"The Tetris effect occurs when an activity to which people devote sufficient time and attention begins to overshadow their thoughts, mental images, and dreams...People who play Tetris for a prolonged amount of time may 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."
mostly this is happens with words. i will see a word and my mind will dissect it into as many other words as can be made from it. example: i have a poster that says RESPOND in my living room. my brain makes the words: ponders (BINGO!), pond, ponds, nod, nods, pore, pores, done, dones, drone, drones, etc etc). it is quite distracting as well, there are words everywhere. if i weren't such a feely person i would wonder if i were mildly autistic sometimes. so when the tetris effect starts coming on i know i've been playing a game too much and i back off. i havn't played scrabble in months and the effect has left so this week i started two new games and im sure i will exhaust the novelty of it until i start going wack a do with words. rinse repeat.
