Lynn & Mynier - 1933

AIM:to see if gestures used by waiters and waitresses on customers in a restraunt has an effect on tipping behaviour 

METHOD:Whilst taking orders from seated customers, waiters were instructed to either squat down (making more eye contact possible) or stand upright.

RESULTS:The waiters & waitresses who squatted down recieved larger tips than the waiters & Waitresses who stood upright.

CONCLUSION:The gesture of squatting down in a restraunt when taking orders has a positive effect on tipping behaviour.

EVALUATION:

- Size of the bill could have affected tipping behaviour. For eg. teh more the customers spent, they could have given larger tips as waiter had to work harder.

- It was unethical as customers were not aware that they were part of an experiment- deception 

- Extraneous variables - the appearence of the waiter/waitress, whether the customer found them attractive.

+ Practical applications (such as a waiter lowering their posture when taking orders to earn more more) can be gathered from the study

METHOD: One at a time, participants were asked to sit & have a conversation with another person (who was actually a confederate). Sometimes the confederate was the same sex & at other times the confederate was the opposite sex. The confederate sat at different distances & continually looked into the participants eyes.

RESULTS: Participants tended to break eye contact at a greater distance when the confederate was the opposite sex than when the confederate was of the same sex.

CONCLUSION: When having a conversation, people tend to feel comfortable having small personal space with members of the same sex

+ In a working enviroment, teachers need to be aware of a students personal spcae especiallt if they are members of the opposite sex.
