POPSQuantum Theory May Explain Wishful Thinking The intriguing title hides an interesting application of mathematical tools used in quantum mechanics to model decision making under condition of uncertainty. Pothos and Busemeyer hope that further research on quantum probability models of human cognition could help answer fundamental questions about the nature of how we think. For example, what does it mean to be rational? Another example is Schrodinger’s equation, which predicts a periodic oscillation between choices after a minimum length of time. This oscillation matches with electroencephalography signals and may explain why the longer you debate on a decision, the more you fluctuate. Overall, if our brains use quantum principles, and quantum computation is known to be fundamentally faster than classical computation in computers, then perhaps quantum principles can even help explain the success of human cognition.

POPSTrust Your Gut: Too Much Thinking Leads To Bad Choices In the first study, participants rated Chinese ideograms for attractiveness. In a following study, participants were asked to judge paintings that were widely considered high- or low-quality. Subsequent groups of participants rated jellybeans and apartments. In all the studies, some participants were encouraged to deliberate and others to go with their gut. The more complex the decision, the less useful deliberation became. For example, when participants rated apartments on just three primary characteristics (location, price, and size) deliberation proved useful. But when the decision became more complex (with nine characteristics) the participants who deliberated made worse decisions.

POPS'Warrior Gene' Predicts Aggressive Behavior After Provocation The PNAS paper is the first experimental test of whether MAOA-L individuals display higher levels of actual behavioral aggression in response to provocation. A total of 78 subjects took part in the experiment over networked computers (all were male students from the University of California–Santa Barbara). The results support previous research suggesting that MAOA influences aggressive behavior, with potentially important implications for interpersonal aggression, violence, political decision-making, and crime. The finding of genetic influences on aggression and punishment behavior also questions the recently proposed idea that humans are “altruistic” punishers, who willingly punish free-riders for the good of the group.

POPSGame Theory Explains Why You Can’t Hurry Love It shows that extended courtship can take place, with a good male being willing to court for longer than a bad male and the female delaying mating. In this way the duration of a male’s courtship effort carries information about his type. By delaying mating, the female is able to make some use of this information to achieve a degree of screening. Because bad males have a greater tendency to quit the courtship game early, as time goes on and the male has not quit it becomes increasingly probable that he is a “good” male.

POPS'It takes 2 to know 1': Shared experiences change self-recognition The findings imply that shared experiences may influence the way we perceive ourselves and possibly the way we interact with others. Dr Tsakiris explains, "If I feel that you are more like me, I might then behave to you in a different way. We now test whether shared experiences can make us stereotype others less, or change our attitudes towards people of different social groups, race or gender."

POPSHow bad is giving it up for good?
Considering its duration and tenacity, some have suggested that such a belief structure must be an essential part of the human condition or psyche. Others have even suggested that perhaps there is some kind of ‘god gene’ operating or ‘spiritual’ aspect of DNA that makes us adhere to these convictions. Whatever the reason though, it’s also generally supposed that the majority of human beings will continue to maintain their faith in a higher power either ruling over their lives or, at least, being responsible for original creation. In particular, how much of humanity can humans retain once they begin melding with machines? Or the other way around, when the very nature of prosthetics, synthetic organs and implants determine how much in us is actually organic and what parts non-natural? When the contents of consciousnesses can be downloaded to memory devices or uploaded from them into brains, it’s going to be difficult to preserve the same self-image of our human wholeness.

POPSWhen giving gifts, the price is wrong In three different investigations of gift exchanges among adults, the researchers consistently found that givers wrongly assumed that money spent on gifts buys recipients’ appreciation. “I suspect we’d see different results if we studied gift appreciation among children,” Flynn predicts. Kids, more than adults, focus primarily on the nature of a gift rather than its source. Gift givers reported that relatively expensive purchases best conveyed their thoughtfulness and consideration, the Stanford researchers say. Givers apparently spent more on gifts to impress recipients with the givers’ caring, not their cash, the researchers suggest. Yet recipients preferred gifts that they really needed or that had special personal meaning, regardless of price.

POPSIrony on decline ? An interesting read. I believe that irony is a fair measure of an healthy and active intelligence. A steady decline in irony may carry consequences as serious as global warming. It might mean we become rigid thinkers imprisoned within our own conceptions and less inclined towards this highly intelligent mix of critical thinking and humor.

POPSToo much commitment may be unhealthy for relationships It also factors into one or more partners developing manic, obsessive (or needy) behaviors with regard to love. RCSE might place one at risk for serious mood changes after break-ups, divorce or threats to one's relationship. Identifying it during the early stages of a relationship can prevent such negative outcomes or help partners recognize that they are incompatible.

POPSTaking A Shower Improves Moral Judgment The research was conducted through two experiments with university students. In the first, they were asked to complete a scrambled sentence task involving 40 sets of four words each. By underlining any three words, a sentence could be formed. For the neutral condition, the task contained 40 sets of neutral words, but for the cleanliness condition, half of the sets contained words such as ‘pure, washed, clean, immaculate, and pristine’. The participants were then asked to rate a series of moral dilemmas including keeping money found inside a wallet, putting false information on a resume and killing a terminally ill plane crash survivor in order to avoid starvation. The second experiment saw the students watch a ‘disgusting’ film clip before rating the same moral dilemmas. However, half the group were asked to first wash their hands.

POPSDead Famous: 18th Century Obituaries Sparked Modern Cult Of Celebrity The Gentleman’s Magazine in 1789 gave an account of the life of Isaac Tarrat, a man known to hire himself out to impersonate a doctor and tell fortunes in a fur cap, a large white beard and a worn damask night gown. Another subject, Peter Marsh of Dublin, was made famous by his convictions about his own death in 1740. After being hit by a mad horse which died soon after, Mr Marsh convinced himself that he would also go mad and die. The Gentleman’s Magazine reported that he duly died “of a conceit that he was mad”. Fascinating !!!

POPSSocial Interactions Can Alter Gene Expression In Brain, And Vice Versa A critical insight came in 1992, in a study of songbirds led by David Clayton. He and his colleagues found that expression of a specific gene increases in the forebrain of a zebra finch or canary just after it hears a new song from a male of the same species. This gene, egr1, codes for a protein that itself regulates the expression of other genes.

POPSThe Relationship Between the Media and Society The result is a society dotted with a few people that feel they are capable and worthy and large numbers of people who feel that they do not measure up, believing themselves to be too much or too little of one thing or another; too fat, too thin; too short, too tall; not smart enough or not pretty enough; too different from what is considered acceptable. In the process, worthwhile individuals with much to offer, people who may hold ideas and suggestions for improving the world for all, become silenced, and society becomes the ultimate loser. For many years, the media has been telling people what is socially acceptable, what is valuable, encouraging some and limiting others; perhaps it's time the people begin telling the media that more positive, life-affirming messages are warranted.

POPSAttention and Emotional Self Regulation 1) Alerting: helps us maintain an Alert State. 2) Orienting: focuses our senses on the information we want. For example, you are now listening to my voice. 3) Executive Attention: regulates a variety of networks, such as emotional responses and sensory information. This is critical for most other skills, and clearly correlated with academic performance. It is distributed in frontal lobes and the cingulate gyrus. The development of executive attention can be easily observed both by questionnaire and cognitive tasks after about age 3–4, when parents can identify the ability of their children to regulate their emotions and control their behavior in accord with social demands. Very interesting read.

POPSGossip more powerful than truth The researchers then took the game a step further and showed the students the actual decisions people had made. But they also supplied false gossip that contradicted that evidence. In these cases, the students based their decisions to award money on the gossip, rather than the hard evidence, showing such information is a powerful tool, Sommerfeld said. "Rationally if you know what the people did, you should care, but they still listened to what others said," he said. "They even reacted on it if they knew better." Researchers have long used similar games to study how people cooperate and the impact of gossip in groups. Scientists define gossip as social information spread about a person who is not present, Sommerfeld said. In evolutionary terms, gossip can be an important tool for people to acquire information about others' reputations or navigate through social networks at work and in their everyday lives, the study said. One example could be using gossip to learn tha

POPSUnderstanding the nervous system by walking in a neuron's shoes “The problem is that the relationship between inputs and outputs is very complicated, even for a single neuron,” Fiorillo told PhysOrg.com. “By contrast, I have tried to figure out what a neuron knows about the world. This is possible because we already know a great deal about the biophysical properties of neurons. I think that if we can figure out what information a neuron has, then we will be able to make better sense of its inputs and outputs. I think that this approach to information will prove to be very useful, regardless of the success of the rest of the theory.” Interesting to read.

POPSFear Factor: How Herd Mentality Drives Us "Whether it's the fear of being the odd person out, whether it's the fear of uncertainty or the fear of losing your shirt in the market, the fear starts to compel you to do something, because a million years ago, that fear meant you probably had to run or fight," Berns said. But reactions that saved our ancestors from saber-toothed tigers don't make as much sense on the floor of the Stock Exchange. Financial historian Jeff Madrick says that's how we got into trouble in the first place - by developing the notion that the stock is highly rational. "That encouraged this herd behavior," he said. "People would say, 'The stock market is right. Let's get in here.' That was the mythology that fed the herd behavior." So the group think that helped build the bubble is now leading the charge to pop it. "I think there's probably a panic now," Madrick said. Berns agreed: "You could call it panic; I would." But the Bronx Zoo's Pat Thomas says, "It's definitely a survival mechanism."

POPSThe Power of a Handshake: How Touch Sustains Personal and Business Relationships Recent research from Zak's neuroeconomics lab has shown that the human brain uses oxytocin to unconsciously assess if a person is trustworthy using our memory of past encounters and all of our senses, including touch. If the stranger is a good match for other trustworthy people, the brain releases oxytocin, telling us it is safe to trust. Interesting read.
