"The influence of the colour red in sports: Judges were shown a video of a Tae Kwon Do match and awarded more points to the red competitor (versus the blue competitor). When the colours were digitally reversed, judges awarded more points to the other, now red, competitor. Edit: Since there's a lot more interest than I expected, here's some more info: Red may be a signal of dominance as reddened skin is associated with higher testosterone (or possibly higher fertility in women). Wearing red may induce intrinsic psychological effects which increase dominance in addition to altering the perception of others. Researchers found that putting red leg bands on birds increased dominant behaviour, as they took the "lion's share" of the food. For my psychology degree dissertation, I presented photos of men to be rated on a scale of Friendly (0) to Threatening (10). Men received a higher threat score if I photoshopped their t-shirt to be red :). Edit 2: Thank you for the gold award :). "

There's been a couple interesting studies on mice/rat Utopias and overcrowding. I think the one I linked actually inspired the rats of NIMH book.
Recent small sample size experiment in toddlers (18mo, I think) investigating the link between fine + gross motor skills and time spent on a computer tablet. Results showed no difference in gross motor skills between children who had spent lots of time on a tablet, and children who had spent no time at all on one. Fine motors skills, and understanding the task was largely increased in those who had spent time on tablets.
I am fascinated by the psychology of the placebo effect. ELI5 for clarity, a person is given a benign substance with no known health benefits but are told that it will treat/cure/etc their condition, and it does. While this is often observed in drug tests where half of the test subjects receive a new drug, and half receive a sugar pill there has been some research that Dr. Andrew Weil cites that shows the placebo effect can be capitalized on and used to help people heal. Essentially your brain can do what many drugs do if you believe that it can.
Not just one experiment, but a whole thesis and series of works supporting it: According to the Just world Fallacy we expect good or bad things to happen to people for a reason and go to pretty interesting length to make up for the lack of justice. Like someone winning the lottery and us thinking they deserve it.
There is an optical variable called tau, expressed as image size divided by image expansion rate, and it has been shown to be used to perceive time to contact of an approaching object. Even diving birds have been shown to use it. The most interesting part is that the tau quantity is perceived as a whole, directly, and not arrived at by any sort of implicit calculations. Also, it's time derivative, called tau-dot, is used to control deceleration toward an object, e.g. braking in a car. Physical activity, in the form of aerobic activity, does a better job of maintaining cognitive ability in aging than any brain training game or cognitively stimulating activities. Casual video games can reduce stress. (Like candy crush, sushi cat) Exposure to nature reduces stress and improves cognitive ability.
"The Pratfall Effect. In essence, if you are considered "highly competent," you become more likable after a small mistake. The classic example (and what happened in the initial experiment) involved people spilling coffee during an interview to be a contestant on a show. If someone demonstrated themselves to be intelligent and competent, they became more likeable after spilling coffee on themselves. Anyone previously seen as average or less-than-ideal actually suffered from the blunder. "
A lot of good material for that regard in Thinking, Fast and Slow
"Derren Brown - The Push It is a show, and not an exact science but Brown is an illusionist and mentalist. He likes to find out how people tick, in his show "The Push" he selects a few people that easily conform to group stuff etc through a lengthy selection process, then invite them to a BS get together / charity auction with everyone else being actors. This individual is then pushed to the limits to see what it would take to get them to kill another human being (pushing them off the top of a building). It's an amazing watch and on Netflix. I think 3/5 "kill" the old guy "
"Hedonic Adaptation. Put simply, a person who had just won the lottery and another person who had just been paralysed took a survey to measure their life contentment. Obviously it was high and low, respectively. However, they both took the same survey a year later and both scored similarly. The point being that regardless what happens to you in life, good or bad, you will always adapt and spend most of your life feeling "neutral." "
