Based on prior research, it was hypothesized that heterosexual participants, especially women, who do not perceive themselves as having a strong, close, positive relationship with their opposite-sex parent would be more likely to engage in or attempt to engage in casual sexual behavior (hookups). Also, men were expected to be more satisfied with, and more in agreement with, hookup behavior than women. The results were partially consistent with the hypotheses. Men were more satisfied with and more in agreement with hookup behavior than women. But, opposite sex parent-child relationship quality only affected men’s agreement with the hookup behavior of their peers. Men with lower relationship quality with their mothers agreed more with the hookup behavior of their peers.

Faking emotions is often necessary for both communicating partners. Van Kleef argued that emotional regulation is affected by social norms in society. People regulate their positive or negative emotions instinctively by decreasing or escalating them, as well by managing them or using controlled processes. Therefore, faking is a possible alternative. It is thought that people fake their emotions to mask their genuine feelings, to avoid a painful truth, or in response to social influence such as peer pressure or ex- pectations and to follow social norms. Such influences may cause individuals to fake their emotions simply to make life more comfortable by pleasing others or avoiding social disapproval. […]

Emotions expressed in an interaction may transmit important information to the observer which may be essential for the relationship. Relationships can be classified in terms of their expected benefits. Clark and Mills distinguished between two types of relationships. In the communal type of relationship (between close friends or family members), the interacting partners experience concern for their partner’s wellbeing. Emotional authenticity is important and crucial for the fulfillment of the emotional needs of both parties in the inter- action; it reflects the meaning and the depth of the relationship. On the other hand, exchange relations are those that take place between associates who are together for the purpose of doing business or working (e.g., colleagues). In these cases the other’s emotional well-being may be irrelevant or even a burden. Thus, in exchange relationships people may prefer others to fake emotions rather than display authentic ones.

Our study investigates anger because anger is the most common negative emotion.

Researchers from the University of North Carolina have shown that coupling and sexual behavior are related to our gendered behavior.

What they found is that couples who are showing highly gendered behavior (so highly masculine men and highly feminine women) more often select one another as sexual partners and have intercourse more quickly, compared to couples who show less distinct gendered behavior. The latter are the slowest to have sex and the quickest to break up. The authors argue that the distinct gender differences between highly masculine men and highly feminine women may be needed to incite, and maintain, (sexual) interest in a relationship.

So, your love life may just be the result of how much of a macho man or a girly girl you grew up to be.

According to new research, playing hard to get tests the commitment and quality of any would-be mate. Researchers identified 58 different hard-to-get strategies used, from on/off flirting and being snooty to using voicemail to intercept calls from would-be partners.

“Playing hard to get might be one way that people – women in particular – can test their prospective mate’s commitment and to manipulate their prospective mates to obtain what – or whom – they want,” said the psychologists who carried out the study. “We revealed that the more unavailable a person is, the more people are willing to invest in them.”

In the study, reported in the European Journal of Personality, the researchers carried out four separate projects involving more than 1,500 people, looking at playing hard to get as a mating strategy to see how and why it works. […]

Women used the tactics more than men. That, say the researchers, could be because women are trying to learn more information about a potential mate as they have more to lose in terms of pregnancy. […]

Appearing highly self-confident was the top-ranked tactic, followed by talking to other people and, third, withholding sex.

Pleasantness of an odor is attributed mainly to associative learning: The odor acquires the hedonic value of the (emotional) context in which the odor is first experienced. Associative learning demonstrably modifies the pleasantness of odors, particularly odors related to foods. Experimentally, classical conditioning paradigms (Pavlovian conditioning) have been shown to modify the responses to odors, not only in animals but also in humans (olfactory conditioning).

In olfactory conditioning an olfactory stimulus is the conditioned stimulus that has been paired with an unconditioned stimulus (e.g., taste). For instance, the pleasantness of odors with originally neutral hedonic value was improved after the odors were paired as few as three times with the pleasant unconditioned stimulus, sweet taste. This type of conditioning, where liking of a stimulus changes because the stimulus has been paired with another, positive or negative, stimulus is called evaluative conditioning.

Naturally occurring evaluative conditioning may be important also in modifying the pleasantness of a partner’s body odors (conditioned stimulus) that are encountered initially during affection and sexual intercourse (unconditioned stimulus), because the sexual experiences presumably provide strong, positive, emotional context.

Searches for human pheromones have focused on androstenes, androgen steroids occurring in apocrine secretions, for example, axillary (underarm) sweat, motivated by the fact that one of them, androstenone, functions as a sex pheromone in pigs. However, some 20–40% of adult humans, depending on age and sex, cannot smell androstenone, although their sense of smell is otherwise intact. To date, no convincing evidence exists to demonstrate that any single compound is able to function as a sexual attractant in humans, although several other types of pheromonal effects (e.g., kin recognition) have been observed.

While many studies have explored potential physiological and behavioral effects of the odors of androstenes, we asked a different question: Could an odor (conditioned stimulus) that is perceived during sexual intercourse gain hedonic value from the intercourse experience (presumably a pleasant unconditioned stimulus) through associative learning? While experimental challenges limit human studies of this kind, we approached the question by asking young adults, randomly sampled regarding the level of sexual experience and olfactory function, to rate the pleasantness of body-related (androstenone and isovaleric acid) and control odorants (chocolate, cinnamon, lemon, and turpentine). We compared the responses of participants with and without experience in sexual intercourse and hypothesized that those with intercourse experience would rate the pleasantness of the odor of androstenone higher than would those without such experience. […]

The results suggest that, among women, sexual experience may modify the pleasantness of the odor of androstenone.

With a little practice, one could learn to tell a lie that may be indistinguishable from the truth.

New Northwestern University research shows that lying is more malleable than previously thought, and with a certain amount of training and instruction, the art of deception can be perfected.

People generally take longer and make more mistakes when telling lies than telling the truth, because they are holding two conflicting answers in mind and suppressing the honest response, previous research has shown. Consequently, researchers in the present study investigated whether lying can be trained to be more automatic and less task demanding.

Critics claim that evolutionary biology is, at best, guesswork. The reality is otherwise. Evolutionists have nailed down how an enormous number of previously unexplained phenomena—in anatomy, physiology, embryology, behavior—have evolved. There are still mysteries, however, and one of the most prominent is the origins of homosexuality. […]

If homosexuality is in any sense a product of evolution—and it clearly is, for reasons to be explained—then genetic factors associated with same-sex preference must enjoy some sort of reproductive advantage. The problem should be obvious: If homosexuals reproduce less than heterosexuals—and they do—then why has natural selection not operated against it?

Customers buy a saliva kit online at 23andMe.com, send it in, and the company extracts their DNA from cheek cells preserved in saliva. In its labs, 23andMe then copies the DNA many times until there’s enough to be genotyped. Then, says lesbian scientist Emily Drabant, the DNA is examined for tens of thousands of genetic variants linked to various conditions and traits, and within weeks users get more than 100 reports on diseases, more than 50 reports on traits, more than 40 reports on carrier status, and more than 20 for drug response. […]

The most commonly requested test, Drabant says, is for sexual orientation, a particularly controversial area. […] The company initiated its sexual orientation project about six months ago, and researchers are hoping that tens of thousands of LGBT folks take the genetic test and fill out the accompanying survey — the information from which allows 23andMe to see patterns among, for example, gay men or transgender women. […] As soon as the company has a big enough sample, it plans to make those results public.

The body type that a man finds attractive can change depending on his environment and circumstances, a new study finds: when under stress, for instance, men prefer heavier women.

The study, published in the journal PLoS ONE, reports that when men were placed in stressful situations, then asked to rate the attractiveness of women of varying body sizes, they tended to prefer beefier frames, compared with unstressed men whose tastes skewed thinner. […]

The findings fall in line with evolutionary theories that suggest when resources are scarce or unpredictable, a woman’s thin physique may signal illness, frailty and the inability to reproduce.

The romantic view of romance in Western culture says a very small fraction of people would make a great partner for you, customarily one.

Some clues suggest that in fact quite a large fraction of people would make a suitable spouse for a given person. Arranged marriages apparently go pretty well rather than terribly. […]

It seems we overstate the rarity of good matches. Why would we do that? One motive would be to look like you have high standards, which suggests that you are good enough yourself to support such standards. But does this really make sense? In practice, most of the ways a person could be especially unusual such that it is hard for them to find a suitable mate are not in the direction of greatness. Most of them are just in various arbitrary directions of weirdness.

Since I had spent many years in self-destruct mode, I wanted to use my need for sexual connection to help others. Finally, I had my answer: working as a sex surrogate. […]

A sex surrogate is a therapist who helps people overcome their bedroom dysfunctions. Yes, it involves sleeping with strangers, but unlike prostitution, these men weren’t in search of a good time. They were in pain and filled with shame. They had tried everything. Usually, a sex surrogate is a last resort. And over time, they taught me more about intimacy and vulnerability than I could have imagined. […]

So I taught Bruce how to move his hips in a thrusting motion.

Assume that you can’t redistribute happiness or wealth within the marriage. If your spouse is unhappy you will be unhappy and if your spouse is happy you are likely to be happy; happy wife, happy life.

If you can’t redistribute happiness the play to make is to maximize total happiness. Maximizing total happiness means accepting apparent reductions in happiness when those result in even larger increases in happiness for your spouse. If you maximize the total, however, there will be more to go around and the reductions will usually be temporary.

New research shows a simple reason why even the most intelligent, complex brains can be taken by a swindler’s story – one that upon a second look offers clues it was false.

When the brain fires up the network of neurons that allows us to empathize, it suppresses the network used for analysis, a pivotal study led by a Case Western Reserve University researcher shows. […]

When the analytic network is engaged, our ability to appreciate the human cost of our action is repressed.

At rest, our brains cycle between the social and analytical networks. But when presented with a task, healthy adults engage the appropriate neural pathway, the researchers found.

The study shows for the first time that we have a built-in neural constraint on our ability to be both empathetic and analytic at the same time.

Ovulation, Female Competition, and Product Choice: Hormonal Influences on Consumer Behavior

Recent research shows that women experience nonconscious shifts across different phases of the monthly ovulatory cycle. For example, women at peak fertility (near ovulation) are attracted to different kinds of men and show increased desire to attend social gatherings. Building on the evolutionary logic behind such effects, we examined how, why, and when hormonal fluctuations associated with ovulation influenced women’s product choices. In three experiments, we show that at peak fertility women nonconsciously choose products that enhance appearance (e.g., choosing sexy rather than more conservative clothing). This hormonally regulated effect appears to be driven by a desire to outdo attractive rival women. Consequently, minimizing the salience of attractive women who are potential rivals sup- presses the ovulatory effect on product choice. This research provides some of the first evidence of how, why, and when consumer behavior is influenced by hormonal factors.

Ovulation Leads Women to Perceive Sexy Cads as Good Dads

Why do some women pursue relationships with men who are attractive, dominant, and charming but who do not want to be in relationships—the prototypical sexy cad? Previous research shows that women have an increased desire for such men when they are ovulating, but it is unclear why ovulating women would think it is wise to pursue men who may be unfaithful and could desert them. […] Ovulating women perceive that sexy cads would be good fathers to their own children but not to the children of other women.

This article examines cognitive links between romantic love and creativity and between sexual desire and analytic thought based on construal level theory. It suggests that when in love, people typically focus on a long-term perspective, which should enhance holistic thinking and thereby creative thought, whereas when experiencing sexual encounters, they focus on the present and on concrete details enhancing analytic thinking. Because people automatically activate these processing styles when in love or when they experience sex, subtle or even unconscious reminders of love versus sex should suffice to change processing modes. Two studies explicitly or subtly reminded participants of situations of love or sex and found support for this hypothesis.

In most countries it is illegal to buy or sell a kidney. If you need a transplant you join a waiting list until a matching organ becomes available. This drives economists nuts. Why not allow willing donors to sell spare kidneys and let patients (or the government, acting on their behalf) bid for them? The waiting list would disappear overnight. […]

In romantic comedies, each man and woman marries their own true love. In real life, some people settle for second-best, which can lead to lots of trouble. If John and Mary love each other but are married to other people, they will be tempted to leave their current partner and marry each other. But if John loves Mary, while Mary loves her husband more than John, both will stay put.

If promises are binding, if they are cogent ways for people to bind themselves, there must be a reason to do as one promised. The paper is motivated by belief that there is a difficulty in explaining what that reason is, a difficulty that is not often noticed. It arises because the reasons that promising creates are content-independent. […]

To see the difficulty, think of an ordinary case: I have reason not to hit you, in fact there are a number of such reasons: it may injure you, it may cause you pain, invade your body, etc. They all depend on the nature of the action, its consequences and context. Now think of a reason arising out of a promise, say my reason to let you use my car tomorrow. The reason is that I promised to do so. But that very same reason applies to all my promises. If I promise to feed your cat next week, to come to your party, to send flowers in your name to your mother on Mother’s Day, to lend you my new DVD, or whatever the action I promise to perform (or to refrain from) the reason is the same: my promise. Of course, these are different promises. But normatively speaking they are the same, they are all binding on me because they are promises I made, regardless of what is the act promised. This is why they are (called) content-independent reasons. […]

One simple idea is that promises are binding qua promises (or rather that that is the only ground for their binding character of relevance here), and that they are promises because they are communications of an intention to undertake an obligation by that very communication, regardless of their content, regardless of which act or omission they are about. I suggested that there are exceptions; acts that one cannot promise to perform. For example, a promise (given in current circumstances) to exterminate homo sapiens or all primate species would not be binding. One may think that so long as such exceptions are rare they do not undermine the suggestion that promises are content-independent.

Individuals who have their first sexual experience later than average may have more satisfying romantic relationships in adulthood, according to a new study from The University of Texas at Austin. […]

“We still don’t understand precisely why delaying sexual intercourse is correlated with more satisfied adult relationships,” Harden said. […]

Harden also explains that delaying sexual intercourse isn’t always associated with more positive outcomes. In her previous work, she found that teenagers who were sexually active in romantic dating relationships had fewer delinquent behavior problems.
