Pygmalion and Placebo Effect
edward sevume, Sweden, Member
As has been described in the text, the "Pygmalion effect
" is another expression for a self fulfilling prophecy - the expectation that you will do good since it is expected or fall from a bicycle in the corner since you expect to fall.
The placebo effect
is used in clinical evaluations where one group of two to be tested are given a toothless chemical substance from the tester and which in most cases attains a positive psychological effect as group expects positive effects as if they received the real chemical substance in the trial.
The Hawthorne effect
relates to the same view (as I understand your question) that when the work environment was analyzed the workers interpreted this interest as assessment or positive personal interest in what they were doing and thus this changed their motivation positively.
I would say that there is some positive expectation and evaluation of work done which affected their motivation and thus good results!
