Learning for social psychology

I'm sitting here learning for my test in social psychology and I thought I could share some funny facts I learned recently.

Fact 1: Former relationships have a big influence on later relationships cause we always compare former satisfaction levels with our recent relationship.

Fact 2: the Commitment of our relationship depends on Investment, satisfaction (which consists of function of costs, rewards and comparison level) and the comparison level. It's also important how high the comparison level for alternatives is

Fact 3: If someone accidentally destroys your vase it's better to let him pay for it than to say it doesn't matter because the person would feel horrible. The base of this is the so called equity theory

Fact 4: If you put people in smaller offices than they are used to they will work less than before and if you put them in bigger offices they will work more

Fact 5: the mere exposure effect says that the mere presentation of an unknown stimulus makes it more attractive

Fact 6: nice music makes you see people more attractive, displeasing music makes them more unattractive

Fact 7: when it's hot and crowded you think people are less attractive

Fact 8: The most important indicator for satisfaction in a relationship is analogy in attitude

Fact 9: The most important criteria for partnership selection for men is outer appearance and for women status

Fact 10: There are three dimensions of love: "intimacy, attachment and passion". The more there is of every dimension the bigger is the love but there can't be much passion when there is much intimacy for passion is a tool to increase intimacy, that's why people in longer relationships loose their passion some time

Fact 11: when a minority in a group says constantly that a transparency is green though it is obviously blue people start to think that it's really green

Fact 12: if a person sits in a room with insiders who are instructed to show no reaction and smoke starts to come out under the door they have the tendency to stay at their seat even when the smoke starts to become so thick that they can't see a thing

Fact 13: If you ask a small favor of someone and he helps you, the probability that he will help you a next time rises significant (that's called the foot in the door technique)

Fact 14: If you ask someone a really big favor, he declines and you asks him a smaller favor he tends to help you (that's called the door in the face technique)

Fact 15: you show a better performance for easy tasks just because people are attendant and a worse for  hard tasks

Fact 16: You tend to prefer your own group over others even if you have a loss of your total gain

Fact 17: you doesn't lower your aggression by letting it out, it increases instead

Fact 18: the mere presence of arms increases the aggression
