Short history of iterated prisoner’s dilemma tournaments

by Artem Kaznatcheev in Evolutionary Games Group

Nineteen Eighty — if I had to pick the year that computational modeling invaded evolutionary game theory then that would be it. In March, 1980 — exactly thirty-five years ago — was when Robert Axelrod, a professor of political science at University of Michigan, published the results of his first tournament for iterated prisoner’s dilemma […]...

 The gift of feeling powerful: “I find myself so inspiring”

by Doug Keene in The Jury Room

We have written about power poses and other strategies to help yourself feel powerful.  Be clear, though—you do not become more powerful by doing such things, but it might make you feel that way, which in itself can be communicated as confidence or authority. This post isn’t about how to make yourself feel powerful, it […]

"I did it for the team" – How outsiders cheat in pursuit of popularity

by BPS Research Digest in BPS Research Digest

If you would do anything to stay popular with your team-mates, what might follow? Bending the rules? Cheating? Sabotage of rivals? An international team led by Stefan Thau of INSEAD investigated “pro-group” unethical behaviours, and they suggest the people most likely to connive to boost the team are those at its margins, fearful of exclusion.The experiment gave participants an easy opportunity to cheat at an anagram task, as the setup meant they themselves reported how many they s........

Systemic low grade inflammation and bowel issues in autism?

by Paul Whiteley in Questioning Answers

The paper from Katarina Babinská and colleagues [1] (open-access here) presents an interesting, if preliminary take on two potentially important issues linked to at least some cases of autism: gastrointestinal (GI) issues and inflammation (see here and see here respectively).Detailing the examination of plasma levels of a compound called high mobility group box 1 protein (HMGB1), a protein which has the apparent ability to 'bend DNA' and has some pretty potent immune effects [2] (one paper........

Vitamin D status affecting autoimmune disease risk?

by Paul Whiteley in Questioning Answers

I want to bring the paper from Tea Skaaby and colleagues [1] to your attention for today's brief blog post and their observation that there may be: "a possible protective role of a higher vitamin D status on autoimmune disease". Autoimmune disease by the way, reflects a breakdown in communication and tolerance of 'self' whereby the body attacks healthy tissue.Their findings, based on an analysis of "a total of 12,555 individuals from three population-based studies with measurements of vitam........

ME/CFS is real: confirmation if it is needed...

by Paul Whiteley in Questioning Answers

"Scientists discover robust evidence that chronic fatigue syndrome is a biological illness" went the title of the press release for the study by Mady Hornig and colleagues [1] (open-access) detailing an immune 'signature' and also possible staging of the illness.I couldn't help but wince at some of the media headlines reporting on this study as 'proof' that chronic fatigue syndrome / myalgic encephalomyelitis (CFS/ME) is a real illness.

Good News, Northerners: Birds from Harsher Climates Are Smarter

by Elizabeth Preston in Inkfish



You won't see a chickadee shoveling out a parking space and claiming it with a folding chair, no matter how good your binoculars are. But birds, too, have to be resourceful when they live in inhospitable climates. Travel just 600 meters up a mountain, and you'll find chickadees vastly more clever than their peers living a more comfortable life below.

How do you test the cleverness of birds? Using tubes with tasty worms inside, naturally. Biologists don't like to call animals "smart," thou... Read more »

Like thrillers? Scary movies? How do you feel about immigrants?

by Rita Handrich in The Jury Room

So here’s a strange study. Or perhaps an unexpected outcome. We enjoy a good suspenseful thriller but never knew it might be messing with our political beliefs. Wait until you see this! The researchers were curious about how various forms of physiological reactivity (aka anxiety) would affect a political belief about one particular issue: attitudes […]

What do clients think of psychotherapy that doesn't work?

by BPS Research Digest in BPS Research Digest

Psychotherapy works for most people, but there's a sizeable group for whom it's ineffective, or worse still, harmful. A new study claims to be the first to systematically investigate what the experience of therapy is like for clients who show no improvement after therapy, or who actually deteriorate.Andrzej Werbart and his colleagues conducted in-depth interviews with 20 non-improved clients (out of a larger client group of 134) who were enrolled in individual or group psychoanalytic psychothera........

Hyperprolactinemia and risperidone use in autism

by Paul Whiteley in Questioning Answers

The findings reported by Yaowaluck Hongkaew and colleagues [1] (open-access) on prolactin levels being "positively and significantly associated with risperidone dose" in cases of children and adolescents diagnosed with an autism spectrum disorder (ASD) is the point of discussion today.Prolactin by the way, is the hormone most commonly associated with stimulating breast development and milk production in women. To quote from the US National Institute of Health (NIH) entry on prolactin: "There is ........ Read more »

Some student-professor pairings lead to "unusually effective teaching" (and it's possible to predict which ones)

by BPS Research Digest in BPS Research Digest

Video trailers can be used to predict whichlecturers are the best teachers, and whichstudents they are especially suited to.In the near future, students could be presented with a series of video trailers of different professors at their university. Based on their ratings of these videos, the students will be paired with the professors who provide the best fit. The outcome will be superior learning, and greater student satisfaction.That's the promise of a new study that asked 145 psychology under........ Read more »

Examining Evidence for Leaderboards and Learning

by Richard Landers in NeoAcademic

As I described in my last post, gamification is often misused and abused, applied in ways and in situations where it is unlikely to do much good. When we deploy new learning technologies, the ultimate goal of that change should always be clear, first and foremost. So how do you actually go about setting that sort of […]The post Examining Evidence for Leaderboards and Learning appeared first on NeoAcademic.Related articles from NeoAcademic:Psychological Theory and Gamification of Learning........

Why You Need to Socialize Your Puppy

by CAPB in Companion Animal Psychology Blog

The importance of socialization can’t be stressed enough.These days, more and more people understand that puppies need to be socialized. But sometimes people wonder, how do we know this? It’s based on classic research in canine science.Many papers contribute to our understanding of puppies. In 1950, J.P. Scott and Mary-‘Vesta Marston published a study of 17 litters, including the earliest age at which they opened their eyes for the first time, began to walk, and engaged in play. They hypot........

The six forms of resistance shown by participants in Milgram's notorious "obedience studies"

by BPS Research Digest in BPS Research Digest

When discussing Milgram's notorious experiments, in which participants were instructed to give increasingly dangerous electric shocks to another person, most commentators take a black or white approach.Participants are categorised as obedient or defiant, and the headline result is taken as the surprising number of people – the majority – who obeyed by going all the way and administering the highest, lethal voltage.A new study takes a different stance by looking at the different acts of resis........
