Research on "Sexual Afterglow" Shows the Lingering Benefits of Sex

Feature Image

Sex is a defining feature of romantic relationships. From an evolutionary perspective, sex is essential for reproduction. Without it, the human species would die off. But some researchers have proposed that sex has a secondary function in humans and other animals whose offspring benefit from the presence of both parents—sex facilitates pair bonding and thus functions to keep couples happily together over time.

Paradoxical Consequences of Maximizing When Choosing the Best Friends

Feature Image

I recently received a Facebook invite to attend a friend’s party. Before indicating whether I would attend, I checked to see who else would be there. I also texted several other friends to find out what their plans for that evening were. I waited until the day of the event to RSVP just in case any other better options came up. In essence, I wanted to know everything there was to know about my different options for socializing for the evening before making a decision (e.g., who will actually show up, which alternative options exist, etc.).

Unleash the Tongue: The Effect of Sex on Self-Disclosure

Feature Image

The sexual behavioral system evolved to motivate reproductive acts. The primary strategy for achieving this goal is to approach a potentially fertile partner, convince him or her to have sex, and engage in genital intercourse. However, human offspring are vulnerable throughout an exceptionally prolonged development period. Hence, in ancestral environments, sexual partners needed to stay together long enough to jointly care for their offspring during the period of maximum vulnerability, thereby increasing the offspring’s chances of survival and future reproductive success.

Salient Multiculturalism Enhances Minority Group Members' Feelings of Power

Feature Image

Members of ethnic minority groups face many challenges in their everyday lives, including subtle and blatant discrimination, and, more broadly, threats to their social identity. Efforts to mitigate such problems and promote intergroup equality frequently involve telling people how they should try to behave toward minority group members.

Hidden Advantages and Disadvantages of Social Class: How Classroom Settings Reproduce Social Inequality by Staging Unfair Comparison

Feature Image

Alice, Marie and Frédérique have been in first grade for 2 months now. Today, their teacher tells them they are going to learn about a new letter and the girls are already impatient. The teacher writes the letter 's' on the board and turns to ask the children: "what sound does this letter make?'' Immediately a small hand goes up. It is Alice’s. Three other hands quickly follow it. Marie and Frédérique, who do not know this new letter, look at the rest of the class as hands go up. They hope they are not the only ones who do not know the sound of this new letter.

How Marriage Gets “Under the Skin” to Benefit Health

Feature Image

Research shows that married people tend to be healthier than both people who have never been married and people who were previously married (i.e., divorced, widowed, or separated). But it’s less clear how or why married people are in better health. Are there biological and psychological advantages of marriage?

Prospective Motor Control in Infancy Is Related to Inhibition and Working Memory

Feature Image

Executive functions are processes that help us to focus on what is important, to remember things, and to plan our daily activities. Finding early markers of executive functioning could help researchers develop interventions for children with impaired executive functioning (Diamond, 2013), but early executive functioning and its emergence in infancy are not yet sufficiently understood.
