Interesting Psychological Facts

From an article on PsychTronics, a list that absolutely interests the psychologist in me.

1.When it comes to placebo, studies have found that a capsule works better than a tablet, and a syringe works better than a capsule (in terms of how successful the placebo effect is).

  1. A placebo effect can work even when the individual is aware that the substance they are taking is a placebo.
  1. Humans can live longer without food than they can without sleep.
  1. Even small noises can make your pupils dilate.
  1. By age 60, you will have lost half of your taste buds.
  1. If saliva cannot dissolve something, you cannot taste it.
  1. Your brain and your stomach are in constant contact with each other which is why some emotions affect our stomachs physically, especially distress.
  1. Since the existence of the internet, fewer people claim to be religious.

9. Chewing gum helps your memory to receive a higher test score.

10. The color purple or more specifically ‘lavender’ creates a soothing effect. It is also a great color to have for your bed spreads.

11. In one of Freud’s psychosexual stages, the phallic stage, children become interested in their own genitalia, their parents, and their friends. Accompanied with this stage is the term ‘penis envy’, this is defined as the female child’s realization/resentment that they do not have a penis.

12. Your Short Term Memory is an actual store in your brain, although it has a much more limited capacity than expected- it lasts approximately 20 seconds and can process five to nine things at one time.

13. Red makes anyone more sexually attractive, but I learned that wearing blue makes men especially more attractive to women.

14. Most human display hindsight bias, the tendency to claim that they have predicted an outcome before the event occurred.

15. Almost 70,000 thoughts a day hit the average human mind.

16. On average it takes 66 days to form a habit.\

17. If someone makes eye contact with you for 60% of a conversation they’re bored, 80% and they’re attracted to you and 100% of the time then they are threatening you.

18. Excessive stress can alter brain cells, structure and function.

19. Descriptive words used on questions eye witnesses are asked after seeing an event can effect how they remember the event later on. In other words influence what people remember.

20. The sense of falling involved in a dream actually comes from the brain falling asleep too fast and assuming it is dying. The sensation is essentially the brain giving itself an AED.

21. If you fake a smile, even when you’re in a bad mood, that smile will help you feel better and therefore make you happy.

22. Men are attracted to women with clear skin, bright big eyes, rosy lips, and lustrous hair because they are indicators of health and an optimal partner for reproduction.

23.Obsessive Compulsive Disorder is not just being a germiphobe. The disorder is obsessive unwanted thoughts and associations of unconnected events.

24. When you yawn and someone else yawns right after it means they were watching you and\or are attracted to you.

25. It is a myth that humans can only use 10% of their brain at any given point. We can actually utilize somewhere around 35% at once.

26. When focusing hard on a task, the human brain will completely block out other things going on, even if it’s right in front of them. It’s called selective attention.

27. Brains in some individuals produce more chemicals compared to others; this is why some people are considered more emotional than others.

28. Intelligence is partially based on genetics.

29.Though the placebo effect may trick people into thinking they are becoming healthier, it can also harm them in the sense that once they begin taking medications for things that don’t need it, they develop a resistance to that medication so that when they need it, it no longer works.
