Each of these specialty areas has been strengthened over the years by research studies designed to prove or disprove theories and hypotheses that pique the interests of psychologists throughout the world. In 2000, an article in the It seems impossible now, but in the 1950s, psychologist Harry Harlow placed baby monkeys in isolation for a year just to prove that children need their mothers’ love. Here are 10 classic psychological studies that may change the way you understand yourself. To check cancer biology results, for instance, the Center for Open Science will have to spend far more money than was spent on psychology.Stefano Bertuzzi, the executive director of the American Society for Cell Biology, said that the effort was long overdue, given that biology has some of the same publication biases as psychology. Last year, the University of Virginia led a new The two latest examples are widely cited papers from 1988 and 1998.The latter assumption has been the basis of a huge amount of follow-on psychological studies, but now Martin Hagger from Curtin University in Australia has led researchers from 24 labs in an attempt to recreate the seminal paper, and found no evidence that the effect exists.Big news: RRR of ego depletion reveals no effect. Non-stutterers were told they actually did stutter; the children devolved into poor students and fearful speakers—one even ran away from the orphanage, according to the In a now-famous contentious 1971 experiment on imprisonment, 35 college students were enlisted to play guards and 35 others acted as prisoners in a basement at Stanford University.

That's called the scientific method, and it's how we attempt to eliminate most flukes and false positives from published research. We all have some capacity for evil. Throughout the last century, various researchers have hypothesized many theories relating to psychology. In a series of studies on the psychology of obedience to authority, Stanley Milgram documented, without question, that under certain conditions a large … "[T]his does not mean the entire facial feedback hypothesis is dead in the water," "Many diverse studies have supported the hypothesis, The results could be due to a number of other variables - like, maybe people today don't find Only more investigation will help us know for sure.But in the meantime, all this hype over the reproducibility crisis in the media lately can only be a good thing for the state of science. It did not. In other words, the insights about the mind uncovered by those experimenters That’s why many scientists are working to reproduce classic experiments — recreating their conditions and methodologies to see if they arrive at the same results — and reinvestigating the reasons why some studies led to new discoveries The new paper lays out the 28 studies one after another, comparing and contrasting the original findings with what contemporary scientists discovered. But the remaining eight labs didn't, and when the results were combined, the effect disappeared. The two latest examples are widely cited papers from 1988 and 1998. Now they are again taking the lead in improving their replication record. The CIA has been implicated in a number of illegal mind-control experiments that went horribly wrong for the subjects. MJgraphics/Shutterstock.com Two More Classic Psychology Studies Just Failed The Reproducibility Test For years now, researchers have been warning about a reproducibility crisis in science - the realisation that a lot of seminal papers, particularly in psychology, don't actually hold up when scientists take the time to try to reproduce the results. Therapists and educators rely on such findings to help guide decisions, and the fact that so many of the studies were called into question could sow doubt in the scientific underpinnings of their work.“I think we knew or suspected that the literature had problems, but to see it so clearly, on such a large scale — it’s unprecedented,” said Jelte Wicherts, an associate professor in the department of methodology and statistics at Tilburg University in the Netherlands.More than 60 of the studies did not hold up. Confirmation bias is the tendency to search for, interpret, favor, and recall information that confirms or supports one's prior beliefs or values. He collected sexual data—as well as identities, addresses, and other personal information—on his unwitting subjects at a time when homosexuality was still illegal in some states. In 1983, researchers at UCLA began studying 50 patients suffering from schizophrenia. Zip. Replication is an important part of the scientific method that helps us nut out what's really going on - it could be that the new researchers did something differently, or that the trend is more subtle than originally thought.But the problem is that, for decades now, the importance of replicating results has been largely overlooked, with researchers usually choosing to chase a 'new' discovery rather than fact-checking an old one - thanks to the That's brought us to the 'crisis' we're in now, where most papers that are published can't be replicated. These are three of the studies, and some possible explanations for why they couldn’t be replicated.The project began in 2011, when a University of Virginia psychologist decided to find out whether suspect science was a widespread problem. Nosek’s team addressed this complaint in part by requiring the researchers attempting to replicate the findings to collaborate closely with the original authors, asking for guidance on design, methodology and materials.

John Ioannidis, a director of Stanford University’s Meta-Research Innovation Center, who once estimated that about half of published results across medicine were inflated or wrong, noted the proportion in psychology was even larger than he had thought. The infant rhesus monkeys suffered various tortures in isolated confinement, and they went on to develop severe psychosis and depression.
