A recent Wall Street Journal/NBC News poll found that 49% of Americans still believe the U.S. economy is in recession, even though we are now in the sixth year of the recovery. […] If investing when others are skeptical has historically been a successful strategy, why don’t more investors do so? […] Taking advantage of the findings discussed earlier requires investing when the economy and market seem to be at their worst, and rebalancing when conditions appear to be the best. This is counterintuitive for many investors, who tend to wait for confirming evidence before acting. This is related to herd behavior, the tendency to follow the crowd with portfolio decisions. Investing when others are skeptical is emotionally difficult but, as we’ve shown, tends to be when rewards are the greatest. [JP Morgan Funds | PDF]

Pham and Schackelford (2013) argued that men with more attractive partners are at a greater recurrent risk of sperm competition because other men are more likely to woo them into having affairs. Therefore, men with more attractive partners have more reason to be concerned about and more likely to engage in behaviour aimed to detect infidelity. The idea that cunnilingus, oral sex performed on a woman, could function to detect infidelity was proposed in a 2006 book, but this study is the first to test this empirically. The idea is that oral sex may allow a man to detect the presence of another man’s semen through smell or taste. […] As side-note I’d like to point out that there is a common misconception often advanced by its critics that evolutionary psychology assumes that everything that people do is somehow an evolutionary adaptation and that evolutionary psychologists cannot or will not acknowledge that some behaviours are simply by-products of other adaptations with no special function of their own. This is a gross misrepresentation of what evolutionary psychology is about and in fairness to the authors of the study they were attempting to actually test whether or not their hypothesis about the adaptive function of oral sex is valid, rather than just assuming it is. It is quite possible that oral sex has no evolutionary function in itself. Humans are a highly sexed species compared to most mammals and engage in many non-procreative sexual acts, perhaps for pleasure alone. Oral sex might simply be a by-product of this interest in sex that humans have. However, if it can be shown that this particular behaviour appears to serve a definite purpose that has an evolutionary history, a reasonable case can be made that it has an adaptive function. […] They found that “recurrent risk of sperm competition” (attractiveness) predicted interest in performing oral sex independently of relationship length, relationship satisfaction, and duration of intercourse. [Psychology Today]

In species where females mate with multiple males, the sperm from these males must compete to fertilise available ova. Sexual selection from sperm competition is expected to favor opposing adaptations in males that function either in the avoidance of sperm competition (by guarding females from rival males) or in the engagement in sperm competition (by increased expenditure on the ejaculate). […] We found that men who performed fewer mate guarding behaviors produced higher quality ejaculates, having a greater concentration of sperm, a higher percentage of motile sperm and sperm that swam faster and less erratically.

Men who had slept with more than 20 women lowered their risk of developing cancer by almost one third. In contrast, men who slept with 20 men doubled their risk of developing prostate cancer.

It has been proposed that kissing, a near-ubiquitous custom among human cultures, may play a significant role in the process of human mate assessment and relationship maintenance. Kissing might aid mate appraisal in humans by facilitating olfactory assessment of various cues for genetic compatibility, health, genetic fitness, or even menstrual cycle phase and fertility. […] It is likely that kissing works to affect initial mate assessment by bringing two individuals into close proximity so as to facilitate some kind of olfactory/gustatory assessment, since olfaction in most mammals, as well as in humans, can play an important role in assessing potential mates. In established relationships, on the other hand, the contact and physiological arousal initiated by continued romantic kissing is likely to also affect feelings of attachment between individuals over time, influencing the release of neuropeptides (including oxytocin and vasopressin), dopamine, and opioids, which have all been variously associated with human pair-bonding.

Religiosity delays initiation of sexual behavior, but the association may be bidirectional, and individuals may become less religious after first intercourse.
This study uses longitudinal data from college students to examine whether 2 aspects of religiosity change before and after first intercourse using multiphase growth curve models. Students’ religiosity did not change in the 6 months preceding first intercourse, but on average they attended services less often and felt religion was less important in the 12 months after first intercourse.

Attributions to God and Satan About Life-Altering Events

In social psychology, revenge is defined as a behavioural reaction toward perceived injustice that aims at re-establishing a (personal) sense of justice by “getting even” and giving wrongdoers what they deserve. The question I will address in this presentation is, what exactly does “getting even” mean? By addressing this question, I will adopt a “social functionalist” perspective on revenge: This perspective highlights the notion that revenge is a goal-driven response that has certain functional aspects, both on the intrapersonal and on the interpersonal level. The “social functionalist” perspective implies that revenge is not the mindless, animalistic impulse that legal scholars and some philosophers sometimes tend to see in it. Revenge has oftentimes been contrasted with law-based retribution by arguing that revenge was irrational, savage, unlimited, unprincipled, and disproportionate, and that the “emotionality” inherent in vengeful reactions overshadowed any rational response. Psychologically, the idea that emotions are irrational is neither useful nor correct. On the contrary, emotions are functional, adaptive, and ecologically rational in that they direct the organism’s attention to important aspects of a situation, and they prepare the organism to respond to problems that arise in social interactions. For example, empirical studies show that anger involves a shift of blood away from the internal organs towards the hands and arms, and it increases one’s sensitivity toward potential injustices and the moral implications of other people’s actions. Of course, anger can also trigger disproportionate retaliatory behaviours, but this does not mean it is inherently “irrational.” Most behavioural systems that the human organism is equipped with are “irrational” in that they may be incompatible with logical, deductive reasoning and a stringent cost-benefit analysis of gains, risks, and losses, but they are nevertheless functional in that they enable us to deal with complex problems and to make useful decisions under uncertainty. Revenge belongs to the human behavioural system just as communication, competition, or helping does; and just as these systems, it has important societal and individual functions. [Individual and social functions of revenge | PDF]

This article investigates whether acts of displaced revenge, that is, revenge targeted at a different person than the original transgressor, can be satisfying for the avenger. We assume that displaced revenge can lead to justice-related satisfaction when the group to which the original transgressor and the displaced target belong is highly entitative. Two experimental online studies show that displaced revenge leads to less regret or more satisfaction when the transgressor and the displaced target belong to a group that is perceived as highly entitative. Study 3 shows that avengers experience more satisfaction when members of the transgressor group were manipulated to be both strongly interconnected and similar in their appearance. Results of an internal meta-analysis furthermore corroborate the notion that displaced revenge leads to more satisfaction when the transgressor group is highly entitative. Taken together, our findings suggest that even displaced revenge can achieve a sense of justice in the eyes of avengers. [ScienceDirect]

In response to a threat, the brain triggers the release of epinephrine and cortisol from your adrenal glands into the blood. As a result, your heart beats faster and stronger, your blood vessels dilate to move more blood, and your lung vessels dilate to exchange more oxygen for carbon dioxide. Equally as important, your liver breaks down glycogen (a sugar storage molecule) to glucose and dumps it into your bloodstream. All these processes work together to increase your alertness and increase the power of your muscles for a short time — like when mothers who lift cars off their small children. You are now ready to respond to the threat; however, there is an exception — you may do nothing at all. One of the major control mechanisms of the fight or flight response is the autonomic nervous system. This is part of the peripheral nervous system (PNS, outside the brain and spinal cord) and transmits information from the central nervous system to the rest of the body. The autonomic system controls involuntary movements and some of the functions of organs and organ systems. Parts of the autonomic system acts like a teeter-totter, it’s their relative balance that controls the outcomes. In the fight or flight response, the sympathetic system predominates and your heart rate increases and your blood vessels dilate. But what if the parasympathetic system gained an upper hand for a short time? […] The heart slows, the blood vessels constrict in the muscles, blood moves from muscles to the gut, and glycogen is produced from glucose. […] Many people have had the experience of parasympathetic domination coincident to a threat, for some folks it proceeds long enough to have an observable result – they faint. […] when your brain is starved of oxygen and glucose, you pass out. […] Lower animals will faint as well, but they have additional defenses along these lines. Mammals, amphibians, insects and even fish can be scared enough to fake death. […] There are overlapping mechanisms for feigned death, from tonic immobility (not moving) to thanatosis (thanat = death, and osis = condition of, playing dead). […] One study in crickets showed that those who feigned death the longest were more likely to avoid being attacked, so this is definitely a survival adaptation. [biological exceptions]

Is It Good or Bad to Zone Out, Space Out or Daydream?

A paper published recently in the journal F1000 Research rose more than a few eyebrows by claiming to support the existence of telepathy.

In the mirror we see our physical selves as we truly are, even though the image might not live up to what we want, or what we once were. But we recognize the image as “self.” In rare instances, however, this reality breaks down. […] How can the recognition of self in a mirror break down? There are at least seven main routes to dissolution or distortion of self-image: 1. psychotic disorders; 2. dementia; 3. right parietal-ish or otherwise right posterior cortical strokes and lesions; 4. the ‘strange-face in the mirror’ illusion; 5. hypnosis; 6. dissociative disorders (e.g., depersonalization, dissociative identity disorder; 7. body image issues (e.g., anorexia, body dysmorphic disorder) [The Neurocritic]

The strange-face-in-the-mirror illusion […] a never-before-described visual illusion where your own reflection in the mirror seems to become distorted and shifts identity. […] To trigger the illusion you need to stare at your own reflection in a dimly lit room. […] The participant just has to gaze at his or her reflected face within the mirror and usually “after less than a minute, the observer began to perceive the strange-face illusion.” [Mind Hacks]

We assume that we can see the world around us in sharp detail. In fact, our eyes can only process a fraction of our surroundings precisely. In a series of experiments, psychologists at Bielefeld University have been investigating how the brain fools us into believing that we see in sharp detail. The results have been published in the scientific magazine ‘Journal of Experimental Psychology: General.’ Its central finding is that our nervous system uses past visual experiences to predict how blurred objects would look in sharp detail.

People can make remarkably accurate judgments about others in a variety of situations after just a brief exposure to their behavior. Ambady and Rosenthal (1992) referred to this brief observation as a “thin slice.” For example, students could accurately predict personality traits of an instructor after watching a 30-s video clip […] a 2-s look at a picture of a face was enough to accurately determine a violent or nonviolent past. Other research has demonstrated the predictive accuracy of short observations regarding social status, psychopathy, and socioeconomic status. […] The data indicate that this ability to predict outcomes from brief observations is more intuitive than deliberatively cognitive, leading scholars to believe that the ability to accurately predict is “hard-wired and occur[s] relatively automatically.” […] The viability of using brief observations of behavior (thin slicing) to identify infidelity in romantic relationships was examined. […] In Study 1, raters were able to accurately identify people who were cheating on their romantic dating partner after viewing a short 3- to 4-min video of the couple interacting.

Here, a group of nine chefs and three scientists is pushing the boundaries in the most minimalist, nuanced way, part of an effort to ensure that this ultimate “slow food” remains relevant in a fast-paced world. The chefs are tinkering with a way of cooking that has remained unchanged for centuries. First, […] the chefs played around with the temperature at which they steamed abalone. Received wisdom says it should be steamed at 212 degrees Fahrenheit, or the boiling point of water, for two hours. […] So they spent six months — yes, six months — steaming abalone, changing the temperature in tiny increments. “It turned out that even two degrees had a huge impact on its deliciousness,” Fushiki said in his university office. The perfect temperature to steam an abalone, they concluded, is between 140 and 148 degrees, depending on how it is used. […] The second six-month period was devoted to coagulation. Not content with coagulating food, they experimented with coagulating air. “How can we make the smell of air?” Fushiki recalled the chefs asking. “Let’s whisk and make bubbles, so that each bubble contains the air, and the smell spreads when the bubbles pop.” [Washington Post]

Have you ever felt lost and alone? If so, this experience probably involved your hippocampus, a seahorse-shaped structure in the middle of the brain. About 40 years ago, scientists with electrodes discovered that some neurons in the hippocampus fire each time an animal passes through a particular location in its environment. These neurons, called place cells, are thought to function as a cognitive map that enables navigation and spatial memory. Place cells are typically studied by recording from the hippocampus of a rodent navigating through a laboratory maze. But in the real world, rats can cover a lot of ground. For example, many rats leave their filthy sewer bunkers every night to enter the cozy bedrooms of innocent sleeping children. In a recent paper, esteemed neuroscientist Dr. Dylan Rich and colleagues investigated how place cells encode very large spaces. Specifically, they asked: how are new place cells recruited to the network as a rat explores a truly giant maze? [Sick papes]

Studies of human conversation have documented that 30–40% of everyday speech is used to relay information to others about one’s private experiences or personal relationships, and recent surveys of Internet use indicate that upwards of 80% of posts to social media sites (such as Twitter) consist simply of announcements about one’s own immediate experiences. Although other primates do not generally attempt to communicate to others what they know—for example, by pointing out interesting things or modeling behaviors for others to imitate—by 9 mo of age, human children begin trying to draw others’ attention to aspects of the environment that they find important, and adults in all societies make consistent attempts to impart their knowledge to others. […] What drives this propensity for disclosure? Here, we test recent theories that individuals place high subjective value on opportunities to communicate their thoughts and feelings to others and that doing so engages neural and cognitive mechanisms associated with reward. Five studies provided sup- port for this hypothesis. Self-disclosure was strongly associated with increased activation in brain regions that form the mesolimbic dopamine system, including the nucleus accumbens and ventral tegmental area. Moreover, individuals were willing to forgo money to disclose about the self. [PNAS | PDF]

Self-disclosure plays a central role in the development and maintenance of relationships. One way that researchers have explored these processes is by studying the links between self-disclosure and liking. […] Significant disclosure-liking relations were found for each effect: (a) People who engage in intimate disclosures tend to be liked more than people who disclose at lower levels, (b) people disclose more to those whom they initially like, and (c) people like others as a result of having disclosed to them.

Divorces occur more frequently in the fourth year of marriage than at any other time. [Psychology of Romantic Relationships | PDF]

Reading ‘Fifty Shades’ linked to unhealthy behaviors

Fifty-eight adolescent girls and 60 young adult women viewed a Facebook profile with either a sexualized profile photo or a nonsexualized profile photo and then evaluated the profile owner. Results indicated that the sexualized profile owner was considered less physically attractive, less socially attractive, and less competent to complete tasks. [APA/PsycNET]

On Facebook, people frequently express emotions, which are later seen by their friends via Facebook’s “News Feed” product. Because people’s friends frequently produce much more content than one person can view, the News Feed filters posts, stories, and activities undertaken by friends. News Feed is the primary manner by which people see content that friends share. Which content is shown or omitted in the News Feed is determined via a ranking algorithm that Facebook continually develops and tests in the interest of showing viewers the content they will find most relevant and engaging. One such test is reported in this study: A test of whether posts with emotional content are more engaging. […] For people who had positive content reduced in their News Feed, a larger percentage of words in people’s status updates were negative and a smaller percentage were positive. When negativity was reduced, the opposite pattern occurred. These results suggest that the emotions expressed by friends, via online social networks, influence our own moods, constituting, to our knowledge, the first experimental evidence for massive-scale emotional contagion via social networks, and providing support for previously contested claims that emotions spread via contagion through a network.

In two longitudinal studies, university students, their roommates, and parents assessed the quality and forecast the longevity of the students’ dating relationships. […] Students assessed their relationships more positively, focusing primarily on the strengths of their relationships, and made more optimistic predictions than did parents and roommates. Although students were more confident in their predictions, their explicit forecasts tended to be less accurate than those of the two observer groups. Students, however, possessed information that could have yielded more accurate forecasts. [SAGE]

The systematic biases seen in people’s probability judgments are typically taken as evidence that people do not use the rules of probability theory when reasoning about probability but instead use heuristics, which sometimes yield reasonable judgments and sometimes yield systematic biases. This view has had a major impact in economics, law, medicine, and other fields; indeed, the idea that people cannot reason with probabilities has become a truism. We present a simple alternative to this view, where people reason about probability according to probability theory but are subject to random variation or noise in the reasoning process. […] Results suggest that people’s probability judgments embody the rules of probability theory and that biases in those judgments are due to the effects of random noise. [APA/PsycNET]

Although many studies have reported that women’s preferences for masculine physical characteristics in men change systematically during the menstrual cycle, the hormonal mechanisms underpinning these changes are currently poorly understood. Previous studies investigating the relationships between measured hormone levels and women’s masculinity preferences tested only judgments of men’s facial attractiveness. Results of these studies suggested that preferences for masculine characteristics in men’s faces were related to either women’s estradiol or testosterone levels. To investigate the hormonal correlates of within-woman variation in masculinity preferences further, here we measured 62 women’s salivary estradiol, progesterone, and testosterone levels and their preferences for masculine characteristics in men’s voices in five weekly test sessions. Multilevel modeling of these data showed that changes in salivary estradiol were the best predictor of changes in women’s preferences for vocal masculinity. These results complement other recent research implicating estradiol in women’s mate preferences, attention to courtship signals, sexual motivation, and sexual strategies, and are the first to link women’s voice preferences directly to measured hormone levels.

Representing Sex in the Brain, One Module at a Time

Why do fingers get wrinkly in the water? […] A hypothesis has been proposed which suggests that the wrinkling might be an evolutionary adaptation to make the handling of objects underwater easier. Wrinkling creates a kind of drainage path for water and so enhances the grip on an object (this is called a ‘rain tread’ hypothesis). In order to test if this hypothesis is true Kareklas et al. have recruited volunteers and tested their ability to transfer wet objects when the fingers are wrinkled and not. […] 20 participants had to transfer glass marbles from one container to another in two different conditions (1) take the marble from a container with water pass it through a small hole and put into an empty container and (2) take the marble from a container without water pass it through a small hole and put into an empty container. […] When the marble ball was dry there was no difference between the transfer time with wrinkly and smooth fingers. However, when the marble was wet then on average it took 12% less time to transfer the object with wrinkly fingers. Therefore, the study concluded that the wrinkling of fingers improves the handling of wet objects (which supports the rain tread hypothesis). Why are our fingers not always wrinkled then? In paper’s discussion Kareklas et al. suggest that there potentially are some fitness trade-offs to the wrinkly fingers. Maybe wrinkled fingers are less sensitive to pain, pressure, heat etc. and are therefore damaged easier, which would explain why it is not good to always have those wrinkles. [The Question Gene]

The work done in this room lies at the heart of a department that handles some of the UK’s most cutting-edge research on forensics and anatomy. […] The hand is Meadows’ area of focus. Variations in scars, skin pigmentation, the smallest nooks and crannies of the fingernail and, most importantly, superficial vein patterns: all of these can build a body of evidence and allow the police to identify an offender in an incriminating photograph. “The back of the hand is part of the anatomy that an offender is quite happy to have in an image, whereas they wouldn’t necessarily want their face captured,” Meadows says. In 2009, Cahid’s work was instrumental in the Neil Strachan case, part of Scotland’s biggest paedophile ring. His unusually distorted lunula (the white half moon at the bottom of a nail) helped identify and convict him. Meadows and her colleagues have built up the UK’s only database of the hand’s vein patterns, with around 800 samples. Of the 40 or so cases they have worked on, their data have resulted in over 80 per cent of suspects changing their plea. [FT]

[They] analyzed a database of 6,500 restaurant menus describing 650,000 dishes from across the U.S. Among their findings: fancy restaurants, not surprisingly, use fancier—and longer—words than cheaper restaurants do (think accompaniments and decaffeinated coffee, not sides and decaf). Jurafsky writes that “every increase of one letter in the average length of words describing a dish is associated with an increase of 69 cents in the price of that dish.” [...] Cheaper establishments also use terms like ripe and fresh, which Jurafsky calls “status anxiety” words. Thomas Keller’s Per Se, after all, would never use fresh—that much is taken for granted—but Subway would. [The Atlantic]
