It is sometimes also referred to “the theory of psychological reactance”, stating that the attempts to restrict a person’s freedom often produce a boomerang effect. One of the best examples of this effect often happens within the arguments of two persons wherein with the lack of information and ideas, the opposing person could take the damage meant for the other person.evil

  • Hawthorne Effect

 Also referred to Observer Effect is a type of reactivity in which individuals modify or improve an aspect of their behavior in response to their awareness of being observed. The original “Hawthorne Effect” study at Hawthorne Works suggested that the novelty of being research subjects and the increased attention from such could lead to temporary increase in workers’ productivity. The term was coined in 1950 by Henry A. Landsberger when analyzing earlier experiments from 1924-1932 at the Hawthorne Works (a Western electric factory outside Chicago). The Hawthorne Works had commissioned a study to see if their workers would become more productivity in higher or lower levels of light. The workers’ productivity seemed to improve when changes were made, and slumped when the study ended. It was suggested that the productivity gain occurred as a result of the motivational effect on the workers of the interest being shown in them. The more a person is supervised with a frequent change of tasks, the more the person becomes productive. It’s like a single person who’s a swordsman now, and could be an archer after few minutes. a person that could be anyone when supervised.


  • Rhyme-as-reason Effect

 Make a self-test about these two statements. Which would you think is more accurate: “What sobriety conceals, alcohol reveals.” And “what sobriety conceals, alcohol unmasks”. The Rhyme-as-reason Effect (or Eaton-Rosen Phenomenon) is a cognitive bias whereupon a saying or aphorism is judged as more accurate or truthful when it is rewritten to rhyme. In experiments, subjects judged variations of sayings which did and did not rhyme, and tended to evaluate those that rhymed as more truthful (controlled for meaning).
