Strangers smile less to one another when they have their smartphones, study finds

PsyPost reports: New research suggests that phones are altering fundamental aspects of social life. According to a study published in Computers in Human Behavior, strangers smile less to one another when they have their smartphones with them. “Smartphones provide easy access to so much fun and useful content, but we wondered if they may have subtle unanticipated costs for our social behavior in the nondigital world. Smiling is a fundamental human social behavior that serves as a signal of people’s…

How Donald Trump appeals to men secretly insecure about their manhood

How Donald Trump appeals to men secretly insecure about their manhood

Eric Knowles and Sarah DiMuccio write: From boasting about the size of his penis on national television to releasing records of his high testosterone levels, President Trump’s rhetoric and behavior exude machismo. His behavior also seems to have struck a chord with some male voters. See, for example, the “Donald Trump: Finally Someone With Balls” T-shirts common at Trump rallies. But our research suggests that Trump is not necessarily attracting male supporters who are as confidently masculine as the president…

By only working in their own backyards, what do psychology researchers miss about human behavior? Arthimedes/Shutterstock.com By Daniel Hruschka, Arizona State University Over the last century, behavioral researchers have revealed the biases and prejudices that shape how people see the world and the carrots and sticks that influence our daily actions. Their discoveries have filled psychology textbooks and inspired generations of students. They’ve also informed how businesses manage their employees, how educators develop new curricula and how political campaigns persuade…

How reliable are the memories of sexual assault victims?

How reliable are the memories of sexual assault victims?

Comments 0 Comment

Jim Hopper writes: Incomplete memories of sexual assault, including those with huge gaps, are understandable–if we learn the basics of how memory works and we genuinely listen to survivors. Such memories should be expected. They are similar to the memories of soldiers and police officers for things they’ve experienced in the line of fire. And a great deal of scientific research on memory explains why. I’m an expert on psychological trauma, including sexual assault and traumatic memories. I’ve spent more…

Octopuses on ecstasy reveal genetic link to evolution of social behaviors in humans

Johns Hopkins University School of Medicine: By studying the genome of a kind of octopus not known for its friendliness toward its peers, then testing its behavioral reaction to a popular mood-altering drug called MDMA or “ecstasy,” scientists say they have found preliminary evidence of an evolutionary link between the social behaviors of the sea creature and humans, species separated by 500 million years on the evolutionary tree. A summary of the experiments is published Sept. 20 in Current Biology,…

Kaidi Wu and David Dunning write: In 1806, entrepreneur Frederic Tudor sailed to the island of Martinique with a precious cargo. He had harvested ice from frozen Massachusetts rivers and expected to make a tidy profit selling it to tropical customers. There was only one problem: the islanders had never seen ice. They had never experienced a cold drink, never tasted a pint of ice cream. Refrigeration was not a celebrated innovation, but an unknown concept. In their eyes, there…

Nabeelah Jaffer writes: A few years ago I discovered that my friend Tom was a white supremacist. This put me in a strange position: I am a Muslim and the daughter of immigrants. I am a member of one of the so-called invading groups that Tom fears and resents. He broadcasts his views from his social media accounts, which are a catalogue of aggrieved far-Right anger. One post warns ‘the Muslim invaders to keep their filthy hands off our women’….

Natalie Wolchover writes: In his 1890 opus, The Principles of Psychology, William James invoked Romeo and Juliet to illustrate what makes conscious beings so different from the particles that make them up. “Romeo wants Juliet as the filings want the magnet; and if no obstacles intervene he moves towards her by as straight a line as they,” James wrote. “But Romeo and Juliet, if a wall be built between them, do not remain idiotically pressing their faces against its opposite…

The Stanford Prison Experiment was massively influential. We just learned it was a fraud

Brian Resnick writes: The Stanford Prison Experiment, one of the most famous and compelling psychological studies of all time, told us a tantalizingly simple story about human nature. The study took paid participants and assigned them to be “inmates” or “guards” in a mock prison at Stanford University. Soon after the experiment began, the “guards” began mistreating the “prisoners,” implying evil is brought out by circumstance. The authors, in their conclusions, suggested innocent people, thrown into a situation where they…

The spiritual part of our brains — religion not required

Ephrat Livni writes: Scientists seek to quantify everything—even the ineffable. And so the human search for meaning recently took a physical turn as Columbia and Yale University researchers isolated the place in our brains that processes spiritual experiences. In a new study, published in Cerebral Cortex (paywall) on May 29, neuroscientists explain how they generated “personally relevant” spiritual experiences in a diverse group of subjects and scanned their brains while these experiences were happening. The results indicate that there is…

Nick Chater writes: At the climax of Anna Karenina, the heroine throws herself under a train as it moves out of a station on the edge of Moscow. But did she really want to die? Had the ennui of Russian aristocratic life and the fear of losing her lover, Vronsky, become so intolerable that death seemed the only escape? Or was her final act mere capriciousness, a theatrical gesture of despair, not seriously imagined even moments before the opportunity arose?…

Okay, we get it, you’re happy – no need to rub it in. Very_Very/Shutterstock.com By Marie Helweg-Larsen, Dickinson College The new World Happiness Report again ranks Denmark among the top three happiest of 155 countries surveyed – a distinction that the country has earned for seven consecutive years. The U.S., on the other hand, ranked 18th in this year’s World Happiness Report, a four-spot drop from last year’s report. Denmark’s place among the world’s happiest countries is consistent with many…

Last August, John Lanchester wrote: [Mark Zuckerberg] is very well aware of how people’s minds work and in particular of the social dynamics of popularity and status. The initial launch of Facebook was limited to people with a Harvard email address; the intention was to make access to the site seem exclusive and aspirational. (And also to control site traffic so that the servers never went down. Psychology and computer science, hand in hand.) Then it was extended to other…

The Verge reports: One-year-old babies may not be able to speak, but they are able to think logically, according to new research that shows the earliest known foundation of our ability to reason. Legendary psychologist Jean Piaget believed that we didn’t have logical reasoning abilities until we were seven, but scientists scanned the eyes of 48 babies and found that they’re able to reason through the process of elimination. The research was published today in the journal Science. The type…

By the admission of Facebook’s own VP of advertising, Rob Goldman, Russia’s goal of sowing division in America has been served “incredibly well” through its use of Facebook: The main goal of the Russian propaganda and misinformation effort is to divide America by using our institutions, like free speech and social media, against us. It has stoked fear and hatred amongst Americans. It is working incredibly well. We are quite divided as a nation. — Rob Goldman (@robjective) February 17,…
