Tetris effect – Google changes the logo on 25th anniversary of Tetris Game
Posted on Jun 6, 2009
Tetris effect occurs when an activity to which people devote sufficient time and attention begins to overshadow their thoughts, mental images, and dreams. Google has created a special logo on the 25th anniversary of Tetris effect (see image). Tetris effect is named after the video game Tetris.
In the video game Tetris a player rotates and moves different falling tetrominoes, or shapes made up of four square blocks. If the player can arrange the shapes so there are complete horizontal lines of blocks without any gaps, those lines are eliminated. The object of the game is to eliminate as many lines as possible before the shapes fill the screen.
What are the symptoms of Tetris effect
- People who play Tetris for a long time might then find themselves thinking about ways different shapes in the real world can fit together, such as the boxes on a supermarket shelf or the buildings on a street. In this sense, the Tetris effect is a form of habit.
- They might also see images of falling Tetris shapes at the edges of their visual fields or when they close their eyes. In this sense, the Tetris effect is a form of hallucination.
- They might also dream about falling Tetris shapes when drifting off to sleep. In this sense, the Tetris effect is a form of hypnagogic imagery.
