![]() The effect was named after Pygmalion, a sculptor in Greek mythology, who fell in love with a statue he made. ![]() According to Rosenthal, elementary school teachers might subconsciously behave in ways that influence the students. This led to the conclusion that teachers’ expectations have an impact on the students’ performance, especially at a younger age. Though all six grades showed a mean increase in test results in both control and experimental groups, the first and second grade showed a significant increase among the students whose names were given to the teachers. The students were given another IQ test at the end of the study. Instead, the teachers were given names of 20% of the students who were randomly chosen, and told that they could be “intellectual bloomers.” They gave students an IQ test the results of which were not disclosed to the teachers. Robert Rosenthal, Distinguished Professor of Psychology at the University of California, and Lenore Jacobson, an ex-principal of an elementary school in South San Francisco, conducted a study to test the hypothesis that a person’s reality can be influenced positively or negatively by other people’s expectations of that person. The higher the expectations, the more they try to perform better. ![]() ( source) 2 The “Pygmalion effect” is a psychological phenomenon in which a person’s performance depends on what others expect of them. Mathematicians such as Srinivasa Ramanujan and Friedrich Engels have reported dreaming of numbers or equations, the latter remarking “last week in a dream I gave a chap my shirt-buttons to differentiate, and he ran off with them.” A variation of the Tetris effect is the condition of “sea legs,” an illusion that the floor is rising and falling that people who’ve been on a boat feel after getting back onto land. The Tetris effect is also known to occur in people who participate in speedcubing, a competition that involves solving a variety of puzzles, especially the Rubik’s cube, and experience involuntary visualization of various moves to solve the cube. People who played it for long periods of time often find themselves thinking of fitting together buildings, boxes, and any other geometrical objects, hallucinating or dreaming about falling tetrominoes, or seeing them in the corner of their eyes. The effect was named after the video game Tetris in which the gamer has to manipulate falling tetrominoes to create horizontal lines without gaps. ![]()
