Researchers in psychology discover benefits of Scrabble practice for word recognition

University of Calgary

Since competitive Scrabble players are expert at studying language, University of Calgary researchers sought to determine if and how players' techniques and training changed the process of reading words.

They tested competitive Scrabble players to understand the extent to which the players relied on the meaning and physical orientation of words in order to understand them as a part of the English language system. Their study shows, for the first time, that it is possible to develop visual word recognition ability in adulthood, beyond what researchers previously thought was achievable.

"The average literate adult relies on three components to process and read a word: sound, spelling and meaning," says Penny Pexman, professor of Psychology. "When we studied the Scrabble players, we found that there is significant flexibility in the tools they use to read words and that it can include the orientation of the word as well."

The Scrabble players in the study were able to recognize English words, compared to nonsense words 20 percent faster than non-Scrabble players. Researchers say competitive players, who dedicate large amounts of time to studying the 180,000 words listed in The Official Tournament and Club Word List, processed words more quickly and were better able to recognize words oriented vertically.

"Scrabble players have honed their ability to recognize words such that they have actually changed the process of reading words," says Ian Hargreaves, PhD Candidate in Psychology and lead researcher on the study. "They have done this in two ways. First the scrabble players showed less difference in the time it took to recognize a word as real when it was positioned vertically than they did for a horizontal word, whereas non-Scrabble players are much slower in reading vertically."

The second way is in recognizing words mainly in terms of their visual appearance, and less in terms of the words' meaning. Competitive Scrabble players' efficient recognition of letter sequences demonstrates why even non-English speakers are able to master the game.

Researchers were surprised to find that for scrabble players the meaning of the word had less impact on their ability to recognize and process a word.

"This is atypical," says Hargreaves. "Usually the meaning of the word would have a bigger impact a person's decision about whether or not it is a true word. This shows that one consequence of extensive Scrabble training is that Scrabble players don't tend to emphasize what the words mean. Words are most importantly plays in a game."
