Is men’s capacity for arousal and orgasm with real partners reduced by their habituating (desensitizing) to the variety of streaming explicit sexuality? Is compulsive pornography-viewing literally a downer? Does it contribute to erectile dysfunction (ED)? If so, this is news worth reporting by us textbook authors, and would be a practical, nonmoral reason for encouraging boys and men to limit their hours in online fantasyland.Read More
Some psychological science findings are just plain fun. Few are more so than the studies of what Brett Pelham and his colleagues call “implicit egotism”—our tendency to like what’s associated with us.Read More
When 270 researchers in an “Open Science Collaboration” network redid 100 recent studies from three leading journals, only 36 percent of the findings replicated. But now another research team, led by Harvard social psychologist Daniel Gilbert, has reanalyzed the data and arrived at a radically different conclusionRead More
How do self-important, self-focused, self-promoting narcissists fare over time? Does their self-assurance, charm, and humor make a generally favorable impression, especially in leadership roles? Or is their egotism, arrogance, and hostility off-putting?Read More
Amid concerns about the replicability of psychological science findings comes “a cause for celebration,” argue behavior geneticist Robert Plomin and colleagues (here). They identify ten “big” take-home findings that have been “robustly” replicated. Some of these are who-would-have-guessed surprises.Read More
You’ve likely heard the NPR ads for brain fitness games offered by Lumosity. “70 Million brain trainers in 182 countries challenge their brains with Lumosity,” declares its website. The hoped-for results range from enhanced cognitive powers to increased school and work performance to decreased late-life cognitive decline or dementia.
But do brain-training games really makes us smarter or enlarge our memory capacity? In our just-released Exploring Psychology, 10th Edition, Nathan DeWall and I suggest “that brain training can produce short-term gains, but mostly on the trained tasks and not for cognitive ability in general.” As an earlier TalkPsych blog essay reported, Zachary Hambrick and Randall Engle have “published studies and research reviews that question the popular idea that brain-training games enhance older adults’ intelligence and memory. Despite the claims of companies marketing brain exercises, brain training appears to produce gains only on the trained tasks (without generalizing to other tasks).”
And that is also the recently announced conclusion of the Federal Trade Commission (FTC), when fining Lumosity’s maker, Lumos Labs, $2 million for false advertising. As FTC spokesperson Michelle Rusk reported to Science, “The most that they have shown is that with enough practice you get better on these games, or on similar cognitive tasks . . . .There’s no evidence that training transfers to any real-world setting.”
Although this leaves open the possibility that certain other brain-training programs might have cognitive benefits, the settlement affirms skeptics who doubt that brain games have broad cognitive benefits.
As I make words march up the screen, I often feel more like a secretary, a mere recorder of ideas and words that come from I know not where. And yet I also know that if I keep reading and reflecting—and feeding the friendly little genie that each of us has in our heads—it will keep dictating, and I will continue transcribing.Read More
“Happiness doesn’t bring good health,” headlines a December 9 New York Times article. “Go ahead and sulk,” explain its opening sentences. “Unhappiness won’t kill you.” Should we forget all that we have read and taught about the effects of negative emotions (depression, anger, stress) on health?Read More
The shared threat of terrorism further hijacks rationality, by triggering us/them thinking, inflaming stereotypes of the “other” among us, and creating scapegoats. Thus, although refugees have reportedly committed no terrorist acts—either in Paris or, since 2001, in the USA—more than half of U.S. governors are seeking to block Syrian refugees, and reported threats against Muslims and Mosques have increased.Read More
In response to the big “Reproducibility Project” news that only 36 percent of a sample of 100 psychological science studies were successfully replicated, psychologists have reassured themselves that other fields, including medicine, also have issues with reproducibility. Moreover, differing results sometimes illuminate differing circumstances that produce an effect. Others have agreed on a lesson for textbook authors.Read More
I am just back from a fourth visit to China, where I enjoyed generous hospitality and have again spoken to colleagues and students in China’s fast growing social psychology field. My task was to speak at a Shanghai conference focusing on how the information age is transforming culture, in China as elsewhere.Read More
For my birthday, I wanted to run 100 miles as fast as I could. Luckily, I had a perfect opportunity. There was a 24 hour running race within driving distance of my house. There was a bigger purpose in my run. I could determine whether a recent test of my speed and endurance would replicate.Read More
