person to petition a court for freedom from unlawful imprisonment — to cover two privately-owned chimpanzees. The case for giving the chimps a human right like freedom from unlawful incarceration is based on their similarity to humans — they can think, feel and plan, argue the people bringing the case on behalf of the chimpanzees, so shouldn’t they have some guarantees of liberty?

How Same-Sex Couples Divide Chores, and What It Reveals About Modern Parenting
When straight couples divide up the chores of daily life — who cooks dinner and who mows the lawn, who schedules the children’s activities and who takes out the trash — the duties are often determined by gender. Same-sex couples, research has consistently found, divide up chores more equally. But recent research has uncovered a twist. When gay and lesbian couples have children, they often begin to divide things as heterosexual couples do, according to new data for larger, more representative samples of the gay population. Though the couples are still more equitable, one partner often has higher earnings, and one a greater share of household chores and child care.

New Research From Clinical Psychological Science
Read about the latest research published in Clinical Psychological Science: Quantifying Inhibitory Control as Externalizing Proneness: A Cross-Domain Model Noah C. Venables, Jens Foell, James R. Yancey, Michael J. Kane, Randall W. Engle, and Christopher J. Patrick The capacity to resist impulses (i.e., inhibitory control) is an individual difference that affects behavior and health. To better understand the basis of inhibitory control, the authors propose a cross-domain measurement model employing psychometric self-report measures, behavioral-task measures, and brain response measures.

How Social Media Is Hurting Your Memory
Each day, hundreds of millions of people document and share their experiences on social media, from packed parties to the most intimate family moments. Social platforms let us stay in touch with friends and forge new relationships like never before, but those increases in communication and social connection may come at a cost. In a new paper published in the Journal of Experimental Social Psychology, researchers showed that those who documented and shared their experiences on social media formed less precise memories of those events.

Study: Mental conditioning with cute animal pictures can rekindle your relationship
James K. McNulty of Florida State University and his team of psychological scientists were not expecting this. They’d wondered if they could use conditioning to warm the hearts of married couples gone a little cold from numbing day to day life by building associations between spouses’ faces and pictures of adorable puppies and bunnies. “I was actually a little surprised that it worked,” McNulty tells APS, a publication of the Association of Psychological Science.
