Decoding Scrambled Words Under Specific Conditions – BrainStuff: Does Letter Arrangement Matter?Key Insights
- The common belief that scrambled words are easily readable when the first and last letters remain in place originates from a non-existent Cambridge University study, but there is some truth to it, according to research conducted by Graham Rawlinson from Nottingham University.
- The order of letters plays a crucial role in readability, with research indicating that letter scrambling can reduce reading efficiency by up to 36 percent, depending on where the jumbling happens.
- Our brains process all the letters of a word simultaneously and rely on context to comprehend jumbled words, showcasing our ability to adapt and deduce meaning from distorted text.
Have you ever come across this passage? "I couldn't believe that I could actually understand what I was reading: the phenomenal power of the human mind. According to a research team at Cambridge University" and so on.
Although this meme has circulated widely online, referencing a study from Cambridge University, we've found that the study doesn't actually exist — and the meme itself isn't entirely accurate. That said (or should we say "hwovere"), Nottingham University has some relevant commentary on the subject.
In a letter to New Scientist magazine in May 1999, Nottingham University graduate Graham Rawlinson suggested that randomizing the letters in the middle of words had "little or no effect" on readers' comprehension, provided that the first and last two letters of the word were intact. This likely forms the basis of the meme's truth.
Apart from that, the meme is riddled with inaccuracies. For example, letter order does matter. It significantly impacts the readability of text. One small study monitored the eye movements of 30 college students as they read sentences with scrambled letters. The study showed that transposing letters in the middle of a word reduced reading ability by 12 percent. When letters were scrambled at the end of a word, the reading rate dropped by 26 percent, and if the disruption happened at the beginning of a word, the reading rate fell by 36 percent.
Our capacity to comprehend words with jumbled letters in the middle hinges on our ability to infer context. Marta Kutas, a researcher at the Center for Research in Language at the University of California, San Diego, explains that context enables us to activate brain regions that anticipate expected outcomes. If you scan someone's brain while they hear a sound that leads them to expect a particular follow-up sound, you'll observe that their brain behaves as though the expected sound is already occurring. The brain gathers just enough information to make sense of the word you're looking at.
The same idea applies to both letters and words. Our brains handle all the letters in a word simultaneously and use them to provide context for each other. This is why we can even read words that contain NUMB3RS 1NST3AD 0F L3773RS. The numbers' resemblance to letters, combined with the surrounding context, makes them easier to understand despite being numbers.
You can still read scrambled words; it might just take you a bit more time to make sense of them.
