Missing letter effect

In cognitive psychology, the missing letter effect refers to the finding that, when people are asked to consciously detect target letters while reading text, they miss more letters in frequent function words (e.g. the letter "h" in "the") than in less frequent, content words. Understanding how, why and where this effect arises becomes useful in explaining the range of cognitive processes that are associated with reading text. The missing letter effect has also been referred to as the reverse word superiority effect, since it describes a phenomenon where letters in more frequent words fail to be identified, instead of letter identification benefitting from increased word frequency. The method in which researchers utilise to measure this effect is termed a letter detection task. This involves a paper-and-pencil procedure, where readers are asked to circle a target letter, such as "t" every time they come across it while reading a prose passage or text. Researchers measure the number of letter detection errors, or missed circled target letters, in the texts. The missing letter effect is more likely to appear when reading words that are part of a normal sequence, than when words are embedded in a mixed-up sequence (e.g. readers asked to read backwards).…

The missing letter effect is more likely to appear when reading words that are part of a normal sequence, than when words are embedded in a mixed-up sequence (e.g. readers asked to read backwards). Despite the missing letter effect being a common phenomenon, there are different factors that have influence on the magnitude of this effect. Age (development), language proficiency and the position of target letters in words are some of these factors.
