Exercise Can Help Ease Depression

An exercise group’s depression was reduced while studying symptoms of depression. It started to work after three weeks, and at the program end.

During this time, the control group’s depression symptoms remained unchanged.

The Police Believe a lot of Psychology Myths Related to Their Work

What more, police officers have more confidence than the public in their false beliefs.

There are the statements or myths:

“People only confess when they have actually committed the crime they are being charged with.”

“Eye-witnesses are always the most reliable source of case-related information.”

All of these statements are not supported by research.

UK police believed, on average, in 18 of the 50 false statements vs. 19 among the public.

Even in interview techniques the police performed as poorly as the public, despite the training.

Red increases attractiveness. Really?

There are three research studies which didn’t confirm it.

In this study, the men gave smaller tips to female servers who wore red.

In the second research, 206 young Dutch men judged the attractiveness of a woman on a dating site. The women wore either a red, black or white shirt. Some men wanted to find a one-night stand, the others a long-term partner. Regardless of context, the woman was not rated more attractive when wearing red.

In the third attempt, researchers achieved the same negative results with 200 Americans.

We have to remember that the red effect can be more significant in real interactions than in the lab with photos. Maybe the color influences the behavior when the person is acting more flirtatiously.
