Many psychological experiments have been valid and ethical, allowing researchers to make new treatments and therapies available, and giving other insights into our motivations and actions. Sadly, others have ended up backfiring horribly — ruining lives and shaming the profession. Here are ten psychological experiments that spiraled out of control. 10. Prisoners and guards In 1971, social psychologist Philip Zimbardo set out to interrogate the ways in which people conform to social roles, using a group of male college students to take part in a two-week-long experiment in which they would live as prisoners and guards in a mock prison. 9.

Survival Bow Making Instructions By Jason Knight The following bow making instructions will help you construct an effective bow in a relatively short amount of time. A quickie bow is a fast-made bow for immediate use in a survival situation. The reason it is called a “quickie” bow is because it is made at the time the wood is harvested, rather than waiting a year or more for the wood to season (as is typical for regular bow construction). Survival Bow Making Instructions 1. The first step is to select the proper materials. For a quickie bow, you want to start with a relatively straight section of sapling or branch that is free of knots, side branches, and twists. 2. Stand the bow stave upright on the ground, hold the top loosely with one hand, and push outward lightly on the middle of the bow. Now find the middle point of the stave and mark out your handhold area by measuring and marking 3 inches out from the center in both directions. 3. Take off material slowly and re-check the bend of the limbs frequently. 4. 5. 6.

Psychologists also studied more benign, pleasant, and productive social activities of humans, after the post-war decades. The rise of cognitive psychology in the 1970s and beyond ushered in a new era of social cognitive psychology, focusing on the informationg processing carried out by people to evaluate each other and group situations. How this chapter is organized More than most disciplines, social psychology is marked by classic experiments. The opening portion of the chapter highlights research on group influences upon the individual. Related topics in other chapters Write to Dr.
Freedom Vaults : Guidelines for Saying No to Police Searches One of the main powers that law enforcement officers carry is the power to intimidate citizens into voluntarily giving up their rights. Police are trained to believe in their authority and trained to perform their interactions with private citizens with confidence. It is their job to deal with problems and they learn to manage uncomfortable situations through strength. Most people, when confronted by police get a mild panic reaction, become anxious, and try to do whatever they can to minimize the time spent with the officer. A common situation is that of the traffic stop. The Federal Supreme Court has ruled that as long as the police do not force an individual to do something, the individual is acting voluntarily, even if a normal person would feel very intimidated and would not reasonably feel they could say no. Unfortunately police will often try to push citizens to accept a search, to the point of ignoring when you say "no". The Terry v. In a recent decision (Wyoming v. Stay Calm.
Klimt University of Vienna Ceiling Paintings The Klimt University of Vienna Ceiling Paintings, also known as the Faculty Paintings, were a series of paintings made by Gustav Klimt for the ceiling of the University of Vienna's Great Hall between the years of 1900-1907. In 1894, Klimt was commissioned to paint the ceiling. Upon presenting his paintings, Philosophy, Medicine and Jurisprudence, Klimt came under attack for 'pornography' and 'perverted excess' in the paintings. Philosophy[edit] Philosophy, 1899–1907. Philosophy was the first of the three pictures presented to the Austrian Government at the seventh Vienna Secession exhibition in March 1900. Medicine[edit] Medicine, 1899–1907 Medicine was the second painting, presented in March 1901 at the tenth Secession Exhibition. Jurisprudence[edit] Jurisprudence, 1899–1907 Jurisprudence, too, is laden with anxiety: A condemned man is depicted surrounded by three female furies and a sea monster, while in the background, the three goddesses of Truth, Justice and Law look on.

List of cognitive biases Cognitive biases are tendencies to think in certain ways that can lead to systematic deviations from a standard of rationality or good judgment, and are often studied in psychology and behavioral economics. There are also controversies over some of these biases as to whether they count as useless or irrational, or whether they result in useful attitudes or behavior. For example, when getting to know others, people tend to ask leading questions which seem biased towards confirming their assumptions about the person. However, this kind of confirmation bias has also been argued to be an example of social skill: a way to establish a connection with the other person.[7] Although this research overwhelmingly involves human subjects, some findings that demonstrate bias have been found in non-human animals as well. Decision-making, belief, and behavioral biases[edit] Many of these biases affect belief formation, business and economic decisions, and human behavior in general. Social biases[edit]
The story of the Gömböc September 2009 Play this movie to see the Gömböc wriggle. This article is also available as a podcast. A Gömböc is a strange thing. It looks like an egg with sharp edges, and when you put it down it starts wriggling and rolling around with an apparent will of its own. Balancing act The defining feature of a Gömböc is the fact that it's got just two points of equilibrium: one is stable and the other is unstable. A Gömböc made from plexiglass. "It's a bit like putting a ball on a hilly landscape," says Domokos, "if you put the ball down at a generic point, it will always roll off in the same direction, down into the valley. To give it its full mathematical description, a Gömböc is a three-dimensional, convex and homogeneous object with exactly one stable point of equilibrium and one unstable point of equilibrium. Doubtful existence An ellipse has two stable and two unstable points of equilibrium. A geometric stem cell "This is intuitively clear," says Domokos. Mathematical field work
How to Trick Your Brain for Happiness This month, we feature videos of a Greater Good presentation by Rick Hanson, the best-selling author and trailblazing psychologist. In this excerpt from his talk, Dr. Hanson explains how we can take advantage of the brain’s natural “plasticity”—it’s ability to change shape over time. gobyg There’s this great line by Ani Tenzin Palmo, an English woman who spent 12 years in a cave in Tibet: “We do not know what a thought is, yet we’re thinking them all the time.” It’s true. In recent years, though, we have started to better understand the neural bases of states like happiness, gratitude, resilience, love, compassion, and so forth. Ultimately, what this can mean is that with proper practice, we can increasingly trick our neural machinery to cultivate positive states of mind. But in order to understand how, you need to understand three important facts about the brain. Fact one: As the brain changes, the mind changes, for better or worse. Fact two: As the mind changes, the brain changes. 1. 2. 3.
Relativistic Baseball What would happen if you tried to hit a baseball pitched at 90% the speed of light? - Ellen McManis Let’s set aside the question of how we got the baseball moving that fast. We'll suppose it's a normal pitch, except in the instant the pitcher releases the ball, it magically accelerates to 0.9c. From that point onward, everything proceeds according to normal physics The answer turns out to be “a lot of things”, and they all happen very quickly, and it doesn’t end well for the batter (or the pitcher). The ball is going so fast that everything else is practically stationary. The ideas of aerodynamics don’t apply here. These gamma rays and debris expand outward in a bubble centered on the pitcher’s mound. The constant fusion at the front of the ball pushes back on it, slowing it down, as if the ball were a rocket flying tail-first while firing its engines. After about 70 nanoseconds the ball arrives at home plate. Suppose you’re watching from a hilltop outside the city.
